Prothane Complete Polyurethane Suspension Bushing Kit
For 1984–1989 Toyota 4Runner 4WD
Overview
Restore the handling and suspension performance of your 1984–1989 Toyota 4Runner 4WD with the Prothane Complete Polyurethane Suspension Bushing Kit. Engineered as a comprehensive suspension refresh, this Prothane Total Kit replaces worn factory rubber bushings with premium polyurethane components that deliver improved steering response, tighter suspension control, and exceptional long-term durability.
As factory rubber bushings age, they become soft, cracked, and compressed, leading to excessive suspension movement, vague steering, and inconsistent handling. Prothane's precision-molded polyurethane bushings are designed to resist compression, chemicals, oil, and environmental wear while maintaining the controlled flexibility needed for both daily driving and off-road adventures.
This complete suspension kit includes the most commonly replaced suspension bushings for your first-generation Toyota 4Runner, providing a cost-effective solution for restoring suspension performance without purchasing multiple individual bushing kits.
Available in black or red polyurethane, both versions provide identical durability and performance. Color selection is strictly a matter of personal preference.

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.
