Bilstein's 33-185590 is a B8 5125 shock absorber for 1975-2007 Chevrolet Silverado 1500 & Ford Bronco & GMC Sierra 1500. It uses Bilstein's monotube construction, which keeps the gas and oil separated so damping stays consistent under sustained use.
Bilstein B8 5125 shock absorbers are designed for custom applications and are a perfect solution for vehicles that do not have a direct Bilstein fitment. These high gas pressure monotube shock absorbers are sold by various lengths and valve rates to accommodate a wide range of uses and custom fitments. All B8 5125 shock absorbers come equipped with industry standard 5/8 inch hour glass bushings and are available in either an eye/eye or stem/eye mount configuration. The shock absorbers feature a 46mm piston with self-adjusting deflective disc valving. Bilstein B8 5125 shock absorbers are the ideal choice for custom suspension builders.
