Heavy duty, good quality...probably a bit on the expensive side.

I was afraid to pull my 24 ft. Pontoon boat with a 115 motor on my single axle Wesco boat trailer. So, I found a second axle, and needed a set of u bolts to mount the system to the trailer. I slid the original axle forward and mounted the second axle behind it. The U bolts enabled me to mount the axle and now I feel very safe pulling the boat with dual axles
