Rock Krawler JK 3.5 Triple Threat Long Arm System


 Product Description

Rock Krawler is proud to bring you the JK 3.5 Triple Threat Suspension System. The Triple Threat Systems are the most versatile systems ever made for Wrangler JK’s! These systems feature a front end design that can function as a full 4 link for high speed fun in the sand or the extremely flexy independent 3 link for extreme trail use! The best part is you get to choose! All Rock Krawler upper control arms are full length! No short or mid length upper control arms with compromised geometry. Our geometry is perfect in every way. Our high clearance lower control arms are made of 2” solid alloy steel and use 1” shank Monster Krawler joints at the axle connection and the industry’s largest bushing at the frame connection for the quietest ride quality out of any suspension system on the market. We have even included a new heavy duty passenger side axle mount made of 1” thick alloy steel and 2 build a ball joints for the upper control arm pivots at the axle. No need to worry about wearing out the stock front upper control arm axle bushings since they have been replaced! The rear features our tried and true independant three link with adjustable anti-squat so you can tune your JK for your off-road pleasure. We provide you with even the little things such as rear shock relocation brackets that move the rear shocks up 2” for better ground clearance and front spring retainer clips so your front coils springs do not fall out under high articulation. All of our new long arm mounts and rear axle truss are made from 1/4" thick laser cut steel! All mounting brackets either bolt in place or come with fixtures so placement is perfect prior to welding them on. Simply put, we feel this is the strongest, most versatile and most capable 3.5 inch long arm system ever made for Wrangler JK's. Rock Krawler also backs that up with our Abuse Proof Lifetime Guarantee on all hard parts!
