These are great shocks for heavier tires and wheels, and lifts. I got these longer shocks after a lift and I do have to say they aee much stiffer than the Bilstein 4600 shocks I previously used. More of a truck ride than a car ride in my 2005 Excursion. Nonetheless, they do they job and are Billstein quality. Compressing these shocks for mounting takes more muscle than I have. But I have a jack.
