Merci très bon service

Terrible, 192km and the slider blocks failed leaving me helpless on the trail. I've used trailbloc on previous machines that were okay.. the power bloc might be good for sleds but not polaris rzr's. Spent hours tuning to umatek's recommendations for my machine and break in procedure and it failed with less that 200km. Spend you money elsewhere. Out almost $1000.00 for this primary and cost me $2500 to replace with secondary and belt. They do NOT hold up to their warranty.

Fast shipping and much better than the stock unit that started to disintegrate after 700km only.

Trying to give a good test run but waiting for more snow

I don't typically write reviews, but i'm very satisfied with the purchase of this primary clutch. My Sabercat wasn't pulling as it should, revs were maxing out about 7000, the clutch rattled and parts were expensive and hard to service. Buy once/Cry once with a new primary was one of the better decision's i've made. This installed in minutes, came very close on tuning out of the box (removed one disk to get just a touch more rpm) it engages extremely smooth, is quiet, and the sled rips now. Tuning was dead simple without having to remove the clutch. Will recommend a powerbloc whenever friends have primary clutch issues.

Not a lot of miles on it yet but does it ever make the bike drive better then the stock clutch. Very smooth

This upgrade has been absolutely amazing, simple bolt on, factory set, engagement is at 3600rpm. Super lightweight, very responsive and most of all it's quiet.

I need to do some more testing, but it seems to be working good right out of the box.

Great item, as described...and shipping was fast.

Parfait

Everything good.

Absolutely the best clutch out there put one on my 800r renegade and it’s absolutely amazing!!!! Can’t go wrong

Fit perfect on my 2010 Crossfire 800 HO, calibration is spot on. Feels like it has more power and better throttle response, definitely less vibration then OEM.

Fast delivery. Cheaper than stock replacement and noticeably lighter.

My stock primary wasn't worth rebuilding. This was suggested by my motor builder and it was the same price as used primaries. Fast shipping and literally bolt on out of the box, torque, and ride. Not gonna lie is was skeptical at first. It's doesn't have ½ the parts etc. But it's definitely better performance than stock. I'd recommend cvtech all day long

The original clutch on my 2014 SR Viper RTX was very noisy and sluggish. When the new CVtech Powerblock 80 was installed, it was totally quiet and the performance was a lot better. I am very happy and would highly recommend this clutch.
