Big Tire Tuning Guide
This tuning guide is intended for use with Reaper Suspension’s rear shocks for a 33x10.5 and larger slick tire application.
Shock Adjustment Basics
- All adjustments should be made from full tight (fully clockwise) on both compression (C) and rebound/extension (R). If your shock is equipped with a collar style adjuster for the rebound, full tight will also be fully clockwise.
- The compression adjuster will always be located on the compression head, while the rebound adjuster will always be located on the shaft of your shock. This is true no matter the orientation of your shock.
- Make shock adjustments in small increments (two or three clicks) per pass.
Baseline Settings (Starting/Reset Point)
- Compression: 10 clicks from full tight
- Rebound: 15 clicks from full tight
Track Condition Recommended Adjustments
| Track Condition | Compression | Rebound |
|---|---|---|
| Decent / Average Track | 10C | 15R |
| Hot / Greasy Track | 6C | 18R |
| Cool / Tight Track | 12–18C | 8R |
Tuning Notes
- More power? Tighten compression and rebound to control the hit.
- Less power / poor track? Loosen compression and rebound to soften the hit.
- Losing traction before 1 second? Loosen rebound to help the shock separate.
- Losing traction after 1 second? Tighten compression 2–3 clicks and loosen rebound 1–2 clicks.
