A compact, independent suspension solution for lightweight motorcycle pull-behind trailers, campers, and trike builds.
This R&P Carriages torsion half axle provides an efficient independent suspension system for light-duty towing. By utilizing internal rubber cords to absorb road shock, it eliminates the need for a traditional thru-axle beam. This design allows for superior ground clearance and a significantly smoother ride, protecting delicate cargo in small-scale builds like motorcycle cargo trailers or trike trailers.
Start Angle: The 45° down start angle provides the maximum ride height and ground clearance available for this series.
Hub Specifics: Equipped with a standard 5 on 4.5" bolt pattern, matching most Jeep and Ford-style small trailer wheels.
Application: Perfect for trailers where the total weight stays under 500 lbs (when used as a pair).
Independent Travel: Bumps encountered by one wheel are not transferred to the other side, ensuring a stable towing experience.
Dampens road vibrations using internal rubber cords for a progressive, smooth ride.
Ready to install with 5-lug hub, bearings, and seals already matched to the spindle.
4" x 4" plate with 3/4" bracket thickness and 3" center-to-center hole spacing.
An overall length of 14-1/2" makes this unit ideal for narrow or specialized trike frames.
