I'm looking at replacing my DM flywheel setup. I'm tired of the chatter and the feeling that something is out of balance at times. My question is which clutch is better in terms of longevity. I don't drive the truck much, I don't plan on any motor mods and I don't pull any loads with it. If anyone has any suggestions it would be much appreciated. I only want to do this job once.

 

A lot of guys are happy with the luk. I have a south Bend and am happy but I've got a few more ponies than stock. Personally on a stock motor or slightly modded I would have gone with the luk

 

Thanks Moose, I appreciate it. Does your engine run smoother with the single mass flywheel ? Mine feels like something is out of balance sometimes.

 

I never had a dmf. I went from the luk smf to the south Bend smf

 

You probably broke an internal spring in the DMF... which is causing the vibration, and in the #1 failure we see in the DMF clutches.

I have almost 80k miles on a HD LUK SMF setup... I would have never thought it would have lasted this long considering what the truck is used for and the power output. South Bend is also a great clutch. if you want a stock feel and are going to be running under 300-325hp, the HD LUK is cheap and reliable and feels great. SB are a bit more stiff and grabby considering the masterial they are manufactured with. I think SB has a organic single disk 400hp clutch that I am planning on getting next as long as its compatible with the LUK SMF flywheel.

 

Where can I get the HD LUK clutch at ?

 

Google online and find a distributor. A lot of parts houses have them online. I'm sure summit does.

I order locally.

 

Take the inspection cover off at the bottom of the flywheel 4 bolts to remove and very easy to access. You could find some of those missing damaged parts laying in the bottom of the cover, I did.

 

Sounds good I'll look at that. I appreciate it.

 

When I bought my truck the DMF was on its very last legs. I went with a Luk SMF and matching clutch from rockauto . com. The difference with the new clutch and flywheel is amazing. No more hard starts, rattles, or clatter when you shut it off. Runs much smoother

 

Don't buy more clutch than your engine needs. If your engine is stock or reasonably close to stock power output, then use a stock clutch.


The reason being is that high-output clutches are designed to transition at a higher power range. For example, say that a 600 hp clutch is designed to slip at 400 hp with partial pedal. Or a 400 hp clutch which is designed to slip at 300 hp with partial pedal. If you put the 600 hp clutch on a 400 hp engine, then what you end up with is no "friction zone" in your pedal. Your clutch will be full on or full off.

 

I went with a LUK and the feel is amazing compared to the original pedal resistance; very easy clutch engagement and disengagement. I've never had a SB but I'd highly endorse a LUK...

 

I think I'm going with the HD Luk. I'm tired of the chatter and the out of balance feeling sometimes.

 

Rockauto is the cheapest place I've found the Luk kit with the solid flywheel. I have order a few from them and put in guys trucks in my shop. I think even with shipping, Rockauto was about $100 cheaper than Napa.
