UMI Performance
UMI Performance 82-92 F-Body 78-88 G-Body S10 Tubular Front Lower A-Arms Poly- 3031-B
UMI lower A-Arms are crafted from USA DOM tubing with CNC-notched tube ends for a precise fit. They are jig-built to ensure accuracy, allowing for easy bolt-on installation every time. All critical areas are TIG-welded for superior strength and a polished appearance. UMI's lower A-Arms also have an improved ball joint angle for lowered vehicles, providing additional tire clearance. UMI P/N 3031 lower A-Arms include greaseable fluted polyurethane bushings for a smooth, quiet ride. They come preloaded with polyurethane bump stops, steering stops, and premium ball joints. Extensive testing by UMI on the street, drag strip, and skid pad guarantees a quality product that can endure various types of abuse. UMI lower A-Arms are compatible with factory springs, lowering springs, and most coil-over kits without requiring any changes to the A-Arms. For exceptional handling and performance, we recommend pairing them with UMI upper A-Arms, part # 3033-2. The lower A-Arms are shipped fully assembled and ready for installation. Designed and manufactured with pride in Philipsburg, PA, USA, the lower A-arm hardware kit, Part # 3011, includes 12mm Grade 10.9 bolts, washers, and nylock nuts, providing all necessary hardware to mount the new UMI A-Arms to your vehicle. UMI lower A-Arms are 5 lbs lighter than the factory A-arm set while enhancing durability. The tubing is precision-bent on a programmable tube bender and CNC-machined for accuracy. They are jig-built and TIG-welded for strength and a clean appearance. Additionally, they come with greaseable, fluted polyurethane bushings, premium ball joints installed, and polyurethane bump stops. They are ready to simply bolt on and fit factory spindles, working seamlessly with factory springs, lowering springs, and coil-over kits such as Viking and QA1. The A-Arms feature a durable red or black powder coat finish and are proudly designed and manufactured in Philipsburg, PA, USA.
