Frame Sandblasted what would you do?

Just starting a new build. Last build was 20 years ago on the YJ - Chev 355/700r4/D300 with D44 axles. Picked up a southern frame 10 years ago and have been saving it until now. The engine let go last week (threw a rod), so time to get started on the new build.

The frame is all down to bare metal and I have removed the stock motor mounts.

My question is : What would you change before I go and paint it? Is there any areas I should strengthen/upgrade because now is the time.

Thanks

MegaT

Cage tie-ins so a 6 point roll cage will connect directly to the frame.

I’d cut off the panhard brackets. Redo the rear crossmember to a rectangular piece of 1/4” tube with a built-in 1-1/4” receiver and D rings (not shackle points; actual for real D rings) or tow points. Move the steering box forward a full inch as well as the rearward front spring hanger. Raise the motor mounts 2” and weld tabs for a tranny crossmember (flat skid provision).

I did a couple of those to my latest rendition of my ‘89 and regret not doing the others then.

BTW the frame rust from inside out you know, right? Use an epoxy primer- most of the YJs had a galvanized frame which sandblasting probably removed the rest of.

Thanks for the answers, all great ideas.

From Canada understand rust completely, I've had this YJ for 23 years, and a couple of XJs to boot. My goal is to do a build with, all as much as possible rust free all original panels, frame and tub. No aftermarket.

I used Mastercoat on everything inside and out....Hopefully good as long as I own it...

After you are assembled, buy 8 cans of fluid film and the $30 extension and 360* nozzle kit. Do inside the frame and up inside all the cavities up under the floor supports, rear threshold box, etc. I wouldn’t do it until you’re done cuz it’s nasty and messy

I'd also add in that maybe upgrade the front shackle hangers. I have seen a few people break them off with hard wheeling.

Good point!
You can reinforce the tops of the bushing tubes by welding a small piece of 1/4“ to it and the frame. Then it can’t flex.

I would cut all of those leaf spring hangers off and build yourself a nice linked suspension. Aside from that @fishadventure has added solid advice if you are staying with leaf springs. I suppose now would be a good time to redesign the rear shock mounts. The factory design collects crap and eventually rusts out there.

Lots of good ideas

If I ever have mine that far apart, I'd remove the front round crossmember and replace it with
a good strong dropped winch plate/Xmember, to bring the fairlead out the bumper,
protect the winch and help cooling.

Whats over that next ridge?
