SMB Tired Coil Springs

Greetings All -- so my 2002 SMB Quigley E350 EB seems a bit tired in the front. Recent threads talked about CC880 or CC 880S solving a good part of soft/tired front ends. My front end is roughly 3780 lbs. without me, passenger, etc. Rear weight is 6080 lbs.

I spoke with MOOG - and their "fitment" for recommended springs for a 2002 E350 van are - CC81370 Variable and CC 81368 HD Variable springs.

Can someone explain how they came up with the 880's vs the 81368's or 81870's as correct fitment - going against MOOG's recommended springs ? Just asking - respectfully --

Thanks !

So I've been over this with a few people and this is my own personal opinion. Moog makes "replacement parts" that are designed to "replace OEM parts."

Moog 880/880s are not "replacement parts" because they raise the vans. Do they fit, yes but they are not direct fit replacement OEM parts.

Because of this I don't think MOOG will ever recommend those springs for our applications. Additionally you'll never see them on the moog website for your van either.

To my knowledge the above is absolutely correct.

There was a great guy named Ramsey who did 4wd conversions and was on this site for a long time. He pioneered the RIP kit to improve Quigleys and also started Agile Offroad, both of which you'll hear about if you're on here much. As far as I know Ramsey started the Moog 880 upgrade and I can attest that it does improve these vans dramatically.

Who knows if he was the first.

RIP Ramsey, you are missed.

The 880S is what most of us with built out E350’s replace with, it’s a bit heavier duty than the 880 and may raise your front end an 1” or so. That being said, you may have to address a saggy rear end in the process.
