Prothane Polyurethane Front Sway Bar Bushing Kit – 24mm or 27mm
For 1989–1995 Toyota Pickup 4WD
Overview
Restore the factory handling, steering response, and cornering stability of your 1989–1995 Toyota Pickup 4WD with the Prothane Polyurethane Front Sway Bar Bushing Kit, available for 24mm or 27mm factory front sway bars. Designed as a direct-fit replacement for worn factory rubber sway bar bushings, this kit delivers improved suspension control, reduced body roll, and exceptional durability for daily driving, restoration projects, overlanding, and off-road use.
Factory rubber sway bar bushings naturally deteriorate from age, heat, oil, moisture, road salt, and continuous suspension movement. As they wear, the sway bar can shift excessively, reducing steering precision, increasing body roll, and creating unwanted suspension noise. Prothane's premium polyurethane bushings resist these conditions while maintaining a secure sway bar connection for improved handling and long-lasting reliability.
Because Toyota used multiple front sway bar diameters throughout production—and many trucks have had suspension components replaced over the years—the front sway bar should always be measured before ordering to ensure the correct kit is selected.

Polyurethane vs. OE Rubber: Choosing the Right Bushing for Your Build
When deciding between polyurethane and factory rubber bushings for your restoration, it helps to weigh their performance traits: Polyurethane delivers a dramatic upgrade in handling precision, steering response, and cornering stability by eliminating suspension slop, alongside exceptional resistance to oil, road grime, and dry rot that ensures it will outlast stock rubber many times over. On the flip side, because polyurethane is a significantly firmer elastomer, it transmits a more direct, stiffer road feel and requires proper lubrication during installation (using the included super grease) to prevent squeaking. While OE rubber provides a softer, more isolated ride that absorbs minor road vibrations, polyurethane is the ultimate choice for enthusiasts seeking tighter handling, superior durability, and long-term performance from their classic build.

Choosing the Correct Sway Bar Size
This kit is available for 24mm and 27mm factory front sway bars.
Toyota used multiple sway bar diameters throughout production, and many trucks have had suspension components replaced over the years. Vehicle year, trim level, engine, and VIN cannot reliably determine the correct sway bar diameter.
The only accurate method is to physically measure your front sway bar before ordering.
Easy Measurement Without Calipers
If you don't have digital calipers, you can verify the sway bar size with a standard wrench:
- Clean a straight section of the front sway bar.
- Slide a 24mm open-end wrench over the sway bar.
- If the wrench fits snugly around the sway bar, your vehicle has a 24mm sway bar.
- If the wrench will not fit over the sway bar, your vehicle most likely has a 27mm sway bar.
This quick measurement helps ensure you receive the correct bushings the first time.
Installation Notes
- Measure your factory front sway bar before ordering.
- Fits 24mm or 27mm factory front sway bars only.
- Designed for factory-style sway bars.
- Clean the sway bar and mounting brackets before installation.
- Apply the supplied polyurethane grease to all bushing contact surfaces.
- Inspect sway bar brackets and mounting hardware for wear before reassembly.
- Professional installation is recommended if suspension components are heavily worn.
Available Bushing Colors
Choose the finish that best complements your build.
Black Polyurethane
Provides a clean, factory-inspired appearance that blends seamlessly with OEM suspension components.
Red Polyurethane
Features Prothane's signature performance appearance for enthusiasts who prefer a more noticeable suspension upgrade.
Both black and red bushings are manufactured from the same premium Prothane polyurethane and provide identical fitment, performance, durability, and resistance to oil, grease, chemicals, moisture, and UV exposure. The only difference is color.
