Built to Soak Up the Abuse of a Lifted F-150
The Fabtech FTS81160 Dirt Logic 2.25 rear shock replaces the factory damper with a larger, more robust unit engineered specifically for trucks running Fabtech's 6in lift system. A 2.25in stainless steel body and 2.0in billet aluminum piston give this shock the volume and control needed to keep a heavier, taller F-150 composed on the highway and confident off it.
Key Features
- 2.25in OD stainless steel shock body resists corrosion from road salt and moisture
- 2.0in OD billet aluminum piston delivers consistent damping under load
- 7/8in NitroSteel black piston rod reduces pitting and extends seal life
- Polyurethane mounting ends quiet road noise at both ends of the shock
- Valving pre tuned specifically for Fabtech's 6in F-150 lift system
- Dividing piston keeps nitrogen gas and oil separate to prevent fade

FAQ
What is the FTS81160?The FTS81160 is a Fabtech Dirt Logic 2.25 rear shock absorber built for the Ford F-150 as part of Fabtech's 6in lift system.
Does the FTS81160 fit a stock height F-150?No. This shock is valved specifically for trucks running Fabtech's 6in lift system and is not intended for stock ride height applications.
Do I need to replace both rear shocks at the same time?Yes, replacing shocks in pairs is strongly recommended so damping characteristics stay matched side to side.
Will this shock work with larger aftermarket tires?Yes, Dirt Logic 2.25 shocks are pre tuned to account for the larger, heavier tires typically run on a lifted F-150.
Does installing this shock require an alignment?A shock swap alone does not typically change alignment settings, but it is good practice to have the alignment checked after any suspension work.
What tools are needed to install the FTS81160?Installation uses the factory mounting points and hardware, and most installs can be completed with standard hand tools.
Is there a break in period for this shock?No special break in period is required, though damping may feel slightly firmer until the shock settles in over the first several drives.
What warranty does Fabtech offer on this shock?Fabtech backs the Dirt Logic 2.25 shock with a limited manufacturer's warranty against defects in materials and workmanship.
Can this shock be used with a reservoir upgrade later?The Dirt Logic 2.25 platform offers an optional reservoir configuration, but the FTS81160 is the non reservoir version and is not designed for a bolt on reservoir conversion.
Install Instructions
- Support the vehicle securely and remove the wheel if needed for clearance
- Remove the factory or existing rear shock from the upper and lower mounts
- Position the FTS81160 in the mounting locations and hand thread the retaining hardware
- Torque the upper and lower mounting hardware to factory specification
- Repeat on the opposite side to keep damping matched
- Cycle the suspension by hand to confirm clearance before lowering the vehicle
Fabtech
Fabtech is a California-based suspension lift kit and off-road suspension manufacturer that has been engineering lift systems, control arms, sway bar disconnects, steering components, and performance shocks specifically for popular light trucks and SUVs since 1984. The brand's commitment to proper engineering, including in-field testing on real vehicles and multiple fit checks before releasing any kit, produces suspension systems that integrate cleanly with factory TPMS sensors, electronic stability control, and factory ABS systems that many cheaper lift kit manufacturers ignore. Fabtech lift kits for Ford F-150, F-250, F-350 Super Duty, Chevrolet Silverado, GMC Sierra, Toyota Tacoma, Ford Bronco, and Jeep Wrangler are among the most popular because the brand covers all major market truck platforms with model-year specific kits rather than generic universal designs. Serious off-road enthusiasts and truck owners who plan to run 33 to 40-inch tires with confidence that the suspension ...

Suspension
Aftermarket suspension systems improve handling, ride quality, and ride height adjustment beyond what the factory suspension provides. From lowering springs and coilover kits for sport handling to lift kits and leveling kits for truck and SUV off-road capability, quality suspension components transform how a vehicle rides and handles. Popular Suspension Upgrades Popular suspension upgrades include coilover kits for adjustable ride height and damping, sport lowering springs for improved handling and reduced body roll, performance shock absorbers and strut assemblies, sway bar and end link upgrade kits, subframe brace kits, and complete suspension packages for lifted trucks and off-road SUVs. Alignment kits including camber bolts and camber arms are also frequently ordered after ride height changes. What is the difference between coilovers and lowering springs? Coilovers are complete shock and spring assemblies with adjustable ride height set by threading the spring perch on the shock...
