By using a lighter weight driveshaft, you reduce its rotational mass while it is turning, freeing up horsepower, which translates to faster speeds and lower ETs. These lightweight aluminum driveshafts are just the ticket. They feature high-strength, .114 in. wall thickness, a 6061-RT62 aluminum seamless tube, and include 1330 high performance U-joints. They weigh approximately half as much as your OEM steel shaft, but are twice as strong!
