HRSATF257 - 57t Mod 0.8 Steel Spur Gear Arrma 1:10 4x4 Blx

Heavy‑duty 57‑tooth spur gear with a 0.8 module (32 pitch) tooth profile designed as a direct replacement for the stock plastic spur gear in ARRMA 1/10 4×4 BLX vehicles. Precision CNC machined from hardened steel for increased strength and wear resistance under high‑power brushless systems, this gear resists stripping and deformation in demanding off‑road or bashing conditions. Black oxide coating adds corrosion protection and a tough finish that holds up to repeated use in dirt, mud, and moisture. Matches the tooth count and pitch of stock ARRMA BLX spur setups so it installs with factory slipper pads or optional metal slipper components without modification.

• Hardened steel construction for superior durability compared with stock plastic gears

• 0.8 module (32 pitch) tooth profile for high‑power brushless BLX applications

• 57 teeth calibrated to maintain stock gear ratio while improving longevity

• CNC machined and lightened design to reduce weight without sacrificing strength

• Black oxide coating for corrosion resistance and wear protection

• Direct fit for ARRMA 1/10 4×4 BLX models such as Big Rock, Granite, Senton, and Typhon

• Works with factory or Hot Racing aluminum slipper pads for proper mesh and performance
