King OEM Performance Series 2.5 Front Coilover Conversion Features:

Capable to drive over any terrain type
Simple bolt-on installation
Improves performance
Internal Monotube Design
Dampens shock movement
Comes with necessary hardware

Improves Suspension Response, Articulation, and Wheel Travel while Reducing Fade

Coilover conversions are some of the most extreme and powerful suspension modifications that you can make to your F250/F350 Super Duty truck, and King manufactures some of the highest-quality and best-performing Super Duty off-road coilovers on the market. King's OEM Performance Series Coilovers are also some of the most heavy-duty systems on the market and are each designed from the ground up to deliver unmatched performance and toughness so that you can take your aggressive off-road ready Super Duty truck just about anywhere. King's Coilovers even feature a remote-mounted reservoir which improves heat dissipation and cooling for greatly reduced fade under even the most intense suspension articulation.

Specially Designed with Remote-Mounted Coilovers

King's Coilovers are designed for a fairly simple conversion from your standard shock and spring setup and are built to maximize the performance and articulation of your aggressive Super Duty for some serious off-road applications. King's OEM Performance Coilovers are built around a high-quality 2.5" diameter shock body with a honed and cadmium plated cylinder shaft. The coilovers feature a heat-treated 6061 billet aluminum piston and a large-diameter shaft with a tensile strength of over 100,000in/lbs. These come standard with hard-anodized 6063 aluminum remote-mounted reservoirs that greatly improve heat dissipation and cooling for a huge decrease in fade over typical internal reservoir shocks.

Professional Install Recommended: these coil overs will require some cutting of your truck's factory shock bucket for proper installation. Professional installation is recommended.

Returns: King does not accept returns on any of their parts, except in the case of manufacturing defects. Call Stage 3 directly at 623-434-5277 for more information.

If i want to do a reverse level. {picks front up 1" drops back 1"} will these fit?

Asked by: Lane - 1/26/2022

You could do that with these coilovers, though you'd have to play with their height adjustments to get to 1" of front lift.

I’m wanting to level out my 08 F350 king ranch. Are these able to do what I need? Also if they are do I need To replace my factory rear shocks

Asked by: Steven Leonard - 8/2/2021

These coilovers can provide extra front ride height and level your truck's front end, and you would not need to replace the stock rear shocks. That being said, these coilovers are on an extended backorder, and are probably overkill for most basic leveling needs. Your best bet would be to call us directly at 623-434-5277 or email us at [email protected] so we can get more specific about what you're trying to do with your truck.

Can these be ordered with a softer spring rate for a better ride? I have '05 and up axles under my 1996 F350 regular cab. Truck is much lighter then a Super Duty.

Asked by: Paul - 2/27/2020

King can do custom builds (and from what you're doing, you may need more than a spring rate change), but the price and lead time tends to go up by quite a bit. Give us a call directly at 623-434-5277 so we can get more information and see what King can do for you.

Does this include the kit to install the coilover? Is it a bolt on leveling kit?

Asked by: Aldo - 7/17/2018

This is not a bolt-on kit. It requires cutting and drilling your Super Duty's spring bucket for installation. However, King does include instructions, a cutting template, a drilling template, drilling tool, reservoir brackets, and hardware.

does this kit keep the factory ride or does it soften it up a little or harden the ride? just looking to level the truck

Asked by: Lee - 9/1/2017

Coilover conversions almost always stiffen up on-road ride quality by a very noticeable margin. The trade-off is vastly improved off-road performance over stock. If you're solely looking to level your truck while maintaining near-stock ride quality, you'd be better off with a more basic spacer leveling kit or a spring and shock leveling kit.

can these fit on a 4 inch lift?

Asked by: Walt Johnston - 7/9/2017

They will not. Their maximum ride height is 3" over stock, so you'd lose an inch or ride height if you used the King Coilovers in place of a 4" lifted coil spring.
