thanks for the info I was looking on the web and they were talking about series 800 saginaw boxes with 13/16 input shat with 36 splines but I think that’s for power steering? So on the 525 is that out of a 60’s or 70’s Chevy? And is the number cast into the casting and are there other Saginaw boxes that will work also . Thanks

Yep Saginaw 525 you can even buy them new if your well heeled. The 6.25 turn lock to lock makes for a very nice road box not so twitchy as some of the much faster rate power boxes. Not a bad idea if your going to be off road to run a cross brace from the pitman arm housing to the frame rail on the Right. You can see what I did here:   Edited by Mark W. - 29 Oct. 2019 at 12:06am |

I prefer the Saginaw manual boxes as were standard on the 1972 through 1975 CJ's.

I’ve got a manual box from a 70 commando. Is it the same as a CJ box? A good swap candidate for a 2a? I was saving it for a possible swap in the future, but would I be better off to sell it and find a different model?

I'm currently running a 525 Saginaw box on Thumper. It does really good on the road. However, off-road I don't like it near as much. I'm currently running 33x12.5's and when aired down to 7-8 PSI it turns hard. I am actually planning on changing over to power steering this winter.
Mark, Is that support you have that crosses over to the other frame horn something you made or does someone sell that set up. I do think part of my problem is flex in the drivers frame horn. In fact, while I was n Colorado in September the front crossmember under the radiator broke loose from the frame on the drivers side due to the extra torque from the Saginaw box. That crossmember you have there would help alleviate that problem. |

Google CJ steering brace.
Lots of kits and videos available (but are fairly easy to fab) |

So what all does a guy need in addition to the 525 box if converting from the stock Ross steering set up? How involved is this conversion? Thanks!

You will need to box the left side frame horn. Fabricate or find/buy a mount, Then you will have to create a steering shaft from the Box to the original column that will have to be cut down and adapted to mate up with the new shaft. At least one if not two universal joints will be required to do this. Then it is typical to convert to a single tie road and drag link setup. Most people use a double end tierod end on the pass side. Advance Adapters has a page about the conversion they sell a kit $$$$$$$$ It would be a pretty busy weekend job to get it all done.

For closed knuckle front axle like the 25 or 27, I'd source the passenger side 2 hole steering knuckle from an early Wagoneer or like vehicle and use it.
Much stronger and each hole uses it's own tie rod end. Added leverage to a manual system. The double end most use with the single hole knuckle can be a weak link depending on usage.

I've already converted to a cross-over steering from the bell crank forward, but am contemplating replacing or rebuilding my Ross box and was interested in the Saginaw set-up as an option. It is sounding like it may be a more involved conversion than what I thought. Just figured if it was appreciably better than the Ross, it might be worth considering. Still on the fence and gathering knowledge.

I did this with mine. I found a wagoneer 27 and swapped knuckles. I never liked the single hole design.

I remember seeing yours at the FCT, Kevin - that is a really nice set up you have! But this is looking more involved than what I was originally thinking. I'm happy enough with what I have. BTW, Rict...sorry to have gotten things a bit off track here. Good luck with your conversion, let us know how it goes.

Hi, I am wondering how hard it is to adapt this 525 manual steering box to a 50 Willys pickup. And what tie rods would I use to connect it all together. Is Power steering a better option? Truck is not driver off road or in demanding conditions. Thanks in advance, David
