Install the Front Crossmember

A photo is not available for this step because it’s very easy to do. Locate the 3/4″ x 4.5″ bolts, nuts, and washers supplied with the kit. Bolt the crossmember in place through the factory front lower control arm cam bolt holes. Leave it loose.

At the top of the crossmember where it meets the frame, there will be two holes that face upward. You’ll need to bolt the crossmember to the frame with the supplied 1/2″ x 5.5″ bolts, locknuts, and washers. Pay attention to the next step because one of these bolts will also be used to secure the power steering lines.

18bLocate the 1/2″ x 5.5″ bolts, locknuts, and washers AND a single 1/2″ short nut (yellow arrow).

On the driver side you will need to insert the 1/2″ x 5.5″ bolt upward so the head points down and the threads point up and screw the 1/2″ short nut onto it – not the locknut! Leave it loose.


You may as well install the passenger side bolt heads down and threads up so it matches, but on the passenger side use a locknut – not a short nut. Leave it loose as well.

IMPORTANT: If I were to install this kit again, then I would buy a 1/2″ x 6″ bolt for the driver side. The reason is because the locknut will eventually be stacked on top of the short nut in order to secure a power steering line bracket in place. The 5.5″ bolt that Fabtech supplies is not long enough for all the threads on the two nuts that will be bolted to it!

Connect the front differential brackets to the Fabtech front crossmember using the supplied 9/16″ x 3″ nuts, bolts, and washers. Reconnect the electric, vacuum, and breather lines to the front differential.

Note: You may need to buy a longer piece of hose for the differential breather line. I have to because mine is about 1″ short of even being able to make contact with the differential. I know it will only cost about $1 or less to buy this part, but it is definitely something Fabtech should have included with the kit!
