CHECK OUT OUR STAGE 1 AND 2 KITS!!! Improve handling and fulfill your G-Body or S-10’s built-in performance potential by installing our tubular upper a-arms. The relocated ball joint plate on these a-arms permits greater positive caster. Expect improved steering feedback courtesy of increased caster and a precise feel due to the deleted bushings and replaced with roller bearings. Features include grease-able steel cross shafts and improved header clearance. These track-tested, jig built DOM a-arms are supplied with a durable gloss black powder coat finish which guarantees your performance parts stay beautiful on your street car, drag car, autocrosser or Pro-touring machine. 

Why Modified Front End Geometry is Needed

If you want to improve the handling of your ride, you must first understand what is wrong with the original geometry. From the factory, these cars were designed to understeer. To make them do this, they used a very short spindle with the upper A-arm at a steep downward angle, which results in a backward camber curve making the tires lean out of a turn, using only the edges of the tire. Not only is this bad for mechanical grip, it’s also why every stock Chevelle, S-10 or G Body wears the outside edges of the front tires. Below is a diagram of the stock geometry at rest, and then in a hard turn. Notice the severe angle of the tires. All of the cornering forces are placed on a very small area of the tire.

 To deal with this problem, there are several things that will help. Simply lowering the car will help to some extent, but not nearly enough to correct the whole problem. Bigger sway-bars will reduce the amount of bad camber gain, but again, it’s not enough… it’s like a band-aid on a gunshot wound. To fix the bad geometry, you need a taller effective spindle height. The “effective height” of a spindle is from the pivot center of the upper balljoint to the pivot center of the lower balljoint. Tall spindles with stock balljoints, or stock spindles with extended balljoint studs will both achieve this goal. Below is a diagram of the same car equipped with a taller effective spindle height. Notice that the tires remain near vertical using the entire tread evenly across its contact patch. This is key to getting the most grip, and life out of your tires.
