Timberline Core Ford Econoline 4x4 Van Conversion Kit Gen 4 (1992-current)

Sold out
Weld or Bolt Option

The Timberline Ford E-series core 4x4 conversion kit streamlines the van conversion process by providing most non-standard components required for 4-wheel drive integration. This comprehensive approach saves time and money by addressing both the major components and finer details that distinguish Timberline builds apart from other DIY projects. 

Alongside this kit, you'll need to obtain the front axle, driveshafts, shocks, transfer case, and any necessary transmission or exhaust components. While specific requirements may vary based on year, model, engine, and transmission, our kit significantly reduces guesswork and consistently delivers safe, high-performance conversions.

We built several hundred vans over the last decade while designing and tweaking the kit, all with the DIY builder in mind. We are consistently regarded for our excellent instruction manuals and attentive customer support. We'll be there to assist you throughout your build and address any questions that arise along the way.

Kits come with a 140-page color-bound manual that is thoughtfully constructed and thorough, covering many variations with helpful tips and tricks we've found along the way. 

If you only want the very minimal to get an axle under the front of your van, check out our Mini-Kit, and if you're keen to have us send you a near turn-key kit, checkout our "everything but the axle" kit. We can build you a custom-kit if you need a few things added or deleted and just send you a link to checkout, you'll have to email for that.

Where do I start

We recommend reading up in the Ford FAQ section where you can get up to speed pretty quick, and checking out the Builder Repository section. (These sections may be under construction, just like you, we're always building stuff.)

If you can't find what you need there yet, currently the best way to get the scoop on your van is to message us with your contact and VIN number, a few photos of the van if you have them, and any additional things you'd like to share. (Eg: tire size, gear ratios, van usage, current customizations, long term goals.) 

We are currently available by phone for sales and technical support questions:

Tuesdays/Thursdays: 9am-4pm Mountain Time

Manual Sample

Here are some sample pages from our Ford 4x4 conversion manual. Our manuals include detailed photography, mechanical drawings, torque specs and helpful tips.

It is our goal to make the process as seamless and productive as possible and we've gone to a great deal to design a product that is field-tested and made for a pain-resistant install.  

4-Link & Track Bar design

We chose the 4-link suspension system for several reasons. Having worked on Superduty trucks before vans, we knew they were sturdy but not ideal for everyday driving with varying loads and occasional off-road trips. Many agree that the extra pivot point and adjustable axle placement of a 4-link setup make for a smoother ride compared to standard radius arms.

Setting up the geometry correctly can be challenging. Through years of testing, we've developed a plug-and-play system that consistently works well with our other components. Our parallel 4-link design is simple, durable, and low-maintenance, thanks to high-quality leaf spring bushings, grade 10 hardware, and easy bolt-up installation.

The track bar system is our most rigid and durable design to date. It reinforces the cradle, provides a deflection free pivot link between the axle and the frame, and it's even now available as a bolt-in affair. If you can weld, that kit is a little more affordable to install and can be done in slightly less time. Drilling is minimized as much as we can across all kits.

Coil springs vs. leaf springs

The ongoing debate between leaf springs and coil springs for 4x4 van conversions has clear benefits favoring the more modern coil spring design. Here's why:

  1. Ride Quality: Your van was designed with coil springs by Ford, tailored to its specific needs. Coil springs offer varied spring rates matching different vehicles, ensuring a comfortable ride without guesswork. Additional weight from the conversion sits below the coil springs.

  2. Turning Radius: Coil spring Superduty axles boast a tighter turning radius compared to leaf spring axles, making parking, U-turns, and navigating tight spots on trails easier.

  3. Compatibility: Superduty axles require no extra programming or wiring for E-series vans from 1975 to 2023, seamlessly integrating with traction control and anti-lock brakes systems.

  4. Availability: The 2005+ Superduty axle is widely accessible, with parts readily available and easy to work with. Our 4-link system is compatible with front truck axles from 2005 to 2023, and our track bar system works with axles up to 2016. Kits for 2017+ axles are available upon request.

While we respect other designs, the advantages of coil springs are apparent. Now, leaf springs can make sense in specific scenarios. Very heavy vans and extreme off-road enthusiasts may benefit from their durability and forgiving nature when other suspension components wear out, but with proper components and care, choosing a coil spring rig ensures a satisfying ride without regrets.

Where do I get an axle & T-case

We cover more of this in the FAQ section, but the following is helpful even before you read up there: We've found the site to be the easiest solution to finding an axle across the country.

2005-2010 F-250 & F-350 axles are the easiest to find in many gear ratios, make sure the axle you're buying has the ratio your van currently has or the one you plan to run.

Single rear wheel and dual rear wheel F-250/F-350 axles are identical with the exception of the dually adapter stubs and the front hub thread pitch which doesn't matter. Our kits are also compatible with the Super 60, Fatboy, Widetrack, etc, axles and Cab/Chassis units.

    Tools Required:

    We have a standard list of tools that we recommend listed in the front of our manual and the Builder Repository. It's pretty basic stuff, if you have your own workshop with a lift, you probably have nearly all of them. 

    Tips / Skill Level: 

    Tips / Skill Level:

    1-10 (10 being most difficult) Level 7. There's a great chance if you've made it this far, you more than have the skill-set to complete this conversion. It is involved, but it's very straightforward. If you've done things like lift kits, pulled a transmission, and done a set of ball joints, this will just be another job at the shop. 

    This product may work with other model vehicles.
