These GPM aluminium front upper arms upgrade the ARRMA SENTON 6S BLX suspension with stronger, lighter components. Made from Aluminum 6061 T6, they stabilise the chassis and front knuckle while keeping weight in check. Delrin collars reduce binding and help the suspension articulate cleanly.
The hollow construction gives a modern look and practical weight savings, while the alloy's tensile strength ensures the arms hold shape under demanding use. That combination helps keep the suspension geometry consistent during hard off-road runs.
Precision fitment delivered by the GPM arms improves steering accuracy and overall handling. Less friction at the pivot points means more predictable steering inputs and improved traction when cornering.
