The Michigan Motorsports LS/LT Camshaft Thrust Retainer Plate Kit (Non-Countersunk) is a high-quality replacement solution for Gen III & IV non-VVT LS-based engines. This kit includes a flat, non-countersunk cam plate and the ARP Cam Retainer Bolt Kit (134-1002), making it a durable and reliable upgrade compared to the later factory countersunk torx-style plates and bolts that are prone to stripping. Designed exclusively for non-VVT engines, this kit ensures proper clearance and secure camshaft retention, making it an essential component for LS rebuilds and performance upgrades.

- Includes flat (non-countersunk) cam plate and ARP Cam Retainer Bolt Kit 134-1002
 - Direct replacement for GM #12589016
 - Prevents issues with stripping found on factory countersunk torx bolts
