If your steering needs an upgrade from running oversized tires, offroading, or your stock gearbox is just simply worn out and you demand nothing but the best, then a Red-Head gearbox should be your next move. While the standard Red-Heads we offer outperform the stock box in every way, their Extreme Duty models are built to handle anything you can throw at them while still being completely suitable for a daily driver with stock-sized tires.

*IMPORTANT SEE APPLICATION NOTES BELOW.
Featuring many of the same upgrades as the standard Red-Head box for improved steering, the Extreme Duty models feature a larger internal piston, as well as a larger sector shaft compared to the standard models. The larger piston means that more fluid can be displaced, providing easier "push and pull" of your steering linkage. As far as the shaft, bigger is nearly always better in terms of strength, so you're less likely to twist or break the shaft even under the harshest of conditions. The sector shaft will taper down to the stock size, however, so you're able to retain your existing pitman arm. This is a major advantage, especially for those with lifted trucks with dropped pitman arms, as you will not have to change your pitman arm.

IMPORTANT NOTES:

• If you have a 2008 model year, please check the vehicle build date located on the driver's side front door. If the vehicle is built 07/07 or prior, you will need a different gearbox, Red-Head part number 2768 (See Related Products section) that is designated as fitment of 2005-2007 model years.
  
• If you have a 2010 model year, please check the vehicle build date located on the driver's side front door. If the vehicle is built 03/10 or later, you will need a different gearbox, Red-Head part number 2773 (See Related Products section) that is designated as fitment for the 2011-2016 model years.
  
• You have the option for us to include a pre-paid return label with the shipment for ease of returning your core.
