GKTech Nissan 240sx/Skyline/300zx chassis Polyurethane Differential Bushings - front and rear bushes

The GKTech Polyurethane Differential Bushings are a direct replacement for the factory rubber units on the S-chassis, RWD Skyline, and Z32 300ZX platforms. This complete set includes both front and rear bushings, offering a balanced solution for reducing diff movement while keeping NVH (noise, vibration, harshness) to a minimum—ideal for performance street cars, track builds, or drift setups that need reliability without going full solid.

Made from high-quality polyurethane, these bushings reduce drivetrain slop and help eliminate wheel hop under hard acceleration. They're press-in replacements that maintain OEM fitment and are a smart upgrade for any aging or modified rear end.
