Replacement Parts


Ground Control policy regarding the sale of replacement parts:

Ground Control Suspension Systems is a company that has dedicated all of its resources to creating a system of dampers, springs, machined aluminum, bearings etc. to work together in harmony. Ground Control is willing to sell the parts to restore or repair an original Ground Control Suspension System to its original configuration and intended use.

We do not sell any parts to repair or patch up kits sold by other companies. If you need parts or repair of a suspension manufactured by another company, we recommend you contact the manufacturer. 

Ground Control also does not sell “half-kits”. Ground Control cannot sell just the front or rear system, because it is impossible to create a tuned suspension system when someone else has manufactured half of the parts to an unknown specification. This would be the same as selling a ”left side only” suspension to match something else on the right side.

Sales of replacement parts for Ground Control Suspension Systems are evaluated on an individual basis. Please reach out through our replacement parts contact form for any inquires.

Ground Control policy for used parts and springs:

Ground Control Suspension Systems Inc. has always offered a lifetime warranty on our complete suspension kits. In order to continue to offer the lifetime warranty, we can only assemble and sell a complete, tested, matched and guaranteed suspension kit.

In consideration of our many, long time Ground Control customers, we are willing to assemble kits using springs or parts already purchased from Ground Control Systems by the original owner.

What this means is that, if you have already purchased parts from Ground Control, and would like to modify, change or upgrade your existing suspension kit, you may send your parts to Ground Control and we will reassemble your parts into the kit you wish, if possible.

Of course there can be no guarantee that the reconfigured kit will cost the same, but you may save money, time, and have the satisfaction of continuing your lifetime warranty against defects from Ground Control Suspensions.

This offer is only considered for the original purchaser, using parts exclusively supplied, and directly from Ground Control.

The customer is responsible for all shipping, and a Returned Goods Authorization number (provided by Ground Control in advance of all returns) will be required.
