Overview
The Pro Comp 21124 is a 24-piece chrome lug nut kit with 12×1.25 spline lug nuts. The package includes four chrome valve stems and a lug socket.
Lug nuts are wheel hardware. The 12×1.25 thread should match the wheel’s studs before the nuts are used.
Key features
- 24 chrome lug nuts
- 12×1.25 thread size
- Spline style
- Four chrome valve stems
- One lug socket
Choosing lug nuts for your wheels
Lug nuts hold each wheel against the hub, so they carry the full load of the wheel and tire at speed and over rough terrain. Spline nuts seat on a matching tapered surface in the wheel, which keeps the clamping force even when the wheel has been removed and refitted several times. Before fitting a set, check that the wheel’s seat type matches the nut shape, because a mismatch can loosen under load even when the thread looks right.
Trail use puts extra stress on hardware. After the first few drives on rough ground, re-check torque with a calibrated wrench and look for cracked or deformed nuts. Chrome plating can chip where a socket has slipped, and bare metal exposed by chipping may corrode in wet or salty conditions. Keep a spare nut and the lug socket in the vehicle so a single damaged nut can be replaced on the trail.
- Check seat type against the wheel
- Re-torque after the first trail runs
- Inspect for chips and thread wear
