New Window RAD Lift KIT on Diesel Brothers F450 Night Train
Diesel Brothers RAD LIFT KIT on Night Train

4.5" F450 F550 Lift Kits released in our newest generation of suspension lifts! Our RAD” series (Radius Arm Drop) series. This new 4.5" 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!

We address everything needed for your 4.5" F450 F550 Lift Project in this kit. By utilizing a spacer, your Super Duty truck retains  the factory-spec’d coils, thus retaining the factory-like 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. Our 4.5" F450 F550 drop brackets for the radius are the beefiest in the industry!

We went about it a little different with this 4.5" F450 F550 Lift Kit. 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 to your 4.5" F450 F550 Lift. 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. We offer several shock options on this line.

Our "BOLT" series is an affordable option for your 4.5" F450 F550 Lift Kit project that retains all of our Rugged Off Road Design benefits  but offers a lower cost with the removal of our Identity Series RAD (Radius Arm Drop) Badge Kit.

OPTIONAL SHOCK UPGRADES

Stryker's 4.5" 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 4.5" 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

Stryker ORD-Level 1

 

Ford F250 F350 Steering Stabilizer L1 Shocks

 

 

Stryker's ORD (Off Road Design) Level 1 Shock upgrade are a silver powdered 2.0 body with a nice decal (color coated to the lift options you choose). These offer 10-stage variable valving and are a nitrogen charged shock. This is a great shock for the money. With the variable valving, these can react to on road and off road conditions. They offer a great ride and carry a 3-year warranty!

 

Stryker ORD-Level 2 Bilstein

  

Ford F250 F350 Steering Stabilizer Bilstein Shocks

This Stryker ORD Level 2 Shock upgrade is a special ordered Bilstein monotube shock that we stock exclusively for our kits. These deliver the performance Bilstein is known for. We took this shock to another level by taking the existing zinc plating, adding our own 3M clear protective film (as we found their zinc plating just wasn’t enough protection), then we choose a decal color that matches the lift color options you chose.


Stryker ORD-Level 3 Monotube

Stryker Level 3 Monotube Steering Stabilizer Shocks

 

Stryker Level 3 Shock Recommendation

Stryker's ORD Level 3 Monotube Shocks are a T6061 brushed aluminum bodied MONOTUBE shock. They represent an OUTSTANDING combination of Ride Quality coupled with true Heavy Duty Performance when required.

These would best be described as equivalent to a Fox monotube for performance but with the added value of carrying a THREE YEAR Warranty and a clean uncluttered brushed aluminum look!

They have an internal floating piston for a very consistent performance. With the T6061 brushed aluminum body, these bodies can never rust.  With this combination of performance and value this shock option carries the STRYKER-HIGHLY-RECOMMENDED classification for this DSS kit!

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 and V2 offerings including 4 levels of shock upgrades.
