GMADE R1 Adjustable Main Drive Shaft Set Front & Rear GM237SAA by GPM  [GM237SAA]

Front and rear adjustable main drive shafts

This centre main drive shaft set is intended for the GMADE R1 ROCK BUGGY, model GM237SAA. Steel retention pieces are combined with an aluminium 6061 T shaft body to give a compromise between strength and lighter rotating mass.

The front shaft adjusts from 122mm to 132mm and the rear from 105mm to 115mm, allowing you to fine tune driveline geometry without fabricating fixed-length parts. Screws are secured using a steel wire ring to reduce the risk of loosening under vibration.

From a service and tuning view the aluminium shaft body lowers inertia versus all-steel designs, which can help driveability. The adjustable design makes trimming and matching to slipper or differential spacing quick and reversible.

Select these shafts for drivetrain replacements or when adjustable lengths simplify setup tasks; always verify final lengths and check the wire ring after early test runs.
