48mm Urethane Rear Torsion Bar Round Grommets

Upgrade your rear suspension setup with these 48mm urethane smooth outer grommets, designed to suit Type 3 IRS outer locations and adjustable spring plate outer ends.

Made from durable urethane, these grommets offer superior strength and longevity compared to soft rubber alternatives. Urethane is more resistant to squashing, distortion, and bottoming out—making it ideal for performance builds, off-road applications, or anyone seeking a more responsive rear suspension.

These grommets have a 48mm (1 7/8″) inside diameter and are designed to match the fitment requirements of specific spring plate configurations.
