What is a 2-piece rotor and can I just buy the ring?

A 2-piece rotor has a separate iron friction ring and an aluminum or steel hat. This allows for weight savings and better heat management. Yes, this product is just the replacement iron rotor ring, designed to be bolted to an existing DBA 5000 Series aluminum hat.

What is the benefit of the aluminum hat?

The aerospace-grade aluminum hat significantly reduces unsprung weight compared to a traditional one-piece rotor. It also helps to better manage heat transfer from the rotor to the wheel hub and allows the iron friction ring to expand uniformly.

Is this rotor drilled or slotted?

This is the 5000 Series HD variant, which features a smooth OE-style rotor finish. It is not drilled or slotted, making it a popular choice for drivers who want the performance benefits of the 5000 Series but prefer a plain rotor surface.

About this part

Product Details

DBA is known for making solid brake components, and their 5000 Series rotors are a prime example. This is a replacement rotor ring for your 2008-2011 Nissan Pathfinder with the 5.6L engine. It's designed to work with the two-piece rotor assembly, meaning you can reuse your existing DBA aluminum hat if it's still in good shape, just swapping out the worn-out iron ring. This setup is a direct replacement for your stock setup, but with some notable upgrades.

What sets the 5000 Series apart is its two-piece construction. It combines a high-carbon cast-iron friction ring with an aerospace-grade T6061-T6 aluminum hat. This isn't just for looks; the aluminum hat significantly cuts down on unsprung weight, which can make a difference in how your suspension handles. It also helps manage heat better by reducing how much heat transfers from the rotor to your wheel hub. This particular ring has a smooth OE-style finish, making it a great choice if you want the performance benefits of the 5000 Series without the drilled or slotted look.

This rotor ring is a solid option for high-performance street driving, track days, or club racing. It's built to handle demanding situations while offering improved heat management and reduced weight compared to a standard one-piece rotor.
