Replace stock shafts with the GPM GM237SAA set for the GMADE R1 ROCK BUGGY to get steel strength paired with 6061 T aluminium to cut weight where it matters. Adjustable front shafts span 122mm to 132mm and rear shafts 105mm to 115mm so you can fine tune fit and geometry. The design uses a steel wire ring to lock screws in place and avoid loosening in demanding use. The aluminium sections lower rotating mass which can lead to better battery efficiency relative to a full steel shaft.
