Probably not, I have driven around in 4 high for a while before.I actually had a 91 gmc I drove in 4 high for like 2 months because I broke the rear drive shaft. I still towed with it that way too.
What are you saying?? Mines not 500rwhp? Haha, it is actully 426 RWHP. Yeah, I thought about all the racers and realized prob. a dumb question. :toiletI have run mine in 4hi WOT, with over 500+ rwhp for 1/4 mile increments many times...still holding up.
