Coil springs are a very cost effective spring to use when you are building a link suspension system. They are widely used on many different vehicles and have a huge array off aftermarket options to chose from. We offer our coil spring axle bracket in two different diameters of 5.5 and 7 . These brackets are a low profile design so that they do not add unwanted lift but still give you room to get a wrench under them to tighten the spring retainer. These are sold in pairs.
