REAR SUSPENSION ADJUSTMENT
The rear suspension can be adjusted in three places
1- Adjustment of the spring preload
2- Adjustment of the softness drawbar (coupling)
3- Adjustment of the limiter strap
Spring tension
Loosen the jam nut (No. 1).
Using the special tool (No. 3), turn the spring preload adjustment
collar (No. 2), screwing it in to stiffen the spring and unscrewing
it to make the spring softer.
When the adjustment is finished, tighten the lock ring once
more. (No. 1)
1. Jam nut
2. Spring adjustment ring
3. Special tool
The adjustment of the spring makes it possible to stiffen the
suspension if it reaches the limit of its displacement and to make
it feel softer if the driver is the one absorbing the shocks instead
of the suspension.
Softness drawbar
With the 18 mm ratcheting box-end wrench from the tool kit:
Screw in the nut: This puts more pressure on the front of the
slide rail, which means the vehicle reacts more rapidly in turns.
(Short wheelbase) This adjustment will also increase the front
to rear coupling of the skidframe, which will in turn reduce the
amount of kick back in moderately rough terrain.
Unscrew the nut: This puts less pressure on the front rail, which
means the vehicle is more stable. (Long wheelbase) Reduces
front to rear coupling.
