Bulged design provides increased fluid capacity and cooler operation in extreme conditions
Solid steel eye rings & 360° arc-welded end mounts deliver tough tensile strength that reduces end mount failures
Chromed piston rod to inhibit corrosion, ensure proper seal lubrication and provide a more consistent wear surface
Anti-corrosion end mounts to inhibit rust & corrosion
Durable piston seal design
Formulated shock oil for exceptional anti-fade performance

Is it normal for FleetLine shocks not to extend when taken out of the box?

This is normal, and by design! FleetLine shocks are hydraulic, like most shocks chosen by OE manufacturers, and therefore don't expand when taken out of the box. Whether a shock is gas-charged or not does not determine its quality or performance.

Why isn’t FleetLine gas charged?

Some competitors gas charge their shocks to reduce performance loss. FleetLine’s non-gas proprietary valving system delivers 20% better anti-fade performance than even the competitors - meaning you'll RUN LONGER & RUN STRONGER!

I have a light film of oil on my shock, does it need to be replaced?

Probably not. Shocks are designed to "mist" slightly & this film helps lubricate the seal as the piston rod moves. A light uniform misting is normal, but streaking patterns aren't and should be investigated. Remember: If it's streaking, it's leaking!

My tires are unevenly worn. Do I need to replace my ride control components?

Possibly. Cupping of the tires is commonly seen as an indicator of worn shocks However, other types of tire wear can also be caused by worn ride control parts.

How can I check my HD shocks?

Gabriel recommends you have your commercial vehicle shocks visually inspected every 15,000 miles and perform the Gabriel Heat Test every 50,000 miles. More information at CheckYourShocks.com
