 Tack-Weld Saddle Brackets: Once you are sure the rear end is located properly, tack-weld the saddle

welding.

 Panhard bar: Secure the panhard 

bar to the rear crossmember using the 

supplied 5/8”-18 x 6” bolt and lock nut. Adjust the 

panhard bar so that there is about ½” of thread showing 

and tighten the jam nut. This will allow for a small amount 

of adjustment in both directions. Now, raise the panhard 

bar bracket into place on the rear end and bolt the panhard 

bar to it using the 5/8”-18 x 3-1/2” bolt and lock nut. Rotate, 

or “clock” the bracket on the rear end so that the bolt is 

horizontal. Double check that the bracket is in the proper 

position and tack weld the bracket to the rear end housing.

 As shown, the panhard bar bracket should be about 17 ½” from 

the center of the housing. The center of the housing can be found by 

measuring the flange to flange distance and dividing by two. 

DO NOT assume that the drain plug or third member are centered, 

this is often not the case. You must measure to find the center! 

NOTE: 

There are 3 possible locations for each end of the panhard bar, 

use the mounting holes that make the panhard bar level with the ground 

at ride height. This will vary depending on ride height.
