Show original supplier description
The Tomei Valve Lifter Shim is a high-strength, cold-forged component engineered for precise valve spring load adjustment in Nissan RB26DETT engines. This shim is intended for use with solid type camshafts and can be adjusted by using various shim thicknesses to accommodate different spring rates. The cold forging process ensures high durability and a lightweight design, weighing approximately 32g compared to the stock 33g. This particular shim is designed to suit TOMEI camshafts with up to 9.15mm of lift and is also compatible with NISSAN OEM camshafts. It is specifically designed for use with Tomei or OEM Nissan RB26 lifter shims and fits engines from 1989-2002 Nissan Skyline GT-R models (R32, R33, R34). It's important to note that this product is not compatible with NEO 6 engines.
