ISR Performance Adjustable Engine Mount Set - Nissan 240sx

The ISR Performance Adjustable Engine Mount Set for the Nissan 240SX is a complete drop-in solution for engine swap or factory mount replacement. Two polyurethane bushings plus eight solid spacers let you dial in motor height, and the design plays nicely with Hooker LS swap mount brackets for LS-into-240SX builds.

What It Does

Old factory rubber engine mounts crack, sag, and let the engine shift under load, fouling steering geometry and chewing up motor mount studs. The ISR adjustable set replaces both sides with polyurethane bushings and ships with eight solid spacers, so you can adjust motor height up or down depending on swap geometry, hood clearance, or oil pan clearance to the crossmember. Specifically called out as compatible with Hooker LS swap mount brackets, making it a foundation piece for LS-into-240SX builds. Pairs naturally with our IS-TMK-240 transmission mount for a complete drivetrain mount refresh.

Fitment

Designed for the Nissan 240SX as a general engine mount upgrade for factory engines or swap applications. Confirmed compatible with Hooker LS swap mount brackets for 240SX LS swaps.

What's in the Box

• 2x polyurethane engine mount bushings
