With the adjustable spring centers I would need to drill bolt holes for the mounts, correct?
1 answer-
ProductExpert30· 4 years ago
The sprint seats are to be welded on. You do not need to drill holes in the axle. There is a spring to help adjust the seating.

I just purchased this axle and I'm in the process of installing it, On my axle the fast lube grease fitting is not in the center of the axle shaft, does it matter which way the fitting should sit when on the trailer? Toward the top, bottom, left or right?
1 answer-
UltraTowExpert11· 3 years ago
The grease fitting can be installed in any position as long as it is accessible.

Do the saddles need to be welded to the axle ? And is there one available for 1 inch bearings?
1 answer-
UltraTowExpert11· 3 years ago
The spring mounts should not be welded. The spring mount will need to be bolted down through the bolt hole on the mount. We do not offer an option with 1 inch bearings.

will this work for a 54'' center for the leaf springs
1 answer-
UltraTowExpert29· 7 years ago
This axle is designed to have adjustable spring centers that range from 55" to 61". We cannot recommend adjusting the spring centers outside that range as it could cause damage to the product and would void the warranty.

Do you have a 16" wheel that would fit this axle?
1 answer-
UltraTowExpert11· 3 years ago
The axle is compatible with wheels that have either a 4-hole pattern on a 4" bolt circle or 5-hole pattern on a 4-1/2" bolt circle. The hub will need to be attached to the axle first and then the wheels would be mounted to the hub. The 4 bolt hub item number 57224 will work with the 16.5" tire/wheel assembly item number 12112.
