Timberline can convert your 2 wheel drive van to 4x4

We are currently offering outside conversions on Ford Econoline vans with very few limitations. We have also added the CHEVROLET EXPRESS / SAVANA to our conversion line. 

Here is a snapshot of the conversion process


10-20 minutes by phone, email, or in-person, maybe some photos, a schedule, and we'll help you make good decisions


Bring it to us, have us ship it in. 5 minutes of paperwork, bring us a deposit check or use a card


We'll do the heavy lifting, just give us a few weeks


Fly in, drive in, ride in, or have us ship-out. 10 minute demo, bring a check, adventure awaits


Most common answers:


-Ford Econoline 1994-2018 only

-$15,700 +upgrades/mods+wheels and tires, Q4 price increase of $700 reflects new standard of replacing hub assemblies and u-joints on all front axles, not always required, but we recommend it as part of our ongoing effort to improve longevity. 

-Approx 2 week turn around

-Timing schedule varies, call or email for current estimate.

-No rusty vans, nothing more than 23 feet long, must have 8 lug axles (all 250/350/450 + 08+150)

-Upfitting and reconditioning available, no cabinets or bed platforms currently



This is where we listen to what you're trying to accomplish, how much you know, guide you with our experience and help in any way we can. If there's an opportunity for us to convert your van or help you decide whether a prospective vehicle is a good purchase, we'll gladly do so. We'll give you cut and dry answers. We won't lean on you, and we'll give you the tools you need to make informed decisions. (Only about vans.. honestly, it's really the only thing in life we've figured out.)

Additional upfit:

We do have capacity to do a fair amount of upfitting. We're not a full camper shop, but if you want your cargo van paneled, a window cut in, exhaust fan, additional seating, hitch, racks, or work vehicle equipment, we can handle that. For a more comprehensive list of additional upfit options, view here. 


When your date comes up, you can drop your vehicle off at our location in Golden, Colorado. If you are in metro Denver, we offer free pickup of your van. If you are out of state, you can arrange to drive it in and we can drop you off at the airport. You can also have your van shipped to our location which we can assist with.


We have a simple 3-page reader that will be provided to you after the consult which just needs a signature, and we require down payment. The terms are $9000 down payable by cash, check, or debit card. If you'd like to use a credit card, we charge 2.5% for anything over $5000, 3% for AMEX. If your project requires significant upfit, we may opt for a larger down payment. 

build (Ford)

We need your van for a few weeks. In a real pinch, we can do a move faster, but we typically need a day at alignment and a day at exhaust for gas vans which does eat up some time. If you can't wait the 6-8 weeks to get your van in, let us know and we'll see what we can do.

Your van is fully insured during its' stay at our shop. We are in a small commercial area surrounded by residential homes in an older neighborhood. Our shop is tucked away and very safe.

What we work on

Fitment: 8 Lug E-150 (2008-2014), E-250 (1995-2014), E-350/450 (1995-Current) All standard engines and sub-models. We are currently limited to vehicles less than 23 feet long and less than 11,000lbs empty. For reference, most conventional Econoline vans weigh in between 6,000 and 7,000lbs. 

Van Condition: We generally prefer to work on nice non-rusty vans. It doesn't make sense to spend a lot of money on a dilapidated vehicle. We realize all vans are used and have personality. We will consider converting anything that fits the above described so call or email with questions.

We accept all major credit cards, however, there is a 2% charge for anything more than $4,000. Colorado residents must pay tax on applicable parts.


When your van is finished, you can schedule a pickup which only takes about 20 minutes. If you are out of state and want your van delivered we can help with that. We also offer free airport pickup if you'd like to fly in and drive your van home. If you need some time to get here, we can store the van for you for up to 30 days. Additional storage of vehicle may incur fees as we are limited on space.

You will receive a build sheet with the details of your conversion components for future service and we will spend whatever time you need to explain your new setup. We generally take folks on a quick 5-10 minute test drive to go over the 4x4. Balance due by cash, certified funds or debit card for balance. Credit card payment fee schedule same as at drop-off.

Colorado Residents:

Timberline will collect applicable sales tax on parts used in the conversion process. A good deal of the components used already have taxes paid on materials. 

We offer a free 1000 mile checkup on your van, just to bring it in and shake it down, check for any details needing attention. If you are in metro Denver, we offer free pickup and delivery service of your van.
