A key advantage of buying remanufactured products is that our skilled machinists and technicians work with the latest-generation parts and the most recent manufacturer OE specifications. This allows us to fix any potential trouble spots or flaws that might have been in the initial design of the product.

Remanufactured products you purchase from Gearhead Engines are NOT used products or rebuilt. We remanufacture our product lines, allowing our skilled machinists to bring each product up to current OE standards OR BETTER. Remanufactured is NOT the same as rebuilt.

There are several advantages of remanufacturing over rebuilding.

• Our remanufactured products are machined using the latest manufacturer OE specifications. This results in higher quality than what might be expected with a rebuilt unit.
• Every Gearhead Engines product is fully SIM-tested, which is something a local shop may not have the ability to do.
• Additionally, our products are backed with fully-transferable, nationwide parts-and-labor warranties. This is something that likely won’t be offered if a local shop rebuilds the product.
• Lastly, we have a massive inventory of in stock transmissions, reducing down time, and getting you back on the road quicker!

Gearhead Engines offers a wide range of rear axle assemblies for both drum brake and disc brake equipped vehicles.

We sell OEM axles, so they will be the same weight.

Many trucks are equipped with open rear differentials, so upgrading to a limited slip (posi) unit will enhance off-road capabilities.

We are happy to provide you with any product we remanufacture. If you request a setup that is outside of the manufacturer’s configuration, we cannot guarantee fit or function.

Some engines are offered in multiple build levels, so be sure to ask your Gearhead Engines sales representative if you have any questions.

Hybrid battery cells lose capacity over time. When some cells degrade faster than others, the battery becomes out-of-balance. This is often what causes the vehicle warning light indicating battery failure.

Gearhead Engines offers hybrid batteries with Medium-Density cells, High-Density Cells, and 100% NEW cells.

• Medium-density cells qualify at 70-83% of their original capacity.
• High-density cells qualify at 83-100% of their original capacity.

Accordingly, vehicle owners will see a reduction in the longevity of the battery – this will affect the total range and gas mileage.

Our reconditioned batteries represent a much more affordable repair to the vehicle and, depending on your driving patterns, may not matter to you at all.

Many of Gearhead Engines’ product lines are remanufactured, meaning that they are taken apart and rebuilt to the same or better than OE standards.

In the case of our hybrid batteries and EV batteries, we recondition and grade the battery modules by capacity and group them for better performance.
