<strong>06. </strong> We used a floor jack and a pry bar to compress the coil far enough to be able to get the knuckle on to the new ball joints on the Chassis Tech A-arms. As with any new coil spring, our coil springs will eventually settle about 1.5 inches after a short trip out in the dirt. No matter what tricks you use to install coils and A-arms, it’s almost guaranteed to be dangerous and scary. Strapping the coils somehow can be cheap insurance that one won’t pop out and whack someone’s noggin during installation.
