Product Information

H&R Super Sport Springs are a progressive rate lowering spring kit with more drop than the Sport Spring. The kit drops the vehicle approx. 1.7 in at the front and approx. 2.4 in at the rear (Shelby GT500 2011-2014: approx. 1.9 in front and 1.7 in rear), trimming the fender gap and lowering the center of gravity to reduce body roll while keeping a comfortable ride. The springs are made from (hf) 54SiCr6 spring steel, shot-peened, and each one is tested before it leaves the ISO 9001 certified H&R plant in Germany.
