PowerStop Z36 vs R1 Concepts
If the truck tows, I start with Z36. R1 Geomet is the cheaper coated kit I would use on a pavement daily, not a hard-working tow rig.
We may earn a commission from retailer links. We focus on use case and fitment, but you should always confirm current price and compatibility before ordering.
My call
My call: Z36 for towing heat, payload, hills, and bigger tires. R1 Geomet only wins when the truck is mostly daily-driven and the exact front/rear kit is clear.
PowerStop built Z36 around the truck problem: weight, heat, and repeat stops. R1 Geomet is more of a coated value kit, which is fine on a street-driven truck, but I do not treat coating as a substitute for heat margin.

Cheaper coated kit for a daily truck
Heat
Towing exposes weak pads fast. I care more about fade margin than saving a little on a kit.
Hardware
Check whether the listing includes front, rear, or all four corners. Kit names do not tell you that.
Fitment
Rotor diameter, drivetrain, trim, axle position, and brake package matter before brand preference does.
