What is the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation system uses a unique pattern of 144 diamond and teardrop pillars inside the rotor. This design increases the surface area and improves cooling efficiency by up to 20% compared to traditional straight vane rotors, helping to dissipate heat more effectively.

What material is this rotor made from?

This rotor is cast from XG-150 high-carbon alloyed iron. This specific metallurgy is chosen to withstand the increased stress and heat generated during demanding braking applications.

Does this rotor come with hardware?

This product listing is for the rear brake rotor only. Installation hardware, such as lug nuts or brake pad hardware kits, is typically sold separately.

About this part

Product Details

If you're working on the rear brakes of your 2011, 2015-2016, or 2018 Jeep Grand Cherokee, or a 2018 or 2020 Dodge Durango with vented rear discs, this DBA 4000 Series rear brake rotor is a solid option. It's cast from high-carbon XG-150 iron, which helps it handle the extra stress and heat that comes with harder braking.

What really sets these rotors apart is DBA's Kangaroo Paw ventilation system. Instead of straight vanes, it uses a pattern of diamond and teardrop pillars. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard straight vane rotors. This means better heat dissipation, which helps prevent brake fade during extended braking periods. The 4000 Series HD variant offers a smooth, OE-style finish, making it a popular choice when you want the performance benefits without a visually altered look.
