GN C/T Hub Package Steel Hub & Rotor

The GN C/T Hub Package Steel Hub & Rotor from MOSER ENGINEERING is a precision-engineered hub assembly designed for builders and enthusiasts tackling serious high-performance or street/strip applications on Buick Grand National and Chevrolet Monte Carlo platforms. This complete hub package eliminates the need to source individual components separately, saving time during suspension or brake system overhauls. Whether you're building a restomod, upgrading braking geometry, or preparing a vehicle for road course duty, a quality hub assembly forms the foundation of safe, reliable wheel mounting and brake performance.

This package combines a steel hub with a matched rotor, ensuring concentricity and thermal stability critical for fade-free braking under sustained use. MOSER ENGINEERING's reputation in high-performance axle and drivetrain components carries over to their hub assemblies—each piece is manufactured to tight tolerances to minimize runout and vibration. The steel construction provides superior heat dissipation compared to cast alternatives, particularly valuable if you're pairing this with upgraded brake calipers or high-friction pads. At 33.05 lbs and measuring 12.3 x 12.2 x 12.6 inches, the assembly integrates seamlessly into OEM or custom suspension setups without requiring exotic brackets or adapters.

Mechanics and DIY builders restoring or modifying 1987–1991 Buick GN, GNX, or Chevrolet Monte Carlo SS platforms will find this right-hand hub package compatible with standard spindle configurations on those vehicles. Installation pairs well with performance brake upgrades, lowering springs, or coilover conversions where precise hub geometry maintains wheel alignment and prevents brake binding. The MPN 4200P54C-RH designation confirms this is the right-side assembly; verify your vehicle's year and original brake type (disc/drum configuration) before ordering to ensure proper fitment with your existing or upgraded caliper and rotor size.
