7075 X3 Front Double Shear Capped Knuckle - ZRP Pro Series


We have added a threaded cap to our double shear front knuckles for additional pressout strength. Our capped knuckles have been Lab tested to 86,000 lbs over the factory 17,000 lbs.

Our double shear front knuckles will ONLY work with a 7/8 uniball, or rod end. These will NOT work with standard balljoint a arms.

Our knuckles are machined in-house from USA 7075 billet aluminum.
