 ISR Performance LS Swap Mounts for Nissan 240sx S13/14

The ISR Performance LS swap mounts are designed to be your one stop solution for all RWD LSx based motors and F-Body T56 transmission to fit in both S13 and S14 chassis.

By utilizing a small base mount pedestal and separate mount bracket the ISR Performance mounts can pivot to accommodate for the slightly different width and pitch between the two different chassis subframes. Where other manufacturers require you to purchase either S13 or S14 mounts, or do not fit ideally in each chassis, the ISR Performance mounts will work flawlessly in both chassis, allowing you to transfer parts from one chassis to another if needed!

ISR Performance mounts feature a urethane engine and transmission mount bushing to help dampen engine vibration without being overly stiff, the perfect solution for daily driven or track vehicles! 

*Lower mount holes on chassis side bracket is for S13, higher mount hole is for S14.*

  • 1x left motor mount

ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.


STEEL (steel bolts):  Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steels as well.
