“Designed for use in conjunction with Holley/Hooker’s 240SX LS Engine swap kit for the S13/S14 Nissan 240SX”
What sets Ultra Mounts urethane mounts apart from our competition is our engine mounts have a two-part interlocking steel framework encased in urethane to give engine support in both directions of twist. When the engine tries to twist under acceleration the drivers side of the engine tries to lift, putting that mount in tension (pull apart) and the passenger side mount in compression (push together).
Then when you gear down into a corner or to stop, these forces are reversed. Ultra Mounts are correctly designed and take both of these forces into account.
