Introducing the ATC BK391 Bearing Kit, specifically designed for the Integras with a 5-speed transmission and differential from the model years 1996 to 2000 (GSR). This premium bearing kit is an essential upgrade for those seeking improved performance and durability from their vehicles.
The ATC BK391 includes a comprehensive set of high-quality bearings, meticulously engineered to enhance the overall driving experience. Each bearing in this kit is precision manufactured to exacting standards using superior materials. These bearings are designed to minimize friction, reduce noise, and increase load capacity, resulting in smoother operation and extended component life.
The kit includes the following bearings:1. Pinion bearing: The pinion bearing is an essential component that supports the connection between the pinion shaft and the differential. This bearing in the ATC kit is designed with high-strength steel and a hardened race surface for exceptional durability and performance.
2. Differential side bearings: The differential side bearings support the differential housing and help to maintain proper alignment. The bearings in this kit feature a double-lip seal design to prevent oil leaks and contamination.
3. Differential center bearing: The center bearing keeps the pinion shaft centered within the differential housing, ensuring optimal gear meshing and minimizing wear. The center bearing in the ATC kit is engineered with a high-grade steel material and features a precision-machined race surface for superior strength and durability.
4. Differential pinion seal: The pinion seal prevents oil from leaking out of the differential and ensures that the interior components are properly lubricated. The ATC BK391 kit includes a high-quality, flexible, and durable pinion seal designed to withstand the rigors of high-performance driving.
5. Differential pinion nut: The pinion nut holds the pinion shaft in place and secures the pinion bearing. The nut in this kit is precision-engineered for a secure fit and easy installation.
Installing the ATC BK391 Bearing Kit is a straightforward process, making it an ideal upgrade for both professional mechanics and DIY enthusiasts. By replacing the stock bearings with these high-performance alternatives, you can expect to notice improvements in the performance and longevity of your Integras 5-speed differential.
