DBA DBA52834.1 Series HD Two-Piece Brake Disc Ring - 5000

The DBA DBA52834.1 5000 Series HD Brake Disc Ring is a high-performance replacement cast iron rotor ring designed for use with DBA 5000 Series two-piece brake rotor assemblies. The HD variant features a smooth, OE-style rotor finish — the ideal choice for drivers who want the full performance benefits of the 5000 Series platform without slotted, cross-drilled, or dimpled surface treatments.

As a replacement ring, the DBA52834.1 allows existing 5000 Series owners to replace only the worn cast iron ring while retaining their aluminium hat, making it a cost-effective solution for high-use applications. First-time installers can pair this ring with a DBA 5000 Series aluminium hat to build a complete two-piece assembly.

Key Features:

• High Carbon Cast Iron Construction — Engineered for optimal interaction with DBA's thermal stability profiling, increasing the rotor's capacity to handle constant and extreme heat over prolonged periods
• Composite Two-Piece Design — Cast iron ring paired with an aerospace-grade T6061-T6 aluminium hat, reducing unsprung weight for improved vehicle dynamics
• NAS Hardware Compatibility — Designed to be assembled with National Aerospace Standards (NAS) bolts and crimp nuts; recommended torque of 13 Nm (9.6 ft-lb)
• Uniform Radial Disc Expansion — Aluminium hat design allows the cast iron ring to expand uniformly under heat, reducing warping and disc thickness variation
• Reduced Heat Transfer — Aluminium hat minimises heat transfer from the disc to the wheel hub, protecting bearings and hub components
• Kangaroo Paw Vane Design — DBA's patented internal vane geometry delivers up to 20% better heat dissipation compared to conventional vane designs
• Smooth HD Finish — OE-style surface finish with no slots, drilling, or dimples; compatible with a wide range of street and performance brake pads
• Sold Individually — Order two for a complete front or rear axle set

The DBA 5000 Series is recommended for high-performance street vehicles, track day and club racing, rally applications, and show vehicles. Pair with DBA performance brake pads for maximum system compatibility and braking performance.
