this is how my sled is set up
1. took out one large shim from secondary
2. front shock preload 3 inches from retainer to cap, so basically leave three inches of shock showing
3. rear front torq arm- limiter in middle hole- back shock preload off to one turn from having no pressure at all
4. rear springs lighest setting
5. rear blocks set in the #2 setting (2 facing front of sled)
When the trais get rough set rear springs to medium setting. I wasn't happy with my f7 until i did the changes 100% better. The adjustments to the rear front shock and limiter straps made the most difference. do a little at a time so you can feel the differences, and have fun some minor changes make this sled reall6y rail.
