I was looking on HTT's site for comperssor upgrades and saw that stock is 56mm unless your truck is a one ton. I have a w350 and was wondering what the stock wheel measures on my truck? Thanks.

 

I think that's only on HX35's and WH1C's. My stock H1C had a 54mm wheel, I'd assume yours is the same.

 

Thanks gman I was a little confused about that one.

 

It's very confusing. Getting accurate info for a holset is...well, not easy. The important thing to remember about any of the HTT housings is that they have MAP slots, whereas your stocker doesn't. They (the MAP slots) keep the turbo from surging (which is easy to do with a 5 speed) and also provide lots of cool whistle.

 

My old compressor wheel measures 54mm at the little end.
