Ring, Piston, NOS Oil Control Set of 8, for 90~95 ZR-1 LT5.  Oil Control Rings ONLY, a set of 8 rings.

NOTE: This is a NEW, GM OEM part, manufactured by Mahle/Goetz for GM.

NOTE: GM OEM piston rings are no longer available from GM, or any other source to our knowledge. Inventory is very limited with no replacement possibility. There is an after market supplier producing rings represented to be for the LT5 engine but sources indicate the compression rings may be too small, resulting in excessive piston/ring side clearance and cross section width. The oil control ring furnished with these aftermarket sets are of the 3-piece design, whereas the OEM ring is a 2 piece ring, specified by GM & Lotus design engineers for the LT5 nikasil cylinder sleeve.

This set of 8 Oil Control Rings, are original NOS, not aftermarket.  Very limited quantities remain and cannot be replaced.
