Gain the upper hand on the trails, add more power, want an engine swap, need a turbo/supercharger installed, let us help you unleash unmatched torque and power off-road.

What We Do

Intake & exhaust

The easiest way to squeeze a little extra power from your engine is by replacing the factory intake and exhaust system. Less restrictive air intake and exhaust system mean the engine doesn’t have to work as hard to get air in or exhaust out and the result is an increase in power

turbo or supercharger

When it comes to achieving a substantial power boost, a forced induction system proves to be an excellent choice for specific applications. Whether you opt for a supercharger or a turbocharger, both options offer significant gains in power, each with their own distinct advantages. However, it’s important to note that not all options may be available for every vehicle.

By introducing forced air into the engine, whether through a supercharger or turbocharger, you can effectively increase the amount of fuel that can be added, resulting in a substantial increase in power output. Explore the possibilities and unleash the full potential of your vehicle with our selection of high-quality forced induction systems.

Engine swap

If you’re seeking the ultimate power improvement, upgrading the engine itself is the optimal choice. Many Jeeps come equipped with either a 4- or 6-cylinder engine, but converting to an 8-cylinder or a stroker 6-cylinder (on specific models) can yield a significant power gain. Keep in mind that depending on your vehicle, an upgrade to the transmission may also be necessary to accommodate the added power.

It’s important to note that when adding substantial power to your vehicle, there are various additional aspects to consider. Compatibility and integration are key factors, and our team is here to assist you throughout the process. With our guidance, you can ensure that all the components work harmoniously together, resulting in a satisfying and efficient power enhancement for your Jeep.

Changing the transfer case to a twin stick setup can provide ultimate control and enhance technical rock crawling abilities. By allowing independent control of the front and rear driveshafts, a twin stick transfer case enables more precise maneuvering and better traction in challenging off-road situations.

Twin stick transfercase

One of the most popular and reputable options for a twin stick transfer case replacement is the Atlas transfer case. Manufactured by Advance Adapters, the Atlas transfer case is known for its durability, strength, and versatile shift options.

However, it’s important to note that the availability and compatibility of twin stick transfer case options may vary depending on your specific vehicle make, model, and drivetrain setup. There are other manufacturers and options available for different vehicles as well.

Additionally, for vehicles with slip yoke style output shafts, a slip yoke elimination (SYE) setup can be beneficial. A SYE kit replaces the factory slip yoke on the transfer case with a fixed yoke and a shorter driveshaft. This helps improve driveline angles and reduce vibrations that are commonly experienced with lifted vehicles.

When making modifications such as axle swaps, transfer case changes, or adding lifts to your vehicle, it’s highly likely that a new driveshaft will be required. Upgrading to an aftermarket driveshaft offers several advantages, including increased operating angle capability and improved clearance, particularly in lifted applications.

JeReel Driveshafts

Aftermarket driveshafts are designed to handle higher angles without experiencing binding or vibrations, allowing for smoother and more reliable performance. They are often made with high-quality materials, such as stronger tubing and precision-balanced components, ensuring durability and better performance off-road.

While JE Reel is a well-known and reputable manufacturer of aftermarket driveshafts, it’s great to know that you have additional options available if needed. It’s important to consider factors such as your vehicle’s specifications, intended use, and personal preference when selecting the right driveshaft for your setup.
