Our King 3.0 Performance kit for the  '07-18 Chevrolet/GMC 1500 takes our standard King suspension system to the next level. We utilize the same Camburg 1.25" uniball upper arms but combine them with KING’s 3.0 series front coilovers with compression adjusters and their rear 3.0 bypass shocks. This combination of parts not only improves the ride and handling on-road but more so off-road with the larger diameter shocks and external reservoirs. With the upper arms these shocks increase wheel travel. Improved ride both on and off-road Eliminates weak upper ball-joint Increased wheel travel Corrected suspension geometry Made in the USA Note: some factory wheels will not clear the upper arm and may require a wheel spacer. We highly recommend aftermarket wheels with a zero offset with all our Chevrolet kits for optimum performance and fit. 0-2.5" lift Improved ride and handling Increased wheel travel Made in the USA Note: some factory wheels will not clear the upper arm and may require a wheel spacer.
