Made from durable materials, this shim resists wear and deformation under high temperatures and pressures. Accurate shimming helps prevent issues such as oil leakage, excessive wear, and loss of power. It also facilitates easier assembly and maintenance by allowing precise adjustments during engine rebuilds or repairs. Ensuring the correct fitment of this shim is vital for maintaining engine performance and preventing costly damage.
