Prothane Polyurethane 18mm Rear Sway Bar & End Link Bushing Kit (1990-95 4Runner)

Prothane Polyurethane Rear Sway Bar & End Link Bushing Kit – 18mm

For 1990–1995 Toyota 4Runner 2WD and 4WD with a Factory 18mm Rear Sway Bar

Overview

The Prothane Polyurethane Rear Sway Bar & End Link Bushing Kit replaces the factory rubber rear sway-bar mounting and end-link bushings on 1990–1995 Toyota 4Runner 2WD and 4WD models equipped with a factory 18mm rear sway bar. Both applications require a factory 18mm rear sway bar with its original matching mounting clamps and links.

The firmer polyurethane bushings help reduce unwanted movement between the rear sway bar, chassis mounts, and end links, allowing the sway bar to operate more consistently during cornering and directional changes. Polyurethane also provides increased resistance to deterioration from age, weather, road grime, and automotive fluids compared with conventional rubber bushings.

Before purchasing, measure your rear sway bar and confirm it is 18mm.

Choosing the Correct Sway Bar Size

This kit is designed specifically for an 18mm rear sway bar. The frame bushings must closely match the bar diameter to properly locate the sway bar without excessive clearance or binding.

Digital or vernier calipers provide the most accurate measurement. An 18mm open-end wrench can also be used as a quick check on a clean, straight section of the bar, but calipers are recommended if the fit is uncertain.

Do not measure over heavy rust, thick paint, a bend, sleeve, or damaged section of the sway bar.
