TRX-4 brass shock spring under cap

Looking for an upgrade for your TRX4 shocks? Consider the TRX4 brass shock spring under cap set from Samix. This set includes four high-quality brass under retainers that add a weight of 25g to the bottom of the shock. This added weight improves the truck's climbing performance, while also increasing the rigidity and durability of the shocks. Unlike standard plastic caps, these caps have a non-slotted design, which prevents them from falling out when using soft springs. The caps are also black coated to prevent oxidation and have the SAMIX word etched on them for added style. Upgrade your TRX4 shocks with the TRX4 brass shock spring under cap set for better performance and durability.
