I know there was some interest in these on the board, and we have a thread about it in one of the forums right now. So, if anyone is interested.

I just hung up with ACPT. If we can GP 5+ of these, they will be $200 off of the regular $795 and $40 freight (48 states of the US only). Meaning, $595 each (plus shipping).

The tech info is this:

Aluminum yokes.
800 ft lbs torque rating
3 1/4" OD
12,500 RPM critical speed

For an additional $100 you can have (and I know you guys will love this one).....

3 3/4 OD
2000 ft lbs torque rating
14,500 RPM critical speed


Anyone interested?

I currently own two different ACPT CF driveshafts on two different vehicles of mine- They are both daily drivers and the lightweight driveshafts made a remarkable difference in high speed smoothness AND (not a huge difference- but) a noticible difference in acceleration, and mostly a big noticcible difference in RPM's attained. It upped my shift rpms by about 300-500 rpms in each lower gear because of increased spinup speed and lack of vibration (on both vehicles).

As for any question of durability? One of these is in my daily personal work truck (lowered and built 89 Chev c1500 longbed) which happens to be 6 feet long X 4" dia with 1350 joints (the shaft with the yoke weights 7.8 lbs- the steel one was 28 lbs). This truck puts down a modest 340 hp and has a severely built 700r4 (5 planteries, the works- thump your head on the rear window every time it shifts, as well as a Currie 9" rearend with a Detriot Locker. I have the frame completely weled up on this truck and it can haul 4000lbs in the bed and weekly has an average 3000lb load in it for a delivery(last week was 3670). IPoint of this info is I beat the living crap out of this truck daily. This truck also does 140 mph and has been rumored to touch that weekly also although that can just be construde for legal purposes as an internet boast.

These CF driveshafts are strong and light- and will hold up
(ps- the 6 foot 1350 truck shaft cost me $1200 to have custom made (no shipping- I am local to them) Well worth it though considering I was breaking tailshaft yokes with the old steel unit every 6 months due to bad vibrations at critical speeds -had it rebalanced 3 diffenrent times by different shops and everyone said nothing else they could do- it was just too long and too heavy and was suffereing from critical speed vibration.
