I have ruined 2 sets of 4" front springs @ the dunes. I can catch most banshees at the drags, but the WOT clutch dropping associated with a good launch is ruining springs. I currently am running a 6" spring in the front, But I am afraid of ruining my new driveline, so its not yet tested. Will the bigger arch help or hurt performance? Any steetable solutions? 4" springs were Tuff-Country, I tried 4"EZ-Ride and the 4"HD springs both turned into an S with just a handfull of luanches. I know rear paddle tires would help but they are spendy.
