Upgraded, lower, EN8 shock absorber pin. Especially useful for competion cars or street cars with lowered suspension. This can be very critical if the shock has any chance of bottoming out. And if you are adding shocks for the first time as on a wet to dry conversion or simply adding shocks to the front of your 'Hydro' car- then these pins are a must and the best option! See C-AJJ3359 for upper shock mounts for lowered cars.
