Trailer Hub Hardware / Wheel Stud & Lug Nut Kit Eight Drive-In Trailer Hub Studs w/ Nuts – 9/16-18 x 2-5/16 – Fits 5200–7000 lb Dexter Axles SKU: 71328-KIT Eight-piece drive-in trailer wheel stud and lug nut kit for compatible trailer hub applications. Built for buyers replacing damaged, worn, or missing hub studs where the thread size, length, spline, and press-fit dimensions match. 9/16"-18 Thread 2-5/16" Overall Length 8 Studs + 8 Nuts Overview This 71328-KIT includes eight drive-in trailer wheel studs and eight matching lug nuts for compatible trailer hub applications using 9/16"-18 wheel hardware. It is intended for measurement-matched hub repair where the existing stud length, spline / knurl diameter, and press-fit dimensions match the replacement hardware. R&P Service Insight Wheel studs are small parts, but the measurements matter. A stud can have the correct thread size and still be wrong if the knurl diameter, shoulder, or installed length does not match the hub.
- Press Fit: Drive-in studs should be installed squarely into a compatible hub bore.
- Measurement Check: Match thread size, overall length, spline / knurl diameter, and base dimensions before ordering.
- Hub Condition: If the hub stud hole is wallowed out, damaged, or loose, replacing the stud alone may not solve the issue.
R&P Knowledge Hub Compatibility: This kit is for compatible trailer hubs using 9/16"-18 drive-in wheel studs. Fitment is determined by measurements, not axle rating alone. Trailer / Hub Fit: Commonly used on compatible 5,200 lb, 6,000 lb, and 7,000 lb trailer axle hub applications where stud dimensions match. Installation Notes: Press the studs into the hub evenly. Do not rely on the lug nut alone to pull an incorrect or oversized stud into place. Performance Insight: Proper stud fit helps maintain wheel clamping force and prevents stud movement in the hub during service. Brand & Fitment Note Selling Brand: R&P Carriages curated trailer hub hardware kit. Application Reference: Dexter-style or OEM-style hub references are used only as application guidance where the buyer’s measurements match. What This Means: This listing is for a wheel stud and lug nut service kit, not a guaranteed OEM-branded hub-specific kit unless otherwise verified on the product packaging or listing record. Before Ordering: Verify thread size, overall length, spline / knurl diameter, shoulder, base diameter, hub condition, and included components before installation. R&P Repair Insight For trailer hub stud repair, the most common ordering mistake is matching only the thread size. Confirm the complete stud profile before replacing hardware.
- Check Thread: Confirm 9/16"-18 thread matches your existing lug nuts and wheel hardware.
- Check Spline: Confirm the spline / knurl diameter matches the hub bore so the stud seats tightly.
- Check Length: Confirm 2-5/16" overall length provides proper wheel and lug nut engagement for your hub and wheel combination.
