What to Expect from a Gen 2 Duraclutch
In low range, engagement was almost immediate and slow speed performance is nothing short of amazing. I was able to climb up pond dams and embankments with ease. Engine braking in low is also amazing. Keep in mind this not your car or truck, there is no hydraulic system in the transmission or clutch so there are going to be jerks and qwerks as this is essentially a direct drive therefore it will buck and kick as does the stock clutch but my point don't expect it drive like your car.
Testing done on a 2016 XP 1000 Two Seater I was able to drive 40 mph in low easily and hit a speed limiter at 45 mph in low with it. So for the guy who drives slow I would highly suggest he use low more times than not. Four seater models, the High Lifter and Rock crawling editions low speed limit will be different due to low range gearing.
There is a slight howl or harmonic noise as the clutch initially engages and driving slowly and I suspect that is from the belt having to wrap so tightly around the primary clutch in low ratio. As soon as you pick up rpm and any speed at all it goes away. I hear something similar in the stock clutch and it goes away, so this is normal.
All operation in low is very smooth to me.
Operation in High Range:
The belt noise or harmonic noise is louder and lasts longer, to about 10 mph. If you stomp the gas from a dead still or almost dead still there is an instant rpm response then a shift feel around 10 mph then it is smooth on up. This comes from the new lower starting ratio and it staying in that lower ratio until you build enough rpm to have the clutch shift out of it. This is normal and barely felt at all in low and truth is, you should not be flooring it from a dead stop anyway, you should not be buying a Duraclutch for drag racing.
In high range engine braking is good and smooth until you get to 10 mph then it is pretty aggressive as the roller goes into the EBS notch on the helix in secondary clutch. Any movements or driving under 20 is a bit qwerky in high range but I totally expect that. Once again this is a activity you should not be doing, under 20 stop put in low.
My overall impression is it is a very good combination of a low range slow movers clutch with the ability to go fast. I did notice shift phase rpm is a good bit lower than the stock RPM and it was around 7500-7600 and at top speed of 80mph at speed limiter it was around 8300.
Makes more sense to me to have shift phase RPM lower than stock as this is more geared for slower movers or people with higher loads so the clutch calibration will do that well with less belt slippage in high load situations as well as not having to listen to such high rpm when you are in low range. Again this RPM is normal.
Any negatives I had while driving my RZR with the Duraclutch was only when I was doing something I should not be doing, which was trying to drive under 20 mph in high range.
So once everyone is educated on how the clutch works, gets used to the different sounds and operation right off idle then they will love it. In clutching there is no such thing as one set up doing everything well, it just won't. I tell people on a daily basis you can't rock crawl on Saturday with one clutch set up and go dune the next day with same set up, simply does not work.
Have any questions, holler!!
