ReadyLIFT Suspension is pleased to announce a new Super Duty lift kit. We are now offering our first 4-Inch Coil Spring Kit including Tubular Radius Arms, Falcon Dual Steering Stabilizer and the new Falcon 3.3 piggyback shocks.

This gives Super Duty owners an excellent alternative for lifting their trucks to fit larger tires. The coil spring system allows for increased tire sizes and widths along with providing improved ground clearance on a head-turning stance!

Many consider this lift height the sweet spot for Super Duty driving dynamics and maximum tire size while maintaining everyday usefulness.The all-new Radius Arms are designed to correct the suspension geometry on lifted models. These new radius arms are heavy duty and are built to handle the use and abuse demanded out of Super Duty trucks.

The new radius arms hold up to the abuse and surpass the factory radius arms and support gussets. The arms are formed inward, allowing for additional tire clearance, and providing the ability to install oversized tires.

The direct bolt-on design promotes quick and easy installation.With the help of Falcon steering dampers ReadyLIFT's new Dual Steering Stabilizer provides superior truck stability which is crucial for any solid front axle vehicle equipped with oversized-sized tires. Falcon steering stabilizers allow for more confident handling over the road and in challenging terrain.

They reduce bump steer and improve steering feed contributing to overall truck comfort and security thanks to the increased truck maneuverability and control.This optimum lift height allows for up to 37-Inch tall tires. The coil spring kit delivers a great ride and handling performance!

The key ingredients to improving Super Duty ride and handling are the new, specially engineered coil springs teamed with Falcon 3.3 shocks and a track bar relocation bracket! This combination is more than just a lift kit, this is a performance and ride-enhancing kit that will really delight consumers with how well it rides and performs both on and off-road.

Great toothbrush! Bought in january2025(it’s December 2025 now) Yay!
Color: Light Blue, Color: Light Blue
I bought this electric toothbrush in January of this year (2025) and it still works Great!! I bought it for my son and he brushes his teeth at least twice a day, sometimes more (he has gotten a hold of it a couple times and was trying to brush his stuffed animals mouth with it..haha..) and it is still going strong!! The battery life lasts Super good!! I don’t even remember the last time I charged it.. I love that it comes with multiple tooth brush heads to switch it out with and there are different settings to choose to brush with like soft, clean, massage, ect. I like the baby blue color because I bought it for my son. We have traveled and moved with this tooth brush and I am Super happy with it and would Definitely recommend!! Great price too!! Good power, gets teeth nice and clean!! And it’s a good size for my toddler/young son.

Great electric toothbrush
Color: Light Blue
Had for over a year for my kid. The timer is amazing. It’s set in 4 - 30 second increments to help get a better clean. Battery is pretty long lasting. I’ve only charged maybe 3-4 times and he brushes twice a day. Super easy to use even for him. Love that it comes with extra heads. Would definitely buy again.
