Wilwood Racing announces the release of the newest evolution of its legendary Wide 5 hub series for
rear axles, a Starlite 55XD featuring 1-Ton Bearing Races. Building on more than 40 years of proven
performance, the Starlite 55XD continues the legacy established by the groundbreaking Starlite II “bubble”
hub—an industry-transforming design that introduced lightweight strength through advanced engineering
pioneered by Wilwood.
The Starlite 55XD model, with 1-ton bearing races for rear axles adds stiffness and durability. Includes
coarse studs and a forged aluminum adapter plate compatible with 8 x 7.00-inch fixed or floating rotors,
and Wilwood’s Lug-Drive dynamic mount system. This expanded mounting versatility gives race teams
greater flexibility in building high-performance, track-ready braking systems.
Recognized for decades as the foundation of competitive short track braking setups, Wilwood’s Wide 5
hubs remain a trusted standard across the industry. The introduction of the latest Starlite 55XD with 1-ton
bearing races further reinforces Wilwood’s commitment to performance-driven engineering.
