Track Bar Bracket System for E-Series 4x4 Conversion and Superduty Axle

Sold out

The Timberline Track Bar Kit is designed to work in conjunction with our 4-Link Kit to provide stability between the Dana 60 axle and factory van frame. Our design bolts directly to the outside of the power steering gearbox frame area and only fits one way. We have done extensive work to make this the most rigid track bar system available for 4x4 solid axle vans. 

Installation requires trimming of the engine cradle which is easily accessible. Our design safely relocates the support area of removed material from the cradle crucial to proper fitment, rigidity, and longevity of the van chassis under duress. The forces imposed on the frame-side track bar bracket during wheeling are significant, and we've seen other manufacturers' units flex, crack, and break. 

Currently, our design is a weld-in effort. It's a pretty simple modification for this to be a bolt-in design, and we'll soon offer a "no-weld" version of our popular track bar kit.  

The Death Wobble!

One of the more frequent questions we get is about the death wobble. Many of us have been in a short wheelbase Jeep with big tires and 150k mile tie rods, and you hit a bump on the freeway and are suddenly launched into a teeth-chattering frenzy while you try to slow the vehicle down to a crawl without stopping traffic.'s the worst. 

We've heard this complaint about a popular brand of 4x4 vans, and we've worked a lot to mitigate this issue with our vans. We see a lot of big dual stabilizer kits on vans with 33" tires and all that's doing is soaking up the fallout from whatever other problem there is. With proper geometry and design, a van should be able to run a very inexpensive and small stabilizer with no issue. Our design calls for a $25 Monroe stabilizer that was designed for the van itself, and it works great. 

The (3) main factors that go into death wobble in a coil spring van:  joint condition/quality, track bar rigidity, and a proper sway bar setup. If you have those 3 components sorted, there just won't be any death wobble. 

1) Replace everything when you build your axle, all your tie rods, ball joints, bushings, everything should be kept up on properly, and setting a good base when you build your van will pay off for years. 

2) Trackbar - our setup is extremely rigid and the only one of its kind employing a solid steel 1.5" tooled bar with heavy-duty adjustable Heim joints ensuring no pre-load tension on your track bar system during install. 

3) Sway bar - get yourself a heavy-duty sway bar. We like the Hellwig 7718, there are other options. If you're going wheeling or going to be out in the trails for a few days, try some JKS quick disconnects and your flex and ride will soften right up for the trail. Those windy days in your high-profile van out on the flats, you will be so happy you're running a stiff sway bar. 

Fitment Designed For:

1992-2021 Ford E-150/E-250/E-350/E-450, Cab and chassis/cutaway variants included

Alternative pitman arm for Gen 3 vans found here. 

Truck Side: Fits 2005-2012 Ford F-250/F-350 SRW or DRW axles, 2013-2016 Ford F-250/F-350 axles (For largest brakes)

Tools Required:

Standard hand tools, ball joint press or similar to remove axle-side original track bar ball joint, pneumatic tools recommended, torque wrench, threadlocker, 220V welder with shielding gas. (Stay tuned for bolt-in kit)

Included: Tooled solid steel track bar, heat-treated 7/8 shank Chromoly heim joints, various misalignment spacers for optimal bar clearance, grade 10 3/4" hardware, axle and frame side brackets, ball joint cup-cap, appropriate hardware.

Construction Notes: 

Plates made from CNC cut 1/4" and 3/16" A36 steel, track bar tube 1.5" cold-rolled solid steel round, C1018 grade. Heim joints are heat-treated Chromoly with zinc misalignment spacers. Frame side track bar bracket comes powder-coated with weld pattern pre-cleaned. During installation, axle-side track bar bracket becomes thoroughly hot so this item ships bare. After welding up, allow to cool slightly and prime/paint, effectively bake-setting your paint.

Tips / Skill Level: 

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

This design requires cutting and welding. It can be done with an angle grinder without much brain damage, a good plasma cutter will make super quick work of the job. Instructions are included for cut and again, it only goes together one way.
