R&P Knowledge Hub
Straight spindles use the same inner and outer bearing size (L68149 / L68149). This differs from standard #84 trailer spindles, which use two different bearing sizes.
Always verify your existing bearing numbers before ordering. Marine applications require proper seal installation and corrosion-resistant components.
Important: Confirm spindle type (straight vs. step spindle) before installation.
