i don't reply on here much, but i read a lot. As far as wheel hop goes, don't count out your shocks. Shocks control the balance of vertical movement as well as traction and acceleration. I've been part of Racing Teams, from Sprint cars to Road Racing and bad valving on a shock will cause a lot of things, wheel-hop is one of them.

Even if you have brand new FG 2's or FE 4's, the valving in these shocks may not hold up to Extreme Shaft movement. (insert perv joke). Braking the tires loose such as burnouts can overload a OEM shocks even hard acceleration may cause Stock OEM valving to get overloaded. Paired with an aftermarket lowering spring with Higher spring rates will only make this more frequent. You should always match a heavier Spring rate with more shock valving.

The Stock factory CTS-V suspension has always been an issue. Adding one piece such as upgraded axles is a good step, But i would followed up by adding/upgrading the rest of the components.


Just a suggestion, may not be the answer.

Interesting info above.

Does anyone with (adjustable) coilover experience have any input?

I dnt care if u have a solid rear or independant rear, u dont ever (or you shouldnt) do burnouts on rough pavement.

Only time you should upgrade 1 axle is if u have an 06-07 V since they already have the updated or improved axle.

^ ive heard people having better improvements with both axles for 06-07's

I have ksport coilovers set at a softer setting. No difference noticed
On 04 05 it the pass side that should be changed

Now that I think of it, I do have a 4th gen diff. Should I have changed the drivers side even though the car is an 05 ??

I have rebound adjustable QA1's and tried different setting (side to side) and didn't help with stock axles or with the driver side Hendrix axle. The Hendrix axle stopped the hop up to about 3000 rpm. I installed both Gforce axles and the hop is gone up to 5500 rpm. I'll be installing the DSS 1000 Hp axles soon because I keep exploding passenger side CV's. I have even twisted the stub shaft off inside the diff carrier once.


The diff doesn't matter, the axle shaft diameters were changed in '06.

I had an 05, hendrix drivers side axle only.....and I had ZERO wheelhop on the street, only at the track.

I'm amazed how many folks are breaking axles, seems crazy to me. I wanted a new DDS single (econo) axle but now I am rethinking that decision.

04-05 have both small diameter axles. 06-07 have both large diameter axles.

FYI - Swapping an '04-05 axle into an '06-07 (or vice versa) doesn't help.

I had the Hendrix "pro" axles with the race CVs. They reduced wheelhop. On the street. They did NOT eliminate it. On a prepped track, they didn't make a bit of difference. This was with FG2 and all season tires. Don't waste your money on the "pro" axles. They don't do any better than the "economy" axle.

I realize that this thread is 2 years old, but reading on it i noticed some people have been saying something about different sized axle shafts. I bought a pair of G-force axles this weekend, but they dont say anything about "Gforce" on them, and they are two different sized axles??

Is this how its supposed to be?

all I can say, is if you think that a little harmonics change is going to fix wheel hop... you have been duped by advertising...

Wheel hop is not caused by axles and cannot be fixed with axles

wheel hop problems need to be solved with suspension changes

I've actually got all revshift bushings for the rear as well. I just figured i'd upgrade my shafts while i was upgrading the bushings.

Yes, having different size axles (or asymmetric setup) is the whole idea. It is designed to prevent the dynamics that trigger the wheel-hop.

The GM engineers that came up with the asymmetric axles for the V-2 apparently disagree. In my case the Hendrix axles completely eliminated the wheel open though others have had varying degrees of success.

Awesome! i think what has been throwing me off is the fact that my axles are already assembled. I've been trying to find a good write up on the installation of the bushings and/or the axles but havent had much luck.

The write ups i've seen talk about having to seperate the oem inner and outer and putting them on the g-force pieces. I've finally figured out that mine already have the inners and outers on them.

I have run just one hendrix axle, both hendrix axles, and both geforce axles. For me, the hendrix axles worked great, with just one and with both, really got rid of the hop. With the geforce axles, I couldn't tell you the difference in stock and these... (although I think the build quality is higher than the hendrix axles. (note i still have the geforces installed and sold off the hendrix axles because i was tired of swapping axles...)

I think it can be very car dependent, I am hoping to get the revshift cradle bushings in soon and see if that helps more.

Blake's TT 05 with an 8.8 and the G-Force ales has no wheelhop whatsoever.......
