4runner Rear Shackle Through Frame Jig
This jig helps mark holes for cutting through your frame to install a shackle mount on 3rd Gen 4Runners. This jig will fit between the body mount on your 4Runner once the small but of webbing is cut away from the body mount. This is where a set of 63" springs generanlly land. Though this jig can be used anywhere on the frame.
There are 2 width options. Standard width, just the width of the fram with no added plate to either side.
Or Plus 1/4" for the width of a bumper bracket or other plating that you may have perminently secured to the frame.
Ships flat and will need to be put in a vise and bent, which can be done easily by hand.
