SuperPro 1989 Nissan 240SX Rear Crossmember Mount Insert Bushing Set

If you're looking to firm up the rear end of your 1989-1998 Nissan 240SX, these rear crossmember mount insert bushings from Superpro are a solid option. They replace the stock rubber bushings in the rear crossmember, which can become worn and soft over time, leading to sloppy handling and alignment issues. By installing these polyurethane inserts, you'll get a more direct connection between the chassis and the suspension components.

Superpro makes these bushings from a proprietary engineering-grade polyurethane formula that's designed to hold up better than rubber, especially in harsh conditions. This material is unaffected by extreme temperatures, oils, and moisture, so you can expect them to last longer and maintain their performance. The goal here is to reduce unwanted flex and movement in the rear crossmember, which helps keep your suspension geometry more consistent during spirited driving or hard cornering. This can lead to improved steering response and a more predictable feel from the rear of the car.

This set is designed to fit right into the factory crossmember mounts, making installation more straightforward than replacing the entire crossmember. You'll notice a firmer feel from the rear suspension, which is great for anyone looking to get the most out of their 240SX's handling.
