This 2.5" Lift Dual Rate coil-spring Kit is designed to improve your ride quality and handling. The progressive spring rates maintain a plush street ride and excellent performance off-road. This kit also comes with two alignment cams. These cams will realign your front wheel's caster and minimize the steering pull usually found with lifted Super Duty's.
When using the TEI Spacer (Part#61600) in conjunction with a FSD 2.5" Leveling Coil-spring Kit, the supplied alignment cams may not add enough castor and additional parts may be required
