Are You Suffering from poor performance and reduced fuel economy resulting from oversized tires?

A Xtreme gear change will help get that performance and economy back!

If you've fitted larger tires to your vehicle then you are likely experiencing a loss in performance, fuel economy, and more constant transmission gear “hunting" - This is because the larger tires reduce your engine's RPMs below the optimal power band. Re-gearing the differentials in your vehicle is the only way to get your vehicle back into its optimal operating RPM range, thus improving performance and reducing strain on your vehicle's drivetrain. This is especially important for today's vehicles as they feature tall factory gearing and overdrive transmissions which are less tolerant to increase in tire size or the weight of added accessories.

It's a common misconception that gear changes are reserved only to hardcore off-roaders or trucks with huge tires. However, re-gearing is one of the single most beneficial modifications you can make to keep the performance, economy, and durability of your daily-driven 4x4. This is a mod for anyone with larger tires, increased weight, or for increased performance on stock vehicles for towing or increased acceleration.

The Ratios We Choose For Our Cruisers (everyone has their own choices, but we prefer for ourselves):

4.10  31"-32" Tire Diameter

4.30  33"-34" Tire Diameter

4.56  35"-37" Tire Diameter

4.88  38"-39" Tire Diameter

5.29  40"-44" Tire Diameter

Your new eLocker locking differentials:

The Eaton ELocker is an electronic, selectable differential designed for drivers that need traction on-demand. At the flip of a dash switch, drivers can go from open to 100-percent locked. A second flip of the switch deactivates the unit to resume normal driving. The ELocker is the most reliable on-demand differential, featuring selectable operation and net-forged gears for added strength.
