We address everything in this kit. Our 4 1/2" Stryker Ride coils with the Identity Series top spacer are designed to mimic the factory specs and provide a great ride. Our rear blocks have the bumpstop pads built in to utilize the factory rear bumpstops that Ford designed in for the heavy hauling these trucks were designed for. 

We went about it a little different. Instead of offering a leaf adder option we chose to raise the height of your existing leaf springs. Stryker Engineering found that manipulating the OEM Factory Springs resulted in a reduced ride experience for 4 1/2" F450 F550 Lift Kits released in our newest generation of suspension lifts! Our “RAD” series (Radius Arm Drop) series. This new 4 1/2" F450 F550 RAD Series line is the perfect balance between those that need an extremely rugged suspension lift, yet still want it to be stylish! 

SOWN BELOW IS A 2022 F250 WITH 4 1/2" STRYKER RADIUS ARMS LIFT KIT SHOWN WITH THE OPTIONAL 3 1/2" IDENTITY DROP BRACKET INSTALLED AS A REFERENCE INSTALLATION.

OPTIONAL SHOCK UPGRADES

Stryker offers shock upgrades if your driving conditions exceed the standard OEM shocks sweet spot for off road terrain or towing or if your shock is nearing its useful expected operating life. The industry consensus is that with heavy use, you could be looking to replace them at 40,000 or 50,000 miles or sooner. Under normal conditions, 75,000 to 90,000 miles might be reasonable. We have provided a range of shocks for you to consider.

DUAL STEERING STABILIZERS

There is no consensus regarding single versus dual steering stabilizers. But lifted truck projects are usually accompanied with larger tire sizes.

Larger tires bring a variety of physical demands for your F450 F550 Super Duty Truck

Vibration:
Vibration is the primary demand to focus on. The original excellent suspension on your F450  F550 can accommodate most of that vibration. But if you improve the handling and ride quality by dampening the added side to side motion of your tires that is the first place to address. Shock absorbers dampen the up and down movement of your Super Duty and they can also dampen the side movement of your larger tires.

Dual Versus Single:
Dual stabilizers dampen the vibrations better than a SINGLE shock tied to one side in OUR opinion. Is the improvement worth the added cost? 

Of course it depends on several subjective INFORMED decisions. If your Lifted Super Duty is actually a daily driver then the performance improvement may not be required. But if you plan to build your F450 F550 with the capability of HEAVY OFF ROADING even if you don't go there then DUAL is likely your best investment. The cost ADDER is actually not significant compared to the value of your F450 F550. If your lifted truck has tires 35" or larger you are an excellent candidate to investigate a Steering Stabilizer even if Off Road is not a concern!. 

And then there is the subjective issue of STYLE! What did you want to look at when you see the front of your F450 F550 Lift? Stryker's goal is to provide you with RUGGED STYLE™! We are committed to providing performance and style. Review our V1  offerings including 4 levels of shock upgrades.
