Description

Product Overview

The DNJ Head Spacer Shim is a precision‑engineered component designed for the 2JZ‑GE 3.0L engine found in 1992‑2005 Lexus and Toyota models such as the GS300, IS300, SC300, and Supra. Constructed from lightweight yet robust aluminum alloy, the shim measures 0.020 inches in thickness and is intended for installation on the engine block side of the cylinder head. Its compact dimensions (15 x 12 x 2 inches) and low weight (13.3 ounces) make it easy to handle during installation.

Usage

This shim is ideal for both performance upgrades and routine maintenance. Install it when rebuilding the cylinder head, addressing valve train noise, or seeking a modest increase in compression ratio. It is suited for street‑driven vehicles, track days, and classic car restorations where maintaining factory tolerances is critical. The shim’s 0.020‑inch thickness provides a subtle yet effective adjustment, ensuring proper clearance without requiring major modifications.
