These springs will give your Scout a superior ride quality and driving experiance. They do well both on and off road. The high carbon steel used in construction of these USA made springs make them a lasting solid upgrade for your comfort. 31" -33" tires will fit depending on brand and width of tire. the 33'x10:50-15 will rub under full compression, but one of our body lifts will raise the wheel wells up to keep that from hapening. The other option would be some extended bumpstops for the uptravel. Your scout will ride better than it did from the factory. NOTE: we recomend this with our full 80/800 suspension package that includes the extended brake lines, shock absorbers, u-bolts, poly bushings. Does not include spring bushings. See related products.
