Sonnax SBK-G10 Koyo Thrust Bearing Kit For TH400 & 4L80E Transmissions '65 & Up

Transmission builders and rebuilders, this Sonnax SBK-G10 Koyo thrust bearing kit is exactly what you need for your TH400 or 4L80E transmission projects!

This comprehensive kit includes everything required for proper thrust bearing replacement: sun/internal gear bearings, center support/sun gear races, and center support/sun gear bearings.

These components are crucial for maintaining proper clearances and preventing axial play in your transmission - issues that can lead to premature wear, gear damage, and complete transmission failure if left unaddressed.

The Koyo bearings are known for their quality and durability, and when combined with Sonnax's engineering expertise, you're getting components that meet or exceed original equipment standards.

Whether you're rebuilding a classic TH400 from the '60s or working on a modern 4L80E, this kit ensures you have the right bearings for the job.

Proper thrust bearing installation is one of those details that separates amateur rebuilds from professional-quality work, and having a complete kit from a trusted brand like Sonnax takes the guesswork out of sourcing individual components.

If you're serious about transmission work, having quality bearing kits like this on hand is essential for builds that last and perform reliably under demanding conditions.

This is professional-grade stuff that makes a noticeable difference in how smoothly your transmission operates!
