TrailerApp Spindles and Components
Precision-Built Axle Hardware for Heavy-Duty Applications
Overview
The TrailerApp Spindle and Component Series is designed for professionals who demand repeatable accuracy and long service life. Each spindle, flange, and alignment tool is machined to strict tolerances for consistent fitment and smooth bearing operation, whether you’re repairing a damaged axle or fabricating a new one from scratch.
Built from heavy-wall forged steel and engineered for high-load use, TrailerApp components are proven in applications ranging from equipment haulers and lowboys to livestock, flatbed, and industrial trailers. These parts restore proper geometry, protect tire wear, and ensure your hubs run cool and true even under severe duty.
All TrailerApp products integrate directly with standard Dexter, AL-KO, and Lippert style hub and bearing sets, giving builders and service shops reliable interchangeability and easy field service.
