Most Late-model factory oil pans bolt to the engine block and the transmission for extra strength and support. Most swap oil pans for the Gen III Hemi do not have this additional support, but it can be added using PN # 302-65. This lower support fits cast, fabricated, and stamped swap pans on Gen III Hemi engines with popular transmissions (or bellhousings). The lower structure support also covers the bottom of the transmission (or bellhousing) to keep out dirt and reduce vibration & noise.

Features:

  • Lower support bolts engine block to transmission or bellhousing for additional driveline strength and support while keeping dirt and debris out of driveline components
  • Provides OEM style fitment and support on oil pans that do not bolt to the transmission
  • Fits engine swap oil pans: 302-60, 302-61, 302-64, 302-64BK, 5050WND, 5051WND, WB11010, and stamped steel factory oil pans
  • Fits all Gen III Hemi engines – 2003 & Up 5.7, 6.1, 6.2, and 6.4-Liter
  • Fits all common transmissions: TR-6060, NAG1, 545RFE, 8HP70, 8HP90, 9HP75, A727, 46RE, 46RH + More
  • Fits Lakewood bellhousings: LK7000 or LK7000K with Mopar 3-speed, 4-speed, or Tremec TKO/TKX transmissions
  • Covers the lower portion of the bell-housing – to keep dirt out of the bell-housing or transmission
