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

Polyurethane bushings are generally more durable and resistant to degradation from heat, road chemicals, and stress than traditional rubber. This means they can last longer and maintain their performance characteristics over time, providing a more consistent feel.

Do these bushings come with new hardware?

This kit includes the polyurethane bushings only. You will need to reuse your original transmission mount hardware or source new hardware separately if needed.

Will these bushings fit my 2WD truck?

No, these transmission mount bushings are specifically designed for 4WD (four-wheel drive) models of Chevrolet and GMC trucks from 1968-1984. They are not compatible with 2WD applications.

Product Details

When you're tackling drivetrain repairs on your classic Chevy or GMC 4WD truck from '68 to '84, replacing worn transmission mount bushings is a key step. These Prothane bushings are made from a durable polyurethane material that helps absorb vibrations and shock, giving you a more solid feel from your drivetrain. They are designed to replace the stock rubber bushings that can degrade over time, leading to excessive movement and noise.

This set is specifically for the transmission mount on 4WD models, ensuring a proper fit and function. Polyurethane is known for its resilience and ability to withstand the stresses of daily driving and off-road use, offering a long-lasting solution compared to original rubber components. Installing these will help reduce that clunking or excessive flex you might feel when shifting gears or accelerating.

This kit fits a wide range of K10, K20, K30, K5 Blazer, and GMC Jimmy, K1500, K2500, and K3500 models from the late 60s through the mid-80s. Make sure to check the fitment details to confirm compatibility with your specific truck.
