The ICON Vehicle Dynamics 4.5-inch Front Diesel Dual Rate Spring Kit is specifically engineered for the 2023-2025 Ford F-250 and F-350 Super Duty 4WD. These springs are precision-tuned to accommodate the revised chassis and front-end weight of the 6.7L Power Stroke Diesel engine on the newest Super Duty platform. By utilizing a dual-rate design, ICON provides a significant performance upgrade over factory linear springs, delivering a plush ride on the pavement without sacrificing the stability and bottoming resistance required for heavy towing or aggressive off-road use.

Features
  • Diesel Optimized: Specifically tuned for the heavy front-end weight of 2023-2025 diesel models to ensure accurate lift height and optimal spring frequency.
  • 4.5-Inch Lift Height: Provides a commanding stance and the necessary clearance to fit 37-inch tires for increased ground clearance and off-road capability.
  • Dual Rate Design: Features a softer initial rate for superior small-bump compliance and a firmer secondary rate that engages during compression for better handling and bottoming control.
  • Increased Wheel Travel: Designed to work in conjunction with ICON shocks to provide up to a 50% increase in front wheel travel over the factory suspension.
  • Shot-Peened & Pre-Set: Manufactured to the highest standards to increase tensile strength and prevent sagging, backed by a lifetime guarantee.
  • Premium Finish: Finished in a dual-stage semi-gloss black powder coat for maximum protection against corrosion and road debris.
Notes
  • Specifically designed for 2023-2025 Ford F-250 and F-350 Super Duty 4WD models equipped with the Diesel engine.
  • Tremor-equipped models will see approximately 3.5 inches of lift over their factory height.
  • Requires the use of ICON or other aftermarket radius arms or radius arm drop brackets to maintain proper front-end caster and geometry.
  • An adjustable track bar or track bar drop bracket is mandatory to ensure the front axle remains centered at this lift height.
  • Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation.

Kids?
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
