The ICON Vehicle Dynamics 4.5-inch Front Dual Rate Spring Kit is a high-performance suspension upgrade for the 2005-2025 Ford F-250 and F-350 Super Duty 4WD. These springs are engineered to provide a significant increase in ride height while delivering a "best of both worlds" ride quality. The dual-rate design features a softer initial rate to soak up small road chatter and a firmer secondary rate that engages during deeper compression to provide excellent bottoming resistance during aggressive off-road use or heavy hauling.
Features
- 4.5-Inch Lift Height: Provides ample clearance for up to 37-inch tires and creates an aggressive, leveled stance.
- Dual Rate Design: Delivers superior on-road comfort without sacrificing the stability and bottoming control required for off-road performance.
- Shot-Peened & Pre-Set: Manufactured to the highest industry standards to prevent sagging or breakage, ensuring consistent ride height for the life of the truck.
- Increased Wheel Travel: Optimized to work with ICON 2.5 Series shocks to unlock maximum vertical wheel travel.
- Premium Finish: Finished in a durable, dual-stage semi-gloss black powder coat for maximum corrosion resistance against road salts and debris.
- Lifetime Guarantee: Backed by ICON’s lifetime warranty against spring sagging or breakage.
Notes
- Specifically fits 2005-2025 Ford F-250 and F-350 Super Duty 4WD models.
- 2020-2025 Models: Due to factory height changes, these springs may provide closer to 5-5.5 inches of lift on newer trucks.
- Tremor-equipped models will see approximately 3.5 inches of lift over their factory height.
- Optimized for Diesel engine models; gas-equipped trucks will sit slightly higher than the advertised lift height.
- Requires the use of an adjustable track bar or track bar drop bracket to ensure the front axle remains centered.
- Extended brake lines and radius arm drop brackets or aftermarket radius arms are required at this lift height to maintain proper geometry.

It has no sound insulation function at all
Size: 5 Panels, Color: Grey
I purchased this soundproof partition with the expectation of creating an independent and quiet office environment. However, the product does not deliver effective sound insulation. The ambient conversation noise outside the partition measures 50 decibels, and the noise level inside remains unchanged at 50 decibels. Given this lack of performance, I would like to inquire about the actual acoustic value of this partition. This constitutes a clear case of misleading advertising.

Partition Divider
Size: 5 Panels, Color: Grey
The Natwind 5-panel portable partition is ideal for creating privacy and dividing office space. At 122.8" x 71", it provides substantial amount of coverage, and the folding design makes it easy to set up, move, or store as needed. The freestanding structure is stable. The acoustic panels are quite thick at about 1/2in thick and help reduce noise. Its neutral color and design blends well with most office interiors. Overall, this partition is a convenient and effective choice for temporary or flexible workspace layouts.

Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours.
I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.

Easily Create a Workspace
Size: 5 Panels, Color: Grey
Such a great design. I am loving the versatility of these - very easy to set up and also to store. THe color is perfect for them to blend into the decor. While they don't cancel out the noise altogether, they reduce it and decrease distractions. No installation needed - has its own supports. Built really well with good materials - sleek and sturdy and solid. They have increased the privacy and have helped make a great space without difficult construction. Work well and they are great value for money - instant privacy and space.
