Part #2854. Fits most 1977 - 1979 Chevy and GMC Pickups, Suburban's and Blazers 2WD. If your steering gear has a sector (output) shaft that the pitman arm is held on with a nut and washer then you have the 2WD steering gear, our Part number 2854.  This is the gear you want to use when doing a crossover steering upgrade on a 4WD truck of the same years. If you have a 4WD vehicle or your pitman arm is a clamp style the you need part number RH-2855.

This gear comes stock as the 15:1 ratio (3 to 3.5 turns lock to lock). If you would the 18:1 ratio (4 - 4.5 turns lock to lock) please order 2854 4T.

Red-Head offers a porting option for those that are either already running a hydraulic assist steering, or plan to in the future. If you choose to make this upgrade to the box (from the drop down menu), your gear box will come with two pre-drilled and tapped ports with plugs. For clarification, hydraulic assist is NOT something your vehicle would have come from the factory with, rather it is an upgrade that adds a hydraulic ram to the steering linkage to aid in steering. Most vehicles do NOT have this option, thus if you are unsure if you have it, you probably do not.
