Coilover Bracket Kit for Superior G-Body Suspension: UMI Performance 1978-1988 GM Vehicles
The UMI Performance 3054 Rear Coilover Bracket Kit, engineered for seamless coilover integration on Quick Performance axles. This kit excels as the ultimate suspension enhancement, surpassing factory setups and rival aftermarket brackets by delivering exceptional tunability, reinforced durability, and precise geometry adjustments for unmatched handling and ride quality. Built with advanced fabrication techniques in the USA from high-strength steel, it provides enhanced shock absorption, reduced unsprung weight, and optimized rear-end stability – ideal for dominating drag strips, carving corners, or cruising streets. Unlike standard or imported options, the UMI 3054 offers multiple mounting configurations to fine-tune shock positioning by up to 3/4 inch, ensuring perfect alignment and elevating your G-Body's dynamics to elite levels.
Why UMI?
In the realm of rear coilover conversions for 1978-1988 GM G-Body platforms with Quick Performance setups, the UMI 3054 reigns supreme with its innovative design and proven advantages. Here's what makes it the standout best choice:
Superior Tunability for Precision Setup: Multiple adjustment slots enable 3/4-inch variations in shock height and five trailing arm positions, allowing custom suspension geometry that boosts traction, minimizes squat, and sharpens response – eclipsing rigid, non-adjustable competitors.
Robust, Featherweight Construction: Fabricated from thick-gauge steel with exacting cuts and a protective coating, it matches OEM weight while offering vastly improved rigidity and longevity in harsh conditions, outlasting flimsier or corrosion-prone alternatives.
Seamless Quick Performance Compatibility: Tailored standoffs and mounts integrate flawlessly with Quick Performance's adjustable control arm brackets, supporting standard racing shocks without fabrication headaches – a level of plug-and-play ease unmatched by generic kits.
Real-World Dominance: Enthusiasts experience heightened control, better weight transfer, and refined damping, perfect for everyday use, high-speed launches, or aggressive track days. It redefines coilover upgrades, leaving bulkier or less versatile options behind in terms of efficiency and feel.
Premium American Craftsmanship: Sourced and assembled domestically with top-tier materials, it guarantees unwavering reliability that offshore or budget brands can't rival.
Opting for the UMI 3054 is a smart investment in excellence – a straightforward install that amplifies your vehicle's potential without the limitations of heavier, inflexible brackets from lesser manufacturers. It's the highest-regarded option for G-Body owners focused on peak performance, simple setup, and enduring worth.
Features:
- Effortless bolt-on application replacing stock components – minimal modifications needed.
- Works with various aftermarket shocks and coilovers featuring bearing mounts.
- Precision-engineered from superior steel for maximum toughness and accuracy.
- Weather-resistant finish for lasting protection and aesthetics.
- Preserves stock-like mass while introducing cutting-edge capabilities.
- Versatile for daily commuting, racing, and spirited driving.
Included
All essentials for a smooth upgrade come standard:
- Pair of rear coilover conversion brackets (Part Number: 3054).
- Upper reinforcement tab for added structural support.
- Full installation hardware set for secure attachment.
Basic setup requires no extras, but combining with compatible UMI components (e.g., P/N 3055 brace) maximizes benefits.

Hardware
Automotive hardware encompasses the fasteners, clips, retainers, and mounting hardware that hold virtually every component on a vehicle in place, from engine bay bolts that endure extreme heat and vibration to interior trim clips that must release cleanly during service without breaking. Quality automotive hardware from brands including ARP, Dorman, and OEM equivalent suppliers provides reliable clamping force and corrosion resistance that cheap hardware does not, reducing the likelihood of seized or stripped fasteners that turn a simple service into a time-consuming repair. For engine and high-stress suspension applications, ARP's heat-treated fasteners provide torque capacity and fatigue resistance that exceed standard hardware grade specifications by a significant margin. For interior, body, and trim applications, OEM-equivalent push pins, clips, and retainers from Dorman provide exact-fit replacements that insert and release correctly without the frustration of incompatible gene...

Hardware Kits - Other
Automotive hardware kits provide complete sets of fasteners, clips, and retainers for specific repair applications or general-use assortments that cover the most commonly needed sizes for a particular vehicle platform or repair type. A complete hardware kit for a specific job, such as a brake hardware kit with all caliper bolts, slide pins, and pad hardware, ensures every item needed for a professional repair is included in a single purchase rather than requiring multiple individual part searches. General-purpose clip and retainer assortments provide a broad selection of the most common push pin and Christmas tree retainer sizes used across multiple vehicle brands, allowing shops and home mechanics to address most trim and body clip replacements from a single kit. Hardware kits that include both the fasteners and the required lubricants or thread-locking compounds provide a complete solution for time-sensitive repairs.
