Stop breaking rear ends!
-
- made to order, so allow three weeks for delivery
- includes top-of-the-line race industry Spicer rebuildable U-joints
- superior vibration dampening
- eliminates "harmonic whipping"
- enables higher RPM operation
- much safer than steel or aluminum driveshafts which can impale you through floorboard when they break (carbon fiber disintegrates into harmless ball of thread with no sharp edges to injure you)

POWERTRAIN INDUSTRIES HEAVY DUTY STEEL DRIVESHAFT
A stronger driveshaft will assure that every horse gets to your rear wheels
- uses top-of-the-line rebuildable Spicer U-joints
- Spicer U-joints are much beefier and more durable than non-rebuildable OEM U-joints (see comparison pics at left)
- driveshaft is balanced at the factory so you can bolt it right on
- comparison to stock
- NA8/NB8 shaft diameters:
- OEM = 60mm / PTI = 64mm
- NA8/NB8 shaft weights:
- OEM = 10 lbs. / PTI = 13.5 lbs.
- we haven't yet compared the NA6 shafts, but could, if requested
- Email us to get on our update list for carbon fiber driveshafts, which we're nearly ready to have for sale
