Rear Shock Setup:Because it is highly likely the original rear shocks on older models are repaired/replaced/upgraded throughout the lifetime of the frame, we offer some very basic tuning guidelines, and recommend using the original rear shock manufacturers manual for more detailed set-up for the specific rear shock you have. Contact the rear shock manufacturer for info if you do not have it.
The key component for set-up with any rear shock here is sag. Once you have that set-up correctly, the rest of the shock settings are fine tuning adjustments (Rebound and Compression damping, etc.) set to rider preference.Recommended sag is 13-18mm at the shock shaft - This equates to approximately 15-25% of the total rear wheel travel. Less sag = a firmer suspension feel.
Rear Shock Notes:All versions of the Heckler.5 can run 7.875" x 2.0” shock or 7.875" x 2.25” - Both are compatible (2.0” = 125mm rear wheel travel - 2.25” = 143mm rear wheel travel )
