TRAILER AXLE COMPONENT / WELD-ON REPLACEMENT SPINDLE
10,000 lb Dexter GD SHORT Trailer Axle Spindle - General Duty
A SHORT-style replacement spindle engineered specifically for Dexter 10,000 lb General Duty (GD) trailer axles to restore alignment and braking geometry.
Part Number: TAD10KGD ?? SHORT Configuration 5.00" Shoulder-to-End
Overview
The TAD10KGD is designed ONLY for Dexter 10,000 lb General Duty axles. It is a weld-on solution used to repair axles where the original spindle has been damaged or worn. This spindle maintains proper hub support and braking geometry when installed according to Dexter dimensional standards.
R&P Service Insight
Identification is everything. Dexter produced both "Long" and "Short" versions of the 10K GD spindle. They are not interchangeable.
- Critical Measurement: Measure from the bearing shoulder to the end of the threads. If it is 5.00", this is your spindle.
- Exclusivity: This will NOT fit Lippert, AL-KO, or other brands.
- Installation: Weld-on spindles require precise alignment to prevent premature tire wear and bearing failure.
R&P Knowledge Hub
Compatibility: Replacement for Dexter 10,000 lb General Duty (GD) Axles only.
Component Match: Designed for use with Inner Bearing 25580, Outer Bearing 387A, and Seal 10-51 (2.875" ID).
Primary Identification: 5.00-inch distance from the bearing shoulder to the end of the threads.
Safety Note: Because this involves structural welding on a load-bearing axle, professional installation by a qualified welder/mechanic is strongly recommended.
R&P Repair Insight
Replacing a spindle is a precision job. Ensure the axle tube is cut clean and squared before beginning the welding process.
- Removal: Cut the old spindle approximately 1" from the original weld.
- Alignment: Carefully align for correct camber and toe; tack weld and verify before final 360° weld.
- Reassembly: Always use new bearings, races, and seals when installing a new spindle.
