Quigley's Ford van 4x4 conversions are renowned for their durability and versatility, and Shockwarehouse often gets requests from customers with Quigley conversions on their Ford E-350 vans. On most vehicles, shocks should be inspected and replaced at 50,000 miles. However, the life of a shock on a modified off-road van can be much shorter. Whether you're looking to replace your Quigley E-350's shocks with soft, comfortable factory or high-performance shocks, we have you covered.

For almost half a century, Quigley has converted Ford vans and trucks to 4WD. There are more than 15,000 converted vans out there, and many "Quigley" vans have been modified after they left the Quigley factory or were built by third-party installers, so fitment is not guaranteed. This guide should be considered something other than definitive. You will need to measure your shocks to ensure proper fitment. You can find our guide on how to measure shocks here.

Understanding Quigley Van Shocks

A Look at Quigley's Renowned Versatility

Quigley vans, particularly the Ford E-350 conversions, are known for their superior versatility. They are engineered to handle rugged terrain and demanding weather conditions, making them ideal for off-road enthusiasts and adventurers. The Quigley 4x4 conversion improves the capabilities of the already robust Ford E-350 van by adding four-wheel drive functionality.

One key component contributing to this versatility is the shock absorbers. They are designed to absorb and dampen the impact of rough roads, ensuring a smooth and comfortable ride regardless of the terrain. The Quigley conversion uses high-quality shocks that can withstand the rigors of off-road driving, offering drivers both comfort and control.

However, like any other vehicle part, shocks can wear out over time, particularly under strenuous usage – and Quigley vans are often put to the test. Owners must understand the signs of wear and know when to replace these vital components. Only then can you continue to enjoy the renowned versatility and performance of your Ford E-350 Quigley van.

When to Inspect and Replace Your Shocks

Shock absorbers are critical to your Ford E-350 Quigley van's ride comfort and control. However, they don't last forever. Recognizing the signs of worn-out shocks is crucial to maintain your van's performance.

If your vehicle has traveled over 50,000 miles, it may be time for a shock inspection. However, the specific mileage can vary depending on your driving habits and the conditions your van has been exposed to.

Indications of worn-out shocks include a noticeable decrease in handling and braking performance, excessive bouncing or swaying during rides, or if your van leans or dips during turns or braking. Oil leaks from the shock or strut body or uneven tire wear can also signal the need for shock replacement.

Regular shock inspection and replacement are essential to preserve the performance and comfort of your Ford E-350 Quigley van and ensure safety. Worn-out shocks can increase stopping distance, reduce turn stability, and lead to increased wear on other suspension components. By staying on top of shock maintenance, you can continue enjoying your Quigley conversion's full capabilities.

Considering Your Shock Options

The Comfort of Factory Shocks

Factory shocks, known as OEM (Original Equipment Manufacturer), are installed on your Quigley van when it first leaves the factory. These shocks are designed to provide a good balance of comfort, control, and durability. They're calibrated to work well with the specific vehicle model's weight, geometry, and suspension design, ensuring a smooth, comfortable ride in most driving situations.

The primary advantage of factory shocks is their balance of performance and comfort. They're neither soft nor hard, making them ideal for everyday driving. Due to their less aggressive damping profiles, factory shocks have a longer lifespan than performance shocks.

However, factory shocks are not designed for extreme off-road use or heavy towing. If your Quigley van often faces these conditions, consider upgrading to high-performance shocks. But for regular driving, factory shocks are a reliable and comfortable option.

The Advantages of High-Performance Shocks

High-performance shocks are an excellent option for those who regularly push their Quigley vans to the limit. Whether you often drive on challenging off-road trails, frequently carry heavy loads, or want improved handling, high-performance shocks can significantly improve your van's performance.

These shocks are designed with superior damping and stronger materials to handle harsh conditions better than factory shocks. They can provide a heightened road feel, improved cornering, and less body roll, resulting in a more controlled, responsive driving experience.

High-performance shocks like the Bilstein 4600 series or the Bilstein 5165 remote reservoir shocks offer advanced technology for exceptional performance. For instance, Bilstein's monotube design ensures consistent performance under demanding conditions, while the remote reservoir increases damping power during extended off-road use.

However, it's important to remember that high-performance shocks can make your ride firmer, which some drivers might find less comfortable for everyday driving. But the trade-off can be well worth it for those seeking the ultimate off-road capability and control.

Navigating Your Quigley's History

The Evolution of Quigley Conversions

Quigley conversions have a rich history, dating back to the company's founding in the late 1960s. Over the decades, Quigley has become a trusted name in 4x4 van conversions, particularly for Ford E-series models.

In the early years, Quigley started with simple modifications, primarily converting vans for use in industries like telecommunications, where off-road capability was essential. However, as the demand for off-road vehicles grew among outdoor enthusiasts and explorers, Quigley offered more comprehensive conversions.

Today, Quigley conversions are renowned for their robust off-road capabilities. They have evolved to include improvements in ride quality, handling, and load-carrying ability. The company has continuously refined its conversion process to offer better performance and reliability, including using high-quality shocks.

Understanding the evolution of Quigley conversions can help you appreciate the quality of your van and make informed decisions when it's time to replace parts like shocks. Whether your Quigley is an older model or a more recent conversion, it carries a legacy of off-road capability and durability.

Understanding Third Party Modifications

Over time, some Quigley van owners may opt for third-party modifications to further customize their vehicle's performance, often to suit specific off-road or cargo needs. These modifications range from more prominent tires and lift kits to upgraded suspension components, including shocks.

While such modifications can improve certain aspects of your Quigley van's performance, they can also affect the compatibility and fitment of replacement parts. For instance, if your Quigley van has been lifted, it may require longer shocks than the original factory-installed ones.

Consequently, it's essential to consider any third-party modifications when selecting replacement shocks. You'll need to ensure the shocks you choose are compatible with your van's current setup. If you need clarification on what shocks to get, consider consulting with a trusted shock provider or a professional mechanic experienced with Quigley conversions.

Remember, maintaining or improving your Quigley van's performance is the ultimate goal. Any modifications, including shock replacements, should contribute to this end, not detract from it.

Measures for Ensuring Proper Fitment

Using Guides to Measure Your Shocks

Proper fitment is a crucial factor when replacing your Quigley van's shocks. A shock that's too long may bottom out and damage the shock or your vehicle, while one that's too short might limit suspension travel.

To ensure proper fitment, you'll need to measure your current shocks. Start by ensuring your van is on level ground and at its standard ride height. Measure the distance from the upper shock mount's center to the lower mount's center. This measurement is your current shock's installed or ride height.

You should also measure your shock's fully extended and fully compressed lengths. To do so, you'll need to jack up your van until the wheel is off the ground for the extended length and then let the suspension hang as far as it goes for the compressed length.

These measurements will help you select the correct shock for your Quigley van. Many shock manufacturers and suppliers, including Shockwarehouse, provide detailed fitment guides to help you find suitable shocks based on these measurements.
