Wheel hop with BBK control arms

[94Zman]

Just installed, bushings are good, hit it off the line in the rain and it got wheel hop? Should be an easy spin.... any ideas appreciared.

Thx

Do the BBK's have SOLID urethane bushings? Do you still have your quad shocks?

 

[94Zman]

Fox Saleen 163, no quad shocks are on, the bushings are the polyurathane type.

Thx

Quad shocks dampen axle windup, axle windup causes wheel hop. Maybe the lower control arms added more traction, which caused more axle windup. But, from everything I've read, soild polyurethane bushings in the lower control arm is a bad thing and causes deflection and suspension bind.

Thanks Fox Saleen 163, Guess its easy enough to put the quad shocks back it. Might try a looser setting for the comp engineering 50/50 shocks too. Also wondering if the pinion angle changed, its a 79 which came with a 7.5 rear and now has an 8.8 with 3:73's. The arms we a tight fit going in as well....

I have BBK lowers, boxed stock uppers with urethane on one end (Steeda style), & new Steeda quads (like $25/pr) & absolutely no wheel hop on street tires or slicks. Before this it was like driving over railroad tracks when I hit the gas.

Interesting, thanks I'll through in a set of quad shocks, that has to be it. Didn't come with these back in 79....

 

[94Zman]

Well, the quad shocks are in, still geting the same wheel hop. Any ideas?


Thx!

Did you just say you hit it in the"RAIN"...Why don't you try it when it's dry out and see what happens

 

[PURESTREET5006]

also you might wanna go to 70/30 on those rear shocks..do you have 90/10 up front or stock.

 

[Fox Saleen 163]

How old are you actual rear shocks? And what kind of springs are you running?

 

[94Zman]

Yeah, lately it only rains here, no change to nail it in the dry. Good idea to adjust to a 70/30 setting, thanks. They are new Comp Engineering adjustable ones, springs are the stockers. Up front are 70/30 Lakewoods and stock springs. Will also try some better quad shocks like a set of Gabriels. Hope that works....

Only other thing I can think of is the pinion angle out of wack, is there a way to check this and adjust, or do I need adjustable uppers?

Thx guys & Happy New year!

I'm pretty sure the BBK's come with urethane bushings on one end and normal on the other (for the upper's I believe) so there should be any binding.
