Energy Suspension GM Rear Spring & Shackle - Black

This kit gives you the black polyurethane bushings you need to replace the worn-out rubber components in the rear spring and shackle setup for your 1981-1986 Chevrolet K30. These bushings are made from Energy Suspension's Hyper-Flex performance polyurethane, a material known for lasting much longer than standard rubber parts. By ensuring your suspension can move correctly, these bushings help your truck handle better when you're turning, accelerating, or braking, and they also contribute to a more controlled ride over rough roads.

The Hyper-Flex polyurethane construction is a key part of what makes these bushings so durable. It's designed to resist the kind of wear and tear that often affects rubber over time, meaning you get a more consistent performance from your suspension for a longer period. This kit is specifically designed for your K30, with a 1 3/8 inch OD frame shackle and a 1.75 inch main eye, suitable for vehicles with a 3950 lb axle rating.
