2" front coil spring spacers with 5/8" stud extenders will remove the factory "rake" from your Ford F150 or Explorer. Daystar uses Polyurethane material to absorb the noise, vibration and harmonics that come from the suspension. Any 1991-94 Explorer to be lifted 1.5-2" will have alignment problems unless the factory shims are at or near zero degrees. Verify what is on your vehicle prior to purchase. Otherwise, a minimum of 4" of lift will be required in order to achieve correct alignment. No lift will be achieved on vehicles with big block engines.
