The ReadyLIFT 66-3011 Torsion Bar Key Kit is a precision-engineered suspension upgrade designed to raise the front of torsion bar-equipped trucks while maintaining factory ride quality. Featuring re-engineered forged torsion adjustment keys and shorter bolts to prevent over-rotation, this kit is ideal for 2WD and 4WD GM HD trucks.
Constructed from high carbon steel, these keys exceed OEM strength standards and offer a lifetime guarantee. They are manufactured with extremely tight tolerances—based on GM blueprint specs (17/1000 THS)—to enhance contact between the key and bar. This increases structural integrity and ensures smooth, reliable performance. Some vehicle-specific kits may also include shock relocation brackets. Installation may require light mallet tapping due to precision fitting.
