Steering Gear for ‘87 2.5

[Porquer]

I have an ‘87 Sportruck that came from the factory without power steering. I’d like to add power steering, and I’m wondering what steering gears from which vehicles will be compatible? TIA

It is just a Saginaw box, so a lot of vehicles had boxes that would bolt in. Are you just looking for a stock replacement box or are you wanting something more performance oriented?

Stock should be adequate. I'm on 30s and drive it on the street 90% of the time.

My understanding is a later ZJ steering box can be a nice upgrade as they are faster compared to what came in an MJ.

I did the same with my 87 Sportruck. I started out by adding a p/s box from an 86 Comanche, because that's what I had, but later installed a ZJ box. It has a quicker ratio. Lock to lock from the 86 p/s box to the ZJ box went from 3 1/2 turns lock to lock, to 2 1/2 turns. There is a connector already in your engine bay harness for the p/s pressure switch. It's plug and play. It will turn up the idle when it sees pressure too high. Beyond that the 87 2.5 had a remote reservoir pump, that at the time I did mine the reservoir was unobtainable. I do have to say though, that adding p/s is the best upgrade I've ever done.
