PROFORMANCE SUSPENSION GM 2011-17 COILOVER CONVERSION LIFT KIT
10″+ KITS WILL SHIP IN 4-6 WEEKS DUE TO KING SHOCKS LEAD TIME.
PROFORMANCE SUSPENSION IS 100% MADE IN THE USA!
This kit is a coilover conversion to remove the torsion bar style factory suspension on the 2011+ GM 2500/3500 trucks. The kit comes with Proformance Suspension custom fabricated boxed upper and lower control arms along with our fully fabricated shock towers. We have paired this kit with a Cognito Motorsports lift including their differential drop brackets, lower control arm drop brackets, spindles, other front lift/steering components and rear block/u-bolts.
The front shocks are King 2.5″ (with reservoir) coilovers with custom valving for on and off road use. The rear shocks are King 2.5″ (with reservoir) custom valved shocks for the best possible ride quality with your factory or aftermarket leaf springs (upgrade option). These shocks will come blue and polished with blue springs. (Black will be available soon. Black can currently be requested for an additional lead time and fee.)
Never feel the rough torsion bar bounce again with our completely proven and tested coilover conversion using the best names in the industry!
**Cutting and welding is required with the installation of this kit.
