ARRMA Limited Slip F/R Diff Set GP4 5mm 10k RC Differential - ARA310990

The ARRMA ARA310990 Limited Slip Differential Set is a front and rear diff replacement designed for ARRMA GP4 platform vehicles, using a 10,000-weight silicone fluid for consistent, controlled power transfer. This RC differential set addresses one of the most wear-prone components in hard-driven ARRMA models, keeping front and rear axle response predictable across a range of surfaces. The 5mm specification refers to the diff output shaft size, making fitment compatibility straightforward when cross-referencing against your ARRMA model's parts number.
