Our Performance Shim Under Lifter Kit are great for racing!

Also know as a "Cam Follower Kit" or "Shim under bucket kit", this kit is designed to replace the factory cam followers and shims giving you a lighter, more reliable valve train without any problems at high RPM and with long duration/high lift cams. Our kit is the lightest on the market, it allows for best throttle response and very little stress on the valve train. This lightness also allows the lifters (followers) to follow the cams more closely with less pressure (meaning less wear); allowing you to rev to higher RPMs with less risk. This kit is a necessity for those with racing camshafts (greater than 292* duration) but also a great way to dramatically lighten the valve train on any S14. The cam followers and lash caps are both hardened for reliability and durability and are manufactured for VAC Motorsports with state of the art equipment to exact motorsports grade tolerances.

This kit includes:

• (16) Lightweight Solid Lifters
• (9)3mm (9)3.5mm Lash Caps. (can be ground down to achieve the proper valve lash if needed)

VAC Tech Tip:
This kit is required when using racing-spec camshafts (anything LARGER than Shrick 292°).
Acceptable for use on street or racing vehicles.
