2" front coil spring spacers with 5/8" stud extenders will remove the factory "rake". 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's on your truck 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.
