I noticed when looking at aftermarket clutches, on the Valair single discs for the NV5600, it says 13"x1.375" also available with 1.25" hub just specify if you need this. What's the difference and how do you know if you need a 1.25" hub?

 

Nobody knows?

 

Not real sure my friend, I would contact Valair and they can tell you.

 

More than likely if the truck is a NV5600 after 2000.5 It will have a 1.375 input. The early nv5600 from 99-00.5 had a 1.25 input. Being your truck is a 2002 it got a 1.375 input shaft in it

 

Thank you sir. What are your thoughts on Valair clutches?

 

So does that mean mine has a 1.25 input being a 01 with a build date of 6-00?

 

i have ran valair in a couple trucks of mine all dodges and i ran the single and the dual discs i liked them both good clutches and a decent price i have one in the ranch truck with 300k + and its still going strong
