Mini Kit - 4x4 Conversion Kit Ford E-Series Gen 3 + 4 (1975-2022)

Sold out
Year of Van

Just the basics; this is the foundation of our front-end kit that will get you on the path to your 4x4 van conversion. Whether you're a seasoned builder who doesn't want to invent new technology or you're on a budget and just want to get the front end under your van, this is the most affordable way to execute.

Timberline 4-Link front end kit

The easiest and cleanest way to pair an F-Series Superduty axle years 2005-2016 to your Ford Econoline van. This bolt-up solution works on Ford E-series vans over a large swath of years and options, covering both Generation 3 and 4 vans, years 1975-2021. 

Trackbar kit

Our track bar design currently requires welding in the brackets. The path to do so is made very easy both by design and the instructions provided. The Timberline track bar is designed for maximum differential clearance, extreme rigidity and features serviceable leaf spring bushings for extreme durability and years of hassle-free use. 


Our updated standard arm configuration works in conjunction with our track bar setup and perch, allowing you to bolt up any 05-16 250/350 Superduty axle with your original van coil springs and achieve 5" of overall lift, good for 34 inch tires, and up to 35 inch with some light trimming (wheel-offset-dependent.) 

Sway bar link tabs complete the Mini-Kit and a 45 page full color bound manual that goes through the teardown process and installation, significantly shortening your learning curve on more than just the parts we're including. 


Why the 4 link? After working on Superduty trucks for years prior to working on vans, it was no secret to us that they were stiff, unforgiving, and purpose-built for work only. That's all fine unless you're trying to drive the vehicle daily with a variety of payloads, uses, and periodic ventures into the dirt. It is a popular opinion that having the additional point of pivot and the ability to dial in the placement of the axle and geometry of the suspension lends 4 links to just ride and drive better than a standard radius arm. 

The difficulty lies in dialing in that geometry, which we've done over years of testing. Our standard system is plug-and-play and works every time with the rest of the parts we've compiled. The parallel 4 link design is simple and extremely durable, rarely requiring service. Utilizing extremely durable leaf spring bushings, all grade 10 hardware, and ease of bolt-up design are all important features. 

Coil springs vs leaf springs

There's the big question, isn't it? We've met many people who were very happy with their leaf spring vans and we've had people ask us to build leaf spring kits, so there's got to be something good about them, but we chose to lean into the coil spring design.  Our opinion on this isn't gospel, it's just an opinion, so here's why we do what we do:

1) Availability- the 2005-2016 Superduty axle is one of the most widely available axles in the country. Ford built scores of these trucks over a long period, and they're everywhere. You won't find Ford telling you parts are obsolete, every corner parts store carries parts for them, and they are very easy to work on. 

2) Ride quality - Coil springs, your van came with them, that's how Ford designed it, and they've already picked out a coil spring rate for you in the front of your van that matches the basic weight and usage of your van. Can this be done with leaf springs? possibly, but we haven't driven one that felt right. This becomes a particular issue on lighter-weight vans. A dead empty gas 4x4 E-series cargo can weigh as little as 6,000lbs, and a fully built diesel high top can often weigh closer to 10,000lbs loaded. Bolting up a Superduty axle in place of your existing front end only adds about 200lbs per front corner, basically like adding an extra passenger, so keep your springs, and keep your ride quality. 

3) Turning radius - Is this a big deal? Probably not for everyone. In the shortest answer, we've driven (and built) leaf spring vans and coil spring vans and there is a noticeable difference in the last bit of the steering that feels like the later model axle has the capacity to allow the vehicle to turn tighter. Ford vans have a 135" wheelbase which is not super long, so either choice is fine, but you can roll up to a standard American intersection and make a u-turn easily across 2 lanes and that's what makes our design feel like it works. 

4) Compatibility - It takes exactly 3 different abs sensors to cover the entire program of E-series vans that all interface equally with the 05-16 Superduty axles. There is no additional programming required, RSC, ESP, TCS, 2WH ABS, 4WH ABS, whatever flavor you have, there will be no complications in the operation of your system. It just works. You won't need a drop pitman arm, we have steering solutions up to 8" of lift that require no drop-pitman arm so even in RSC vans, it just works. 

Where do I get an axle?

We've found the site to be the easiest solution to finding an axle across the country. You can use anything 2005-2012 F-250/F-350 either single-rear-wheel or dually design, and they're both the same. (Front dually axles have wheel hub spacers and the hub-studs have a different pitch, but they are otherwise identical)

For upgraded brakes, different gear ratio options, and a factory rear locker available, look at 2013-2016 axles. Yes, we'll be running down the 17+ axles soon here for testing and will report with results. 

If you don't want to deal with your axle, we can build you one, we can also ship you a core if you'd like to build it yourself. Axle cores start at $500 and typically built axle runs about $5k completely gone through. As a sample: replacing everything on the axle new except rebuilding the guts (which very rarely needs to be done), should cost about $2500 in parts if done properly with good quality steering components (eg Moog), Motorcraft ball joints, and Timken or similar hub assemblies which are expensive, yes, including all-new braking components. If you're budget conscious this can be done for less.

Tips / Skill Level: 

1-10 (10 being most difficult) Level 3-4

A Ford truck axle is fairly heavy. Installation can be done on the floor in a garage, with jack stands, a pry bar, ratchet straps, and a good floor jack. Installation is most easily completed on an automotive lift with an axle stand, however, it is not necessary. Please exercise patience when working with heavy equipment and parts and always have a buddy to help. This install will be easier to do with 2 people.
