Performance valve springs for Drift/Drag applications, for Nissan SR20DET

Picture coming soon!
SR20DET Valve springs designed for Drift/Drag High Hp applications

Capable of .7mm more lift
22 lbs/in more spring rate

Peak Performance has had excellent results with the current springs. But we are always in search of better parts. So we pushed the limits, so we are now introducing the best valve spring we could find.

The new valve springs are now chambered, stress relieved and now comes with a custom Gold surface enhancement process. It provides a smoother isotropic surface that has higher residual stress compared to non treated springs. Basically it means it can survive longer at very high stresses and withstand more rpm.

What else was done to the springs? We increased the spring rate, used better material, and designed the spring for higher lift cams! That means the chance of spring failure is very minimal especially when those Drift/Drag guys are bouncing the car off the rev-limiter.
