3Racing Differential Spacer MKF-03A Drift and Race Shim  [MKF-03A]

Accurate Diff Spacing with 3Racing Differential Spacer MKF-03A

The 3Racing Differential Spacer MKF-03A is intended to fine-tune the spacing inside a model differential for steadier gear engagement. Compatible with the #MKF-03/BU, #MZII-003/V2, and #KZ-09 models, the spacer assists in keeping the diff stack at the correct clearance, which promotes smooth running and reduces premature wear under normal and spirited driving.

What the MKF-03A Adds to Your Setup

Produced with consistent tolerances, the spacer helps cut down on internal friction and uneven load on gears. That reliability can translate into more predictable handling and fewer drivetrain issues over time, making it a sensible part for routine servicing and tuning tweaks.
