What is the main benefit of using polyurethane bushings over rubber?

Polyurethane bushings are generally more durable and resistant to degradation from oils, water, and extreme temperatures compared to standard rubber bushings. This often results in a longer service life and more consistent suspension performance.

Does this kit include all the necessary parts for the rear upper inner control arms?

Yes, this is a kit designed to replace the rear upper inner control arm bushings. It contains the specific Superpro polyurethane bushings needed for that location on your vehicle.

How will replacing these bushings affect my car's handling?

Worn bushings can cause imprecise steering and alignment changes. Replacing them with these Superpro bushings helps to restore proper suspension geometry, leading to more stable handling and a more connected feel to the road.

Product Details

If you're noticing vague steering or uneven tire wear on your 1990-1994 Lexus LS400, worn rear upper inner control arm bushings could be the culprit. These bushings are crucial for keeping your suspension geometry stable, and when they break down, they allow for unwanted movement that affects how your car handles and how your tires wear. This kit from Superpro offers a well-built solution to restore that stability.

Superpro uses a special engineering-grade polyurethane for these bushings, which is a tougher alternative to the original rubber. This material is designed to hold up better against the elements, like extreme temperatures, oil, and water, meaning they'll last longer and keep your suspension working correctly. By stabilizing the control arms, these bushings help maintain proper wheel alignment, leading to improved handling feel and potentially extending the life of your tires.

Designed and made in Australia, this kit is a solid option for repairing or upgrading the rear suspension on your LS400. It's a direct replacement for the factory bushings, making installation straightforward.
