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

  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.
