Info

This is Garage Sale priced because it has been mocked up and returned.  It will need to be adjusted for its application.

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 facotry and therefore, it is necessary that the steering box be adjusted upon installation per the instructions as provided on the PDF instruction sheet.

Notes

  1. This box can fit a lot of GM cars, plus it can work in a variety of street rod applications. When mounted behind the axle with the pitman arm forward, it steers like a Vega box. In many GM cars, it is mounted in front of the front suspension, with the pitman arm to the rear. Works well on vehicles weighing over 2500 lbs.

Notes

Top mount hole center to front of box=1.88", lower front mount hole center to front of box=2.50", lower rear mount hole center to front of box=5.38", lower mount hole to hole center=2.81"

NO WARRANTY, NO RETURNS ON GARAGE SALE ITEMS
