ive got a 00 scr4004x4 and put a hpd aggresive clutch kit in it .love it!! ive been reading alot about the new rollers. how do they compare to what i have and can i put one in with my aggresive kit or are they made for stock applications??[weights-helix-springs]??

 

Weltmaster, I cant comment on how well they work, because I havent installed mine yet. I am waiting for some warm dry days so that I can do some testing along the way as I put this stuff on. I am first going to install the roller and test then add the agressive kit. When I ordered my HPD roller and aggressive clutch kit he, (mike) made no warning that the roller is just for just stock clutches. Also the Helix in the roller has the same angles that come with the helix on the agressive kit. Mine are 40 - 36.

I had doughts of big performace changes in the way power is put to the ground with just a roller clutch from the info I read here so I went with both the roller and the Agressive clutch kit. I realy like concept of rollers verses the buttons in the shift drum and the HPD roller is built very nicely I thought.

You seeem to really like your agressive kit...what were the pro's and cons you felt with yours and is it still able to crawl along in the slow stuff as well as the stock clutch setup, now that you have a higher engagement? (not that the stock set up is real good at it) Ever do any riding at Wayne Forest?? thanks, gj

I have the HPD roller clutch. I can't say I noticed to much of a difference from the HPD clutch kit that I installed with the pipe. I put the roller clutch in when I had a couple of sets of buttons explode on me (yep - shatter all over the place), so it was more of a reliabilty thing.

I do like how easy it is the change the settings, and it comes with a chart that shows what the poundage of each setting equals. I can adjust it for each ride which I like - ie. quicker back shift for trail riding and TT's, slower for speedway and high speed trails.

The HPD unit is very nicely made, and worth the money just to look at the engineering of it!

 

I have the Aaen Roller. I added it after having the HPD trail pipe and agressive clutch kit for about a month. I for one noticed a nice difference. No more lag when hitting the throttle at 20 mph. Acceleration seems to have improved also. The power just seems to kick right in now. Wheelies are easier without the initial lag.
