Yes the big venom kit and it does have glide washers. I'll be running TD max pump on asphalt Friday right now it's stock running 10.3s we will see what max pump does.
Are you talking about the big venom kits for sidewinders. I believe these come with glide washers I think.
This is the kit top on my list so far.

A little bird told me that Thunderproducts has a new secondary spring in the works that is proven on asphalt to make more speed and eliminate coil bind!

Well,i think all 18,s will have same clutches,as 17,s and maybe a primary spring and secondary roller change,and that will be about it,IMO of course. But since we are still throwing bones around about best clutch set ups,my 17 stage 4 tune w/3" hole and CAI runs good with stock belt,Supertip weights,i think the helix is Supreemtools that Allen has in his kit,and secondary torsion spring,may be some sort of cat spring,since the tang is offset 90 degrees from yamahas,so twist is 10-30 degrees,and at 30 degrees where we now have it,it is very hard to twist and load onto the helix,my guess is if it was a normal yammie spring,it would be 100-120 degrees twist,i may be wrong,but will try and find out some more info this fall. this set up with heavy ramps,and straight 38 degree helix,with his special primary spring,runs 3000 engagement and shifts to 9000 and in hard conditions may run to 9200 but sweet spot is 9250,and we have 710 miles on in all types of snow,and so far belt shows very good wear.
