Product Details

The R1 Concepts 623-54190L is a drilled disc brake rotor from R1 Concepts' RNC Series, engineered to deliver reliable stopping performance as a direct OEM-fit replacement. Built to original equipment specifications, this rotor installs without modifications and is sold as a single left-side (driver's side) unit.

Key Features:

  • Precision Cross-Drilled Holes: Countersunk and chamfered drill pattern reduces heat buildup on the rotor surface, improving thermal dissipation and helping prevent rotor cracking under repeated braking cycles
  • G3000 Grade Cast Iron Construction: High-grade iron alloy provides the strength, stability, and thermal capacity needed for consistent, fade-resistant braking performance
  • Zinc Plated Coating: Protective zinc finish applied to the hub and vane structure guards against corrosion, extending rotor lifespan and maintaining appearance
  • Double Disc Ground Surface: Promotes faster, more even brake pad bed-in for quieter, smoother braking right from the start
  • OEM Direct Fit: Manufactured to original equipment specifications — no drilling, cutting, or modification required for installation
  • Single Rotor (Left/Driver Side): Part number 623-54190L is a single replacement rotor for the left side of the axle

R1 Concepts recommends replacing brake pads whenever new rotors are installed. A proper break-in (bed-in) procedure should be followed after installation to transfer an even layer of pad material onto the rotor surface and achieve optimal braking performance.

We found a tire here that was hard to find and it was shipped quickly. Great experience and would use this company again.

Ordered replacement seats for my fishing boat. I was shocked and impressed with the quality of the seats. They look as good as the originals from Tracker. Shipping was great, arrived sooner than I expected.

Great price, good quality, and excellent communication

I contacted customer service because I was not able to sign on with google to leave a positive review. they did not get back to me within 24 hrs like they say Also pictures show the incorrect product for the description for example a picture of Interlux 2333N has a description for Interlux 333, different product yes some pictures for the Interlux 333 show the correction description I assumed you don't have Interlux 2333N so I ordered from someone else.
