1-inch Aluminium Beadlock Rims for TRX4M TRX4MZSP1216 by GPM  [TRX4MZSP1216]

1-inch aluminium beadlock wheels for TRX4M-compatible rigs

This GPM TRX4MZSP1216 wheel kit offers machined aluminium beadlock halves sized for 1-inch internal tyre diameters, intended for hobbyists running TRX4M and other 1/14 to 1/24 scale crawlers. The metal construction gives a more authentic appearance and firmer hardware mounting than stock plastic rims.

Fit guidance: rims require tyres with a 1-inch inner diameter and are supplied as unassembled parts. The centre clamp ring has vents to assist tyre seating and permit careful trimming where needed. Matching parts in the same product family are listed, including TRX4MZSP19A/B through TRX4MZSP24A/B for tyre and adapter selection.

Assembly and performance tuning: the set includes wheel halves, screws and metal weighting feeders; proper clamping and even torque are important for bead security and rotational balance. The weighting feeders allow incremental mass changes to tune traction and wheel inertia for technical crawling.

If you want stronger, more scale-accurate wheels for trail crawling, these aluminium beadlock rims are a sensible upgrade; ensure tyre ID compatibility and be prepared to assemble and balance the wheels.
