This Lainer Suspension Racing high and low speed compression adjuster kit is designed for compatible Showa rear shock absorbers used on selected Honda CRF and Kawasaki KX-F models. It replaces the standard compression adjuster to provide a more usable adjustment range and finer sensitivity to changes, supporting more repeatable tuning for rider weight, terrain and riding style.

Why Choose Compression High and Low Speed Kit SHOWA CRF-KXF 2017-2021?

Compression damping control is split into low speed and high speed circuits, each influencing different parts of the shock’s response. This kit provides separate high and low speed adjustment at the external adjuster, which can make set-up changes more meaningful and easier to reproduce when you are chasing a balanced feel rather than guessing whether the stock adjuster “did anything”.
