King 3.0 Performance Race Series Shocks are the top of the line smoothie shocks before entering King's Pure Race Series shocks. At 3 inches in diameter, they are massive so that they can handle the heat and forces generated by the largest of off-road trucks and buggies. Simply put, these shocks will take all the abuse you can possibly throw at them.

How to Measure For Shocks and Coilovers

Custom Built and Valved by King Racing
Even though a smoothie shock is relatively simple in its design, we still have King custom build them to our customer's exact specifications each and every time. After you've selected all of the features you would like to add to your shock, a build sheet is sent to a King Racing technician who builds your shocks by hand exactly the way that you want them. The best part is, this is a free service offered by Filthy Motorsports and it only adds a few days to your delivery date so you still get your shocks quickly.

Selecting Shock Valving
On larger shocks like this 3.0 smoothie, selecting the valving becomes tricky because even though the valves are large, they are still sensitive enough for very fine tuning. Filthy Motorsports and King Racing are here to make sure your shocks are valved to match your application perfectly. If you tell us about your suspension system and driving style in the "Shock Details" text box of the build menu above, we'll coordinate with our friends at King Racing to decide on the best valving for you. If we feel that additional information is needed, we'll be sure to contact you for it before your shocks move on to assembly. As you can tell, we take shock valving very seriously and we want to make sure that when your shocks arrive they are exactly what you needed.

Servicing, Tuning, and Rebuilding
Even though 3.0 shocks are overkill for most applications, years of abuse will eventually cause their internal parts to start wearing out. When that happens, you will be glad to know that your shocks have been designed for easy maintenance and tuning. With the right King replacement parts from Filthy Motorsports, all you will need are a few basic hand tools and a few hours of time to completely service your shocks. If servicing your shocks is something you would rather have us do for you, that is not a problem, just bring them by (or send them to us) and we'll get them serviced for you.
