GKTech Nissan 240sx Polyurethane motor mounts (Pair)

The GKTech Polyurethane Motor Mounts for the Nissan 240SX (S13/S14/S15) are a performance-focused upgrade over soft, aging factory rubber mounts. Designed to minimize engine movement without the harshness of solid mounts, these are ideal for street-driven cars, drift builds, and track applications where durability and engine response matter.

Constructed with high-durometer polyurethane, these mounts maintain proper drivetrain alignment under load, improving throttle response, shifting feel, and chassis feedback, while still absorbing enough vibration for a comfortable driving experience.

Key Features:

• Reduces Engine Movement – Maintains engine and transmission alignment under high load.

• High-Durometer Polyurethane – Offers increased stiffness over rubber without the harshness of solid mounts.

• Direct OEM Replacement – Bolts in using factory hardware with no modifications needed.

• Durable & Long-Lasting – Resistant to oil, heat, and wear—ideal for high-performance use.

• Balanced for Street & Track – Great for daily driving, spirited canyon runs, and drift events.

Specifications:

• Material: High-durometer polyurethane with steel inserts

• Mounting: Direct fit for OEM engine brackets

• Fitment Type: Bolt-on replacement

Compatibility:

• Nissan 240SX S13 – 1989–1994

• Nissan 240SX S14 – 1995–1998

• Nissan Silvia S15 – 1999–2002
  Compatible with KA24DE, SR20DET, and most standard RWD engine swaps using factory-style brackets

What’s Included:

• (2) Polyurethane motor mounts (left and right)

• (1) Set of washers/spacers (if required)

Notes:

• May increase NVH slightly compared to factory mounts, especially with solid transmission mounts.

• Recommended to pair with a polyurethane or solid transmission mount for consistent drivetrain support.

• Professional installation recommended for engine alignment and torque specs.

Give your 240SX the support it needs with GKTech Polyurethane Motor Mounts—perfect for balanced performance, improved feedback, and long-term reliability on the street or track.

The GKTECH 240sx Polyurethane motor mounts are a direct replacement of the standard item and helps reduce motor movement and get power to the ground.

Particularly useful in a drift car where the car is off and on the throttle although all forms of motorsport will see an improvement in feel of the car but without the drastic increase in vibrations that the solid mounts see.

Our multi piece construction makes these differing to most Polyurethane motor mounts in that these don't just run a bolt all the way through a block of Polyurethane rather the 2 sides are separate and join by the Polyurethane.
