INJORA Hitch Mount Trailer for TRX4M — Dual-Axle Metal Scale Trailer with Durable Steel Body

INJORA's Metal Hitch Mount Trailer for TRX4M is a steel-bodied, dual-axle scale trailer designed to attach to TRX4M bumpers and carry accessories or tow model rigs at events.

This compact metal trailer is built for RC rock crawler enthusiasts who want a realistic, durable towing accessory for the TRX4M platform. Hand-formed metal tubing and nylon-mold wheels give it a convincing scale appearance while providing robustness for regular use. It integrates with INJORA's bumper hitch system and offers a satisfying installation experience for hobbyists who like to customize their rigs.

How durable is this trailer for regular hobby use?

The trailer uses a handmade metal tube frame that resists deformation from bumps and knocks during transport. Nylon-mould wheels are chosen to withstand impacts and avoid easy damage compared with brittle plastics. Dual axles distribute weight better, lowering stress on individual components.

• Hand-formed metal tubing resists bending.
• Nylon-mould wheels reduce chip and crack risk.
• Dual-axle layout increases load stability.
• Robust construction suits event towing and display.

Will it fit my TRX4M and what installation steps are needed?

This trailer is compatible with bumpers that accept the trailer hitch #9796 and is optimized for INJORA's TRX4M bumper. When using the INJORA TRX4M bumper, you will need to remove the bumper's brass ball and replace it with a screw to accept the hitch. The mounting process is straightforward and designed to provide a satisfying hands-on upgrade.

• Compatible with bumper-installed trailer hitch #9796.
• Swap the brass ball on INJORA TRX4M bumpers for a screw.
• Simple bolt-on installation for hobbyists.
• Clear fitment for TRX4M platforms when using matching bumper.

What can I carry with this trailer and how stable is it while towing?

The dual-axle design increases towing capacity compared with single-axle scale trailers, letting you transport small accessories, scale gear, or even tow another scale rig short distances. The low-slung frame and balanced axles help maintain stability over mild terrain and during event maneuvers.

• Suitable for scale tools, recovery gear, and small cargo.
• Dual axles improve load distribution and handling.
• Best used for show towing and light-duty transport.
• Not intended for heavy real-world loads—scale use only.

What finish and detailing can I expect on the trailer?

The trailer features a hand-built metal body with visible craftsmanship in tube joints and welds for an authentic scale look. The nylon wheels and metal hardware combine for a realistic aesthetic that complements custom paint and weathering work. Its construction also invites further modification and detailing by modelers.

• Hand-formed metal tube body with realistic joints.
• Nylon-mould wheels suited to painting and weathering.
• Hardware designed for easy customization.

It fits those who enjoy hands-on upgrades, detailing, and light towing at events or on display shelves. If you need a rugged, customizable trailer that mates with INJORA's bumper hitch system and holds up to regular hobby use, this is a practical choice.
