Rock Krawler 2.5" Starter System Suspension System for Jeep Wrangler JKU
The Rock Krawler 2.5" Starter System is the introduction to a what could evolve into a full RK Suspension system. This kit gives you the minimum you must have in geometry correction when adding taller lift springs for your Wrangler. You will experience an excellent highway/around the town ride due to our triple rate coils. You will have enough coil length to flex out on a trail without unseating a coil spring. To support the extra travel, stainless steel brake line drop brackets are also included. The fixed high clearance front lower control arms will correct the caster and front axle position for proper drive-ability. Coil spring bow is also addressed in this Starter System at a very friendly budgeted price. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street or down a Trail! Rock Krawler Suspension is the best place to start your Wrangler build.
