KSP PERFORMANCE Torsion Bar Unloading Tool for Chevy GMC 2500/3500HD — Heavy‑Duty C‑Frame, 1" Drive Hex

The KSP Torsion Bar Unloading Tool is a heavy-duty C-frame and C-clamp style kit that safely unloads, removes, and installs torsion keys on 6-lug and 8-lug Chevy and GMC 2500/3500 trucks.

When servicing torsion bars on late-model GM heavy-duty pickups you need a tool built for high torque, precise alignment, and repeatable safety. This KSP tool is forged from hardened steel, fitted with an enlarged pressure core and extended drive hex to reduce slippage, and sized specifically for many Chevy and GMC 2500HD/3500HD, Yukon XL, and similar models. It replaces risky makeshift methods and eliminates the need to dismantle U-bolts for most torsion key jobs.

Which vehicles and torsion setups does this tool actually fit?

This tool is designed for GM heavy-duty torsion applications. It fits many 2011+ Chevy Silverado and 2011+ GMC Sierra 2500/3500 HD models, earlier GMT800 Yukon XL trucks, and other similar trucks with 6-lug or 8-lug torsion key assemblies. Check fitment specifics against your model year and suspension type before purchase.

• Compatible with 6-lug and 8-lug GM torsion key systems
• Common fit: 2011+ Silverado/Sierra 2500HD and 3500HD
• Also fits many 2000–2010 Yukon XL and comparable GM chassis trucks
• Confirm vehicle year and torsion assembly before use

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

The tool unloads torsion springs in a controlled way so parts can be removed or installed with minimal risk. Its anti-twist C-frame and enlarged pressure core stabilize the load under high torque, while the extended hex drive reduces slippage during operation, allowing one technician to work more quickly and more confidently.

• Forged-steel C-frame resists bending under heavy loads
• Enlarged pressure core spreads load to prevent slipping
• Extended 1" drive hex improves tool engagement with impact or breaker bar
• Eliminates extra U-bolt disassembly in many repairs

What are the tool’s key specifications and construction details?

The KSP torsion tool is engineered for workshop durability and repeatability. It uses heat-treated, powder-coated forged steel and specific thread and dimension standards so it fits and performs reliably in heavy-duty shop environments.

• Thread pitch: 7/8" (22 mm); bolt length: 8.07" (205 mm)
• Bolt hex size: 1" (25 mm); handle thickness: 1.18" (30 mm)
• Anti-twist C-frame design for torsion spring service
• Heat-treated, powder-coated finish for corrosion and wear resistance

How should I use and maintain the tool to get the best life from it?

Use the tool with the correct torque method — breaker bar or impact driver where appropriate — and follow OEM safety steps for supporting the vehicle and releasing torsion springs. After use, clean debris, lightly lubricate threads, and store dry to preserve the powder-coated surface and thread integrity.

• Always support vehicle safely and follow torsion spring safety procedures
• Use correct 1" driver and torquing technique to avoid tool damage
• Clean and lightly lubricate threads after each use
• Inspect C-frame and core for wear before reuse
