So, is the wheel hop issue fixed?

I was under the impression that wheel hop will occur if there is not enough weight in the rear
(example: 1980's trend of jacking up the rear with air shocks).

Old school traction bars finally fixed the problem. BTW wheel hop started after installing a powertrax locker.

That's interesting.
When I swapped the stock 305 to a built 350 my setup was:
Stock th350 trans with TCI 10" convertor
3.73 posi
stock rear suspension: HD rear springs, Monroe shocks, stock control arms (un-modified) that's it.

The car ran 13.77 with street tires (no drag radials, they weren't invented yet), no wheel hop, just a clean burn out.

I wonder if a worn control arm bushing could have caused the wheel hop.

Nope. It had (has) all new fabricated control arms. The uppers are adjustable and have a helm joint in the front. I tried two different sets of springs, three different sets of shocks, added frame supoorts, and changed the tires (twice). Nothing short of the traction bars worked.

Yes, worn control arm.bushings can cause.wheel hop. Stance also has a big effect on it.

The bars as well as the tires work too well. I used to be able to do a decent "hoppy" burnout. Not I get very little wheelspin, and very minimal hopping.

So you're saying its time to go to the track?

I am just surprised that you went through all this to fix the wheel hop.

by dynchel Tue Jun 16, 2015 10:21 am

Me too. I went through every solution I could find. No hop bars came highly rated, but they don't make them for '73 '77's.

I believe DickMillerRacing has no hop bars for our cars.

I have an old DickMillerRacing catalog and price guide.

When I get home I will check. I remember the catalog lists the No Hop Bars separate from the kits.

And I believe there was only one No Hop Bar used for all the applications in his catalog. If I remember correctly, then the Lakewood and QA1 no hop bars should work.

I will get back later today.

The 15 year old DickMillerRacing catalog lists 2 No Hop Bars; 10 bolt & 12 bolt rear ends.

I do not believe Lakewood, Edelbrock, and QA1 specify rear ends.

I have the D. Miller Setup on my '71 Monte and my '70 Chevelle. There is a specific set for the Gen3 8.5 rear by D. Miller. Lakewood and QA1 do not have a set for the G3 cars.

You must use the D. Miller adjustable uppers with the DM No-hops to get the pinion angle back where it needs to be AND for the proper pre-load on the right upper. Mr. Miller will not sell just the no-hops, as in he "won't physically ship them to you".

The setup is quality A1 and worth the extra $$. the no-hops have 2 (two) mounting holes for the upper arms and in most cases the lower one should be used. for lower torque cars the upper hole could be used, but for 400 ft lbs or more, it will be too violent and will introduce too much "anti-squat" and cause a loss of traction and waste of energy.

there is a reason Moser raises the upper ears on their 12 bolts about 1.5" and not 3" like the one size does not fit all design of the Lakewood, and the formerly Edelbrock now known as QA-1's.

I did try all of these parts at one time or another.

I have a video that shows stock versus no-hops on an 11.7x pass in my '71 monte from the early 2000's.

I actually ended up using the relocation brackets as traction bar mounts.

Mine was on the verge of hop, just had kind of a slow oscillation going on at launch. This cured it.

I like that bracket. Does it just have one bolt to the cross member? Are the arms adjustable for length? Who makes them or are they homemade? Thanks

by 77cruiser Wed Aug 12, 2015 11:30 am

One bolt through the bottom & the top bolt is in the original hole. I made the arms, those are 1/2 heims.

by Joe73 Wed Aug 12, 2015 12:48 pm

I like it. Great job. I like the idea of lowering the arms on the frame side as opposed to raising the arms on the diff side.
