KYB Suspension Strut P/N:3340199
KYB 551121 front suspension strut assembly for the 2007-2013 Chevrolet Silverado 1500 and other vehicles replaces a worn strut with a high-pressure monotube gas design. This KYB strut assembly is offered as an OE monotube replacement to restore the vehicle's original capabilities. The KYB suspension strut helps keep electronic safety systems performing as designed.
A leaking strut, a bouncy ride or a clunk over bumps can mean a strut is worn, though a worn strut mount or a loose sway bar link can be behind them too, so find the source before you replace anything.
This strut is listed for a wide range of Chevrolet, GMC and Cadillac models, led by the 2007-2013 Chevrolet Silverado 1500, the 2007-2013 GMC Sierra 1500 and the 2007-2014 Chevrolet Tahoe. The front axle takes two, and struts are normally replaced in pairs. If your truck or SUV is not named here, open the "Vehicles it fits" section to check your exact model and engine.

What is the triple chrome plated rod on the KYB suspension strut assembly for?
