Direct Fit

Direct fit replacement; not only will the part fit correctly, but it will function correctly.  Many competitors combine applications to cut down on the amount of parts they have to carry. This can result in the following issues: incorrect vehicle height, poor response and an uncomfortable ride.

Rigorously Tested

Rigorously tested and made from higher quality materials than the competition. Our parts are built to have a longer life in any environment or road conditions.

Matched Parts

When you buy the kit pre-built by us, you can be sure that the parts are matched for optimum performance.  Not all shocks and struts are manufactured the same, so mixing and matching can result in fit issues and potentially decrease the life of the parts.

Saves Time & Money

When you buy one of our kits, you not only save money over buying the parts individually, but you also save time having to search for all of the different parts that are correct for your vehicle (because we did it for you!)

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

Where do I find my RPO code ?
Marvin W on Feb 18, 2017
BEST ANSWER: You can usually find RPO codes on a sticker located in the glove box. Other locations could be the driver door, spare tire well or trunk lid, but it will depend on your vehicle.
Just to clearify, this replaces the auto leaveling shocks?
Zac S on Dec 28, 2016
BEST ANSWER: No, these will be fit for models that were equipped with standard suspension from the factory. If your vehicle had auto leveling shocks from the factory, then a separate bypass set up will be required.
