DO35 Compatible Weight Distribution Hitch (800lb/365kg) - 30 inch truncated spring bars (incl. cam washer)

Hayman Reese DO35-Compatible Weight Distribution System

Engineered for Off-Road Towing

This DO35-Compatible Weight Distribution System maximises DO35 coupling movement, offering up to 35° of downward articulation and up to 120° of side-to-side movement depending on A-frame design. With the spring bars removed, the coupling retains full off-road flexibility, making it ideal for technical tracks, uneven approaches, and low-speed manoeuvres. An integrated chain hook secures the safety chains and prevents them from dragging on rutted or uneven surfaces.

Durable Trunnion-Style Design

The trunnion-style spring bars suit both mid-mount and bottom-mount off-road drawbars, providing strong, dependable performance on harsh Australian roads. The welded head, cast shank, and reinforced brackets are built to handle dust, corrugations, and repeated articulation—ensuring longevity for extended towing and remote-area travel.

Restores Stability and Towing Confidence

By distributing ball weight effectively across the tow vehicle, the DO35-Compatible Weight Distribution System helps return the vehicle to a more natural, level attitude. This supports correct suspension and steering geometry, braking performance, and headlight aim. These improvements help reduce tyre wear and provide better control, especially when towing heavy off-road campers across long distances.

Simple Compatibility and Setup

Designed for DO35 couplings while remaining compatible with standard tow balls, this Weight Distribution System suits off-road caravans, camper trailers, and hybrids. Multiple drop shank sizes are available to match different 4WD ride heights. A convenient QR code on the packaging links directly to full fitting instructions for straightforward setup.
