Speedway Motors 91032277 Details

This Saginaw manual steering box fits many GM applications from 1965-1991 and probably many more. It accepts either our universal pitman arm (702-2940) or your stock GM arm (small style, like our 910-32552). Box has a 25:1 ratio (6.25 turns lock-to-lock) with a 3-13/16" long input shaft with 3/4" 30-splines.

  • Input shaft is 3/4"-30 spline
  • 6.25 turns lock to lock
  • 25:1 ratio
  • If you turn the input clockwise, the output also turns clockwise.
  • Stock specifications on this gear refer to it as 6 rounds lock to lock for a 24:1 ratio.
  • 36 Spline
  • 1.058 Diameter Top of Splines
  • 1.100 Diameter Middle of Splines
  • 1.124 Diameter Bottom of Splines

Note: Steering box is not adjusted at the factory and therefore, it is necessary that the steering box be adjusted upon installation per the instructions as provided on the PDF instruction sheet.

  • 916-32005 Model T-1934 Ford Frame - Steering Box Mount

Needed to replace 1st one, but new one g

I ordered/installed this product over a year ago. I had some play in the steering. Tried a couple things to tighten and loosen the play. When that failed, I called Speedway customer service, they sent me a shipping label so I could ship it back for FREE and they shipped me a new one, no further charges. That was awesome of Speedway. The new installation works just great. Im 100% satisfied now.

Waiting For Replacement

This one went on a 1976 Toyota Landcruiser and is a swap I have done a few times on 4x4s with great results. BUT...The gear box I got from Speedway had so much slop in it I thought maybe they'd sent me a core by accident, but the nice people (no irony) at Spreedway said they don't take cores. Anyway, I see my experience isn't unique to Speedway customers and I'm waiting on a replacement box. I have to give them credit for being easy to work with, but as this seems to be a recurring problem--and as yanking the box off and replacing it is a P.I.T.A.--it seems Speeedway would find a better supplier. Will be interested to see if the next box I get from them is any better.

This is replacing the first new one I bought from Speedway that wore out in under 44,000 miles. It can not be adjusted anymore. One half a turn before the wheels even start moving.

Good price and product

Building a '56 Chevy gasser, no inner fenders, and fenderwell headers, using aftermarket tilt column from Speedway. Is this the right box? Also would I need a drop pitman arm or would the box sit low enough?
