TRX4M 1-inch Machined Beadlock Wheel Set TRX4MZSP1216 by GPM  [TRX4MZSP1216]

Aluminum 1-inch beadlock rims tuned for TRX4M builds

This GPM TRX4MZSP1216 kit supplies a set of machined aluminum beadlock wheel halves sized for 1-inch inner-diameter tyres, aimed at TRX4M platforms and other 1/14 to 1/24 scale crawlers. The aluminium construction offers a realistic scale look and stronger mounting surfaces compared with stock plastic rims.

Fit notes and compatibility: these rims accept tyres with a 1-inch inner diameter and arrive as loose parts ready for user assembly. The centre clamp ring includes vents to make tyre seating and any trimming easier. The listing cross-references matching part numbers in the same family, including TRX4MZSP19A/B through TRX4MZSP24A/B for tyre and adapter matching.

Assembly and tuning: the set contains wheel halves plus clamping hardware; careful assembly determines bead retention and dynamic balance. The included metal weighting feeders allow stepwise mass tuning at the rim to alter rolling inertia and fine-tune slow-speed crawling behaviour on scale lines.

For scale crawlers where a tougher, more realistic wheel is wanted, these aluminium beadlock rims are a practical upgrade; confirm tyre inner diameter before buying and expect to perform the final assembly and balancing yourself.
