Get firmer, more consistent damping with the GPM 6061-T6 Alloy Front/Rear Adjustable Progressive Spring Shocks made for the ARRMA QUAKE GROM Monster Truck. These units are charged with 500cSt silicone oil and fitted with a sealed cover to resist contamination and extend service life.
The progressive spring profile provides a compliant initial travel that firms up as load increases, helping the truck soak small impacts while controlling bigger hits for better overall stability.
This set ships with both black and silver progressive springs so you can tune ride height and stiffness. The black spring has a 1.1mm wire diameter and the silver spring is 1.2mm for a firmer response.
