Summary
This APEX Design USA service kit supplies replacement O-rings for the Steering Boost Kit. Seals are the wear item in any hydraulic hardware - renewing them keeps the boost system sealed and consistent instead of weeping its performance away, and having the kit on the shelf makes seal service a same-day job.
Best For
- Steering Boost Kit owners servicing seals on schedule
- Fixing a boost setup showing seepage or inconsistent feel
- Trip-prep servicing before long hauls
