Bilstein B8 5160 Front and Rear Remote Reservoir Shock Kit
This four-shock package lists Bilstein 25-177435 front shocks and 25-177442 rear shocks for compatible 2005–2016 Ford F-250 and F-350 Super Duty 4WD applications. Match each axle to its actual suspension height rather than assuming a nominal 6-inch lift applies equally front and rear.
Included components
- Two 25-177435 front remote reservoir shocks — front application: 4–6 inches of existing lift.
- Two 25-177442 rear remote reservoir shocks — rear application: 4 inches of existing lift for the listed 2005–2016 applications.
Current manufacturer cross-references
Bilstein's current catalog lists 25-177435 under the interchange references for front shock 25-311815, and 25-177442 under the interchange references for rear shock 25-311822. The current replacement application tables overlap for compatible 2005–2016 F-250 / F-350 4WD trucks at the axle-specific heights above. Confirm the supplied part-number version and exact vehicle application before ordering.
Lift-height compatibility
These shocks accommodate an existing lift; they do not raise or level the truck. The front 4–6-inch range does not establish 6-inch rear-lift compatibility. Springs, lift blocks, spacers and other lift-producing components are not listed as included.
Remote reservoir damping
Bilstein B8 5160 shocks combine monotube construction with remote reservoirs for additional oil capacity and heat dissipation. Application-specific velocity-sensitive digressive damping helps control suspension movement as road and trail inputs change.
