Overview

The Old Man Emu MT64 Rear Shock is designed for 4th-Gen 4Runner owners who need dependable suspension performance across changing road and trail conditions. Developed with overland travel and heavier vehicle setups in mind, it focuses on load handling, controlled damping, and lasting comfort for vehicles that spend long hours on the road and venture well beyond paved routes.

Design

The MT64 features a massive 2.8-inch body that accommodates more oil, supporting damping performance and providing greater flexibility for accurate shock tuning, helping maintain a controlled response across a variety of conditions.

Valving

Digressive valving lets the shock react promptly to changing inputs. This damping approach provides control as road conditions change, helping the 4Runner stay composed on uneven pavement, gravel roads, and off-road terrain.

Construction

The forged body cap and rod ends reduce weight while maintaining strength, contributing to a durable shock without adding unnecessary mass, an important consideration for vehicles carrying camping equipment and other gear.

Comfort

The Old Man Emu MT64 shock is designed to provide smooth, controlled suspension behavior that helps reduce driving fatigue and improve comfort for both the driver and passengers during daily commutes and longer journeys.
