ARRMA Front/Rear Diff Set Spiral 43T 10k Oil RC Differential - ARA310957

The ARRMA ARA310957 Front/Rear Diff Set is a spiral 43T differential replacement designed for ARRMA RC vehicles, supplying both front and rear units in a single pack. Each diff comes pre-filled with 10,000-weight oil, which is suited to the torque and load demands of ARRMA's larger bashers and short course trucks. If your differentials are worn, stripped, or you're rebuilding after a hard crash, this set gets both ends of the drivetrain sorted in one purchase.

Key Features

• Spiral 43T gear cut reduces noise and improves load distribution compared to straight-cut alternatives
• Pre-filled with 10k weight differential oil for consistent action straight out of the packet
• Covers both front and rear differentials, so you're not mixing old and new hardware across the drivetrain
• Direct ARRMA spare part — style code ARA310957 — ensuring correct fitment for compatible models
• Rebuilding both diffs at the same time helps maintain balanced handling and even power delivery front to rear

• 1 x Front Differential Assembly (Spiral 43T, 10k Oil)

What You Need
