GMADE R1 Adjustable Front & Rear Drive Shafts GM237SAA by GPM  [GM237SAA]

Front and rear adjustable drive shaft assembly

This centre main drive shaft set is made for the GMADE R1 ROCK BUGGY platform, model GM237SAA. It pairs steel retention bits with an aluminium 6061 T shaft to offer strength where needed and reduced rotating weight overall.

Adjustment ranges are 122mm to 132mm for the front and 105mm to 115mm for the rear, so you can dial in fitment and drivetrain geometry without cutting shafts. A steel wire ring is used to retain the screws and help prevent loosening under rough running conditions.

From a tuning point of view the aluminium sections lower spin mass compared with all-steel alternatives, which can help drivetrain responsiveness. The adjustable design makes it easier to match slipper clutch settings and differential spacing during setup.

Ideal when replacing tired driveline pieces or when adjustable lengths simplify setup; double check lengths prior to final assembly and inspect the wire ring after initial runs.
