Re: Newb with an 93 E-350 Quigely
I have never had the same bumpstop issues as you and others have posted, pre/post Deaver/bilstein, so not sure exactly what the remedy would be. But, do a search on here for Deaver springs, I had them make me a set of leafs for the rear, gets rid of that lift block and makes a proper weighted spring, they also make front coils. huge improvement over stock, it may also be that your bilsteins need replacing, stick with them, they are the best as they are valved properly for our heavy rigs. I believe we would have the same setup. In the 5000 series, you would use a Ford f-150 rear shock for our front, and a yellow bodied motorhome shock for our rear. I might be able to dig up the part numbers if you need them. Also, I have the upgraded HD 4600# coil up front, it may be that it was an option from Ford/quigley, or comes standard in the diesels, but they are a ford stock part, should be a red tag on the coil itself ID'ing it.
