05-06 (ONLY) GTO 3.5 Driveshaft 1000HP 1-Piece Shaft with Direct Fit Rear Flange
Product Description
Now with a direct fit rear flange, eliminates the billet aluminum adapter plate!!!!!
The 3.5" aluminum single piece driveshaft is a direct bolt-on system. Most driveshafts available for the GTO platform require the rear flange to removed from the diff, the problem with this is that the differential is a crush collar type, and the preload on the nut sets the pinion depth to make sure the rear gears have the proper engagement. What we have done is made a 7075-T6 aluminum conversion flange that will bolt directly to the 3 finger flange on the rear But now has Helicoils in the threaded section of the billet plate(same style we make for the 1000HP Supra shafts). This eliminates the need to have a professional set the pinion lash on the differential. Just unbolt the factory 2 piece shaft, install the 1-piece shaft with the included hardware and go. The only necessary modification is the tip of the rear seatbelt bolt that protrudes into the driveshaft tunnel must be ground down to provide adequate clearance for the driveshaft. Changing the shaft in this car is perhaps one of the most noticeable performance enhancements you can do as the car will have better throttle response and feel smoother overall. Not only is it lighter but the hanger bearing on the factory driveshaft moves up and down violently when the car is being driven hard. This action is not only dangerous but robs the drive train of power. Capable of 997lb of torque based on shock factor of 3.5 .

No more bad vibrations! Excellent upgrade.
Posted by Schultz on 27th Jan 2016
I had a lot of vibration in 1st and 2nd, as well as when letting off the gas at highway speed. Turned out that my center support bearing on the factory two-piece was about gone and I had a choice between replacing it or going with this one-piece through Kollar. I decided to order through Kollar because not only does he have excellent products and turn around times, but he knows a lot about what your GTO needs and will give you good advice along with superb customer service.
The new one piece eliminated all of my vibrations and gave the car a quicker and much smoother throttle response. This is one upgrade I would definitely recommend for your GTO, not just for the performance benefits, but simply to make your car safer on the road by getting rid of the ticking time bomb that the stock two-piece is. -

Excellent upgrade!
Posted by Brian Mc on 9th Sep 2015
So like most GTO owners I had lot's of noises coming from what I thought was the rear end. Finally tired of the racket I pulled the trigger on this drive shaft. Not only was shipping quick...3 day turnaround, but once installed most of the noises I had are gone. The feeling is immediate. The car feels more powerful, launches are more sure. You will feel the car and road more, but its a sports car!

This is one of the best upgrades you can do for your GTO. Whether you are stock or highly modified, your GTO will benefit from this driveshaft. Install is very easy also. Thanks Kollar Racing!
