SPRING & SPRING SEATS

PERFORMANCE VALVE SPRING SETS A Spring is a Spring. Right? Wrong! All Springs are not equal. Valve Springs perform the job of returning the valve to its seat hundreds of thousands of times in the most severe conditions. JIMS ® Springs are made from the highest grade materials, heat treated to the highest industry standards, then torture tested on the street and the track to ensure not only consistent qual- ity, but unmatched performance as well. JIMS Spring Kits incorporate an interference double Spring design with a damper. The damper keeps the inner and outer Spring coils from locking together, while controlling power robbing harmonics in the Spring.

SPRING SETS ARE SOLD IN SETS OF 4 FOR ONE ENGINE
