Drive Quality

- Yes, it significantly improves! When a vehicle like the PV5 Cargo is heavily loaded, the rear sags, which reduces steering precision and compromises ride comfort as the suspension bottoms out. By installing the 1.5-inch Bigfoot lifting springs, you restore the effective suspension stroke. This allows the vehicle to absorb road impacts much better, reduces body roll during cornering, and provides a much more stable and planted feel even under full load.


Consumer Feedback in Korea 

- In the Korean market, Bigfoot is widely regarded as the gold standard for heavy-duty springs. It is exceptionally popular among owners of camper vans, mobile workshops, and delivery vehicles. Common feedback includes: "The car no longer feels like it's squatting under weight," "High-speed stability has improved drastically," and "It provides a much firmer, more reliable ride than the OEM springs." It is highly trusted for its durability and performance under pressure.

Stop the Rear Sag! Improve Your PV5 PASSENGER’s Handling & Balance

Does your PV5 PASSENGER feel a bit "light" in the steering when loaded up? When the rear sags due to heavy cargo or passenger, it lifts the front end, reducing tire grip and compromising your safety.
Bigfoot Heavy-Duty Springs are the solution. Specifically engineered for the PV5 PASSENGER, these springs provide:
  • 1.5-Inch Lift: Restores the ideal ride height even under load.
  • Enhanced Front Grip: Keeps your front tires planted for better steering and traction.
  • Perfect Balance: Eliminates the "squatting" look and improves overall driving stability compared to stock springs.
Don't settle for a bouncy, unbalanced ride. Check out the product details in the link below and upgrade your driving experience!

To provide you with a clearer understanding of our product..,

- Progressive Design vs. Linear Design:
You may notice these are not linear springs. In the case of the PV5 PASSENGER, the spring's outer diameter is quite large while the free length is short and the number of coils (turns) is limited. These physical constraints make a Linear Design impractical for performance. Instead, we utilize a Progressive (Variable Rate) Design. This allows the spring to remain compliant for a smooth ride during daily driving, while rapidly increasing resistance as the load increases to prevent bottoming out.

- Key Engineering Focus
Front Suspension: As shown in the data, the front isn't just about "stiffness." We focused on material and design changes to achieve both a lift and a significant improvement in ride comfort.

Anti-Sagging Performance: The core strength of Bigfoot springs is their long-term Anti-Sagging durability. They are engineered to maintain their height even under constant heavy loads over many years.

Why Korean Users Choose Bigfoot: In Korea, even owners who don't carry heavy loads consider these springs essential. They eliminate the "floaty" feel of the stock suspension, providing a much more planted and stable driving experience.

We are confident that once you install these, you will feel the difference in stability. We look forward to your feedback.

 

Consumer Reviews: Bigfoot Lifting Springs for PV5 PASSENGER

  • The Ultimate Solution for Rear Sagging: There is overwhelming praise for how these springs prevent the rear from "bottoming out" even when the vehicle is fully loaded with camping gear or towing a caravan. Because they have a higher spring rate than the OEM (factory) setup, they are excellent at maintaining ride height under heavy loads
  • Enhanced High-Speed Stability: By reducing "rear squat" (the rear dipping during acceleration or high speeds), the car feels much more planted and solid on the highway. Many users also report a reduction in body roll, which has helped alleviate motion sickness for passengers in the 2nd and 3rd rows.
  • Cost-Effectiveness and Durability: Compared to expensive coilovers or full suspension replacements, these offer great value. Since they are manufactured by Storm Springs (a reputable Korean brand), they are optimized for local road conditions and have a high reputation for long-term durability.
