The "Critical Link"™
Carbon Fiber Racing Driveshaft
The technical advances achieved over the years allows us
to bring you the finest Racing and Replacement driveshafts available.
The PST "Critical Link" is a continuous filiment wound tube, allowing
Power to be transmitted from fiber to fiber to bring the following
advantages...
The finest driveshaft available anywhere.
Each driveshaft is specifically designed by our Engineering Department
to optimize the characteristics of Carbon Fiber required in your special
application.
Our newest "Critical Link" Carbon Fiber
Driveshaft for Drag Racing application is 3 3/4" diameter, a 50"
driveshaft weighs only 6LBS - with 1350 series solid U-Joints add 3LBS
and Slip Yoke add approx 2 1/2LBS.
All tube yokes are built from forgings
specifically designed by PST for our carbon fiber applications. This
carbon fiber driveshaft is a perfect answer to long, high RPM
applications such as Pro-Stock Trucks and can be engineered for any
amount of Horse Power. Years of use by many Pro Stock and Pro Mod teams
have demonstrated the reliability of our carbon driveshafts. Many racers
experience a half a tenth increase in performance just by going with a
carbon fiber driveshaft.
All custom driveshafts are designed for your specific application.
Advantages of Carbon Fiber
- Lighter than steel or aluminum.
- Three times torsional strength of steel.
- Torsional spring rate allows better tire hook-up.
- Torsional spring rate allows smoother shifting.
- Less shock load to the differential.
- Eliminates or dampens high speed vibrations.
- Reduces transmission and differential breakage.
- Characteristics can be varied by changing the wind, angles or diameter.
PST offers both steel and 7075 Billet Aluminum yokes.
- In drag racing applications - a better 60 Ft. time.
- ET's have been lowered in some cases by as much as .120.
- In stock car racing better control out of corners is
the result of the torsional spring rate.
- In road racing smoother shifting and better
durability of transmission and differential have been reported.
- Tested on Cobra's at 180 MPH on Dyno with no vibrations.
- A much greater safety factor - carbon fiber will
return to a fiber and not create shrapnel under the car, as would
aluminum or steel shafts.
