Default GForce 1320 axle kit

Install was straight forward. I've never taken apart a half shaft before, wasn't bad at all. Just make sure you have a fresh roll of shop towels when you do it.

As far as rear end parts my car has poly diff bushing, poly diff block, and bushings. The cradle bushings tightened the rear up a good amount, but not a hop aid really.

This passenger side axle kit has gotten rid of 99% of my hop. Brake stands, zero hop, dead stop or roll clutch drops, zero hop. The only time I can feel it hop is from a 2k 1st gear hit, and it's VERY minor.

Icant wait to get this KARS III kit on. Hello 1.8 60's!!!!

you wont need a new diff, since you have a gen 4...but at a prepped strip, you will hook better. And therefor you may hop slightly more then you will on the street.

and that will lead to one of 2 things:

#1, Good run through the 1/4...yay
#2, Snap goes a CV (or something else)...boo

Because you will break something if you do brake stands or clutch drops in a V1.

So is it the same result if I shift into 2nd while doing a brake stand and feather the gas between 4-6k and there's still no hop?

Blown diff, got it!

I hoped at the track in 3rd gear really bad. I was fine off the line the track was a little slick down track.

Hey guys, alongside the anti hop axle kits (whether it be gforce or hendrix) what else would be a good upgrade for the rear end? i have an 06 with the better diff, and planned to get the axle kit ASAP but if there is anything else you guys would suggest while doing the axle swap, then i mine aswell get it to save me in the long run.

My question is... how many instances do we have where individuals have broken their rears with the axles?
