dynofit Torsion Bar Keys 1-3in Front Lift Kit for 2020–2024 Silverado/Sierra 2500/3500 HD — Forged Adjustable with Shock Extenders

Dynofit forged torsion keys with shock extenders provide a reliable, adjustable 1–3" front lift for 2020–2024 Chevy Silverado and GMC Sierra 2500HD/3500HD 4WD trucks without changing CV geometry.

If you're upgrading tire size or need extra ground clearance while preserving factory driveline angles, this Dynofit kit is engineered to deliver a safe, OEM-friendly front lift. The package includes two precision-forged torsion keys, matching shock extenders brackets, and aluminum shock pads—designed specifically for 8-lug 2500/3500 heavy-duty pickups built between 2020 and 2024. Note: this kit is not compatible with Magnetic Ride Control systems.

How does this kit change ride height and vehicle geometry?

The torsion keys are adjustable to deliver between 1 and 3 inches of front lift while keeping the CV joints and steering geometry within factory-acceptable range. That preserves handling and reduces the risk of premature drivetrain wear common with improper lifts.

• True 1–3" adjustable range for precise leveling.
• Maintains factory CV angles to protect driveline components.
• Designed to avoid suspension bottom-out with larger tires.

What materials and manufacturing standards are used?

Dynofit uses CNC cold-forging on SAE 1045 steel to increase molecular strength, followed by a three-stage corrosion defense for long-term durability. Shock brackets are laser-cut steel with reinforced welds, and the shock pads are 6061-T6 aluminum with aerospace anodizing to resist corrosion without flaking.

• CNC-forged SAE 1045 steel torsion keys for superior strength.
• Triple-layer finish: zinc phosphate, electrostatic powder coat, UV topcoat.
• 3/8" laser-cut steel brackets and anodized 6061-T6 aluminum pads.

Will this kit let me run larger tires safely?

Yes—the Dynofit kit provides OEM+ clearance so many installations can accommodate 33"–35" tires without rubbing or suspension bottoming out, depending on wheel offset and backspacing. Proper alignment and checking brake/ABS line clearance are still recommended after installation.

• Compatible with a broad range of 33"–35" tire setups.
• Maintains safe clearance while preserving steering geometry.
• Installation checklist includes wheel fitment and alignment verification.

What comes in the box and what should I expect for installation?

The kit ships with two torsion key halves, two shock extender brackets, four shock absorber pads, and an instruction sheet. Basic mechanical skills and common tools are sufficient for a typical home garage install, but professional installation is recommended if you’re not familiar with torsion-bar adjustments.

• Complete kit: 2-piece torsion keys, 2-piece shock brackets, 4 shock pads, instructions.
• Hardware and finish built for long-term use under heavy-duty truck loads.
• Contact Dynofit support for missing parts or quality concerns.

Who is this for: This Dynofit leveling lift kit is for owners of 2020–2024 Chevy Silverado 2500HD or 3500HD and GMC Sierra 2500HD or 3500HD 4WD trucks who want a reliable, adjustable front lift to fit larger tires or improve stance without compromising driveline geometry. It's especially suited to drivers seeking a rugged, corrosion-resistant solution built to OEM-plus strength standards, and to installers who prefer a CNC-forged, vehicle-specific kit. Avoid purchasing if your truck is equipped with Magnetic Ride Control or you require rear lift components in the same purchase.
