CV angles, O.E. track-width, thats just a few of the many reasons CST is known as the 2500HD specialists. You could also say they paved the way for sub-frame style lift kits, twenty years ago and long before the current trend.

(Stock Torsion Location) kit uses a one piece sub-frame, fabricated steering knuckles, steering drop down and will retain the factory handling! CST has incorporated their experience in off-road racing and trophy truck quality engineering to ensure that their suspension will have increased strength, performance, overall build integrity, and perform better than stock. Throughout the initial design and R&D process CST made sure to retain the factory O.E. suspension geometry and design attributes! The S.T.L. (Stock Torsion Location) 6-8" adjustable kit will include a one-piece gusseted sub-frame with a steel full size differential skid plate, fabricated steel, CNC machined front steering knuckles, high strength steering drop center-link with heim jointed support links to minimize wear of the factory idler and pitman arms, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, all of the necessary install hardware. This kit also includes the hand built S.T.L. front brackets, allowing you to keep the torsion x-member in the stock location! Included are (4) 2.0 Emulsion Shocks.
