I may be wrong but I think you should double check it with it at ride height to see if it changes too much one way or the other.
It was on stands with the suspension loaded. The trick was getting it level front to back with the rake I have going haha.

Re: Wheel hop issues, looking to learn...

My car sits pretty high and I have zero wheel hop. I boxed my lower rear control arms. My understanding was always that wheel hop was mainly caused by flexing of the rear lower control arms. They bend under acceleration and then the hop is caused by the controls arms straightening themselves out. Boxing them in eliminates the flexing.

I thought the same thing, but there's lots of suggestions on the internet. That's why I always come back here because you guys have the best advice for Chevelles. I've replaced all the rear stock suspension - new uppers/lowers, springs, shocks, bushings. The uppers are adjustable and the lowers are square channel boxed. Both have pivot joints at the front. These parts made little to no impact on the wheel hop. Next step is no-hops I guess. They're easy enough to install. If this doesn't work I guess I just don't do burnouts, because I'm not interested in lowering the stance - at this point :-)

I have Lakewood No Hop Bars in conjunction with Hotchkis controls arms. I get zero wheel hop when, as you say, I “light em up”.

Re: Wheel hop issues, looking to learn...

With the rear raised the upper control arms are pointing up towards the front. When you apply torque it pulls the car down & the rear up just the opposite of what you want. Good recipe for hop. The no hops should do the job.

Re: Wheel hop issues, looking to learn...

My 65 Chevelle sits a little tall cos when I built it I wanted to do it Old School!! Everyone was telling me to drop the front end a few inches but I refused to listen to them. I guess I did it right cos If I can get the video to play you can see for yourself. I think an hour trying to get it to post is long enough it keeps telling me invalid file!!

Air bags slightly inflated will work for you.

Try again after you have more than ten posts.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

BIGOT is a word used by people that can't use logical reasoning to prove that you are wrong when you don't agree with them.

Re: Wheel hop issues, looking to learn...

Here's my no-hop bars. I took the rear end out to install, much easier. I also installed poly bushings and UMI adjustable uppers. Replaced the brake lines while I was there. The original lower arms are boxed and new rubber bushings installed. 1" UMI rear sway bar. But, I still have a little wheel hop, I guess the next thing is UMI lowers with poly bushings. mine sits up a little higher than original also.

Looks great! The rear came out the first time last fall to do the gear swap, no idea why I didn't just do all this then. So it came out a second time this year to replace all the suspension components, u-joint, bushings, etc. I HOPING I can just drop the rear low enough to remove the upper bushings/install the no-hops w/o taking it out a third time. A lift would be nice, but what fun is it w/o a challenge. I am getting more efficient each time though ;-)

Re: Wheel hop issues, looking to learn...

Hey guys, small update. Got the no-hops from TA Performance Monday night. Hoping to tear into it tonight, we'll see how far I get. Wish me luck!
