Sigma Motorsports

Jim came to us with a few needed modifications, but once we started into his rig, the list just kept getting longer; cage redo with seats tied in, new PRP seats, cage tied to frame with custom built sliders, rocker protection, rear bumper, custom skid/cross member to accommodate Atlas/700r4, etc. All finished off with a thick coat of hammered paint & satin black interior, the rig came out nice. Click the pics for detailed shots of some of the stages of this build.


	Shot as it came to us. In this shot you can see some of the rocker damage as well as the ill-fitting rear cage setup. Next shot is the small block 400 being pulled for a freshening while we do the rest of the work. SM420 pulled at this time as well as the D300 to make room for design of the new crossmember for the 700R4 and Atlas.


	In the first image, we can see the rocker damage sustained without any kind of sliders or rocker guards. We fabricated a set of custom sliders, all from 3/6 rect. tubing and 1/4" plate. The sliders are welded directly to the frame, and are also supported by the tie-ins to the cage.


	In these two shots we can see where the sliders tie into the A and B pillar of the roll cage. In this system the tub is sandwiched between the slider plate and the foot plate of the roll cage, bolted together with 1/2" hardware. This system provides a frame mounted roll cage, while stiffening the entire jeep and offering strong rocker protection.


	Rear bumper built from 3/16" 2x5 rect. tubing. Utilizes a threaded plate mount system with frame tie-ins for extra strength. Weld-thru shackle mounts provide an excellent extraction point.


	The cage got some love in the form of a redone back half, as well as new bracing, handles, dash bar, and tied in seat mounts for new PRP's. Cage was pulled for weld and paint to guarantee complete coverage.


	The inteorior was stripped, cleaned, scuffed and sprayed satin black to make the cage and copper paint pop. Cage was dropped back in, and new PRP seats installed. Perfect color combination.


	To further reinforce the rocker area (and hide the unfortunate trail damage) we covered the area with 1/4" plate front to rear. Bolted on with 3/8" grade 8 hardware, it's not going anywhere. Gives the rig a nice finished look on the outside and ties it all together.


	To finsh things up, we built a crossmember/skidplate to protect the vulneralbe 700r4 pan as well as carry the Atlas. All plate is 1/4" and it is hung at all 4 corners by 3/8" thick tabs.


	The freshened up small block 400 was dropped back into it's place, and we called this job done. You can view the entire gallery of pics HERE. Please feel free to email us if you have any questions or comments.
