1750lb Torsion Half Axle Right Passenger Side 22 Down 3500 lb Pair 5-4.5 Hubs
A heavy-duty independent suspension solution for trailers, campers, and utility dollies designed for superior ground clearance and customizable floor layouts.
Overview
This 1,750 lb torsion half-axle utilizes internal rubber cords to dampen road shock, eliminating the need for leaf springs and shackles. The 22° down starting angle sits the spindle lower than the axle tube, providing roughly 3-4 inches of extra frame lift compared to neutral axles—perfect for off-road builds or trailers requiring high ground clearance.
R&P Service Insight
Half axles are a "fabricator's favorite" because they allow for open-center trailer designs. However, precision during installation is key to tire longevity.
- Trailing Arm: Must be installed so the arm points toward the REAR of the trailer.
- Mounting: Ensure the trailer frame is reinforced; half axles concentrate torque on a smaller area than full axles.
- Ride Height: Expect the 22° down angle to level out toward 0° when the trailer is fully loaded.
R&P Knowledge Hub
Compatibility: Standard 5 on 4.5" bolt pattern fits most 13", 14", and 15" trailer wheels.
Suspension Style: Progressive rate rubber torsion provides a quieter, smoother ride than traditional leaf springs.
Installation Notes: This is the Passenger Side axle. It must be paired with the corresponding Driver Side unit to achieve a 3,500 lb GVWR.
Independent Travel: Since each side is independent, road bumps on one side will not affect the stability of the opposite wheel.
R&P Build Insight
Measuring for "Fit" is critical when using torsion half axles in custom projects.
- Stub Length: Verify the 24" length from the hub face to the tube end fits your frame width.
- Alignment: Use a string or laser to ensure the spindles are perfectly perpendicular to the trailer tongue to prevent tire scrub.
- Brake Ready: Includes a standard flange for 10" brake assemblies (Electric or Hydraulic).
Features
22° Down High Clearance
Optimized for off-road or high-profile trailers, providing 3-4 inches of additional lift over neutral axles.
Maintenance-Free Cords
Four natural rubber cords inside the tube provide the spring rate without any metal-on-metal wear points.
Integrated Brake Flange
Features a standard flange, making it easy to add 10" electric or hydraulic brakes.
Open Center Design
Eliminates the center axle beam, allowing for drop-floors, water tanks, or lower cargo storage areas.
