The YJ Trail Runner System is perfect for those looking to get the most out of your Wrangler. The wheelbase is stretched to 102". This is accomplished by an approximate 2" front stretch and 6" rear stretch greatly improving approach and departure angles. This wheel base, combined with the multi link design and tuned coilovers, makes your YJ great for just about all off-road conditions as well as street use. The sport tuned 14" travel front and rear 2 5/8 RRD Racing Coilovers provide great on road ride and off-road performance. Like all of our RRD products, they are full adjustable and tunable. The rear coil overs are frenched into the frame ahead of the axle enhancing the off-road ability even further, much like an off-road race vehicle! The approximate lift height supplied is 4.5" over stock and is adjustable of course. Please make sure to review the requirements for the system and proper fitment before purchasing in the notes below.
