This R&P Carriages custom 3,500 lb trailer axle is built for applications requiring a 57.75" hub face, 44.75" spring center spacing, underslung spring configuration, and 5 on 5-1/2" hubs. It is intended for buyers who need a measurement-specific axle rather than a standard off-the-shelf replacement.
Custom axle fitment depends on accurate measurements. Hub face, spring center spacing, spring orientation, and hub bolt pattern all need to match the trailer before production.
Compatibility: Built for trailer applications where the supplied hub face, spring center spacing, capacity, spring configuration, and wheel bolt pattern match.
Vehicle / System Fit: 3,500 lb trailer axle applications requiring a 57.75" hub face and 44.75" spring centers.
Installation Notes: Verify spring seat location, under-slung configuration, wheel bolt pattern, and any brake or hub requirements before installation.
Ordering Insight: Custom axles are measurement-specific. Once production begins, fitment depends on the accuracy of the supplied axle dimensions.
Built for the listed 3,500 lb trailer axle application and supplied dimensions.
Configured for trailer applications requiring a 57.75" hub face measurement.
Spring center spacing supplied as 44.75" for the specified trailer setup.
