Rear performance shock absorber for 2000-2006 GM K1500 4WD trucks and SUVs, Fabtech FTS7240.
The Fabtech FTS7240 is a twin-tube hydraulic performance shock absorber designed to work with Fabtech lift and leveling systems on 2000-2006 GM K1500 4WD platform trucks and SUVs, while also functioning as a direct-fit rear replacement shock on stock-height applications. A 9/16-inch hardened chrome piston rod rides in a 1-3/8-inch OD piston, and high-flow 9-stage valving is tuned to control body motion and reduce fade during hard use, while a closed-cell foam insert further resists shock fade from heat buildup on rough roads or trails.
Key Features
- The FTS7240 uses twin-tube hydraulic construction for a controlled, predictable ride
- High-flow 9-stage valving is tuned for excellent damping performance under load
- 9/16-inch hardened chrome piston rod resists pitting and corrosion
- 1-3/8-inch OD piston paired with a closed-cell foam insert to reduce shock fade at speed
- Designed to work with Fabtech suspension lift systems as well as stock-height applications
- Sold individually; order two for a complete rear pair

About Fabtech
Fabtech engineers its Performance Shock line to complement its own suspension lift systems while also serving as a direct-fit stock-height replacement, and the FTS7240 brings that twin-tube, 9-stage valving design to the rear of 2000-2006 GM K1500 4WD trucks and SUVs.
FAQ
Is this shock sold individually or as a pair?This shock is sold individually; order two if you are replacing both rear shocks.
Can this shock be used on a stock-height truck?Yes. It is designed to work with Fabtech lift systems, and it also functions as a direct-fit rear replacement shock on stock-height applications.
What type of valving does this shock use?It uses high-flow 9-stage valving tuned for controlled damping across a range of driving conditions.
Does this shock help with shock fade during hard use?Yes. A closed-cell foam insert is built in to help resist shock fade caused by heat buildup during extended hard use.
What is the piston rod made from?The piston rod is a 9/16-inch hardened chrome unit designed to resist pitting and corrosion.
Does this shock fit both 2WD and 4WD trucks?This specific listing is for the 4WD rear application; confirm your drivetrain before ordering, as Fabtech offers separate part numbers for 2WD applications.
Is any special tool needed to install this shock?No special tools are required beyond standard hand tools and a jack to relieve suspension load during removal and installation.
Will this shock change my ride height?No. This shock is a performance replacement shock and does not itself add lift; it is valved to complement both stock-height and lifted ride heights.
Installation Instructions
- Raise and safely support the rear of the vehicle, then support the rear axle so it does not drop fully when the shock is removed.
- Remove the upper and lower mounting bolts securing the factory shock absorber, then remove the shock from the vehicle.
- Compress the new FTS7240 shock to match the factory shock's installed length, then position it at the upper and lower mounting points.
- Install the mounting hardware at both ends and torque to the manufacturer's specification.
- Repeat on the opposite side if replacing both rear shocks, then lower the vehicle and cycle the suspension to confirm clearance before driving.
