Review RACING POWER COMPANY 5/8

The Racing Power R5682C 36-spline X3:4DBL is a high-performance differential upgrade kit designed for serious off-road enthusiasts and competition racers. This differential kit is specifically engineered for vehicles with a 36-spline X3:4DBL rear end, such as certain Jeep Wrangler JK models.

At the heart of this kit is a high-strength, forged steel differential housing. This housing has been precision-machined to ensure a perfect fit and maximum durability. The housing also features an integrated carrier bearing mount, making installation easier and more efficient.

The Racing Power differential kit comes with a set of high-performance ring and pinion gears. These gears are made from heat-treated steel and are precision-machined for optimal strength and accuracy. The ring gear has a tooth count of 56, while the pinion gear has a tooth count of 82, providing an excellent gear ratio for off-road applications.

One of the key features of this differential kit is its 36-spline output shaft. This shaft is made from high-strength steel and is designed to handle the extreme loads and torque of off-road driving. The 36-spline design also allows for the use of stronger, larger U-joints, which improve durability and reduce the risk of failure.

Another important feature of this kit is its heavy-duty spider gears. These gears are made from high-strength steel and are precision-machined to ensure optimal tooth engagement and durability. They are also designed to handle the high torque loads of off-road driving, making them an essential upgrade for anyone looking to take their vehicle to the next level.

The Racing Power R5682C 36-spline X3:4DBL differential kit is also compatible with a variety of locking differentials, including the ARB Air Locking Differential and the Detroit Truetrac Differential. This makes it an ideal choice for those who want to add extra traction and control to their off-road vehicle.

In summary, the Racing Power R5682C 36-spline X3:4DBL differential kit is a high-performance upgrade designed for serious off-road enthusiasts and competition racers. It features a strong, forged steel housing, high-performance ring and pinion gears, a 36-spline output shaft, and heavy-duty spider gears, making it capable of handling the extreme loads and torque of off-road driving. Plus, its compatibility with various locking differentials makes it an excellent choice for those who want to add extra traction and control to their vehicle.

The Racingsport R5682C 36-spline IRS differential is an excellent upgrade for Subaru WRX and STI owners seeking improved performance, durability, and adjustability. However, it comes with a premium price tag, complex installation, potential noise, and vibration.
