Here's the passengers-side housing. The open sides of the housing have been boxed in, and reinforcing plates were added to the outer edge of the housing. The McNeil TTB housings are designed to align using a 0-degree alignment cam with 5 inches of lift. Chad moves the lower ball joint's mounting bore to compensate for the lift. These housings pivot in the stock pivot brackets. Retaining the stock pivot points and avoiding big-inch drop brackets nets a stronger front end compared to using drop brackets. Drop brackets create extra leverage on the frame, which can fatigue the frame and cause cracking.
