KSP PERFORMANCE 1-3" Front Torsion Key Kit for Silverado/Sierra 2500HD 3500HD — Forged Adjustable Lift, Maintains Ride

This forged, adjustable torsion key set is engineered to give heavy-duty Chevy and GMC trucks a factory-like ride while raising the front end for a level stance and extra tire clearance. Designed specifically for 2020–2026 Silverado and Sierra 2500HD/3500HD 4WD models (8-lug), the kit is not compatible with Magnetic Ride Control systems. KSP used 3D scanning of vehicle suspension geometry to produce precise fitment and replaceable aluminum pads, delivering lasting strength and corrosion resistance.

How much lift and adjustment does the kit provide?

The KSP torsion keys are adjustable from 1" up to 3" in front lift, allowing you to dial in the vehicle attitude for a level look or to fit larger tires. Adjustment is mechanical; turning the key changes the torsion bar preload and ride height without changing ride quality when used correctly.

• Adjustable range: nominally 1"–3" front lift
• Enables larger tire fitment and improved ground clearance
• Maintain factory ride characteristics when properly adjusted
• Fine-tune stance for towing, payload, or visual preference

Will this fit my Silverado/Sierra and what are the vehicle exclusions?

This set fits 4WD 2020–2026 Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks with 8-lug wheels. It will not fit models equipped with Magnetic Ride Control or vehicles outside the specified model years and drivetrain configurations.

• Compatible: 2020–2026 Chevy Silverado 2500HD & 3500HD 4WD
• Compatible: 2020–2026 GMC Sierra 2500HD & 3500HD 4WD
• Not compatible: vehicles with Magnetic Ride Control
• Designed for 8-lug pickup applications

What materials and manufacturing methods ensure durability?

The torsion keys are forged from high-strength steel for superior load resistance and long service life, while a black powder coat finish improves corrosion protection. KSP supplies four 6061-T6 aluminum pads that are naturally oxidized to resist rust and provide a stable interface between key and suspension components.

• Forged steel keys for increased tensile strength and longevity
• Black powder coat for enhanced rust resistance
• 6061-T6 aluminum pads with natural oxidation to prevent corrosion
• 3D-scanned design for accurate fit and consistent performance

How difficult is installation and what tools or steps are required?

Installation is designed for a home mechanic with common tools and generally takes only a couple of hours. No cutting, welding, or other permanent modifications are required; the kit works with existing suspension hardware and allows you to adjust ride height after installation.

• Estimated install time: about 2 hours for a competent DIYer
• No cutting or vehicle modification needed
• Uses factory mounting points and hardware where applicable
• Final ride-height tuning done by rotating the torsion keys

KSP PERFORMANCE backs this torsion key set with a customer care promise that includes a 30-day refund option and a 12-month replacement warranty, so buyers have added protection if parts arrive damaged or defective.

Who is this for: Truck owners who drive 2020–2026 Chevy Silverado or GMC Sierra 2500HD/3500HD 4WD models and want a straightforward, durable front leveling solution to improve stance, fit larger tires, or increase ground clearance without altering suspension geometry. It’s a practical choice for DIY installers, fleet maintainers, and enthusiasts seeking dependable, bolt-on lift and adjustability while preserving ride quality.
