Our Max-Torsion Key Lift Kits are engineered with twice the strength of the factory system and precision indexed to lift your truck without sacrificing ride quality. This kit replaces your factory torsion key and is precision indexed to lift and level your front end any amount from 1" to 3".

For the rear of your vehicle, we are proud to introduce the New 2019 Low Weight HD Structure Steel Blocks. Using Heavy-Duty GMAW seam and fillet welding processes we reinforced it's structure with a 1/4" Thick CNC Plasma Cut Center Support Structure and a 3/4th Center Pin to ensure stability, perfect fitment and easy installation. LAB Tests have shown these blocks can withstand an astonishing load of almost 60,000 lbs with no yielding or deformation observed!

We've also made sure the extended U-bolts we provide rise to expectation, being ISO 9001 certified and stamped. A zinc phosphate coating is applied to them which is 5 times more corrosion resistant than typical zinc plating in accordance with ASTM B117 testing. Zinc phosphate coating is a multi-phase process commonly used in military applications for components in harsh environments and extreme weather conditions. In addition to the superior corrosion resistance, the zinc phosphate coating process requires less heat, helping to maintain the original heat treatment and hardness of the material.

We complete this kit with high grade shock extenders to provide our customers with the option to reuse the vehicle's factory shock absorbers & avoid the need to purchase expensive aftermarket extended shocks and our specifically u-Shaped Torsion Max Tool which covers both sides of the cross member firmly to distribute load evenly and safely replace the vehicle's torsion keys.

NOTES:

 * Front torsion keys are adjustable anywhere from 1" to 3".
** An alignment is always recommended after altering the height of your vehicle.
