Put the FRA adjuster to stiff, loosen the big shock till you have 1 inch of thread showing, then loosen up the small front shock till it just holds up the spring, now compress the front arm of the skid(by placing a wood block of 4x6 ) under the front of the skid, set sled on top of block then tighten up the limiter straps till the W arm is about level to the ground.
now when you get this done and set the sled on a level floor the rear idlers will be off the ground, simply shim the BOTTOM of the transfer rods to bring the rear down,you add the shims to the bottomside by the 14mm headed bolt.
try to get the track sitting as flat as possible,you can fine tune it by the shims on bottom of rods and by adjusting the front limiter straps.
you can simply loosen up the front shock adjusters to lower the front, if you get it real low,be sure to take peice of duct tape and wrap around the very top of the shock/spring,so the little retainer wont come out if you happen to pick up the front end. you can also strap them down but its easier to just adj the springs in my opinion.
