Part #: 2864S-MH-3T. Fits most 1988-1996 Chevy or GMC 1500 2X4 or 4X4 and 2500 2X4 Pickups. If you have a 1988-1991 you need to determine which side of the frame your steering gear mounts on. If it mounts on the inside of the frame then you have this steering gear. If it mounts on the outside of the frame then you need to order our Part number RH-2856.

If you are looking for the 2500 4X4 or the 3500 Pickups, then you need a RH-2864L-MH. The difference between these two is whether you have a small or large housing. To see which one you have, there are casting numbers on the housing. If you have an 83, then you have a small housing, the RH-2864S-MH. If you have an 84, then you have a large housing, the RH-2864L-MH. If you order a 2864L (84 Housing) and return a 2864S (83 Housing), you will only be refunded partial core credit.

Ratio 15:1 / 3 Turns
Input Small input w/25 Spline & Flat
Output 4 Master Spline w/ 32 spline
Fittings O-Ring

Accepting Upfront Refundable Core Charge:
This product does require a core charge deposit, that will be refunded upon return of your original core part.

Once the core has been received back and inspected, the core charge will be refunded back to the card or payment method originally used to purchase, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

Send My Core Box In First:
Not our favorite option, as this does add additional time to your order as your item will NOT be shipped until your old core box is received back and inspected FIRST.

Emailed core return instructions will be sent the following business day from order.

Once the core gear box has been received and inspected, the new gear box can be processed and shipped accordingly to the shipping method selected at checkout.

Pre-Paid Return Label:
You have the option for us to include a pre-paid return label for ease of returning/sending your core. With this option, you will merely need to drop the re-packaged core with accompanying shipping label off at a UPS drop-off. Otherwise, it will be your responsibility to supply your own means of returning the core. Pre-paid return label option is only applicable to the lower 48 contiguous United States. Please contact us if you have any questions.

Hydraulic Assist Ports Option:

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, your gear box will come with two more additional 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 oversized tires for offroad use. Most vehicles do NOT have or need this option, thus if you are unsure if you have it, you probably do not.
