UMI Performance tubular A-Arms are designed to outperform the stock setup whether it?s at the race track or an added improvement to your daily driver; they've been tested and improved to handle both applications. These A-Arms are designed to add front end rigidity, increased strength and to eliminate flex found with stock A-Arms. A-Arms are built using strong DOM steel tubing, 3/16? thick CNC machined ball joint mounts and are supplied with grease-able Energy Suspension polyurethane bushings. The lower A-arms are supplied with high quality spherical bearing rod end on one end of each lower A-arm. This design is to allow free movement and travel in the front suspension and prevents bushings bind. The factory GM A-Arm features a rubber pivot bushing in this area; this is designed to rotate up and down as the suspension travels. Replacing this bushing with a solid bushing such as polyurethane would not allow the suspension to articulate correctly and would cause front suspension bind. The rod end we use features a Teflon lined self lubricating race designed for a quiet operation. The lower A-arms also feature adjustment if needed while the upper A-arms are non-adjustable and feature an improved ball joint angle for lowered vehicles but work fine on a non-lowered vehicle. The lower A-arms feature new ball joints installed while the upper A-arms re-use the factory ball joint or new factory style ball joint. When do you choose adjustable upper A-Arms? A question we get asked a lot is when do I need adjustable upper A-Arms for my application? Adjustable A-Arms allow the operator to make front end changes such as improved caster and camber. These changes are very crucial when high handling such as autocross or road race is present. If caster or camber adjustments are desired they must be made by a professional alignment center. This procedure may take time and involve extra cost. If your vehicle is exposed to street driving and/or drag racing these upper A-Arms are the perfect set-up for you.
