GKTech Nissan S13 240sx Solid rear subframe conversion bushings

The GKTech Solid Rear Subframe Conversion Bushings for the Nissan S13 240SX are designed to allow you to install an S14 or S15 rear subframe into your S13 chassis. This upgrade offers access to improved suspension geometry, stronger component designs, and broader aftermarket support found in the later S-chassis models.

These bushings not only convert the mounting points to fit the newer subframe but also eliminate subframe movement entirely thanks to their solid billet aluminum construction, delivering sharper handling, better alignment control, and a more connected driving experience—perfect for drift and track builds.

Key Features:

• S13 to S14/S15 Subframe Conversion – Allows direct fitment of S14/S15 rear subframes into an S13 chassis.

• Solid Mount Design – Eliminates all subframe flex for precise handling and suspension response.

• Billet Aluminum Construction – Lightweight, corrosion-resistant, and incredibly durable.

• Improves Chassis Rigidity – Ideal for high-power or high-grip builds where compliance must be minimized.

• Direct Bolt-On Fitment – No welding or fabrication required.

Specifications:

• Material: 6061-T6 Billet Aluminum

• Fitment Type: Converts S13 chassis to accept S14/S15 subframes

• Design: Solid, non-compliant bushing for maximum rigidity

Compatibility:

• Chassis: Nissan S13 240SX (1989–1994)

• Subframe: Nissan S14 / S15 rear subframes
