Chassis and Platform Compatibility
Check vehicle configuration details before ordering portal conversion components. The W463A TIBUS portal axle system supports modern second-generation chassis:
- W463A / W464 (2018+): direct fitment for 4×4² and 6×6 custom builds across G63, G500, and G550 platforms.
- W463 Classic (2002–2017): incompatible due to different steering geometry, axle housing mounts, and control arm pickup points.
We strongly recommend professional installation and alignment calibration at a specialized workshop. Contact us on our Contact Us page for technical guidance.
