At DMG Motorsports, we present the APM Transmission Bearing Support, designed to support the transmission main/shaft when the inner primary is discarded for an open belt. Its sealed ball bearing supports the main/shaft and the weight of the clutch basket and associated parts.

Features:

• Supports the transmission main/shaft for open-belt applications
• Cast from 356 T6 high strength aluminum
• Automotive-style sealed ball bearing
• Fits 1965-up Big Twin 4-Speeds with rear chain only
• Will not work with a super nut
• Must use the stock main/shaft nut
