This control arm kit from SSM Performance is designed to bolt an Ford Explorer rear end into GM A-Body, this includes Chevelle, GTO, Monte Carlo, Malibu, El Camino, Regal, Grand National, Grand Prix and Cutlass and many others. These upper control arms are built at the correct angle and length to attach to the the truss and chassis. The relocation bracket kit will allow for proper instant center (geometry) changes.

Common questions...

Q. What years of Explorer do I look for?
A. 1991-2001. Earlier models have drum brakes and later have disks.

Q. Do I need to narrow the rearend to fit.
A. NO.

Q. Does the rear need to be centered?
NO. The u-joint will work at the slight angle with no issues.

Q. How wide is the Explorer 8.8"?
A. The 8.8 will be a bit wider than stock. 3/4" each side. Stock 7.5" is 58" and the Explorer 8.8" is 59.5".

Q. What wheel and backspacing is needed?
A. 4.5 BS on 8" and 5.5" on 9". The Explorer rear will give you 6-3/8" clearance between the frame rail and the wheel mounting surface.

Q. Do I need to redrill my axles and rotors?
A. No. Just use a Ford pattern wheel to keep cost down.

Q. Will I need to shorten my driveshaft.
A. NO. You will need to replace the rear u-joint.

Q. Can I still run tailpipes with the truss kit?
A. Yes, we have used 2-1/2" and 3" tailpipes with this.


How much power can the truss take? Unlike the common trusses that you see on the market that have only one piece of bent steel that has to be tied into the differential cover to make it suitable for use, our trusses have a 1/4" main hoop structure and then have two 3/16" boxed gussets all of which is made from 100,000 min yield steel to make them incredibly strong. You will also notice that the boxed gussets are narrower than the main hoop. We did this so that you will have no butt welds but have the stronger T weld. We intentionally do not have unnecessary material added to the top of the truss. Our truss top plate is made from 1/2" and if you add more material to the top it just makes it hard to achieve the proper instant center geometry. We have tested the model in Solid Works Simulation Professional (computer load testing program) and real world test and feel this is the way to go. The addition of the welded boxed 3/16 Gussets increases the welding surface area of the truss on your axle tubes to distribute the loads that your axle will encounter. With the increased foot print of our trusses they will also add structural rigidity to your axle and help prevent your axle from bending and warping. This truss system was designed with a state of the art 3D CAD software and plasma cut on a cnc table. Like all of our products our trusses are made from high-strength American steel. If you shop around you will find that our truss systems are the best product for your four and three link suspension needs. Completely over built for automotive applications, as are our control arms. They have been tested at 1500 HP and 1300 lbs of torque (540 BBC 12 PSI on methanol), If you are making more than that I would suggest going to a tube chassis or let us build you something to better suit your needs.
