Energy Suspension 89-94 Nissan 240SX (S13) Black Rear Subframe Insert Set - a supplement to the subf

If you're looking to firm up the rear end of your 1989-1994 Nissan 240SX, these rear subframe inserts from Energy Suspension are a solid option. They work with your existing subframe components to reduce unwanted movement during acceleration and braking. This helps keep your alignment steady and makes a noticeable difference in how the car handles, especially when you're getting on the gas.

These inserts are made from Energy Suspension's Hyper-Flex polyurethane, a well-known material in the performance suspension world. They're designed to supplement your stock subframe bushings, meaning you'll reuse the original outer shells and hardware. The main benefit here is a significant reduction in wheel hop, which is that annoying tendency for the rear wheels to bounce under hard acceleration. You'll also notice improved stability and better control during cornering and braking.
