Here's a list of my Clutch services. this is as of 5-14 2008



Stage 2 and 3 non spidermod Clutches. 295.00 Utility Kebc Bearing Removal is recomended.

Price includes 1-4 day turnaround, and 2 Day Return Shipping. I get the Clutch on Monday, You get the clutch back and can ride on the weekend








What is Done is Sheave Clearanced for the Overdrive. Stage 2 is 15% overdrive for lower 650 powered machines. Stage 3 is 20% more overdrive for 700 and UP powered machines.



Stage 2 is 87 Mph gearing. Stage 3 is 93 mph gearing.



Sheave angle is Changed to Ease the initial engagment Claping forces and to Increace Belt Grip by focusing the Belt Grip on the Mid-Upper portion of the belt. NO BELT BURNING OR GRINDING.



Faceplate is Modified, Clearanced, and Lightened to allow full Sheave Travel.

Stage 2 or Stage 3 Spidermod. 295.00 Kebc bearing removal is recomended




Stock Modded Plate



Dalton Modded Plate



Spidermod Clutches are Identified By the recessed Faceplate and the Exposed Fixed Sheave thru the front cover. They are available for Both Stage 2 sheaves and Stage 3 Sheaves.



What is a Spidermod?? What does it do?? What the Spidermod Does is Give the Clutch the ability to run Lighter weights and have them function as heavier weights. The Spidermod changes the Fulcrum point as to where the weight contacts the roller VS Sheave position. Meaning, the Sheave moves Less, moves faster, and gives more belt travel. Spidermod also DECREACES belt-sheave gap to Less than stock Specs.



This gives the Atv more Lowend and is a Dragrace Oriented, Sled Pulling, and Stock Class Gncc Modification. this Clutch is smoother and lighter than the normal Stock Spider clutch machining.



Fuel economy is Increaced by 15-20%







here you can see a Stage 3 VS a Stage 3 Spidermod Clutch Sheave for comparison



---------------------------------------------------------------------------------------------------------------------



LIGHTENED SECONDARY. price is 275.00 1-4 day turnaround and 2 day return shipping.



this Modification removes 9 ounces of unused rotational mass from the secondary clutch. Recomended for Dragracers or Serious Trail Riders. NOT recomended for Ute's running larger than 26 inch tires.









Lighter rotating mass = Less power consumed from the drivetrain.

Teryx Clutch Modification. Price is 350.00 KEBC bearing Removal is Recomended.

The Teryx Modification is different from the V and Ute Modifications as the Teryx Clutches are thicker and vastly different from the ATV clutches we have come to know. The Clutch is modified More than a Stage 3 Clutch. the Teryx needs ALL the overdrive gearing we can throw at it.

They work, 84 MPH gearing, 42-45 low range gearing, Higher top speeds, Far greater low end, and far better belt grip.

This is 100% different approach compared to any bolt on clutch components on the market.


VFORCEJOHN CUSTOM SPRINGS AND ADJUSTABLE WEIGHTS ARE AVAILABLE AS OF 4/20/2010


Comparison Pic of Teryx VS Bruteforce Clutch. They are NOT atv clutches, but very similar.


Dalton Teryx clutch VS Stage III Teryx clutch with dalton cover, weights and spring
Yes, the Dalton components can be enhanced for even better top speed and performance.


Dalton clutch VS Stage III Teryx clutch. Less sheave-belt gap = better initial belt grip, more travel = higher top speeds, more overdrive, lighter clutch assembly, and even more fuel economy.


Teryx Full race clutches loaded with Dalton faceplate, spring, and adjustable weights.

What I do is Clearance the Sheaves, Modify the Sheave angle, Modify the Spider, Modify the faceplate and remove the KEBC.



Modded Stock Teryx Clutch



Teryx Sheave modification



9.4 pounds after the modification. Removes OVER 1 pound

Whether you choose to have the Dalton or Stock cover modified is Strictly up to you.



Both the Stock and Dalton Covers have to be machined for all modifications. There is NO benefit to the modded Dalton cover other than it's Striking Looks and Billet Toughness.

how much to go from a stage 3 to a stage 4? you did the three for me awhile back and now i am thinking of draggin only so i might wanna go with the stage 4. will it make enough difference to justify the $$?

also if i decide to get the 4 i will send you the 2ndry too for lightening

If Obama is the answer,the question was stupid.
