ReadyLIFT Suspension now offers its first 4-Inch Coil Spring Lift Kit for 2017-2022 Ford Super Duty F250/F350 4WD Power Stroke trucks equipped with new Tubular Radius Arms. This kit, designated as 49-27421, comprises front and rear Falcon 1.1 Monotube series performance shocks, a front track bar relocation bracket, tubular radius arms, and rear fabricated blocks.

It provides an excellent solution for lifting F250/F350 Super Duty trucks to accommodate larger tires, with the coil spring system enabling increased tire sizes and widths while enhancing ground clearance. This lift height strikes the ideal balance for Super Duty driving dynamics and maximum tire size while retaining everyday practicality.

The newly designed Radius Arms address suspension geometry correction for lifted models. These heavy-duty radius arms are engineered to withstand the rigors expected from Super Duty trucks and surpass factory radius arms with added support gussets.

Their inward formation allows for increased tire clearance and the installation of oversized tires, all through a direct bolt-on design that ensures quick and easy installation. This optimal lift height accommodates tires up to 37-Inch in height, delivering an exceptional ride and handling performance.

The key components for improving your ride include specially engineered coil springs, Falcon shocks, and track bar relocation. This combination transcends a mere lift kit, offering both enhanced performance and ride quality on and off-road.

The ReadyLIFT 4-Inch Coil Spring lift kit for 2017-2022 Ford Super Duty trucks also includes model-specific brake line extension brackets, proven bump-stop extension brackets, and new front sway bar frame mount extension brackets to maintain the factory sway bar's correct position. If you seek a rugged appearance and a smooth yet controlled ride, the new Super Duty 4-Inch Coil Spring Suspension Kit System is your answer.

This a great little phone mount. It works for my iPhone 17 pro max. I drive a lot of dirt roads where I live in the mountains, and the magnet holds up to plenty of bumps without dropping my phone. Easy to install. Pros: -very simple installation -strong magnet -arm rotates for adjustment -ball and socket joint allows tilting with a good amount of resistance to hold its position (when fully tightened) Cons: - for model 3 users, anything other than next to the steering wheel can block a portion of your windshield viewing area -could have more modularity if offered with more arm attachments Conclusion: RECOMMENDED. Very stable and functional mount with a minimalistic design that still allows for some adjustability. If magnet weakens over time, or the sun damages the plastic to the point of breaking from brittleness then I will post updates. I will also update for any modifications I make for more adjustability.

This economical solution works perfectly
Color: Black
Very happy with this car mount. The magnet is plenty strong to securely hold my iPhone in its magnetic loop case. It’s plastic but it’s sturdy and fits on my Model 3’s screen perfectly. It has an adjustable height that I can mount my phone with full clearance of my steering wheel. Don’t waste your money on a metal mount, this inexpensive mount serves the need perfectly.

Good option for FSD drivers with a thin skin
Color: Black
Works great. Holds the phone very well and can be repositioned very quickly to accommodate various driving modes like laid back and deep or focus edge of your seat with getting yelled at by FSD (not really self driving)
