AFTERMARKET CONTROL ARMS SOLVE A LOT OF ALIGNMENT ISSUES
A BETTER HAMMER
AFTERMARKET control arms sound fantastic, don’t they? And they really are. They solve a lot of alignment issues, add strength back into a system pushed to its limits, and make your tyres last longer. If that’s not enough, they can also increase off-road performance.
So how do they give better off-road performance? By fixing a problem you’ve created. As your suspension is lifted, the upper control arm becoming angled causes more issues than just your alignment. The first is binding of the upper ball-joint. It locks up with too much angle limiting down travel and wearing prematurely. Likewise, the upper control arm wrapping around the strut means, with too much angle, it’ll also foul. By re-angling or redesigning ball-joints, as well as making more clearance around the strut tower and the tyre, redesigned control arms give more wheel travel, meaning your 4x4 has tyres on the ground for longer and there’s less chance of losing traction.
While there are legal minefields around both buying and installing control arms, reputable manufacturers make it a smooth affair and can make your lifted 4x4 perform better off-road and handle better on-road. It’s no wonder they’re becoming more and more prevalent in complete suspension kits.
