Overview
The Pro Comp 21134B is a 6-lug black spline kit with 12×1.5 thread size. It includes a valve stem, which the title and description both note.
Lug kits are wheel hardware, so the six-stud layout and 12×1.5 thread decide whether the kit suits a wheel.

Six-stud wheel basics
A six-stud pattern spreads wheel load across more contact points than a five-stud layout, and it is common on heavier-duty axles. Because the bolt circle must match exactly, measuring the existing wheel before buying a kit saves a return. Spline seats also need to match the wheel’s taper, so compare the seat style as well as the thread.
Thread pitch and stud length work together. A nut that seats fully on a short stud can still leave threads exposed or engage too little thread. Check that studs are not bent or stripped before installing new hardware, and clean the threads with a wire brush. Stripped threads are common after removing stuck nuts, and a damaged stud should be replaced before the wheel goes back on.
- Measure bolt circle before buying
- Check seat style matches the wheel
- Inspect studs for bends or stripped threads
