Don’t need a 7075 knuckle for your 2005+ Superduty axle, but want something with double-sheer and hi-steer? These knuckles bridge the gap between a stock knuckle and our 7075 offering to bring you strength at an affordable price.

These are cast, machined, and powder coated right here in the USA without the need for machining, drilling & tapping your current knuckle.  They're stronger due to added material thicknesses/radiuses blending the body of the knuckle into the upper arm and not having material removed for a studded arm. They feature an adjustable steering stop and accept our 05+ Balljoint Delete Systems or a regular Balljoint if you so choose. 

Building an axle and don’t like how thin the aftermarket inner C’s look? Neither do we. Like the 05+ outer knuckle, our C’s are cast and machined here in the USA.

We added 1/2” to the inner side for more engagement and added webbing to tie the upper & lower potions of the knuckle into the added material. While we were at it we wanted to add a better place for shock mounting….see the flat area on the top portion of the C? These will fit a 3.5” to 4” OD tube for your needs.

These tube seals are designed and built in-house. The outer piece permanently mounts in the tube and allows the inner aluminum housing and seal setup to be removed from inside the housing. We use Seals-It seals with all of our tube seals.

These IMS Unit Bearing Cups allow for the use of 05+ Superduty unit bearings on your straight axle build. Cups and unit bearings eliminate traditional spindle and hub set-ups and allow for 40 spline axle shafts.

Cups come in 3.5” and 4.0” bores. Additional sizes can be made upon request.
