Key Features

• Genuine OEM Hydraulic Braking Integrity — Factory-sourced construction ensures the hydraulic freewheel brake circuit meets the original pressure and engagement specifications critical for safe trailer towing.
• Direct-Fit Axle Assembly — Engineered to mount exactly as the original, with matching bolt patterns and hub geometry for a straightforward swap on ST3500 and TRLR100XF trailers.
• Confirmed Fitment for ST3500 and TRLR100XF — Verified compatibility with both the ST3500 and TRLR100XF models, eliminating uncertainty when sourcing a structural trailer component.
• Freewheel Function Preserved — The integrated hydraulic freewheel mechanism allows the axle to disengage correctly during braking events, protecting drivetrain components and maintaining trailer stability.
• Braking Safety Compliance — A correctly functioning hydraulic brake axle is essential for legal towing compliance and operator safety — using a genuine OEM unit ensures the system performs as the trailer was originally rated and certified.

The axle assembly is the structural and functional backbone of a trailer, carrying the full load of the equipment being towed while transferring braking force to the wheels. On the ST3500 and TRLR100XF, the hydraulic freewheel brake integrates directly into the axle, using hydraulic surge pressure to actuate the brakes automatically when the tow vehicle decelerates. When this assembly wears, corrodes, or sustains damage, braking response becomes inconsistent or fails entirely — creating a serious safety hazard and potential regulatory non-compliance during transport.
