The Serpent 402007 Magnesium Gear Differential Outdrive Set brings lightweight, race-minded components to 1/10 scale touring cars. Machined from magnesium for a strong strength-to-weight balance, these outdrives help reduce rotating mass and improve throttle response while still standing up to regular club and competitive use.
Magnesium delivers an excellent strength-to-weight ratio, so swapping to magnesium outdrives reduces unsprung and rotating weight without a big durability tradeoff. That weight saving helps acceleration and mid-corner response, which many drivers notice when dialing in lap times.
The Serpent 402007 fits a broad range of 1/10 scale touring car drivetrains. Installation is straightforward on most touring car diffs; use proper lubricant and a small amount of thread locker where applicable, and check gear mesh after fitting to avoid premature wear.
