Arrowmax AM-664090: Precision Quiet Drive

The Arrowmax AM-664090 Super Differential Gear 64P 90T delivers durable, low-noise performance for electric touring and pan cars. Its lightweight construction is engineered to retain strength while trimming rotating mass, helping with consistent drive feel during both competitive runs and casual practice sessions.

Tooth Design and Chassis Fit

The special tooth profile reduces meshing noise and improves engagement compared with conventional gears. Arrowmax AM-664090 fits many electric touring and pan car layouts and is offered in multiple sizes, from 86T to 110T in 64dp and 68T to 88T in 48dp, allowing tuners to pick the best ratio for their setup.

Balanced Weight and Strength

Selecting the Arrowmax AM-664090 helps you achieve a practical balance between low mass and mechanical resilience. The result is smoother, quieter drivetrain behaviour that suits both racers chasing lap consistency and hobbyists wanting dependable performance.

Compatibility depends on the gearbox and pinion spacing of your chassis. Measure your current gear dimensions and compare them to the Arrowmax AM-664090 sizing before purchasing.
The optimized tooth shape improves contact angle and reduces friction at the mesh point, which lowers vibration and audible gear noise during acceleration and steady speed.
Use a light gear oil formulated for metal differentials or the grease recommended by Arrowmax. Avoid excessively heavy oils that can increase drag and heat.
