Carry-On Trailer Idler Axle, 3,500 lb. Capacity is rated 3.0 out of 5 by 8.
Rated 4 out of 5 by from Good product The axle is handling whatever I throw at it. The Reason for the 4 stars is the measurement for spring center is not right on. When i installed my axle the spring center on the axle was 60 3/4 inches. That was ok because I was replacing the hangers on my trailer.

Rated 5 out of 5 by from Pontoon Boat Trailer I bought this axle for my Pontoon Boat Trailer and it fit perfectly. I have a Performer galvanized trailer with a 20 ft Pontoon Boat. The axle was ready available at Tractor Supply and installation was simple. I'm happy with this product.

Rated 1 out of 5 by from Check Hanger placement before you buy So it's not 58". it's 58 1/2" and the hangers aren't even welded from center. one side sticks out further then the other because of poorly placed brackets.

Will this axle fit a 5x8 trailer if not what will

Asked by: Mikool85
The axle is measured by the hub face to hub face and then the spring seat spacing. This axle should work as the spring seat spacing is 58.5" which that is what ours is on our 5x8g trailers.
