The CUSCO 996338048639 is a high-performance rear differential unit designed specifically for Subaru Impreza WRX STI (GRB, GVB, VAB), Forester SJ5, and SJG models. This differential is an essential upgrade for those seeking improved power transmission and robustness for their Subaru vehicles, particularly for those who engage in rigorous off-road racing or track driving.
The CUSCO 996338048639 is a fully redesigned product manufactured using premium materials and advanced technology. Its primary construction is made of high-strength, low-alloy steel that ensures durability and resistance to fatigue. Moreover, it utilizes high-quality bronze gears and output shafts, which offer better wear resistance and longevity.
One of the most notable features of this CUSCO differential is its semi-domed, boxed housing design, which enhances its torsional rigidity. This increased rigidity ensures that power is transmitted more efficiently from the engine to the wheels, resulting in improved acceleration, enhanced traction, and smoother power delivery.
Another essential feature is the pinion gear's choice of materials and modification. The pinion gear is constructed of high-strength, SAE 4340 chrome molybdenum steel. To further enhance its capabilities, the tooth surfaces undergo a special shot peening process that increases its hardness and ensures a longer lifespan.
Additionally, this CUSCO differential includes a set of helical LSD (Limited Slip Differential) gears. These gears provide equal power distribution to both the inside and outside wheels during cornering, preventing excessive tire slip and ensuring maximum grip. As a result, the vehicle maintains better traction and exhibits improved handling.
The CUSCO 996338048639 also includes precision-engineered oil cooling channels and baffles. These features ensure an optimal operating temperature for the differential, reducing the likelihood of overheating even under extreme conditions. When combined with the high-quality oil and filter recommended by CUSCO, this cooler system ensures efficient lubrication and enhanced longevity.
This rear differential unit ships with all necessary hardware, bushes, and gaskets. The installation process is straightforward and can be accomplished in a day with standard hand tools. Additionally, it comes with comprehensive instructions to guide users through the process.
In conclusion, the CUSCO 996338048639 is a top-tier differential upgrade for Subaru owners who wish to enhance their vehicle's power transmission and durability. Its robust steel construction, improved torsional rigidity, high-performance gears, and circuit cooling system make it an ideal choice for off-road racing, track driving, and everyday use.
