Product details
This anodized right front Wilwood TX6-DM is a component of the heavy-duty GM 2500/3500 conversion documented for 2020 and later trucks.

Fitment & Compatibility
Confirm the truck's exact application and the matching Wilwood conversion hardware. The direct-lug caliper still requires the specified rotor, flexline and wheel clearance; it should not be treated as a stock-rotor replacement merely because it bolts to the spindle.
With 20+ years of experience, PMB Performance can help assess the brake hardware. Provide the caliper number, rotor dimensions and bracket measurements when asking about compatibility.
