GPM MAS054 front upper arms are produced from Aluminum 6061 T6 to offer a strong yet lightweight replacement for the stock parts on the ARRMA SENTON 6S BLX. These arms support the chassis and front knuckle while the fitted Delrin collars reduce contact friction at the pivot points, aiding consistent suspension travel and repeatable handling.
The arms use a hollowed section to reduce unnecessary mass without compromising tensile strength, allowing the suspension to retain geometry under load. Material selection and design focus on long term durability and reliable fitment.
Precisely engineered tolerances improve steering response and front-end stability, which is beneficial for both high speed runs and technical off-road sections. Reduced play around the knuckle yields more predictable handling behaviour.
