Trailer Axles & Running Gear

Idler and braked axle programs with leaf-spring or torsion suspension and matched running gear.

PROGRAM OVERVIEW

Source trailer axles and running gear against the whole specification.

An axle quote is only comparable when capacity, track, hub face, spring center, spindle, hub, brakes, bolt pattern, camber, suspension, and documentation match. We normalize those variables before presenting an alternative.

Utility and landscape trailers

Cargo, RV, and marine trailers

Equipment, dump, and gooseneck trailers

Specialty and low-volume vehicle platforms

CONFIGURATION

What we define before we quote.

A useful alternative must match the critical interfaces and performance requirements. These are the normal starting points for this category.

Axle type

Straight or drop; idler or braked; tube and spindle sized to the approved rating

Suspension

Leaf-spring, equalized tandem, or rubber torsion configurations

Interfaces

Hub face, spring center, bolt pattern, brake size, bearings, seals, and wheel compatibility

Program scope

Axle-only or matched hubs, brakes, suspension, and installation hardware

QUALITY PLAN

What we verify.

Dimensional fixture check for hub face and spring center
Weld, runout, camber, and coating inspection
Brake, bearing, seal, and fastener verification
Capacity label and production traceability review

FAQ

Common questions on this category.

What axle capacities can you source?

We quote common light- through heavy-duty trailer capacities, including custom dimensional programs. Capacity is confirmed from the complete approved configuration, not inferred from tube size alone.

Does FMVSS 121 apply to every trailer axle?

No. FMVSS 121 addresses air-brake systems on covered vehicles; many light trailer programs use electric brakes and involve different requirements. The vehicle manufacturer must identify the standards that apply to its configuration.
