When using JRi Shocks for drag racing that have a solenoid operated air valve to lock in the low speed rebound on launch, the hose arrangement will require Y-adapter to fit 5/32 inch hoses x 2 at one end and 1/4 hose x 1 at other end.

Often due to race car vibrations, the plastic ones break and can be difficult to find. These steel units won't break and can be cable tied safely to a fixed body. These are an excellent emergency back up spare if weight is an issue.

There is nothing worse than having the air valve release the rear rebound damping too early due to hose or fitting failure.

One required per pair of rear shocks.
