Unlocking the Perfect Fit: What Leer Truck Cap Fits Your 2013 GMC 2500 Sierra?

Why Invest in a Truck Cap for Your 2013 GMC 2500 Sierra?

Before diving into specific Leer models, let’s briefly consider why a truck cap is such a valuable addition. A cap transforms your open truck bed into a secure, weather-protected, and often climate-controlled storage area. This is invaluable for tools, gear, groceries, or even for creating a comfortable sleeping space during camping trips.

Beyond protection, a well-chosen cap can also improve your truck’s aerodynamics, potentially leading to slight fuel efficiency gains. It also adds a layer of security, keeping your valuable items out of sight and locked away from potential theft. Ultimately, a truck cap significantly expands the versatility and utility of your GMC Sierra.

Understanding Your 2013 GMC 2500 Sierra’s Bed: The Crucial First Step

The single most critical factor in determining truck cap compatibility is your truck’s bed size. The 2013 GMC 2500 Sierra, being a heavy-duty pickup, was available with a couple of bed length options. You absolutely must measure your truck bed accurately before looking at any cap.

Typically, the 2013 GMC 2500 Sierra offered two primary bed lengths:

• Standard Box (or Short Box): Approximately 6.5 feet (around 78-79 inches).
• Long Box: Approximately 8 feet (around 96-98 inches).

To measure your bed, use a tape measure from the inside of the bulkhead (the wall closest to the cab) to the inside of the tailgate. Do not measure along the top rail, as this can lead to inaccuracies. Your 2013 Sierra is part of the GMT900 platform, which means specific contours and dimensions that Leer designs its caps to match precisely. Knowing your bed length is non-negotiable for a perfect fit.

The Leer Difference: Why Choose Leer for Your Sierra?

Leer has been a trusted name in truck caps for decades, known for its commitment to quality, innovation, and a wide range of styles. When you choose a Leer cap, you’re investing in a product that is:

• Durable: Constructed from high-quality fiberglass, Leer caps are built to withstand harsh weather conditions and the rigors of daily use.
• Secure: Most Leer caps come with robust locking mechanisms, providing excellent security for your cargo.
• Stylish: Leer offers various designs that seamlessly integrate with the lines of your 2013 GMC 2500 Sierra, enhancing its overall aesthetic.
• Feature-Rich: From interior lighting to roof racks and carpeted headliners, Leer provides a plethora of options to customize your cap to your specific needs.

Based on my experience, Leer’s paint-matching process is also exceptional, ensuring your new cap looks like it came straight from the factory with your truck. This attention to detail is a significant reason why many truck owners opt for Leer over other brands.

Top Leer Truck Cap Models for Your 2013 GMC 2500 Sierra

Leer offers a range of models, each with distinct features and profiles. The exact availability might vary slightly based on the dealer and the year, but generally, these are the most common and suitable Leer caps for a 2013 GMC 2500 Sierra.

1. Leer 100R (or 100RCC for Commercial Grade)

The Leer 100R is often considered their classic, entry-level model, and it’s incredibly popular for a good reason. This cap offers a cab-high profile, meaning its roof line is flush with the cab of your 2013 GMC 2500 Sierra. This design provides a sleek, integrated look, almost as if it were an extension of your truck’s original body.

The 100R typically features a recessed frameless rear door, fixed side windows, and a basic interior. It’s an excellent choice for truck owners who need reliable weather protection and security without excessive bells and whistles. For those using their Sierra for work, the 100RCC (Commercial Cap) variant of the 100R offers heavier-duty construction and more commercial-focused options like solid sides and toolboxes. This model is a workhorse, perfect for everyday utility.

2. Leer 180

If you need a bit more cargo space than a cab-high cap offers, the Leer 180 is an outstanding option. This model features a mid-rise design, meaning its roof line is slightly higher than your truck’s cab. This extra height provides noticeably more vertical storage capacity, making it easier to haul larger items like furniture, taller coolers, or additional equipment.

The 180 maintains a relatively sleek appearance despite its increased height, blending well with the robust lines of the 2013 GMC 2500 Sierra. It often comes with larger side windows, which can be fixed or sliding, depending on your preference. The additional cubic footage makes the Leer 180 a popular choice for campers, contractors, and anyone who frequently hauls bulky gear.

3. Leer 122

For those who prioritize maximum cargo volume above all else, the Leer 122 is the ultimate choice. This model is Leer’s high-rise cap, featuring a significantly elevated roofline that maximizes interior height. The extra space is particularly beneficial for accommodating large tools, recreational equipment, or creating a spacious interior for truck camping.

The Leer 122’s distinctive design often includes a deeper side skirt and a more pronounced rear door. While it doesn’t offer the same sleek profile as the 100R, its functionality is unmatched for specific needs. If you regularly transport items that demand extra vertical clearance, or if you plan to convert your truck bed into a full-fledged mobile workshop or living space, the 122 is designed to deliver.

Beyond the Model: Essential Compatibility Checks

Even after selecting a Leer model, there are more factors to consider for a truly perfect fit on your 2013 GMC 2500 Sierra.

• Bed Length is Paramount: We cannot stress this enough. A Leer cap designed for a 6.5-foot bed will not fit an 8-foot bed, and vice versa. Always double-check your measurements against the cap’s specifications.
• Truck Cab Type: While less critical for cap fit than bed length, the cab type (Regular Cab, Extended Cab, Crew Cab) often dictates the available bed lengths for your 2013 Sierra. Ensure you’re matching the cap to the bed, not just the cab.
• Generation Specifics: Your 2013 Sierra belongs to the GMT900 generation (2007-2013). Leer designs its caps with specific contours to match the tailgate, bed rails, and cab of this generation. A cap designed for an older or newer generation Sierra will likely not fit properly. The angles and curves around the cab and tailgate are unique to each generation.

Key Features to Consider When Choosing Your Leer Cap

Beyond the basic model, Leer offers a vast array of options and features that can significantly enhance the usability of your cap. When making your selection for your 2013 GMC 2500 Sierra, think about how you’ll primarily use the truck and what features would be most beneficial.

• Window Options:
  • Fixed Windows: Standard, offer good visibility but no ventilation.
  • Sliding Windows: Allow for airflow, great for pets or camping. Some even have screens.
  • Tip-Out or Vent Windows: Provide excellent ventilation and often easier cleaning.
  • No Windows (Solid Sides): Ideal for commercial use where security and advertising space are priorities.
• Rear Door Mechanism:
  • T-Handle Lock: Common, reliable, and secure.
  • Rotary Latches: Can offer a smoother, more integrated look.
  • Keyless Entry: A convenient upgrade, often linked to your truck’s remote.
• Interior Lighting: Essential for finding items in the dark. Options range from simple battery-powered dome lights to bright LED strip lighting, often powered by your truck’s electrical system.
• Roof Rack Options: If you plan to carry ladders, kayaks, bikes, or extra gear on top of the cap, a factory-installed roof rack system (like Thule or Yakima) is a must-have. These are robust and designed to handle significant weight.
• Carpeted Interior: Not just for aesthetics, a carpeted headliner helps insulate the cap, reduces condensation, and protects delicate cargo from scratches. It also significantly dampens road noise.
• 12V Power Outlet: Extremely useful for charging phones, running portable refrigerators, or powering other accessories inside the cap.
• Front Sliding/Removable Window: This allows you to clean your truck’s rear window and the front of the cap, and provides pass-through access to the cab.

Pro tips from us: Always consider how often you’ll access the cap and what kind of items you’ll store. If you have pets, sliding windows are non-negotiable. If you’re a contractor, solid sides and internal toolboxes might be a game-changer.

New vs. Used Leer Caps for Your 2013 Sierra

Deciding between a new and used Leer cap for your 2013 GMC 2500 Sierra is a significant financial consideration. Both have their advantages and disadvantages.

New Leer Cap:

• Pros: Perfect paint match, full warranty, all the latest features and options, no wear and tear, professional installation often included. You get exactly what you want.
• Cons: Higher upfront cost.

Used Leer Cap:

• Pros: Significantly more affordable, immediate availability (no waiting for manufacturing/paint), environmentally friendly.
• Cons: Finding the exact match for your 2013 GMC 2500 Sierra’s bed length and color can be challenging. It might have dings, scratches, or worn seals. No warranty. Installation might be DIY or an added cost.

If you opt for a used cap, here are some critical tips:

1. Verify Fit: Bring your 2013 GMC 2500 Sierra to physically test the cap. Even if the seller says it fits, double-check.
2. Inspect Thoroughly: Look for cracks in the fiberglass, especially around the corners and mounting points. Check the condition of the seals, windows, and locking mechanisms.
3. Check Wiring: If it has interior lights or a third brake light, ensure the wiring is intact and functional.
4. Paint Match: Unless you plan to repaint, be prepared for a less-than-perfect color match if you buy a used cap not originally from your truck.

Installation & Maintenance Tips

Installing a Leer truck cap on your 2013 GMC 2500 Sierra can be a straightforward process, but it requires careful attention to detail.

• Professional Installation: This is highly recommended. Authorized Leer dealers have the experience, tools, and proper sealing materials to ensure a watertight and secure fit. They’ll also handle the wiring for lights and locks.
• DIY Installation: If you choose to install it yourself, ensure you have assistance, as caps are heavy and cumbersome. You’ll need appropriate clamps to secure it to the bed rails and proper weather stripping to prevent leaks. Wiring for the third brake light and interior lights will require tapping into your truck’s electrical system, which can be complex.
• Maintenance: Regularly inspect the seals around the base of the cap and the windows for any signs of wear or cracking. Apply a UV protectant to the fiberglass to prevent fading and keep it looking new. Lubricate hinges and locks periodically.

Where to Purchase Your Leer Truck Cap

For new Leer truck caps, your best bet is an authorized Leer dealer. These dealerships specialize in Leer products, have trained staff, and can offer professional installation and warranty support. They can guide you through all the options and ensure you get the perfect cap for your 2013 GMC 2500 Sierra.

For used caps, check online marketplaces like Craigslist, Facebook Marketplace, or dedicated truck accessory forums. Be prepared to travel to inspect the cap in person.

Common Mistakes to Avoid When Buying a Truck Cap

Based on my years in this industry, I’ve seen customers make these common errors time and again:

1. Ignoring Bed Measurements: This is the biggest mistake. Assuming a cap will fit because it "looks about right" or was on "a similar truck" is a recipe for disappointment. Always measure your bed, and verify those measurements against the cap’s specifications.
2. Not Checking Bed Rail Condition: If your 2013 Sierra’s bed rails are dented, warped, or have aftermarket bed rail caps that interfere, it can prevent a proper seal and fit. Ensure your bed rails are clean and flat.
3. Buying Without Seeing (Used): Never buy a used cap sight unseen. Pictures can be deceiving, and you need to inspect for damage, wear, and actual fitment.
4. Neglecting Installation: A poorly installed cap can leak, rattle, or even shift during driving. Don’t cut corners on installation; it’s just as important as the cap itself.
5. Forgetting About Future Needs: While a basic cap might suffice now, consider if you’ll need roof racks, extra height, or more secure locks in the future. Upgrading later can be more expensive than getting the right features from the start.

Pro Tips from Us for Your Leer Cap Journey

• Visit a Dealer: Even if you plan to buy used, visit an authorized Leer dealer first. See the different models in person, ask questions, and get a feel for the features. This will clarify what you truly need.
• Ask About Current Promotions: Dealers often run promotions or have package deals that can save you money on a new cap and installation.
• Consider Resale Value: A well-maintained Leer cap can add value to your 2013 GMC 2500 Sierra, especially if it’s a popular model and color.
• Don’t Rush the Decision: This is an investment. Take your time, do your research, and ensure you’re confident in your choice.
