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.
