PLEASE READ THESE DIRECTIONS THROUGHLY BEFORE BEGINNING INSTALLATION

All that is required are a few careful measurements to locate the crossmember and upper spring mount correctly on your chassis before welding into position. Minor Trimmings may be necessary for some variations in the frame. We recommend that all the welding should be done by a qualified welder using the proper techniques. We also recommend that the initial  and subsequent wheel alignment should be done by a qualified alignment shop. If you have any questions, please don’t hesitate to call us for assistance at 1-800-979-4278.

1. PREPARING THE FRAME

• Mark the original location of the axle centerline on the frame
• Remove all of the old suspension pieces by unbolting the whole crossmember along with the control arms and spindles attached.
• Clean the frame of any dirt and rust, especially around the bolt holes where the original front crossmember bolts on and where the spring mounts are to be welded.

2. INSTALLING THE CROSSMEMBER

• Position the crossmember under the frame with the studs going into the bolt holes (hole#3 and hole #5) for the original crossmember (figure #2).
• Install the nuts to the four studs and tighten snugly.
• Install the bolts and nuts into the 6 remaining holes of the frame (hole #1,2,4) and tighten evenly, the center of the crossmember should be at the axles centerline mark on the frame.
• Due to the variation in frames, some holes need to be aligned or enlarged with a 3/8” drill.
• Mark and drill the frame (3/8”) for holes #6 and #7 on the rearmost part of the crossmember to the frame as shown on fig #2. Use the crossmember as a guide.
• Install the remaining bolt and nuts into these holes and tighten all bolts and nuts.
• If you are using the T.C.I tubular lower control arms:

          A. Drill the lower control arm holes in the crossmember to 5/8”.                                                                  

          B. Position the lower arm spacer (part #11) on the rear side of the crossmember, through the elliptical hole,in            the crossmember gusset (using the lower control mounting bolt through the crossmember as an alignmentguide).         See figure #3.                                                                                                   

         C. Weld on the spacer to the rear part of the crossmember (on the elliptical hole).

3. INSTALLING SPRING MOUNTS

·         Position the spring mounts on the top, outside edges of the frame rails, with its centers directly over the center of the lower crossmember and axle centerline. (figure #4).

·         The distance between the middle of upper control arm adjusting slots should be around 29”. Adjust the hats in or out of the frame by trimming or adding shim where the hat meets the sides of the frame.

·         To determine the left and right sides, the spring mounts should sit slightly lower in the rear to maintain the proper antidive geometry.

·         Tack both spring mounts in place, double check your measurements (including diagonally for squareness).

·         Mock up the upper control arm, lower control arm and the spindles, raise or lower the spindles until the lower control arm is horizontal to the ground and check the wheel camber. Make sure there is enough adjustment to set the spindle at 0 degrees camber.

·         Final weld spring mounts to the frame on both sides.

4.COMPONENTS ASSEMBLY

• Install the lower control arms a strut rods, If applicable, into the crossmember. Install tubular lower control arms with the short spacer (part #12) position inside the crossmember. The shock bolts should face the rear of the car.
• Install the upper control arms, with the serrated side of the cross shaft facing down, using the special button head bolt, FORD #385713-S-101.
• Install the coil springs and spindles, with the steering arms toward the front side.
• Install brake rotors, calipers and brackets, rack & pinion steering unit, and shock absorbers.

5. SUSPENSION ALIGNMENT

• Set ride height so the lower control arms are horizontal to the ground and align the wheel with the following specifications:
• Camber at 0 degrees
• Caster at 1 degree
• Toe in at 1/16”
