I have heard that there is a great article in Circle Track on installing a roll cage. However I do not have that article. I am looking for a website that may have some info on how to.

Any suggestions?

Steve Smith Autosports sell some great books. You can probably find him on the net but i do know his order forms are in CT and SCR. Eddie

Some basic tips. Red Line sells good cage kits -- we stumbled across one at a swapmeet, with bars for front loop & rear kickers) for $150 (probably retailed for almost $300). Fits perfect -- like a puzzle.

If you are running a full frame and if the following is at all possible, cut or torch a hole through the top of the frame and tack the four main post tubes to the bottom of the frame (you might have to cut a little flap to access it).

It makes it more difficult but your cage will be safer -- not to mention it will help unify the frame & cage more.

Deak,

That was our general plan. I just wanted to see if I could find an article somewhere that was titled, Dirt track roll cage installation for Dummies.

Thanks

You don't need an article. Go to rlms they sell the best kit for the buck. I bought one for my car. 340 is was the best kit they had. I love it. Get some extra tube for tieing the rl to the fr. I can't say info about the quality of the kit. Save the money on the steve smith books put it towards the kit. Also look at some of the cars around its pretty basic.

Thx frank,
But I already have the cage. I was given a used one that needed some bars replaced. That part is done.

Just trying to get a broad range of opinions.

Something to maybe try ....

We had a bar put in that I haven't seen too many other folks doing. It ended up being around 6 feet long (can't remember exactly).

It ran from the center of the "X" brace (behind and to the right of the driver seat), down diagonally and to the right, through the firewall, and onto the frame a few inches behind the upper A-arm on the right side.

My old man (who knows more about this stuff than I could ever pretend to know) ran that for decades on his old LM tanks in the 60s and 70s. He tells me it is a big help in tying the frame and cage together and, with rear kickers as far back as they can be put, it really strengthens the frame and cuts down on flex. I take his word for it, but it looks like it'll really do the trick. Just another idea to kick around. Best of luck to ya ....

if the cage is already together isn't to much you can do other than make sure the cage legs and frame are preped real good cut the roof off with a sawzall and burn it in

Racer,

That is what I looking for. Ideas, tips, tricks on installation.

I have seen a few different configurations.

The best as far as stability looks like cutting a hole in the top of the frame and welding two pieces of flat stock on the underside of the top of the frame and on the bottom around the leg.

I might know the article, is it the one from earlier this year that details some tweaking of the frame to achieve better forward bite?
I don't have the article but talked to a friend about it recently. I would try emailing or calling Circle track and let them know what you want. they have extra copies of the article and magizine.

THE BAR DEAK IS TALKING ABOUT IS CALLED A PETTY BAR.

AND THE ARTICLE WAS A JOKE, THEY JUST PLAIN JACKED UP THE CAR AND PUT IT ON JACK STANDS WITH A 1.5 SPACER ON THE LF JACKSTAND. THEY ALSO FITTED THEIR CAGE FIRST AND HAD TO COBBLE IT UP TO FIT THE NOW TWISTED CHASSIS.

THEY ALSO ROLLED THE CAGE AROUND ON THE SHOP FLOOR TO WELD IT ALL THEN PUT IT IN, GUESS THEY DONT CARE IF ITS SQUARE WHATSOEVER.

1. DONT CUT YOUR ROOF OFF.

2. PUT IN THE REAR HOOP AND HALO BAR AT THE ANGLE AND LOCATION YOU WANT AND TACK THEM TOGETHER.

3. PULL THEM OUT TACKED TOGETHER AND FINISH WELD THOSE 2 JTS.

4. REINSTALL THE NOW WELDED HALO AND REAR UPRIGHT HOOP IN THE CAR, THESE ARE THE ONLY 2 JTS YOU WOULD HAVE HAD TROUBLE WELDING WITH THE ROOF ON.

MAKE SURE YOU PUT THEM BACK AT THE SAME ANGLE.

I thought a petty bar, is the bar that runs to the top right corner of the halo bar.
Richard Petty first installed this bar to support the front passenger window corner because in a roll over he said this was the first part to hit. And if that didn't collapse the rest of the roof may say supported.

66 the cage is already put together they have to cut the roof off or cut the cage up.but i do agree if your building a new cage no need to cut the roof off ,i don't like the idea of cutting into the frame either just makes it that much more of a pain don't think about it on a used cage consider this they cut it out of an old car so unless they cut it with a torch around the frame and the weld is still there then it's been cut above the origanal weld so it's already shorter than it should be then if you go and cut a whole in the frame and stick it in there thats going to be even shorter you'll end up to the point that you can see day light between the cage and roof

when they cut my cage out of the other car they cut the tubing and not the frame on 2 of the 4 posts, so they ended up being too short. i had to cut a pipe that would slide over the post and adjust to the right height then weld it in. cutting the roof off aint that big of a deal, welding it back on ***** though. all i got is a stick welder so you know how much fun i had, lol. gould

I can't imagine having to do that with a stick welder.....lol....as far as cutting the top off, if you do, try to cut it low, where it meets the body, on some older cars the factory used lead filler to smooth things out, and you'll have to melt it off before you can weld it back, and then because there's such a deep gap where the lead has been taken out you'll have to use filler to smooth it back out again.

We always called it a Bay Bar. It runs from the right front frame horn to the X-brace hehind the seat and then to the rear frame.
