KSP PERFORMANCE Torsion Bar Unloading Tool for Chevy/GMC 2500HD 3500HD — Heavy-Duty Forged Steel C-Clamp, 1" Hex Drive

The KSP Torsion Bar Unloading Tool is a heavy-duty C-clamp style kit engineered to safely remove and install torsion keys on 2011+ Chevy Silverado and GMC Sierra 2500/3500 HD and compatible GM trucks.

If you work on heavy-duty Chevy or GMC pickups, this specialized torsion key removal and installation tool streamlines suspension service by allowing technicians and DIYers to unload torsion springs without extra U-bolt disassembly. Built from forged steel with a reinforced anti-twist C-frame, the tool includes an enlarged pressure core and extended hex drive to reduce slippage and withstand the high loads found on 6-lug and 8-lug trucks.

Which vehicles and torsion setups does this tool support?

This KSP tool is designed to fit a range of GM platforms, most notably 2011+ Chevy Silverado and 2011+ GMC Sierra 2500/3500 HD models, and many earlier Yukon XL and similar trucks. Always confirm fitment with your model year and torsion key configuration before purchase.

• Compatible with 6-lug and 8-lug heavy-duty GM trucks
• Commonly fits 2011+ Silverado/Sierra 2500HD and 3500HD
• Can be used on some 2000–2010 Yukon XL and related models
• Check vehicle-specific clearances and torsion bar diameter before use

How does the tool make torsion key removal safer and faster?

The widened pressure core and extended drive hex stabilize the tool under load to minimize slippage during removal and installation. The anti-twist C-frame geometry and heat-treated forged steel construction resist bending so you can apply high torque without tool deformation.

• Enlarged pressure core spreads load and prevents concentrated wear
• Extended 1" (25mm) hex drive reduces wrench slippage
• Anti-twist C-frame design limits tool rotation under torque
• Powder coating and heat treatment increase corrosion and wear resistance

What are the key dimensions and hardware specs I need to know?

The kit’s main bolt features a 7/8" (22mm) thread pitch and an overall length of 8.07" (205mm), with a 1" (25mm) hex head. Handle thickness and frame sizing are optimized for heavy truck torsion springs while maintaining user control.

• Thread pitch: 7/8" (22mm)
• Bolt overall length: 8.07" (205mm)
• Bolt hex size: 1" (25mm)
• Handles thickness: 1.18" (30mm) for solid grip and leverage

What construction features improve longevity and reliability?

Built from forged steel and given heat treatment and powder coating, the tool is engineered for repeated heavy use. Structural reinforcements and anti-twist geometry reduce fatigue and failure risk compared with lighter, stamped alternatives.

• Forged steel main body resists bending and cracking
• Heat-treated areas where high stress concentrates
• Powder-coated finish for corrosion protection
• Designed to outperform OEM-style removal tools in durability

Who is this for: mechanics, fleet technicians, and experienced DIY truck owners who service heavy-duty Chevy and GMC suspension systems will benefit most. If you routinely replace torsion keys, realign suspension geometry, or perform lift and leveling jobs on 2500HD/3500HD trucks, this KSP PERFORMANCE unloading tool reduces labor time and increases safety during torsion spring disassembly and reassembly. If you are unsure about compatibility or installation steps, consult a service manual or professional installer before use. KSP PERFORMANCE backs this tool with a 30-day refund and 12-month replacement support if defects arise.
