Item Description

Application: Jeep© JK Wrangler (2 Door) & Wrangler Unlimited (4 Door)

Part# JK-611

The Mountain Goat Series™ fixed length front upper control arms for the Jeep© JK Wrangler allow for maximum suspension articulation. Our fixed length front upper control arms are compatible with virtually any suspension system, from bone stock up to 3" of lift. For suspension lifts of 3" or more we recommend our Part# JK-615 adjustable length front upper control arms. These can be used on up to a 4.5" lift if used in conjuntion with our Part# JK-210 front control arms geometry correction relocation brackets.

Our fixed length front upper control arms are manufactured from high strength 1.50" 4130N chrome moly DOM tubing and feature 100% TIG welded construction. They feature a CNC laser cut and formed 1/4" steel front housing bushing mounting bracket with an integral formed top gusset and a CNC laser cut 3/16" steel gusset between the front mounting bracket and the tube for maximum strength and durability. A brilliant and durable powder coated finish in your choice of bright red or gloss black provides excellent protection from corrosion, rocks and debris.

The rearward ends of our fixed length front upper control arms for the Jeep© JK Wrangler feature greaseable and rebuildable Del-Sphere™ pivot joints. These were chosen to provide maximum suspension articulation (30 degrees) and off-road performance while minimizing the transfer of road noise and vibrations on the street. The Del-Sphere™ pivot joints are smooth, long lasting and quiet.

Our Del-Sphere™ pivot joint ends feature a heavy duty 0.200" wall DOM cartridge that houses self lubricating Delrin© bushing cups, a precision ground and hard chrome plated 52100 heat treated bearing steel spherical ball, a heat treated and zinc plated retainer washer and snap ring, a heat treated and zinc plated chrome moly threaded adjuster ring and an external grease fitting. They are reinforced with 100% TIG welded CNC laser cut and formed 3/16" steel gussets. Since Delrin© is self lubricating there is no need to grease this joint which attracts grit and grime, but we do have a grease fitting in place for those who want it.

The Del-Sphere™ pivot joint ends used on these control arms are designed specifically for the Jeep© JK Wrangler application. The cartridges are only 1.50" wide and use high misalignment spacers on each side of the spherical ball which allows the pivot joint to reach its full articulation range without the housing bottoming out and binding inside of the control arm mounts. This provides for quiet operation and a true full 30 degrees of unrestricted suspension articulation.

Our Del-Sphere™ pivot joint ends are fully rebuildable and adjustable. You can completely disassemble the Del-Sphere™ pivot joint for cleaning, inspection, etc. You can also adjust the amount of friction on the spherical ball, the amount of tension can be easily adjusted by using our optional adjustment tool to tighten or loosen the threaded adjuster ring. The threaded adjuster ring is then locked in place by a set screw.

What that means is if over time, miles and abuse the tolerances open up you can simply tighten down the threaded adjuster ring and have your pivot joint as tight as it was the day it was brand new. We doubt you'll ever need to replace the Delrin© bushing cups, but they certainly can be. Unlike a rubber bushing or spherical rod end, the Del-Sphere™ pivot joints are 100% rebuildable at a very low cost.
