We may have an option that will work for you, but you will want to remeasure your axle as the length is measured from hub face to hub face and not between the tips of the spindles.
The closest option we have as a standard axle replacement would be the Dexter Trailer Axle w/ Idler Hubs - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # 35545I-EZ-89 for an axle with the idler hubs, or # 35545E-ST-89 for an axle with electric brakes. Both options have the 5 on 4-1/2" bolt pattern... view full answer...
