Control arms locate the wheels in relation to the body and allow them to move within a designed range in response to the road and the suspension. They may pivot on bushings at both ends, like rear suspension control arms, or they may have a ball joint at one end, to enable a front suspension knuckle/spindle to rotate. Your factory control arms are fine for everyday use, but inadequate for performance driving with larger tires and other suspension mods.

Factory control arms don’t have the strength to withstand horsepower increases and aggressive driving. Your OE arms also may not have the clearance you need for wider wheels and tires, or allow the alignment angle adjustments needed when ride height is significantly altered, like on lowered cars or lifted trucks. Our performance control arms can handle the power, prevent tire rubbing, and provide the alignment angles you need for optimal handling.

Many vehicles like muscle cars with live rear axles have stamped steel U-section rear control arms that can bend and distort when a lot of horsepower is put to a set of big, sticky tires. We have box section rear control arms that are much stronger, so the axle stays in its designed position and doesn’t deflect. You get traction and all that power gets to the ground. These control arms usually come with firm, durable polyurethane bushings installed, and some are adjustable, so dimensions like pinion angle can be dialed in.

OE front suspension upper and lower A-arms, especially the stamped steel variety, can reveal their weaknesses when cars are road raced or 4WD trucks are lifted and driven aggressively off-road. These control arms can flex under severe duty use, resulting in poor handling and steering control, and can ultimately fail, leaving you with a DNF or stranded out on the trail. We can offer you strong but lightweight control arms manufactured from billet aluminum or exceptionally stout tubular 4130 chrome moly that is TIG welded and powder coated for durability. Most come with premium ball joints and performance polyurethane bushings installed.

Besides inadequate strength, many OE control arms are simply the wrong shape for racing and performance use. Racing and performance driving require wider wheels and tires for traction, and these may not fit without rubbing and clearance issues. Such wheels and tires and high speed driving generally require different suspension alignment angles for precise handling and control, and stock control arms may not have the range of adjustment necessary. Our performance control arms provide the clearance you need, with geometry that provides for proper caster and camber and improved stability and steering response. Many have enhanced adjustment features built right in to the control arm.

    How to Inspect Your Suspension System
    The very first thing to know about timely suspension system diagnosis is that the stability and steering control of your vehicle and, what is more important, your safety on the road depends on how often you make it. Automotive suspension belongs to one of those car systems that are constantly exposed to high loads and thus are prone to wear and tear. Most specialists recommend inspecting suspension system after every 6,500-7,500 miles or when there are any signs of its breakage.

    How Low Can You Go?
    Lowering is high on the list of many people who want to improve the appearance of their car. If you want to lower your car with the coil springs, then replacing them with lowering springs is the way to go. But what if you want to lower your car and also make it handle better? If that’s your goal then consider coil-over shocks.
