The Swiss Army of truck racks is now even better. Redesigned to save previous real estate in truck beds, the DriveShaft Track is better than ever before. 12mm, 15mm, 20mm thru-axle bike rack carrier for truck bed channels found in Toyota, Chevy, GMC, and Nissan. RockyMounts DriveShaft is the first on the market with the ability to carry 12/15/20mm 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.
