4" Aluminum 7075 Signature Series Driveshaft (1350 Ujoint)

Mark Williams Signature Series Aluminum Driveshafts are revered as the strongest and most durable on the market. Each driveshaft is custom built to length an specifications. These driveshafts are precision built, assembled, and balanced using in house machined components with a patented bonding process. Driveshaft meets SFI 43.1 specifications.

Mark Williams signature series aluminum driveshaft has a torsional strength at bonded joints and tubing that are higher than the U joints connecting the driveshaft for ultimate strength and reliability

Every shaft is electronically high speed balanced considering your maximum RPM requirements, with the transmission yoke to ensure vibration-free operation.

Note: A transmission slip yoke is required for balancing (not included in the price). We recommend purchasing or using a Mark Williams yoke with all of our driveshafts for best results. Driveshaft production cannot begin without measurements provided and signed off, and a yoke to balance.

Why accubond vs welding?

Mark Williams Signature Series aluminum driveshafts utilize a patented bonding process that creates a stronger joint than a welded joint, and avoids the issues caused by welding aluminum that can create failure points. Bonded driveshafts are superior to welded driveshafts when strength, durability, and quality matter.
