BOXED SUBFRAME CONNECTORS – 2005 MUSTANG

Part # SFC011

NOTE: Although this installation can be performed with a hydraulic jack and stands, a drive-on 4-post service lift is
recommended.

1. Lift vehicle and support. If you are not using a drive-on lift, the vehicle must be

supported with the suspension loaded. This can be accomplished by driving the
front wheels onto ramps and then placing the rear axle on jack stands.

2. Using a 10mm socket, remove both rear parking brake cable brackets as shown in

Image 1.

3. Using the same socket, remove the plastic fuel line cover on the driver’s side.

4. Using a 13mm socket, remove both deflectors located in Image 2.

5. Starting with the passenger’s side, lift the sub frame connector into place and

support.

6. Using a marker, trace all weld surfaces then remove sub frame

connector.

7. Sand or grind all weld areas at the trace points. Also remove the

powdercoat at all weld points.

8. Reposition the sub frame connector into place. Verify that all

mounting surfaces of the sub frame connector are flush with the sub
frame and support it in place. Tack weld all mounting points before
any full weld beads are performed. Once all mounting points have
been tack welded into place, remove the supports and weld every
connection possible.

9. Repeat steps 5-7 for the driver’s side.

10. Before welding, insulate the plastic fuel lines near the front of the

sub frame connector with a damp rag or section of leather welding cloth. Proceed with the weld procedure listed in step 8.

11. Prep and paint all welded surfaces with a rust preventative

paint.

12. It is necessary to section the plastic fuel line cover in order

to reinstall it. This can be done with a jigsaw, band saw,
or with tin snips. Cut at the points shown in Image 4 and
discard the center section of the cover, the removed section
of the cover will now be protected by the sub frame
connector. Reinstall the two sections of the cover.

13. Install the rear parking brake cable brackets over the studs

located on the rear of the sub frame connectors and tighten.

14. Lower the vehicle.
