BEFORE YOU BUY THIS.
Save time and headache when trying to build your own notch with our kit.
We can CNC cut this in any thickness material you need. You will need to contact the shop for the other sizes.
CNC cut to fit all G Body frames. Made from Premium Grade 1/8″ (.120″) Pickled and oiled steel (HRPO).
This comes with both right and left frame sections and ends to bridge the gap from the notch.
This is thicker and stronger than the factory frame.
This kit requires metal fab experience and can be done in the garage with a decent welder.
Will need a welder, hammer, die grinder and a bench vice.
Due to the Lack of consistency with the G Body frame over the years some minor trimming and will be necessary.
Application:
1978 – 1988 Chevrolet Monte Carlo, Malibu, El Camino
1978 – 1988 Buick Regal, Grand National
1978 – 1988 Pontiac Grand Prix, LeMans
1978 – 1988 Oldsmobile Cutlass
(1) Raise car to a comfortable working height using the method of your choice. Follow applicable safety procedures.
(2) Locate the existing rear frame that will be sliced and re-boxed
(3) SSM Performance suggests marking the length of your cut based on the wheel you are trying to accommodate. Mark a long enough frame section to allow your wheel proper clearance.
(4) The depth of the notch is also dependent on the desired wheel clearance. As a good starting point, SSM suggests slicing the frame flush with the inner fender.
(5) Keep in mind it is always best to cut less to begin with and grind to exact fit rather than trying to cut to exact dimensions.
(6) Use a vise and a hammer to bend the four smaller frame plates until they match the shape of the notch ends. Tack weld small plates into place.
(7) In preparation for welding, trim the large plates so they slightly overlap the small end plates.
(8) Before welding the large main plates, clamp them into place and check for good seams to place weld bead. The plate is slightly oversized to allow proper fit to all 78-88 G-body frames. Grind large plate for perfect fit.
(9) First, properly clean the existing frame of dirt and rust to expose bare metal for the welding process. Weld small end plates in place first, and then weld the larger plates.
(10) Installation is complete.
