QA1 JJ-11216 - Carbon fiber driveshaft for circle track applications. With a length of 38.50", a diameter of 2.25" with a 1310 U-joint. Includes an 8" slip yoke.

With a 2.25" diameter, and available in all popular lengths with U-joints and an optional slip yoke, QA1 carbon fiber driveshafts are lighter, stronger and safer than aluminum and steel driveshafts. QA1 specially winds the driveshafts with 3M Matrix Resin that is exclusive to QA1 driveshafts. 3M Matrix Resin uses spherical nanoscale silica that provides improved abrasion resistance and longevity, higher compressive strength and minimal water absorption for increased torque capacity and longevity. This resin is what gives a QA1 driveshaft its distinctive blue tint. The driveshafts have a uniform wall thickness created by optimum fiber lay up that ensures high RPM stability as well as extreme torque capacities. A thoroughly engineered surface protection is used to withstand extreme racing environments and provide a worry-free performance. These driveshafts also feature Spicer Life Series Universal Joints that are high strength alloy and provide durability, high torque capacity and are sealed for maximum stre
