Overview
The Pro Comp Series 75 Trilogy Race Beadlock in 17×9 inches is a satin black aluminum wheel, part number PXA5175-798347M, with a 6 on 5.5 bolt pattern and a 108 center bore. It is the -6 offset version of the 75 Series beadlock, offered by Pro Comp Alloy Wheels for trucks and SUVs that need a 17 inch alloy with a beadlock design.
The wheel has a -6 offset, which places the mounting face slightly behind the centerline, and a 4.75 backspacing that measures the distance from the mounting face to the back edge of the rim. The title gives the offset as -6mm, so that is the number to check against the vehicle’s clearance.
A beadlock wheel uses a locking ring to hold the tire bead against the rim, which differs from a standard alloy wheel. Confirm the locking-ring hardware your tire needs before ordering.

Beadlock setup basics
A beadlock wheel holds the tire bead to the rim with a locking ring, which keeps the tire from rolling off the wheel when it runs at low pressure. This setup is common on trail rigs that air down for rocky ground. The ring, its bolts and the bead seat all carry load, so they need to be matched to the tire you run.
Before installation, clean the bead seat and inspect the rim for dents or cracks that would stop the bead from sealing. After the first few trail runs, re-check the locking-ring hardware and the lug nuts, since they can loosen as the tire settles. Inspect the wheel after hard impacts and replace any part that shows damage.
- Confirm the locking ring matches your tire and rim
- Check ring bolts before each trip
- Inspect the bead seat for corrosion or damage

Vehicle fitment
This wheel is not tied to a named vehicle, year or chassis code. The hub must match the 6 on 5.5 pattern and the 108 center bore, and the -6 offset with the 4.75 backspacing should be compared with the fender and brake clearance on the vehicle. The universal fit label is a catalog term, not a fit guarantee.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Follow the locking-ring and bead seating steps that come with the tire and beadlock hardware. Confirm the rim clears the brake caliper with the suspension compressed.
