Steering Gear Box - 1ASTB00018

Part Details

  • Operation: Power
  • Steering & Suspension: 2.5 Turn

  • New
Picture coming soon

This is a rebuilt power steering box. Complete lock-to-lock travel in 2.5 turns. Steering Ratio is 12:1. This power steering gear box fits most 59-76 GM cars and trucks with a conventional power steering setup (engine mounted pump and two lines to the steering box). The power steering box will not fit slave cylinder set-ups found on many early 60s Chevrolet.

This power steering gear box will improve your turning quickness and feel. You may lose some turning radius but the improvement you gain is well worth it. Easy bolt in replacement if you already have power steering. Power steering gear boxes are rebuilt from various cores so we cannot match GM part numbers. 


These steering boxes are built to order, Please allow 2-3 weeks for delivery. There is NO core charge.
