If you have a 4" lift kit on your truck, these coilovers could potentially help with front sag and squat from a heavy bumper/winch/skid plate combo, since they can be adjusted up by a bit. However, if your truck does not have a 4" lift kit, you will need a different coilover option. Please call us directly at 623-434-5277 or email us at [email protected] so we can get more specific about your truck.
