Thanks to your direct feedback and input here on JK-Forum.com, Dynatrac has developed their all new ‘Unlimited’ ProRock 44 axle housing and will be offering it to our members at an introductory special price until August 13, 2010 – 5PM PST:
Our ProRock 44 has been a very popular upgrade for Jeep JK’s, but owners have been asking us for even more. We’ve listened, and we’ve got a brand new option – Introducing the Unlimited ProRock 44!!
The owners of some Jeep JKs have discovered that lifted rigs need a bit more pinion rise to minimize the possibility of drive shaft vibration. However, changing the pinion angle on a front axle housing, affects the caster angles which are important for handling and steering. Therefore, there is a practical limit to increasing the pinion angle adjustment.
Our new Unlimited ProRock 44 is built to allow an increased pinion angle but retains or even increases factory caster angles. This helps prevent drive shaft vibrations and can improve on-road handling substantially. It also helps get the drive shaft moved up and out of the rocks. We’ve also moved the shock mounts outboard slightly to help prevent the shocks from rubbing on the frame under full articulation, and make it easier to utilize some of the new, big body shock absorbers.
• Over 2 ½ times as strong as a factory Jeep housing!! Over twice as strong as most sleeved and welded housings.
• Suspension Brackets are 50% thicker and much stronger than stock
• Equipped with Dynatrac’s own heavy-duty end forgings (aka C’s) – Some areas are over 180% thicker than stock- No gussets needed
• Brackets and mounts designed and located for lifted Jeeps (Unlimited housing)
• Made in the USA!!
