Overview

The Old Man Emu Rear Coil Spring X-Hvy is engineered specifically for Jeep Wrangler models from 2007 to 2018 equipped with 3.6L and 3.8L V6 engines. Designed to handle the increased load demands of serious off-road and remote area travel, these coil springs provide enhanced support for vehicles carrying heavy gear such as fuel, water, spares, and safety equipment. By upgrading your suspension with these springs, you gain improved ride height and superior ride control, ensuring your Wrangler remains stable and responsive even under full load conditions.

Ideal for 4WD enthusiasts who require reliable suspension performance during extended trips, the Old Man Emu Rear Coil Spring X-Hvy is part of a comprehensive suspension system that can be fine-tuned when paired with matching Old Man Emu shock absorbers. This integration delivers a balanced and controlled ride tailored to your vehicle’s specific needs.

Key Features

These rear coil springs incorporate advanced design principles to optimize load capacity and ride quality. Key features include:

• Extra heavy-duty (X-Hvy) rating for superior load carrying capability
• Engineered specifically for Jeep Wrangler JK models (2007–2018) with 3.6L and 3.8L V6 engines
• Increased ride height to accommodate larger tires and improve ground clearance
• Enhanced ride control to reduce body roll and improve handling under load
• Designed to work seamlessly with Old Man Emu shock absorbers for a fully integrated suspension system
• Durable construction to withstand harsh off-road conditions and heavy use
• Precision wound coils for consistent spring rate and long service life
• Corrosion-resistant finish to protect against environmental damage

Construction & Design

Old Man Emu coil springs are manufactured using high-quality steel alloys selected for their strength and resilience. The springs undergo a rigorous winding process to ensure uniform coil spacing and consistent spring rates, which translates to predictable and stable suspension behavior. The extra heavy-duty rating means these springs are thicker and stiffer than standard coils, providing the necessary support for heavily loaded vehicles without compromising ride comfort.

Each spring is treated with a corrosion-resistant coating to extend its lifespan, especially important for vehicles exposed to mud, water, and salt during off-road adventures. The design philosophy focuses on balancing load capacity with ride quality, ensuring that your Jeep Wrangler maintains excellent handling characteristics even when fully loaded.

Installation & Fitment

Installation of the Old Man Emu Rear Coil Spring X-Hvy is straightforward for experienced mechanics and off-road enthusiasts familiar with suspension upgrades. These springs are direct replacements for the factory rear coils on Jeep Wrangler models from 2007 through 2018 with 3.6L or 3.8L V6 engines. No major modifications are required, but it is recommended to have the vehicle professionally aligned after installation to optimize handling and tire wear.

For best results, pairing these springs with Old Man Emu shock absorbers is highly recommended to achieve a fully integrated suspension system tailored to your vehicle’s load and terrain demands.
