Arrowmax AM-601011 Modul1 Ultra Pinion 11T Spring Steel  [AM-601011]

Robust pinion designed for consistent drivetrain performance

The Arrowmax AM-601011 Ultra Pinion 11T Modul1 gives model enthusiasts a dependable replacement for worn pinions. Manufactured from spring steel, it maintains tooth integrity and reliable engagement under prolonged use.

Advantages of a spring steel pinion

Spring steel provides high fatigue resistance and stands up to high rpm loads without deforming easily. This material choice keeps gear mesh predictable and extends service intervals compared with softer options.

11T ratio for balanced handling and speed

Eleven teeth offer a sensible balance between torque and velocity, making the pinion versatile across different driving conditions. It suits both tuning for tighter handling and setups that need steady top speed.

Installation checklist and upkeep advice

Fit the pinion to the correct shaft size, set proper backlash with the spur, and secure the fastener to prevent slippage. Clean off debris regularly and use a light gear lubricant to protect against wear.
