Product Description

The Energy Suspension 3.5213R Hyper-Flex Front Sway Bar Bushing Set is designed to replace factory rubber bushings on GM full-size trucks and SUVs equipped with a 36mm front sway bar. By upgrading to polyurethane construction, it significantly improves handling stability, reduces body roll, and enhances steering response.

Unlike soft OEM rubber, Hyper-Flex polyurethane maintains its shape under load, reducing unwanted suspension movement during cornering, towing, and heavy acceleration. This results in a more controlled and predictable driving experience, especially on GMT800 platform trucks.

Ideal for Silverado and Sierra owners seeking improved chassis response without altering factory suspension geometry, this kit delivers a durable and long-lasting upgrade over worn rubber components.
