Info

On your '55-'57 Chevy car, the front motor mounts are at the front of the block and the rear mount attaches to the bellhousing. This works fine for original use, but makes it hard to swap in a different tranny or add belt driven accessories to the front of the engine. This mount kit is the solution!

The best of both worlds: Tri-Five Chevy mated with the mighty LS engine platform. Designed from scratch, this engine mount kit locates off of factory frame rivets to ensure proper alignment. It’s never been easier to upgrade the driveline of your Bel-Air or 210 with a modern power plant. This kit includes LS engine mounts as well as a transmission crossmember for the '55-'57 Chevy.

  • Bolt-in, no welding required
  • Drill 4 holes for the engine mounts, 2 are factory rivets to ensure proper bracket placement
  • Drill 4 holes for the transmission crossmember, this is done with crossmember attached to transmission to ensure proper placement
  • Kit comes with adapter plates and rubber mounts for LS engines
  • Crossmember mount works with "most" modern era GM transmissions that have a mount on the tailshaft
  • Crossmember is compatible with "two-bolt" style trans mounts such as 91018016 or 91025820
