Jeepster frames

Im looking into buying a jeepster. Are the front part of the frames the same width as a cj? I like the look of the full width kits and want to run them on a jeepster. Thanks for any help

They are the same, but the problem is the full width kits are made for '76 and up CJ frames. The '75 and older are the same width, but there are enough differences like the front crossmember and steering box mounting that the full width kits are only for '76 and up.

The Jeepster frames are the same as '75 and older CJ frames.

All CJ's and C101's have spring/frame width ceter to center of 27.5". C101's used a longer then CJ, non centered center bolt (spring) to soften the ride.
You need to reinforce the frame rails, I would recommend an after market steering box mount and get resourceful and build your own spring outboarding kit.

It was already said and confirmed that they are the same width.

You missed the part about the other differences. Go ahead and try to install a PSC or BlueTorch outboard kit for a '76 and up CJ onto a '75 and older frame. It will take enough modification that you're better off building your own.

You also didn't just "bolt it on".

Like I said, it takes some modification to make them work. I did a comparison with one of the first outboard kits PSC made on both years of frames. Not just flappin my lips.

The front of a jeepster is like a cj but the frame is that narrow all the way back so the rear springs are way out boarded stock....

I would put a jeepster body on a cj or wagoneer frame before I would consider another jeepster frame.

I had to notch my frame for a atlas and thats after moving my motor to the left 1.5 inches. Now I barely have room to sneak the exhaust by on the drivers side inside the frame... very narrow.

Not sure why you quoted my statement about full width kits for this, but whatever. The front of a Jeepster is like the front of a '75 and older CJ, BTW. There ARE differences other than width on '76 and up CJ's.

CJ frames are also narrow all the way back if they are '75 and older (as already said in this thread).

It's also been said that Jeepster frame rails are identical to CJ6 frame rails. This is true. My '63 CJ6 has a '73 Commando frame under it with CJ body mounts added to it. I did this because the CJ frame rail is only boxed in the engine compartment area and this also gave me more room for a V8 using the '72 and up CJ fenders. I'm fairly aware of the similarities and differences between Jeepster/Commando/CJ frames.

Anyone have experienceinstalling a 4.3, 4l60e, 241 case in a 72 commando? Need ideas on;
Exhaust manifold for driverside to keep inside frame?

Notching frame to fit 241?

Front driveshaft clearance to trans pan? Trans case is offset to pasenger side and running narrow track axles.

If you put the motor in at a slight angle the NP241 will fit the stock clocking if you want in flat you will have to cut the frame, Also CJ's where done this way from the factory.

If I was to do it over I would buy new rails and build my frame. Some have just widen the stock frame, some have built their own frames.

If you want I sell my frame to someone itís a70 frame with all holes and seams welded up plated top & bottom with a PSC shackle reversal HD CJ steering mount, boxed on rear sections of the frame and HD 2x4 front and rear cossmembers. Added 300 pound to the frame No cancer in frame and sandblasted.
I have 2k invested in the frame. A new frame is about 2800 to 3k plus shipping.

Thanks Yoda55. Pass on the frame offer. Have a very clean one ( almost hate to cut it) and want to keep a stock look - narrow track axles.

The narrow track front axle is a passenger drop axle. The 241 tcase is for drivers drop front axles.

I had to notch my frame to fit the atlas in there.

I kept it as small as I could by notching where it will be when bolted up. I put the atlas on the back of the trans output and slide it in then turn it up into the notch.

I was pretty bummed I couldnt get it up in there higher for less hang below the frame. It ended up about the same as my dana 20 stock hung down.

Youll have to notch the frame and it will STILL hang down.

Mines below the frame 3 inches or so. The only way to flat skid it would be to put a complete dog leg in the frame all the way around the Atlas.

If youve got stock exh manifolds you can move your motor over to the left 1.5-2 inches and that would help a lot. I looked at that as a solution for a long time before deciding to just put it in. Ive got headers and they are tight to the frame on each side.

Also I have stock floor and had to cut a lot of it to clear the atlas.

Old thread resurrection-

Toying with the idea of stretching an existing YJ frame that I have and plopping a Jeepster body on top. The frame is already set up for full widths, front axle is moved forward 3 inches, has motor mounts for an LQ9, and I know my atlas will fit between the rails.

Am I missing something? Any reason why more people don't do a swap like this?
