ARB | OME Leaf Spring Bushing Sleeve Reducer
For 1984–1989 4WD Toyota 4Runner & 1979–1988 4WD Toyota Pickup
Overview
The ARB Old Man Emu Leaf Spring Bushing Sleeve Reducer is a precision-machined steel insert designed for use with Old Man Emu leaf spring systems on 1979–1989 Toyota Pickup and Toyota 4Runner models equipped with 4WD. This sleeve installs inside the front main-eye polyurethane bushing of compatible Old Man Emu leaf springs, reducing the bushing's internal diameter to properly accept the factory Toyota mounting bolt.
When installing Old Man Emu leaf springs with OME polyurethane bushings, this reducer sleeve provides the correct fitment between the larger aftermarket bushing and the factory 14mm Toyota spring eye bolt. Proper fitment helps maintain suspension alignment, eliminate unwanted movement, and ensure correct clamping force at the front spring hanger.
Designed as a critical suspension installation component, this sleeve is required when using compatible Old Man Emu leaf spring applications.
Purpose-Built Suspension Hardware
The sleeve reducer serves an important role within the leaf spring mounting system.
Function Benefits
-

Why Only Two Are Required?
A typical rear leaf spring suspension uses two leaf spring packs—one on the driver side and one on the passenger side.
Each leaf spring contains:
Front Spring Eye
-
Fixed frame hanger location
-
Requires the sleeve reducer
-
Uses factory Toyota 14mm mounting bolt
Rear Spring Eye
-
Shackle-mounted location
-
Utilizes larger greasable shackle pins
-
Does not require a sleeve reducer
Because only the front spring eye uses the factory 14mm bolt, only two sleeve reducers are required per vehicle.

Designed to install directly into compatible Old Man Emu polyurethane spring eye bushings.
