What is an Ultra™ Cartridge?
A typical strut must be replaced as an entire unit. The hydraulic wear-out items – piston, seals, tube and rod – are contained in the tube-and-rod assembly, which is permanently enclosed in the strut body.

In some strut designs, however, these wear-out items can be replaced or upgraded separately, with a new cartridge. A Gabriel® Ultra™ Cartridge is a self-contained tube-and-rod assembly, with all new hydraulic components, to replace your worn-out parts. Because it is an Ultra design, you can be sure that it has a super-finished chromed piston rod and G-Force™ Technology, providing you with superior corrosion protection and the perfect combination of safety, performance and control in your car’s ride.
Gabriel cannot determine whether any particular customer is qualified to check or replace ride control, shocks or struts. Customers must make their own assessments of their experience, skills and knowledge and take responsibility for all results and if in doubt, seek the assistance of a qualified trained mechanic.

Every vehicle is delivered with an OEM owner’s manual. If you cannot locate yours, several publications exist that will provide you with the specifications for the parts on the vehicle you are about to repair. Read the OEM manual specific to the make and model of your vehicle and the instructions that accompany your Gabriel product before undertaking any repair or replacement project. Always seek the advice or assistance of a qualified, trained professional when needed.
Before starting and vehicle repair or replacement project, you must have the proper training, tools, equipment and experience necessary to safely and correctly complete the project. This is especially important for anyone attempting to replace a worn strut or shock absorber, because failure to remove the worn part or install the replacement parts correctly on your vehicle may result in personal injury or damage to property.
