! NOTE: When softening the ski springs, also soften the rear to match entire suspension REAR ARM MOUNTING POSITION (Between Rails)
! CAUTION
If the ski shock spring is adjusted too loose, the spring retainer may fall outIf the spring is adjusted beyond specification, the spring will coil bind and spring adjuster damage will occur
There are several mounting holes found in the rails for installing the rear armThe holes have been added to the suspension to provide adjustment to fine-tune the suspension to driving stylesIf the ride is too soft, moving the rear arm back between the rails will stiffen the rideBy moving the rear arm forward, it will collapse quicker and allow more transfer of weight to the back of the suspensionThis will also affect the handling by providing softer ride and also easier steeringThe drawbacks of moving the rear arm forward are that the suspension may bottom out quicker and some travel is lost! NOTE: When making any changes to the front or rear suspension, the change should be made at both ends to keep the suspension balancedFor example, installing stiffer springs in front may require installing the next step stiffer spring in back to keep everything in balance
