Clutch Help, Which one???

[RGH43]

What is the problem with using a stock clutch to replace a stock clutch? I have to put in a new clutch since I burnt the stock clutch backing up the fiver repeatedly & riding the clutch, it is now starting to slip. Long story, other wise I am sure I would not be asking this question. Reading about the SB clutches and with the rattle & noise problems, the backing a trailer issue. Since I don't have a 4X4 to help, I am concerned about this. I don't do anything like pull a sled, drag or off road, I only use it to pull a 16K Fifth Wheel. I may increase the HP some in the future say 50 to 100Hp if needed so far I haven’t seen the need. In this case is the stock clutch OK or should I get one of the SB clutches?



Does the SB clutch require a great deal of effort to disengage? Is there a slave cylinder or anything I should get to assist in helping when pushing the pedal in? What is the hydraulic upgrade and do I need that too? Is the stock flywheel OK to use if it is resurfaced if needed?



If it turns out the SB clutch is the best way to go which one should I get for my type of use?

I am running a SB OFE with the upgraded SB hydraulics. Rip just installed it for me last week.



So far I like the setup, yes it is a bit grabby but I think some of that will go away as it breaks in. It also is a little noisy in neutral or when under 1,500RPM.



The stock clutches will do what you want, but I do think the SB is better built and will probably last longer. SB does make a clutch that is close to stock in how it works, I think it's the Con O.



Sorry, I probably didn't help much.

rgh43,



You asked, in my opinion, a wise and thoughtful question. Why, indeed, must we pay big bucks to modify our trucks with expensive aftermarket products which often will introduce a new set of problems?



SBC is a fine company and IMO they produce some outstanding products. You might want one of their clutches if you are using your Dodge Ram to pull 30,000# trailers, sled pull, drag race, or possibly plow snow full time.



For the average owner who uses his Ram for a purpose within reason of the designed operating parameters established by the manufacturer, you do not need an aftermarket clutch. And if you install one you may, in fact, regret the decision.



Aftermarket clutches have to be built with higher coefficient of friction materials, stronger springs, and other materials that will require more pedal effort to depress, may grab abruptly on engagement, and may not be as comfortable and satisfying to drive as your factory clutch.



I slightly warped or glazed the pressure plate and/or flywheel on my '01 Ram w/HO six speed backing a trailer then shutting it off too quickly, before the clutch had time to cool. After that it chattered a little on engagement.



I consulted all the clutch experts and ultimately decided what I needed was exactly what Dodge had provided OEM. I bought a new LUK clutch from an internet discounter and had it installed by a skilled mechanic. He polished the flywheel to remove the glaze and reinstalled it. I never had another problem with the clutch, even pulling heavy trailers commercially,



Your truck, your money, your choice. My advice is to replace it with an OEM LUK. I don't think you'll be sorry.



I give Dodge and Cummins credit for knowing a lot when they built our trucks and engines. I don't automatically assume something from the aftermarket would be better.

I agree with Harvey on this one, if you stay stock then go with stock. If you do have plans on power upgrades then I would definitely go with a stronger clutch now rather than later.

I do appreciate the feedback. Has anyone heard about a Valair clutch and their reliability, how long do they last and how do they compare to the stock or SB clutch.

SHobbs how is the Con FE as far a noise (rattle) and jerking in reverse as I see you are backing a big Cardinal. Nice rig.

My 5er is 39ft long and tips the scale right around 13k not sure of the tongue weight. I have not noticed any noise at all with the clutch at idle or while driving. Towing the 5er is much better with the OFE compared to stock, 1st gear launches are way better and much smoother. As far as backing I try to let out on the clutch and let the idle of the engine move me.

I have moved a couple of 5er's here in the park where I am set up and this has worked the best. With that said I can get some serious jerking if I try to go back and forth on the clutch pedal.



Strength and durability of SBC have been well documented here. There are members that have punished these clutches and they keep holding. As far as compared to the stocker I believe the SBC will out last it by a longshot. I expect to get alot of life out of mine being that I float the transmission and use it for launches only.

I just put a Valair in my 97 and love it, my brother had a SB clutch put in and it is just too much for me. Call Valair and talk to Dan, he was very helpful with clutch selections.

What do you mean by just letting the idle work for you? I must be missing out on a trick or something.

 

[SHobbs]

I tried several things after the OFE was installed as far as backing. The best I have found is just to let the clutch out and let the truck creep if I need a little more power I add it. Not all situations are perfect but if I can do it this way it is easier than being off and on the clutch.
