DBA DBA42093 4000 Series HD Solid Rear Disc Brake Rotor

The DBA DBA42093 is a 4000 Series HD solid rear disc brake rotor engineered as a direct OE replacement with upgraded performance characteristics. Designed for Land Rover applications from 2002–2005, this single-piece solid rotor delivers reliable, consistent stopping power for daily driving and light off-road use.

Key Features:

• 4000 Series HD construction — smooth OE-style rotor face, ideal for applications requiring a factory-correct appearance
• High-carbon alloyed iron casting for superior strength, resistance to cracking, and extended service life
• Thermal Stability Profiling (TSP) — heat treatment cycles realign the iron's microstructure for increased rotor stability and durability under repeated heavy braking
• Solid rotor design — appropriate for rear axle fitment where solid (non-vented) rotors are specified by the OEM
• CBN (Cubic Boron Nitride) machine-turned finish — minimizes disc thickness variation, reducing the potential for pad knock and premature wear
• Centre-split core castings — improve heat transfer and thermal efficiency throughout the rotor body
• Non-directional / symmetrical design — suitable for universal left or right fitment
• Thermo-Graphic Heat Paint — paint markings change colour at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Painted non-friction areas to prevent rust and enhance appearance

The DBA 4000 Series HD rotor is the ideal upgrade for drivers who want the metallurgical and thermal advantages of the 4000 Series platform in a clean, OE-style finish. It is a direct bolt-on replacement that requires no modifications for installation.
