Why should you re-gear a lifted truck? When you buy a stock truck, the gears (gear ratio) are set to power the truck based on the stock products. When you put a suspension lift on your truck and add bigger tires, the gears of the truck are still set to power the stock tires. That means the gears have to work harder to make the tires move. If you are just upsizing to 35″ tires, you shouldn’t see a big difference in performance. But when you move from 31-33″ tires to 40″ or bigger tires, you will notice a major slowdown in your acceleration. Not only that, it means that your engine (and gears) are working harder to make your lifted truck move.

So what’s the solution? Think about having your big truck re-geared. By doing this, you are basically re-programming your truck as if it had big tires since it came off the assembly line. Okay, that’s a little bit of an exaggeration, but re-gearing will have a big impact on your acceleration and help preserve your engine.

One note is that if you have a big truck AND are towing, re-gearing will be critical to saving your engine. Many people lift their truck 15″ and add 40″ tires, but don’t think to re-gear or add engine mods. The problem is that your truck will be working harder to power the truck and even harder to tow. After a while, it will get tired and break down.

Check with your local shop or mechanic on getting your lifted truck re-geared. It is a small step that can save you a lot of time, money, and inconvenience.
