Overview
This replacement trailer wheel stud is commonly used on Dexter 5-lug trailer hubs for 3,500 lb axles. It features 1/2"-20 threads, a 2" overall length, 1.25" thread length, and a .61" knurl diameter for compatible press-fit hub and drum applications.
R&P Service Insight
Wheel studs should be matched by measurement, not just by axle rating. A stud that is too long, too short, or the wrong knurl diameter can create installation and lug-nut seating problems.
- Check the Knurl: The knurl must match the hub or drum bore for proper press-fit retention.
- Check the Length: This listing is for the 2" version, not the 2.25" 007-150-00 version.
- Check the Application: Confirm hub, drum, axle capacity, and existing stud measurements before ordering.
R&P Knowledge Hub
Compatibility: Commonly used on Dexter 5-lug trailer hubs for 3,500 lb axles and many 2004 and older 6,000 lb and 7,000 lb brake drums where measurements match.
Vehicle / System Fit: Trailer hub and brake drum wheel stud replacement for compatible press-fit applications.
Installation Notes: Press the stud into the hub or drum squarely. Do not rely on the lug nut alone to force an improperly matched stud into place.
Performance Insight: Correct knurl diameter and stud length help maintain proper wheel clamping and lug-nut engagement on compatible trailer hub assemblies.
Brand & Fitment Note
Selling Brand: R&P Carriages replacement trailer wheel stud.
Application Reference: Dexter references describe common compatibility only. Always verify against the existing stud and hub or drum measurements.
What This Means: This listing is for one replacement wheel stud for compatible trailer hub and brake drum applications.
Before Ordering: Verify thread size, overall length, thread length, knurl diameter, hub or drum style, axle rating, and quantity needed before installation.
R&P Repair Insight
Replace wheel studs when threads are damaged, stretched, cross-threaded, or when the stud no longer seats properly in the hub or drum. If multiple studs are damaged, inspect the wheel, lug nuts, hub face, and drum condition before returning the trailer to service.
- Thread Check: Confirm 1/2"-20 lug nuts are being used with this stud.
- Seating Check: Make sure the stud head seats flat after installation.
- Torque Check: Re-torque wheel hardware to the trailer or axle manufacturer’s specification after installation.
