The GPM MAKX187R/L rear dampers are CNC focused upgrades for ARRMA KRATON 8S applications, manufactured from 6061-T6 aluminium to reduce mass while improving structural strength. Spring wire moves from 2.5mm to 2.6mm with a 2.8mm option for higher spring rates. Shafts are enlarged to 6mm and polished to lower the risk of bending and maintain consistent piston travel. The L-shape piggy back reservoir increases oil travel length to stabilise damping under repeated loads, supporting better setup tuning and repeatable performance.
