Skyjacker Black Max Shock Absorber 1977-1979 Ford F-150

Engineered for Drivers Who Refuse to Compromise Ride Quality

The Skyjacker B8556 Black MAX shock absorber is a twin tube, foam cell hydraulic shock built to restore factory level control or support a modest lift, depending on the application. Foam cell technology compresses under heat to manage oil expansion, so the B8556 keeps consistent damping through hard use instead of fading on washboard roads or long descents. Arc welded end mounts and vehicle specific valving mean this is not a generic universal shock forced onto your application, it is tuned for the exact platform listed below.

Key Features

• Twin tube construction with increased fluid capacity for better heat management
• Foam cell technology eliminates internal air, allowing mounting in any direction
• 360 degree arc welded end mounts built to handle repeated off road and towing loads
• Vehicle specific valving calibrated for the listed application, not a generic universal tune
• Chrome plated shaft resists pitting and corrosion for a longer service life
• Black protective boot shields the shaft from debris and road grime

Frequently Asked Questions

The B8556 is a Skyjacker Black MAX twin tube foam cell shock absorber built for the specific vehicle applications listed in the fitment table above. It uses vehicle specific valving rather than a universal tune.

Skyjacker recommends replacing shocks in axle pairs (both fronts or both rears together) so damping stays balanced side to side. Replacing only one side can cause uneven handling.

Check the fitment table and lift height range for your specific application before ordering. Black MAX shocks are valved for specific ride height ranges, so the wrong length can bottom out or over extend.

A basic shock swap at stock ride height typically does not require an alignment, but if the shock is paired with new springs or a height change, an alignment check is recommended.

Most applications require basic hand tools including sockets, wrenches, and a torque wrench. Some vehicles may need a spring compressor or jack stands to safely access the mounting points.

No special break in period is required. The shock is ready to perform to full specification immediately after correct installation and torque of the mounting hardware.

The Black MAX uses foam cell technology and heavier duty twin tube construction compared to many OEM shocks, giving more consistent damping under repeated heat cycling and rough terrain use.

Skyjacker backs the Black MAX shock body with a limited lifetime warranty against manufacturing defects. Normal wear items and damage from improper installation are not covered.

Installation Instructions

1. Raise and safely support the vehicle on jack stands, then remove the wheel on the side being serviced
2. Support the axle or control arm as needed so it does not drop when the old shock is removed
3. Remove the upper and lower mounting hardware and take out the old shock absorber
4. Position the new Skyjacker shock absorber and hand thread the upper and lower mounting hardware
5. Torque all mounting hardware to the vehicle manufacturer specification
6. Repeat on the opposite side if replacing the pair, then lower the vehicle and re-check torque
