What is the benefit of the taller ball joints included in this kit?

The taller upper and lower ball joints help to optimize the suspension's roll center and increase camber gain during cornering. This can lead to improved traction and better handling characteristics.

Does this A-arm kit come with everything needed for installation?

The kit includes the upper and lower A-arms, Delrin bushings, rod ends, and an adjustable steering stop. UMI recommends adding their P/N 3060 bump steer kit for optimal performance, which is sold separately.

How does the removable lower shock mount benefit the user?

The removable lower shock mount allows for easier spring and shock replacement without needing to remove the spindle. This is particularly convenient for trackside adjustments.

Product Details

If you're looking to significantly improve your classic GM G-Body or S10/S15's front-end grip and handling, UMI Performance's 305756-3 coilover A-arm kit is a solid option. This kit is designed to bolt directly onto a wide range of vehicles, including popular models like the 1978-1988 Chevrolet Monte Carlo, 1982-2003 Chevrolet S10, and 1978-1987 Buick Regal. It's built to work specifically with coilover shock setups, allowing for a lower ride height and optimized suspension geometry.

This kit brings a host of features to the table. The upper and lower A-arms are constructed from USA-made DOM steel tubing for strength. UMI has relocated the ball joints to achieve up to 10 degrees of caster, which really helps with steering feel and straight-line stability. The lower ball joint is taller, optimizing the roll center and further lowering the vehicle's center of gravity. For smooth operation and reduced deflection, the lower arms use Delrin bushings, while the upper arms feature rod ends for easy alignment adjustments. You'll also find a double shear sway bar mounting system that works with UMI's own sway bars and many aftermarket units. An adjustable aluminum steering stop is included to prevent tire and wheel damage by limiting steering lock.

The lower shock mount is designed to be removable, making spring and shock changes much easier, especially at the track. UMI recommends adding their 3060 bump steer kit for the best possible performance from this A-arm setup. This kit is manufactured and tested in the USA, drawing on UMI's racing experience.
