This Lainer Suspension shock spacer is designed for WP rear shocks fitted to KTM and Husqvarna 85 models up to 2017. It is a -2 mm spacer intended to change the shock’s internal length/positioning as part of a suspension setup or rebuild. Use it when you are servicing the shock and need this specific spacer offset; do not fit it as a substitute for worn components unless a spacer change is actually required.
This is an internal shock spacer used within the WP shock assembly. It is typically installed during a shock rebuild or when altering internal configuration, rather than as an external adjustment. If your issue is oil leakage, inconsistent damping, or noisy operation, those symptoms usually point to service parts (seals, oil, bushings) rather than a spacer change.
A -2 mm spacer change affects internal geometry and should only be used when you are deliberately targeting that change for ride height/positioning or to match an existing shock build. If you do not have a clear setup requirement for a -2 mm offset, retain the original internal configuration and focus on standard service items.
Replace or fit an internal spacer when it is specified in your shock build plan, when correcting a previous incorrect assembly, or when the existing spacer is damaged or deformed. Do not replace spacers as routine wear items unless inspection confirms damage, as many shock performance issues are caused by fluid condition, seal wear, or incorrect assembly torque rather than spacer condition.
