Motorcycle Shock Spring Hydraulic Preload Adjusters

HPA - Hydraulic Preload Adjusters

When most riders talk performance the first thing they think of is power, but chassis setup and suspension are equally important. Start with a properly maintained bike: clean, no leaks, fresh oil and correct clutch setup. Fine tuning spring preload keeps the chassis at the right sag height so the damper has usable stroke. Where stock castellated rings are awkward to reach, hydraulic preload adjusters from TracTive and other quality makers give rapid, precise roadside adjustment without fighting with spanners. These kits use durable hydraulic internals and wide dial control to reduce bottoming and improve comfort when touring or changing loads.

Hydraulic preload adjusters for quick on-bike sag control

  • Tool-free, rapid preload changes for pillion or luggage
  • Improves sag height and reduces bottoming
  • Protects paint and avoids scratched preload collars
  • Simple DIY fit with a shock spring compressor

Recommended Pairings

Consider matching with Suspension Tools and view related guides on road bike setup or offroad setup. Use shock spring compressors here and consider mechanical preload options MPA rings.
