BMR Suspension SFC004 - Manual

HARDTOP BOXED SUBFRAME CONNECTORS
Part #’s SFC001 and SFC004
NOTE: Although this installation can be performed with a hydraulic jack and stands, a drive-on 4-post service lift is recommended.
REQUIRED TOOLS:
Welder
4 Jack stands or drive-on service lift (preferable)
2 – 18mm wrenches
Sander, angle grinder, or wire wheel
Pry-bar
Ramps (optional)
INSTALLATION:
1. When installing Subframe connectors, it is recommended to perform the installation with the vehicles
suspension loaded (vehicles’ weight is resting on the suspension). A drive-on service lift is
recommended however it can also be accomplished with a pit or ramps and stands. If using a lift,
disregard this step and move on to step 2 below. Drive the front two wheels onto ramps. Lift the rear of
the vehicle and place 2 jack stands under the rear end.
2. Start with one side and remove the front bolt on the lower control arm. NOTE: DO ONE SIDE AT A
TIME; DO NOT REMOVE BOTH REAR CONTROL ARM BOLTS WITH THE REAR END
SUPPORTING THE VEHICLE.
3. Position the subframe connector over the rear control arm mount in such a way that it "sandwiches" the
subframe. Using the provided hardware, slide the bolt through the subframe connector and Subframe
and install the nut finger tight.
4. Using a jack if necessary, lift the front of the subframe connector up into place until the front mounting
plate is flush with the center of the subframe. Trace the Subframe connector mounting plates front and
rear using a permanent marker.
5. Remove the Subframe connector to prep areas for welding. Remove paint from the subframe and the
subframe connectors at the weld points using a wire wheel or sander to get bare metal. For optimal weld
penetration, it is important that all paint and powdercoat be removed from the weld areas before
welding.
6. Re-install the prepped Subframe connector and insert the rear bolt.
7. Weld a bead around all three sides of the front mounting plate and tack weld the rear mounting plates.
To prevent burning the rear control arm bushings, lower the control arm out of the mount once the rear
plates have been tack welded into place. Once the control arms are lowered out of the mount, weld as
much of the rear plates as possible.
8. Wire wheel the weld points and spray with rust preventative primer or paint.
9. Re-install control arm and tighten to 90 ft/lbs.
10. Repeat steps 2-9 on the opposite side.
