These aluminium hex adapters are a purpose-built RC accessory to adjust wheel track and clearance on compatible 1/8-1/10 scale models. The adapter lifts the hex centreline to 18.5mm from bottom to top, increasing the distance between the wheel mounting face and axle reference compared with many stock hex heights.
Supplier design notes identify three tightening holes and an extended overall length to suit typical axle and pin dimensions, enabling a wider wheelbase while keeping wheel retention secure. The component is intended for tuning and fitment work on models that match the hole pattern or can accept the provided screw sizes.
Measured fit variances from the source are: compared with Thunder Tiger K-Rock G5 the adapter is 6.5mm taller than the original 12mm; compared with Team Magic E6III it is 3.5mm taller than the original 15mm; and compared with ARRMA NERO / FAZON it is 13mm taller than the original 5.5mm.
Choose these adapters for a controlled increase in track or to gain extra steering clearance on crawl-focused builds; verify hole spacing and hex height against your axle before fitting.
