Rock Krawler JK55TTLA4 Triple Threat Long Arm 5.5" System for 07-17 Jeep® Wrangler Unlimited JK 4 Door

Catalog #: 16189.2023
Rock Krawler Part #: JK55TTLA4
Description
The 5.5 Triple Threat system features 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. The high clearance lower control arms are made of 2" tubular steel and use 1.25" shank Monster Krawler joints at the axle connection and a Pro Flex Joint at the frame connection for the quietest ride quality out of any suspension system on the market. This system features the best in class cross over angles and ground clearance. The rear suspension features adjustable anti-squat so you can dial in your JK's suspension to your liking. All of the high clearance lower control arms are made from 2" solid alloy steel and built for abuse. Like all other JK Long Arm Systems the rear axle has been moved back 1" to allow for greater clearance between the tire and factory sliders for Rubicon Owners. This system is completely upgradeable to coil overs and comes with our exclusive Abuse Proof Lifetime Warranty on all hard parts!
