1964 - 1972 GM A-Body 1.250" Solid Front Sway Bar

UMI Performance 1.250" (32mm) solid front sway bar is designed to reduce body roll, understeer and increase cornering capabilities resulting in a more balanced suspension. This front sway bar is over 400% more rigid than the factory 7/8" front sway bar and bolts directly in place with no modifications. Front sway bar is manufactured from 1.250" 4140 chrome moly steel, CNC bent and formed as one piece to insure maximum strength and performance. Each kit includes new Energy Suspension end links and greaseable sway bar bushings with new zinc plated clamshells. Sway bar is available powder coated bright red or gloss black for a durable long lasting finish.

1964 - 1972 GM A-Body 1" Solid Chromoly Rear Sway Bar

This beefy 1" solid rear sway bar is designed to reduce body roll, understeer and increase cornering capabilities resulting in a more balanced suspension. This rear sway bar also works to keep your vehicle level and straight during those hard launches. UMI's sway bar is manufactured from 1" solid 4140 chromoly steel, heat treated and formed as one piece to ensure maximum strength and performance.

GM A-Body Spring Kit, 1" Lowering

A spring is a spring right? Wrong! When UMI chose to manufacture their own line of springs they went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. These front springs are wound from 5160 CrSi premium wire and feature a linear 530 lb/in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the "œfloating" feeling so common with the A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 1" lowering with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ¼" nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.

• Features:
• onsistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come.
• inear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling.
• o more floating feeling.
• uitable for Pro-Tour, Auto-x and general cruising.
• " Lowering with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy as well as LS power.

UMI Monotube Shocks

The UMI Performance monotube shock package is designed to bridge the gap between basic street shocks and aggressive racing shocks. Medium-firm compression valving provides crisp handling and absorbs bumps while still providing a comfortable ride. The ramped up rebound curve slows body roll during transition and gets rid of that unwanted floating feeling. A high pressure nitrogen charge prevents shock fade during hard cornering and further increases performance. UMI Performance monotubes feature race proven technology with street friendly valving. These shocks are suitable for street, corner carving, Pro-Touring and non-competition drag racing (contact us for competition drag racing suggestions). UMI Performance shocks are 100% manufactured in the USA.

1968-1972 GM A-Body Control Arm Reinforcements/Frame Braces

Trailing arm mount braces are designed to reinforce the upper and lower front control arm mounts on your classic A-Body. The more power your ride makes the better chance of bending or breaking the rear control arm mounts. These tubular reinforcements tie the upper and lower control arm mounts together for added strength and driving performance. Control arm braces are manufactured from DOM steel; TIG welded and feature adjustment for a perfect fit on all 64-67 A-Body's. Kit includes new longer Grade 8 hardware, nuts and washers.

1968-1972 GM Polyurethane Rear End Housing Replacement Bushings

Replace your rubber OEM rear end housing with an Energy Suspension polyurethane setup. Over years, rubber OEM bushings dry rot, crack and harden, decreasing your ride quality and performance.

This is an excellent upgrade for your street or track driven vehicle. (2 per set)
