Heavy Duty shock spring for IRC Big Bore Baja shocks for Rear shocks.
These Springs are aimed at rides running large engines or heavily upgraded that need extra spring stiffness. We recommend running the spring retainers with extra depth also with these springs.

Made from 100% 3.0mm British Spring steel for constant spring load while under heavy load with a matte black Powder Coat finish. Direct replacement to the stock silver IRC spring.

includes: 2x HD Rear Springs.
