Radflo vs Fox Coilover Shocks: An In-depth Analysis

Radflo vs Fox Shocks

As we mentioned, both Radflo and Fox have their loyal fan base, but to which group should you belong? Let’s dive into an in-depth analysis of different factors to help you make an informed decision.

External Appearance

Starting with Radflo, their coilover shocks feature a sleek and minimalist design. The shock bodies are typically constructed from high-quality aluminum alloy, which not only provides durability but also helps in dissipating heat efficiently. 

Radflo shocks often come with an anodized finish, giving them a distinct and visually appealing look. Additionally, they sport a visible logo etched onto the shock body, further exemplifying the brand’s attention to detail.

On the other hand, Fox Coilover Shocks have a slightly more rugged appearance. These shocks are often larger and bulkier compared to Radflo’s offerings. However, this is intentional, as Fox prioritizes functionality and performance over aesthetics. 

The shock bodies are commonly made from chromoly steel or aluminum alloy for maximum strength during off-road excursions. Furthermore, Fox’s coilover shocks may feature distinctive design elements such as protective stainless steel shock shaft guards or specialized coatings to enhance corrosion resistance.


To evaluate the durability of these coilover shocks, it is necessary to analyze the quality of their constituent parts. Shocks can experience rapid failure as a result of piston rod and seal damage or gradual deterioration due to seal wear and dirt infiltration. 

So, these elements play a crucial role in determining how well shocks can withstand wear and tear over time.

  • Seals

When it comes to the seals used in shock absorbers, their primary purpose is to ensure that the oil stays inside even under rigorous conditions while minimizing friction. Fox utilizes viton seals, which are widely recognized as the industry standard for high-temperature and low-friction applications. 

This material excels in maintaining its integrity even in extreme temperatures, resulting in the reliable performance of Fox coilover shocks.

On the other hand, Radflo coilovers employ a different seal setup known as Combination Quad-Ring and Lip seals. These seals offer the advantage of being rebuildable, allowing for easier maintenance and potentially extending the lifespan of the shocks.

Radflo’s Choice of Combination Quad-Ring and Lip seals offers versatility, as these types of seals provide multiple sealing surfaces that work together. 

  • Shock Oil

Both types of shocks rely on oil for essential functions such as consistent damping across a range of temperatures, heat conduction, and seal lubrication. However, the difference lies in the specific properties and performance of the oils they utilize.

Radflo shocks take a different approach by incorporating their proprietary Radflo High-Temp Foam Resistant Fluid. Designed with high-temperature endurance, this fluid is an excellent alternative to conventional shock oils. Its unique composition allows it to resist degradation even under extreme conditions.

However, Fox Shocks’ conventional oil is engineered to withstand varying temperatures while delivering reliable damping properties consistently. The high viscosity index of 370 indicates that the oil’s viscosity changes minimally with temperature fluctuations, providing more consistent shock performance. 

  • Piston Rods

 When comparing the piston rods of Fox and Radflo shocks, it is clear that both brands utilize high-quality materials to ensure superior performance. Fox coilover shocks employ 17-4 H900 stainless steel piston rods specially treated with hard chrome plating. 

This not only enhances the overall strength at an impressive tensile strength of 190 ksi but also provides excellent resistance against corrosion.

On the other hand, Radflo offers two options for their piston rods: Nitro Steel or Mirror Polished Chromed Rod with PTFE Coating. The Mirror Polished finish on Radflo’s piston rod adds an aesthetically pleasing element to their product.

Dampening Performance

When it comes to rebound dampening, Radflo shocks exhibit impressive control and adjustability. Their unique valve design enables precise tuning of rebound characteristics to suit individual preferences and vehicle requirements. 

Likewise, Fox shocks offer exceptional rebound dampening capabilities through their proprietary technologies, such as External Bypass Adjusters or Dual Speed Compression Dampening Adjustment.

Compression dampening is crucial for maintaining stability and preventing bottoming out during intense off-road driving. Radflo shocks deliver outstanding compression-dampening performance with adjustable valving options that cater to different needs – from rock crawling to high-speed desert racing. 

Similarly, Fox shocks offer excellent compression dampening control with features like Position-Sensitive Dampening (PSD) technology or Adjustable Reservoirs.

Ride Quality

First up, Radflo. These shocks are known for their superb build quality and ability to handle intense terrain like a champ. With Radflo, you can expect a smooth and controlled ride thanks to their advanced damping technology. 

Radflo shocks are well-known for their precision valving, which allows for unmatched adjustability. Hence, you can fine-tune your suspension for optimal comfort and handling. Now, let’s move on to Fox. These coilovers are popular among off-road enthusiasts due to their excellent performance and reliability. 

What sets Fox apart is their use of advanced nitrogen gas-charged shock technology, providing superior control and stability on rough trails. The adjustable dual-speed compression feature allows you to tailor your ride based on various driving conditions.

When it comes to comparing the two, it’s all about personal preference. Some folks prefer the plush feel of the Radflo shocks, which can deliver a more comfortable ride over uneven terrain. 

On the other hand, those seeking maximum control and responsiveness may lean towards Fox coilovers with their precise tuning capabilities.


Radflo offers a range of options to fit different budgets. Their entry-level coilovers start around $500 per shock, while their top-of-the-line performance series can set you back upwards of $1,000 per shock.

Now, onto Fox. Known for their race-proven technology and durability, Fox has become a go-to brand for many enthusiasts. Price-wise, Fox is generally considered more on the premium side. 

Their standard 2.0 Performance Series coilovers start at around $800 per shock, while their high-end 3.0 Factory Race Series can go as high as $1,200 per shock.
