The ARRMA MOJAVE 6S BLX Desert Truck Aluminum Front Upper Arms by GPM are designed with performance and durability in mind, using Aluminum 6061 T6 to provide robust support for the front suspension. Integrated Delrin collars minimise play at mounting points and help reduce friction for smoother articulation. The hollow arm profile maintains strength while limiting excess weight, making this a practical upgrade for improving front-end resilience.
