Overview
The Pro Comp 51-6866 is a 16 x 8 in windowed steel wheel in gloss black, from the Rock Crawler Xtreme Series 51 line. It has a 5 on 4.5 in bolt pattern and an 83 center bore.
Rock Crawler Xtreme wheels are built from steel with a durable black powder coat. Wheel width and backspacing together determine how far the wheel sits in the wheel well, so both figures matter when matching a wheel to a hub.
Key features
- Windowed steel construction
- 16 in diameter and 8 in wide
- 5 on 4.5 in bolt pattern
- 83 center bore
- Gloss black finish over a durable powder coat
- Rock Crawler Xtreme Series 51 styling
Maintaining a windowed wheel
Windowed wheels have openings that trap mud and grit, so clean the inside after each muddy outing and check the brake area for buildup. A powder-coated finish resists everyday wear, but the lip, bead seat and spoke edges take the most impacts. Look at these areas for scrapes or bends before a trip and touch up exposed steel to slow rust.
Backspacing and width together set how far the wheel sits in the wheel well, so keep a record of your current figures when you swap wheels. Compare the new wheel’s bolt pattern and center bore with the hub, then test fit with the tire before mounting. Re-torque lug nuts after the first drive and again after tire changes.
- Clean debris from the window openings
- Touch up chips on the lip and bead seat
- Log backspacing and width before a swap
- Recheck lug torque after the first few miles
