Maserati 204121

The MS-204121 spacer is an essential component for precision engineering in Maserati vehicles. Designed to maintain optimal alignment and reduce vibrational stress, this OEM-grade part ensures your Italian masterpiece performs as intended. Here's how to verify compatibility and install it correctly.

Engineering behind the spacer

The MS-204121 spacer serves as a crucial interface between suspension components, manufactured from aircraft-grade aluminum with a hard-anodized finish. The SKU: MS-204121 identifies this specific 8mm thickness variant designed for Maserati Quattroporte and Ghibli models. Proper installation requires torque specifications of 110 N·m ±5% and sequential tightening patterns to prevent warping.

Performance implications

This spacer directly impacts wheel bearing longevity and handling characteristics. When worn beyond the 0.1mm tolerance threshold, it causes uneven tire wear and steering wheel vibration at highway speeds. Our inventory at SparesUSA.net contains only Marchesini-manufactured spacers identical to Maserati factory specifications, pressure-tested to withstand 1,200 MPa loads.

Complementary components

Our spacer works with several performance upgrades: - Maserati OEM wheel hubs for perfect mating surfaces - Brembo brake kits requiring specific clearance - Novitec suspension lowering springs - Pirelli P Zero Nero tires - Technical support team for installation queries
