DDP Stage III clutch housing fab

Nice job, you and your family are very talented.

Did Dale say whne the covers are going to be ready, I seen he had them for sale in the kit on his web site.

Hes waiting on that answer from the fabricator. With any luck he should know that answer this week.

VERY nice work Curt ! 8) :wink:

So, I have to ask, what exactly does a stage III clutch do for you? What parts does it replace? Do you keep any existing parts or are they all replaced?

It replaces the primary and secondary clutches with specially machined clutches that are larger in diameter. The larger diameter gives you a lot better low end and midrange. One of the things I have noticed is the takeoff is incredibly smooth, almost like taking off in a car if you ease into it. The kit is made primarily for the RZRs at this point, so I am the geanea pig here as far as figuring out the proper components and settings. I am quite happy with the results so far.

that looks great. xtreme4x4 did a rhino build, the show was on this past weekend. they did a clutch install on the one they are giving away

So this is the torque model upgrade. Sounds like that would be a good clutch for the trail riders, plenty of pulling power when you are not as concerned about the top end speed.

It is a torque upgrade, but you don't lose anything on the top end. Its a good mod for trails, mudding, duning, rock climbing, pretty much anything but top speed runs, and that should still be better than the stock setup. One of the great features is the belt locks up tight. The clutches don't even get that hot because there is so little belt slippage.

Are the new covers going to be plastic, or metal like yours? I'm also wondering if I'm going to have to modify other parts to clear the larger clutch cover.

Don't know if I'm going to do it, but I can dream..

So What is an approximate price tag for a stage III Clutch....I probably really don't want to know, but I am sure it aint cheap.

The first ones are going to be metal, but they are lightweight. Hes trying to get someone to fab reinforced fiberglass housings, but hasn't had much luck with that. The prototypes have been engineered to clear the existing parts on the RZR. The only mod neccesary will be the backer plates inner rib on the clutch housing seal has to be ground off or clutches will grind them off.

They are about 1500 bucks without the housing, about 1700 with, once they are done. Not everyone will want to do it, probably only the big mod guys, for most the standard DDP clutch kit will work well. They are getting very impressive results on the modded RZRs. I have seen a video of a Weber RZR that is able to carry a wheelie now that he has the stage III clutches.

The clutches join two different units (engine/tranny) which can flex, does the metal housing stop that or will it allow the flex or am I way off here ??

The connection between the engine and tranny are solid enough, and the motor mounts on the 09 and newer are good enough that there is very little flex. The plastic housing back is still used, but it does use a metal extension ring as well as the metal housing, so it could stiffen it up. I don't believe flex is an issue at all on the RZRs.

That's awesome Curt! You make it tought of keep up sometimes.

I know this might be a tad early, but has anyone been able to compare this to the new Bikeman set up?

Are you using the same weights/springs as before? Anything gained on the top end at all?

How does your rig now compare and feel to a stock RZR?

The only comparison I have seen are over on RZRForums and most that I have seen favor the DDP setup. I have the only stage III setup on a Ranger at the moment, and we are still tuning on it. Its reacting differently on the much heavier Ranger but we are making progress. Overall I like the performance I'm getting. Its all low end gains, nothing on the top end. I have been working a lot and its interfering with my testing and tuning right now, but I should have it dialed in soon. It has totally different weights than what I had, but they are the same as what DDP is selling to everyone now. The springs and helix are completely different. My Rig is just heavy enough that a stock RZR is slightly quicker, but my new Looney Tunes exhaust may help that 8) I have been running a stock exhaust.

Thanks for the info, I'll check out the RZRforums.

I'm not sure if you thought of this but, if you quit your job, you'd have alot more Ranger time.

I think about it every day 8)

I just re-read you post and noticed to stated that there is still something stock on yours. Are you mad at your Ranger?????

Or does it make you feel like you not THAT out of control with mods? Because if thats it, you honestly might as well put wings on it, there's no holding back now.........
