- This is a pair of XT5-6Lug aluminum hubs, a six-lug hub specially designed for Boom Racing 1.55" ProBuild wheels. This hub uses the XT5 center cap system, with a six-lug bolt pattern. The XT5-6Lug hub bolts are less spaced out than the XT6 six-lug hub bolts for a more realistic scale look.
Made of billet CNC aluminum.
This hub does not require wheel hex, it uses a pin to secure directly on the drive shaft.
Note: This is not the same as the six lug XT6 wheel hubs. XT5-6LUG is smaller than XT6 made for 1.55 six lug faceplates.
Note: The XT5 hubs do not fit M5 wheel nuts or 8mm nut wrenches.

- Diameter: 20mm
