Rocky Mounts Drive Shaft SD Thru Axle Mount

The Rocky Mounts DriveShaft SD is a 15mm and 20mm thru axle bike rack carrier for truck bed channels found in Toyota, Chevy, GMC, and Nissan. The RockyMounts DriveShaft is the first on the market with the ability to carry both 15mm and 20mm thru axles and to securely lock your bike.

The mouth opens wide for easy loading and the cam lever adjusts like a quick release for a strong hold. Snap-in nylon shims prevent the axle from being unscrewed and allows you to switch between 15mm and 20mm loads. The DriveShaft SD also comes with a dummy axle 9mm quick release to fit standard bike axles. Includes a lock and two matching keys.
