Experience a smoother, more reliable driving experience with Trekline Motorsport's Carrier Bearing Spacer and Rear Brake Line Bracket Kit, specifically designed for Tundra trucks with 3" or larger lift blocks. When lifting a truck, the driveshaft angle can change, causing driveline vibrations and premature wear on components. Our carrier bearing spacer helps restore proper driveshaft geometry, reducing vibrations and extending the life of components like universal joints and the carrier bearing itself. In addition, our kit comes with a Rear Brake Line Relocation Kit, complete with brackets and hardware, allowing you to use the factory rear brake lines. This comprehensive solution ensures optimal driveline performance while maintaining your truck's braking system. Invest in Trekline Motorsport's Carrier Bearing Spacer / Rear Brake Line Bracket Kit and enjoy the perfect balance of lifted aesthetics and reliable functionality.
