We offer a full length Add-a Leaf that goes directly under the top main leaf and is wrapped under both spring eyes to fully support the main spring. It has the same profile as the stock leafs and will add 1 to 1.25 inches of lift. We also have additional factory leafs that can be added for additional lift or side to side corrections. National Spring also makes custom spring packs for us.
I am so confident that our custom valved FOX shocks will solve your handling problem, that I will remove them and return your van back to where you started, for free, if you are not happy with the results.
The FOX shocks are so superior the the other off the shelf brands people are using - there is no comparing, and only $130.
