The RDRP B74 Aluminum Center Differential Case was developed to keep the drivetrain as consistent as possible throughout a long main event. The case is machined from aircraft-grade 7075-T6 aluminum and its design helps with heat dissipation in demanding racing conditions. Using the case not only improves the precision of the drivetrain, the greatly improved heat transfer also keeps the diff oil much cooler compared to using the standard plastic case. This results in a more consistent drivetrain behavior over the full run; even in high ambient temperatures. The diff case comes hard anodized for wear and looks and it includes a set of suitable hard-anodized aluminum inner cross pins for the internal gears.
- Made of aircraft-grade 7075-T6 aluminium for exceptional strength
- Hard-anodized finish for improved wear resistance
- Includes hard-anodized aluminium cross pins for a low overall weight and thus quicker spool-up and acceleration
