2004-2006 Pontiac GTO - Will also work on most Holden IRS cars For our Level 1 half shafts, we use super strong 930cv joints with hardened races and chromoly cages.
The axle shafts are made from billet 4340 steel. Rated to 800 RWHP
Comes with 12.9 grade installation bolts and loctite. Our half shaft assemblies come with our ultra cool black e-coat corrosion finish at no extra charge.

We have A4 customers running 10.20's and M6 customers running 11.00's on the Level 1's.
We even have at least one guy running 9.80's on Level 1's but we dont recommend running that fast on Level 1's. We recommend stepping up to Level 2's once you get into the 10's.
