The PowerStop Evolution AR82154XL is a rear left drilled and slotted brake rotor built on a 355 mm vented G3000 iron casting. Cross-drilled holes pull heat out of the friction surface while rounded slots sweep gas, dust, and water off the pad contact patch, so bite stays consistent when the truck is loaded or towing. Chamfered drill holes and rounded slot ends spread thermal stress to resist cracking. A silver zinc dichromate plating protects the hat and vanes from corrosion, and every rotor is 100% dynamic mill balanced to the original weight and vane count, so it bolts on with no modification.
