What Are Old Man Emu Coil Springs?
Old Man Emu (OME) coil springs are high-performance suspension components designed to provide a lift and improve the ride quality and load-carrying capabilities of 4x4 vehicles. Developed by ARB, these springs are engineered using advanced metallurgy and manufacturing processes to withstand demanding off-road conditions while maintaining predictable handling and comfort on-road. They are a cornerstone for serious off-roaders seeking robust suspension solutions.
- OME springs provide consistent vehicle lift.
- They improve load capacity and suspension durability.
- Engineered for superior off-road performance.
- Enhance both ride comfort and handling.
OME Spring Design and Benefits
The primary benefit of OME coil springs lies in their ability to deliver a specific amount of lift, often paired with increased spring rates. This allows for larger tires and improves approach, departure, and breakover angles, crucial for off-road articulation. Unlike generic springs, OME designs are application-specific, meaning a set intended for a Toyota Tacoma leaf springs upgrade or a Jeep Cherokee XJ leaf springs replacement will be tailored to that vehicle's weight distribution and intended use. This precision ensures the suspension performs optimally, avoiding common issues like premature sagging or harsh ride quality often found with less specialized components.
When to Consider OME Coil Springs
You should consider Old Man Emu coil springs when your vehicle's stock suspension struggles to cope with added weight from accessories like winches, bull bars, or rooftop tents. They are also ideal if you require increased ground clearance for tackling rough trails or if you're looking for a more controlled and comfortable ride, especially when carrying loads. This is a fundamental upgrade for anyone serious about their vehicle's off-road prowess and durability.
Such precision is paramount for achieving predictable suspension behavior.
Choosing the Right OME Springs for Your Needs
Vehicle-Specific Applications
Selecting the correct Old Man Emu coil springs begins with understanding your vehicle's make, model, and year. ARB provides detailed charts and recommendations, ensuring compatibility. For instance, a Jeep XJ leaf springs application might require a different spring length and rate than what's suitable for an E250 Ford van rear leaf springs setup, even if both need enhanced rear load support. The OME range covers many popular 4x4s, offering various lift heights and load ratings to match specific user requirements, from mild daily drivers to heavily equipped expedition vehicles.
Choosing the right springs ensures you don't over or under-build your suspension.
Load Ratings and Lift Heights
OME springs are categorized by their load ratings (e.g., constant load) and the intended lift height. A common mistake is selecting springs based solely on desired lift without considering the vehicle's actual weight. For example, if you're fitting heavy-duty bumpers and a winch, you'll need springs designed for a constant load. Conversely, a vehicle with minimal accessories might opt for a medium load rating to avoid an overly stiff ride. Our analysis indicates that matching load ratings accurately prevents bottoming out and maintains proper vehicle stance.
Always factor in the total weight of planned accessories when selecting OME springs to ensure optimal performance and longevity.
Comparing Lift Springs
While the focus is on OME, it's useful to know how they compare. Generic 'lowering springs' found for vehicles like the 350z lowering springs or 370z lowering springs aim for a different outcome entirely, reducing ride height and stiffening the ride for on-road performance. Similarly, specialized springs like 2008 Aston Martin V8 Vantage lowering springs or Infiniti M37x lowering springs are performance-tuned for sports cars. Old Man Emu coil springs, however, are purpose-built for increased travel, load support, and off-road articulation, a distinct category from street-oriented performance springs.
Installation and Maintenance of OME Springs
Professional Installation Recommended
Installing coil springs involves significant forces and specialized tools. While some experienced DIYers might tackle this, professional installation by a qualified mechanic or suspension specialist is highly recommended. Incorrect installation can lead to dangerous instability, damage to other components, or premature spring failure. This is especially true when dealing with the compressed nature of springs; safety is paramount. Remember, this is not like swapping out used tires Springfield.
The correct installation of OME springs is as critical as their engineering for achieving optimal off-road performance.
Maintenance Best Practices
Old Man Emu coil springs are designed for durability, but regular maintenance ensures they perform reliably for years. The primary 'maintenance' involves periodic inspections. Check for any signs of damage, corrosion, or unusual wear. Ensure the spring seats are clean and free of debris that could cause noise or damage. Inspect shocks and bump stops, as they work in conjunction with the springs. Following the manufacturer's guidelines for inspection intervals will help you identify potential issues early.
Clean your springs and surrounding suspension components during regular washes to prevent salt and debris from causing premature corrosion, especially after off-road excursions.
Common Issues and Troubleshooting
The most common issues with aftermarket springs, including OME, often stem from incorrect installation or selecting the wrong spring for the vehicle's load. If you experience excessive bouncing, harsh impacts, or premature sagging, re-evaluate your spring choice and installation. Ensure all related suspension components (shocks, bushings, sway bars) are in good condition and properly adjusted. For instance, if you replaced Jeep Cherokee XJ leaf springs or Toyota Tacoma leaf springs and notice issues, re-check the associated U-bolts and mounts.
