Radius Arm Drop Bracket - Rugged Style

F450 8" 4-Link Radius Arm Drop Bracket


We went about it a little different. Instead of the drop bracket going up inside the factory radius arm pocket, we designed ours to mount uniquely outside. That adds width and strength. These features cost more to produce, but the end result is unmatched. All our steel is U.S. made and is at least ¼”, and in some instances even larger.

OPTIONAL SHOCK UPGRADES

Stryker's 3.5" F450 F550 lift kit does not require upgrading your shocks if they are still comfortably within their useful life.

With the shock extension brackets included in this kit the standard F450 F550  Super Duty OEM Shocks can comfortably operate with this 4" lift kit and continue to provide you with that excellent Super Duty ride you expect.

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.

SHOCK OPTIONS

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 F250 F350 Super Duty Truck

Vibration:
Vibration is the primary demand to focus on. The original excellent suspension on your F250  F350 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 F250 F350 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 F250 F350. 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 F250 F350 Lift? Stryker's goal is to provide you with RUGGED STYLE™! We are committed to providing performance and style. Review our V1 and V2 offerings including 4 levels of shock upgrades.
