The Lainer Suspension compression kit is designed for WP 4CS fork systems and is supplied as a pair for both fork legs. It’s intended for servicing or upgrade work where improved compression damping behaviour and oil flow are required. Use it to support a more controlled and consistent front-end feel across varying conditions.

Inside the System

This kit targets the compression side of a WP 4CS fork, focusing on how damping oil is managed under bump and braking loads. Supplied as a pair, it’s intended to keep both fork legs matched when upgrading or rebuilding.

Compatibility

  • Designed for WP 4CS fork systems
  • Supplied as a pair (for both fork legs)

Key Features

  • Compression upgrade kit for WP 4CS forks
  • Developed to refine compression damping characteristics and oil flow
  • Intended to improve damping control and consistency
  • Suitable for performance upgrades and rebuild applications

Adjustment & Setup

This product is a component kit rather than an external adjuster. Any final feel will depend on overall fork condition, oil, and existing internal settings; follow your workshop process for assembly and setup during service.

Setup & Workshop Notes

Replace or install this kit when carrying out a fork rebuild or when addressing inconsistent or poorly controlled compression behaviour in a WP 4CS system. It may not be necessary if the fork is already operating consistently and meeting your current setup goals. As with any internal fork work, installation is best handled during scheduled servicing to ensure correct assembly and balanced left/right operation.
