Quigley's Ford van 4x4 conversions are renowned for their durability and versatility, and Shockwarehouse often gets requests from customers with Quigley conversions on their Ford E-350 vans. On most vehicles, shocks should be inspected and possibly replaced at 50,000 miles. On a modified offroad van the shock life of a shock can be much shorter. Whether you're looking to replace your Quigley E-350's shocks with soft, comfortable factory shocks or high performance shocks, we have you covered.
Quigley has been converting Ford vans and trucks to 4WD for almost half a century, and there are more than 15,000 converted vans out there, and many "Quigley" vans have been modified after they left the Quigley factory or were built by third party installers, so fitment is not guaranteed and this guide should not be considered definitive. You will need to measure your shocks in order to ensure proper fitment You can find our guide on how to measure shocks here.
