Overview
The Pro Comp PXA8142-29582 is a 20-inch by 9.5-inch aluminum split spoke wheel from the 42 Series Blockade line, with an 8 on 6.5 bolt pattern and a gloss black and milled finish. Pro Comp Alloy Wheels builds the Blockade with low-pressure casting technology.
Pro Comp rates its alloy wheels from 2500 to 3650 lb per wheel. The 42 Series Blockade pairs a light weight with a style offered in several finishes.
The wheel has an offset of -6, a backspacing of 5 and a 125 center bore. Pro Comp labels it universal fit, and the 42 Series Blockade is one of its alloy wheel lines.
Key features
- Low-pressure cast aluminum construction
- Split spoke style
- 20-inch diameter and 9.5-inch width
- 8 on 6.5 bolt pattern and 125 center bore
- Gloss black and milled finish
Choosing the right setup
Fit starts with the hub. The bolt pattern and center bore have to match the vehicle exactly, while offset and backspacing decide where the tire sits relative to the fender, control arms and brake calipers. Lower offsets push the tire outward, which can change steering feel and rub clearance on lifted or wide-tire builds, so measure before committing to a setup.
Split spoke designs leave gaps between the spokes where mud, brake dust and small stones collect. A quick rinse after off-road use keeps the milled faces clean and makes cracks, bent lips or dents easier to see. Choose a tire sized for this wheel’s diameter and width, and check that the rim width suits the tire’s recommended range before mounting.
- Check hub-centric fit and use rings where the center bore is larger than the hub
- Confirm brake caliper clearance with the new offset
- Match the lug nut seat style to the wheel
- Re-torque lug nuts after the first few drives

Vehicle fitment
This wheel is labeled universal fit and names no vehicle. Match the 8 on 6.5 bolt pattern, 125 center bore, -6 offset and 5 backspacing to your hub and to the clearance your vehicle has.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Offset changes where the tire sits in the wheel well, so check that the -6 offset and 5 backspacing clear your brakes and suspension before mounting tires. Confirm that the 125 center bore matches your hub’s pilot diameter, since a mismatch affects how the wheel centers.
