One Nut Was Cross-Threaded

One hex nut started to bind—looked slightly damaged. Replaced with a spare, but should’ve been checked before packaging. Otherwise great.

Survived Rough Terrain with Ease

Running on a rocky quarry access road. After weeks of vibration, no loosening or fatigue. Zinc finish still looks new. Built for abuse.

B
Brose Arstingall
Strong Clamping Force, No Slippage

After torquing to 135 ft-lbs, zero movement under load. Axle stays centered. U-bolt length is perfect for double nuts.

R

Minor Misalignment of Tie Plate

Tie plate didn’t sit flush at first—had to adjust with a hammer. Once seated, clamping was solid. Design could be tighter.

C
Carlos Ramirez
Good Value for a Complete Kit

Compared local suppliers—this was cheaper and better packaged. Yellow zinc resists oxidation. Will buy again when upgrading the other axle.
