Overview
This complete 2,000 lb trailer axle kit is built around a 64-inch hub-face straight axle with a 1.75-inch round tube. It includes 5 on 4.5 idler hubs, 25.25-inch eye-to-eye leaf springs, and a U-bolt mounting kit. It is intended for compatible small utility trailers, ATV trailers, light campers, and similar light-duty applications where all measurements and ratings match.
R&P Service Insight
Axle capacity alone does not establish fitment. Measure the existing trailer before ordering and compare the entire axle and suspension configuration.
- Measure hub face: Measure from the wheel-mounting surface of one hub to the wheel-mounting surface of the opposite hub.
- Confirm wheel pattern: Your trailer wheels must use the same 5 on 4.5-inch bolt pattern.
- Check spring placement: Confirm the trailer’s required spring-center spacing before mounting the axle.
R&P Knowledge Hub
Hub Face: The 64-inch hub-face measurement determines the distance between the wheel-mounting surfaces. This measurement directly affects trailer wheel track and fender clearance.
Bolt Pattern: The included idler hubs use a 5 on 4.5-inch bolt circle. Confirm the bolt pattern on the trailer wheels rather than relying only on the number of wheel studs.
Spring Measurement: The supplied leaf springs measure 25.25 inches from eye center to eye center. Spring length does not replace the need to verify hanger and spring-center placement.
Capacity: The axle is rated for 2,000 lb. The trailer’s usable capacity remains limited by its lowest-rated axle, suspension, tires, wheels, frame, coupler, or other structural component.
Brand & Fitment Note
Selling Configuration: This listing is for an R&P Carriages complete axle package assembled around the specifications shown in this listing.
Wheel Application: Vehicle or wheel references do not guarantee trailer fitment. Use the stated 5 on 4.5-inch bolt pattern and applicable wheel specifications to confirm compatibility.
Before Ordering: Verify the 2,000 lb rating, 64-inch hub face, axle tube size, wheel bolt pattern, spring length, required spring centers, tire clearance, and mounting configuration.
