GPM MAG115R Precision Rear Dampers for ARRMA GRANITE 4X4

The GPM MAG115R rear dampers are engineered as a durable upgrade for ARRMA GRANITE 4X4 and BIG ROCK CREW CAB platforms. Constructed from 6061 T6 aluminium, the components deliver improved structural stiffness over stock parts. Reinforced spring coils and a larger 4mm damper shaft reduce deflection under load, supporting more consistent suspension behaviour during aggressive use.

Technical Benefits

  • Durability: 6061 T6 aluminium bodies provide a balance of strength and weight for robust real world performance.
  • Enhanced Cushioning: Filled with a high concentration suspension oil to stabilise damping and improve response.
  • Improved Stability: 1.6mm spring coils paired with a 4mm damper shaft to resist bending and maintain geometry under stress.

Fitment and Tuning Notes

Adjust the spring retainer to vary preload and alter the effective spring rate. This allows technicians and hobbyists to tune rear compliance for different track conditions or vehicle setups.

  • Rear Damper – 2pcs
