Product Description

The UMI Performance 3054 kit provides a robust and adjustable solution for converting the rear suspension of 1978-1988 GM G-Body vehicles to coilovers. By offering vertical shock adjustability and multiple trailing-arm positions, it allows precise tuning of ride height and suspension geometry for both street and racing applications.

Constructed from thick laser-cut steel and reinforced with an upper T-bar tab, these brackets are designed to handle the loads of performance driving. The ±¾" shock mounting range gives flexibility in selecting your ideal spring and shock setup, while the trailing-arm adjustability helps dial in the handling characteristics of your vehicle.

Installation requires only minor drilling for setup, and the powder-coated finish ensures long-term durability. If you're building a G-Body for road racing, autocross, or serious performance driving, the 3054 bracket set is a foundational upgrade for a custom coilover rear end.
