Replace the stock rear units on your ARRMA KRATON 4X4 4S BLX with these GPM aluminum dampers for improved longevity and smoother action. Machined from aluminum 6061 T6, they keep weight low while boosting component strength. The set includes extra spring coil choices to adjust response and a thicker damper shaft to reduce flex. Use the adjustable top spring retainer to alter spring hardness and dial in rear end behaviour for different surfaces.
