Cap, Valve Spring, for 93~95 ZR-1 LT5. Set of 32. One(1) Set of 32 caps / retainers are required per engine.

We measured over 1,500 retainers with a 10mm ball & micrometer to sort the valve spring caps into sets that are matched to within 0.003".  Knowing all of the caps are matched will help greatly in setting the installed valve spring height. 

NOTE: These are USED, GM OEM parts.
