i have a 98.5 cummins and im replacing the clutch i was just wondering what every ones opinions are . i have a daul disk but its junk. any input will help. this truck has a quadzilla chip. thanks

 

I like south bend clutch or haisley machine's clutches, I'm running a South Bend 3600# now, works great

 

spec makes some really great clutches

 

Valair DD

I have a southbend dual disk and I love it no problems what so ever. Maybe a little chatter sitting at idle but otherwise awesome clutch

 

southbend and valair are both good clutches.

 

you may be able to get your DD rebuilt with new facings for about 1/2 the cost of a new one.

I am a Master Distributor for Valair so I normally recommend them, but southbend has a good DD clutch if you decide to keep your stock 1.25 input shaft(not recommended for over 500HP).
