4.5 Inch Rockzilla Suspension System w/ Fast CD Adjuster Coilovers For Jeep Wrangler JKU Rock Krawler - JKU45RZLA - Rock Krawler

Rock Krawler 4.5 Rockzilla Suspension System w/Fast CD Adjuster Coilovers For Jeep Wrangler JKU

The Rock Krawler Rockzilla System for the JKU is a state of the art suspension system designed for ultimate performance on-road and off road. Rockzilla suspension geometry is based on our 15+ years of off-road racing dominance in Jeep applications.

Whether that is winning King of the Hammers, several Ultra 4 National Championships, The World Championship of Short Course at Crandon, The Mint 400, Score Championships and Baja wins, it all plays a part in how we tuned the Rockzilla Suspension Geometry to flat out perform while not taking away from any street manors. Rockzilla features an independent 3 link front suspension with a double triangulated rear design.

Instant centers, roll centers, roll axis and reduced jacking have all been greatly improved compared to all other geometry configurations on the market today. Rockzilla turns your Wrangler JKU into a Swiss Army Knife.

A vehicle that can do it all and do it all amazingly. Rockzilla does not over dedicate itself to one form of off-roading over another.

We feel you make too many compromises when you just want to just Flex in the rocks or on a trailer. With Rockzilla you can drive comfortably on the street, rail corners in the desert, hit the whoops, play in the dunes and tackle any trail out there.

Each and every component is put through extreme tests; from the solid 2 x 3 7075 PB+J lower control arms, the 1/4 inch thick laser cut, formed and precision welded frame side mounts with weld schedules that do not rip apart the frame, to the incredibly tuned 2.625 RRD Racing Shocks/Coilovers, Rockzilla is dialed in!

Another thing that sets Rockzilla apart from all the other systems on the market that are similar in style to Rockzilla is; Rockzilla requires absolutely no cutting holes in the tub for suspension mounting points or coilover mounts. This is a huge benefit for those looking to have an aggressive off road vehicle but maintaining civility inside for driving comfort.

Rockzilla keeps your Jeep Wrangler a Jeep Wrangler and does not turn it into a swiss cheese buggy Jeep. The packaging of the Rockzilla System in the JKU is second to none.

The center skid plate gets cross ribbed for structure. Once installed, the JKU looks like it came from the factory with Rockzilla.

Turn your JKU into a Trail Monster but with Civility! Like all of our systems, amazingly tuned ride and handling is our number one priority!

It is no different with Rockzilla. Coilovers add another level of tuneability for the vehicle owner to further enhance the ride, handling and off road performance to their liking.

Install exceptional value, and be the foundation for every adventure whether it be on the Street or on the Trail with a Rock Krawler Coilover Suspension System! Thank you for considering Rock Krawler Suspension.
