How much wider does it make the front end when you install zero preload suspension? I'm looking at a-arms again and I was wondering is +2 arms with zero preload would make my raptor too wide.

 

It would make it wider by 4" but not too wide, the Raptor is kind of narrow stock.

ZPS shocks will lower the quad and make it handle better in the turns but they are really good if you are going to jump, you get th lower center of gravity (the shocks ride further compressed) but when the wheels are off the ground, the shocks extend "full length" so the hydraulic valve system has the full length of the shaft to slow down. It's a couple of softer springs on top of firmer springs and the soft springs are only there to extend the shock when the wheel is off the ground.

 

so the zero preload suspension alone would widen the front end by four inches?
