The Jeep Farm Frame Boxing Plates for Full-Size Jeep
The Jeep Farm is growing frame plates for FSJ.
Full-sized Jeeps have quite a following in the off-road world, and while many are pretty beefy, one area where there is room for more strength is in the frame. Our pal Drew Norman of the Jeep Farm (http://thejeepfarm.com/ and https://www.facebook.com/Thejeepfarmllc/ ) has built many Full Sized Jeeps (FSJ) over the years, and one trick he's used a time or two to help build a more bulletproof FSJ is to box the frame.
How to Box an FSJ's Frame
Boxing a Jeep's C-channel frame is an old-school trick to add beef to any old Jeep with a C-channel frame. Heck, the factory even did it on some models and in some areas (near motor mounts and spring mounts) on many frames. Boxing a frame is not that hard to do, it's just time consuming. Generally, you make templates of the inside of the framerail and then use them to cut plates of about the same thickness plate steel to weld into the open side of the C-channel. The only thing that could make this any easier is if you could buy frame plates that fit or nearly fit the profile of the inside portion of your Jeep's frame. That's the idea Norman has for 1976-1988 short-bed J-trucks and Wagoneers built between 1976 and 1991. Long-bed applications and Cherokee Chief and Laredo to come if the demand is present. Fitment on 74-76 vehicles may vary, as some early FSJs have holdover parts from before the official factory frame changes.
Jeep Farm Frame Plates
The Jeep Farm frame plates for FSJ are cut on a CNC plasma table for precise fitment out of 1/8th pickled and oiled, cold-rolled steel plate. Frame plates are dimple die'd for weight and strength where possible. Grinding and welding for final fitment are required as are clearance for fuel lines, wiring, and fuel tank mounting (although some provisions for tank mounts are present). Translation is, some fitment, fabrication, and clearly welding by the end user is required for installation. The plates are currently priced at $550 per set plus shipping.
