Ford E-Series Ride Improvement Package

Get that great ride!

Over several months–and with the help of FOX–we spent many hours testing, measuring, cycling, timing and tuning the suspension to optimize the existing design of these Quigley and QuadVan 4×4 conversions. Our “Ride Improvement Package” AKA “RIP” — custom tuned and valved FOX 2.0 Performance Series IFP Shocks, FOX Performance Series ATS Stabilizer and matched coil springs — once installed, doubles the bump travel, increases the overall travel, increases the spring height and spring rate, eliminates binding of the sway bar, provides rear suspension ride stability and controls body roll and sway.

After hearing repeated complaints from owners about the harsh ride and handling of their Ford E-series Quigley and QuadVan 4×4 conversions, we tested a few of them and confirmed a serious need for improvement. Having more than 20 years of experience in off-road racing and suspension tuning, we immediately knew that major improvements could be made with minimal expense and modification.

Both the Quigley and QuadVan 4×4 conversions are very sound designs with proven functionality and reliability, but drive them over speed bumps, pot holes, or off-road, and you may begin to doubt your purchase decision. Here’s the problem: their front suspension suffers from limited bump travel primarily due to the front frame cross member interfering with the front axle differential housing at full bump. In both designs, cross members are modified to provide maximum clearance, but the unintended result of this modification is an underwhelming 1.5 inches (or less) of bump travel before the front suspension “bottoms out.” Any impact is directly transferred to the van and its unfortunate occupants.

These vans are designed and built for off-road performance and handling, but in reality, these vans spend most of their lives on the pavement…and it is on the pavement where their performance suffers most. Complaints primarily relate to on-road handling concerns of excessive body roll, “swim,” and back-and-forth wallow while simply entering driveways or crossing irregular surfaces.

    I have heard of you guys on Instagram only are you a fairly new company and if so where are you located the money to convert 4×4 Vans has gone through the roof since the successive Quigley and the success of ujointoffroad surpassing them in my book I originally had this quote it out about 10 years ago for 12 Grand but I read in yours you guys start around 18 V and U joint won’t touch anything for less than 20. Completely out of my price range but I am very curious about bumpers and setups I am a welder fabricator myself and have done minor modifications to my van including a rear track bar which improves the handling my book dramatically. I’m now having some leaf spring squeaks so I would like to upgrade to urethane bushings but I just don’t have the driveway or the time to start tearing things apart. I’m very interested in everything you guys have posted so far.

      Hello Randy! We’ve been around since 2016. Our shop is located in Santee, California (just east of San Diego). Unfortunately, we do not offer general maintenance services such as bushing replacement. We’d recommend taking your vehicle to an off-road specific shop as they’d be best equipped to handle a modified vehicle such as yours.

      Glad you’re enjoying our content! Stay tuned for more to come!
