Overview
Get race-grade damping for taller-stance 1/10 builds with the Hot Racing 120mm Aluminum Heavy Duty Big Bore Threaded Shocks. CNC-machined from 6061-T6 billet aluminum and finished in gunmetal and blue, these big bore threaded shocks are engineered for crawlers, trail rigs, and tall-suspension off-road vehicles that use 120mm shocks.
The big bore design provides more consistent oil flow at high shaft speeds, while the threaded body allows quick, precise ride-height and preload adjustment. Threaded collars with O-rings keep your settings locked in run after run, and the 3.5mm stainless shafts handle hard impacts without bending.
