RockTrix RT110 20 Inch Wheel Overview
RockTrix RT110 wheels are designed for Silverado/Sierra 2500HD and 3500HD models, with broad compatibility for GMC Sierra 2500HD and 3500HD from 2011 onward. The 20×9 wheel size features a -12 offset (4.5″ backspacing), promoting a bold stance when paired with appropriate 20″ tires. The finish is matte gunmetal with a durable clear coat to withstand harsh weather. A cone-seat lug nut is required for installation, compatible with OEM and aftermarket cone-seat lug nuts under 1.25″ diameter. Tightening to manufacturer torque specifications is essential for safety and performance. The wheel uses an 8×180 bolt pattern and center bore of 124.1mm, providing reliable fit on 2500HD platforms when paired with the correct tire choice.
The product is sold as a single wheel. It is important to verify tire size compatibility to avoid rubbing and ensure full clearance within the front fender well and suspension components. The wheel is oriented for users seeking a rugged look that complements heavy-duty tires and a lifted or leveled suspension. Proper lug nut selection is necessary to maintain wheel integrity and safe operation under load.
KSP 2 Inch Wheel Spacers Overview
KSP Performance spacers provide a universal fit for Silverado 2500, 2500HD, and Sierra 2500HD models with 8×180 bolt patterns. The spacers have a 130mm hub bore and are 2″ thick, designed to work with 8×180 wheels. They are crafted from 6061-T6 aluminum billet for strength and light weight, with heat-treated (hardened) 10.9 grade bolts to minimize vibration risk. Black anodized coating adds corrosion resistance. The set includes two spacers and a thread locker, with a recommended torque range of 85-95 ft-lbs. Always ensure compatibility with your tire size and vehicle configuration, especially when adding spacers to maintain safe steering and suspension alignment.
Installing spacers can alter wheel track width, potentially improving stance and clearance for larger tires or wider wheels. However, misalignment or improper torque can lead to increased stress on lug nuts and wheel studs. Verify that the spacers are compatible with your specific wheel offset and the vehicle’s braking and suspension geometry before purchase.
RockTrix RT110 18 Inch Wheel Overview
This RockTrix RT110 wheel is an 18×9 inch option with a -12 offset (4.5″ backspace) and a center bore of 124.1mm. The matte black finish with a protective clear coat provides durability in challenging climates. Like the 20″ version, it uses an 8×180 bolt pattern and is intended for 2011+ Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD applications. The wheel is sold as a single piece and requires cone-seat lug nuts for installation. It is compatible with cone-seat OEM lug nuts and aftermarket options, ensuring secure mounting when installed to manufacturer torque specs. This size can offer a balanced blend of off-road capability and everyday on-road comfort, especially when paired with the right tire configuration.
When selecting tires for these wheels, consider the overall diameter and tread pattern to maintain speedometer accuracy and avoid rubbing at full lock. The 18″ wheel can support tires that provide improved sidewall protection and grip on rough terrain, while maintaining a practical feel for highway use on heavy-duty trucks like the Sierra 2500HD.
KSP 2″ Rear Lift Kit Overview
The KSP Rear Lift Kit is designed for 2011+ Silverado/Sierra 2500HD models, with a 2″ lift block and upgraded square U-bolts. It is not intended for dually configurations or vehicles with factory overload springs, and it does not fit 3500 models. The kit uses a black powder-coated finish for rust resistance and features CNC-machined steel components to bolster durability. The extended U-bolts (M16x1.5) provide robust mounting and improved safety under heavy loads. This kit helps achieve higher wheel clearance for larger tires and can complement a leveled or lifted stance for better off-road performance and heavy towing stability.
Installations should follow torque specifications for the U-bolts and ensure proper alignment after lifting. While beneficial for appearance and clearance, a lift can affect ride characteristics, steering feel, and payload distribution. Consider combining with suitable tie-ins to maintain steering geometry and braking performance with heavier tire options.
RETRUE Rear Air Bags Suspension Kit Overview
The RETRUE airbag suspension kit provides a load leveling capacity of up to 5,000 pounds, suitable for 2011-2026 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD models. This kit replaces or supplements traditional springs to reduce squat under heavy loads and stabilize the vehicle during towing. It is designed to be easy to install, with pre-drilled holes and labeled parts, enabling a drill-free setup in many cases. Hydrophobic and oleophobic coatings help resist fingerprints and wear, while a multi-layer design improves durability. The kit is a practical option for owners who tow heavy trailers or regularly carry heavy payloads, offering improved ride quality and leveling capabilities across a range of road conditions.
When evaluating air bag suspensions, consider air compressor availability, ride height adjustability, and compatibility with existing ride height sensors or leveling systems. While offering substantial load support, air bag kits can require more ongoing maintenance than traditional springs and may influence braking response, tire wear, and ride stiffness depending on air pressure settings and usage patterns.
Buying Guide: Tire, Wheel, and Suspension Considerations
Overview: The GMC Sierra 2500HD benefits from wheels, spacers, and suspension components that optimize load handling, stability, and off-road capability. When selecting gear, assess fitment compatibility (bolt pattern, hub bore, offset), tire size compatibility to prevent rubbing, and the intended use (daily driving, towing, or off-road).
Fitment and Compatibility: Confirm the vehicle year, trim, and drivetrain to ensure the wheel offset and backspacing suit the Sierra 2500HD. For spacers, verify the hub bore and stud pattern, and ensure proper torque with a calibrated torque wrench. If lifting or leveling, check clearance for brake calipers, suspension components, and wheels with chosen tire sizes.
Load Capacity and Towing: For heavy-duty use, consider air bag suspensions or load-leveling kits to maintain ride height under load. Pay attention to installation complexity and the impact on ride quality. High-quality lift blocks and U-bolts should be paired with reinforced mounting hardware to ensure safety under load.
Durability and Maintenance: Wheels with durable finishes resist corrosion in tough environments. Aluminum spacers and lift components should be treated for rust resistance. Regular inspection of lug nuts, bolts, and fasteners is recommended, especially after off-road use or heavy towing.
Cost vs. Benefit: While larger wheels and lifts improve appearance and clearance, they can affect ride comfort, fuel economy, and speedometer accuracy. Weigh the performance gains against maintenance and potential warranty considerations when choosing wheels, spacers, and suspension upgrades.
