AE86 Prothane Polyurethane Front Sway Bar Bushings Kit (1983-87 Corolla)

Prothane Polyurethane Front Sway Bar Bushing Kit –  21mm or 22mm

For 1983–1987 Toyota Corolla AE86 Trueno & Levin SR5, GTS and All JDM Trims

Restore the factory handling characteristics of your AE86 with the Prothane Polyurethane Front Sway Bar Bushing Kit, engineered specifically for 1983–1987 Toyota Corolla AE86 Levin, Sprinter Trueno, SR5, GT-S, and all JDM models. Designed as a direct replacement for worn factory rubber bushings, this kit helps maintain proper front sway bar alignment while improving steering response, reducing body roll, and delivering more consistent suspension performance.

Manufactured in the USA from premium Prothane polyurethane, these bushings are designed to withstand oil, grease, chemicals, moisture, road salt, ozone, and UV exposure. Unlike aging rubber bushings that soften and compress over time, polyurethane maintains its shape under load, resulting in improved sway bar performance, more precise handling, and a significantly longer service life.

This kit is available for 21mm or 22mm factory-style front sway bars found on 1983–1987 Toyota Corolla AE86 models. Because many vehicles have received suspension modifications throughout their lifetime, always measure your front sway bar diameter before ordering to ensure proper fitment.

These factory sizes are provided as a general reference only. Previous repairs, aftermarket suspension upgrades, or sway bar replacements may have changed the bar diameter. Always measure before ordering.

Measure Before Ordering

This kit fits either a 21mm or 22mm front sway bar, depending on the option selected.

Because many AE86s have received replacement or aftermarket suspension components over the years, vehicle year, trim level, engine, or VIN should never be used as the sole method of determining sway bar size.

Measuring With Calipers

1. Clean a straight, rust-free section of the front sway bar.
2. Measure the outside diameter using digital calipers.
3. Select the kit that matches your measurement:
   • 21mm
   • 22mm

Measuring Without Calipers

1. Clean a straight section of the sway bar.
2. Slide a 21mm open-end wrench over the bar.
3. A snug fit generally indicates a 21mm sway bar.
4. If the wrench does not fit, verify whether your vehicle has a 22mm sway bar.

Do not measure over bends, mounting sleeves, rust buildup, paint, or damaged sections of the sway bar.

Installation Notes

• Fits factory-style 21mm or 22mm front sway bars only
• Measure the sway bar before ordering
• Thoroughly clean all mounting surfaces before installation
• Remove rust, dirt, old grease, and deteriorated rubber residue
• Apply the supplied polyurethane lubricant to all recommended contact surfaces
• Inspect sway bar brackets, end links, sleeves, and mounting hardware for wear or damage
• Replace bent, corroded, or excessively worn hardware as necessary
• Tighten all fasteners according to the Toyota Factory Service Manual
• Professional installation is recommended when working with seized or heavily corroded suspension components
