Maverick X3 Shift-Tek Clutch Weight and Spring Packages

Jan 12 2020


Evolution Powersports Maverick X3 Shift-Tek Clutch Weight and Spring Packages are value priced clutch kits that deliver great performance and belt life.  We accomplished this by creating weight and spring combinations designed to work with the stock secondary clutch components.  Select the clutch kit corresponding to your engine horsepower level from the drop down menu below. See pictures corresponding to the kit part number to see included parts. The B-ADJ-W kit is for the DIY customer who wants full control over their primary clutch.  It includes 6 adjustable weights, spring and screw pack.  This can accommodate a wide range of power levels, but requires some clutching knowledge to achieve desired results.  Instructions are included with each clutch kit to guide the installer to a proper setup for most tire selections and riding styles.  If for some reason the packages listed below do not work for your vehicle or if you plan power upgrades in the future – no problem!  EVP allows you to trade in weights* for heavier or lighter depending upon what your vehicle needs.  This is a no fee service – you only pay for shipping both ways. Our knowledgeable sales staff can help you in dialing vehicle.

Evolution Powersports Maverick X3 Shift-Tek Clutch Weight and Spring Packages consist of technology originally developed for racing where adjustability and versatility play a key role to winning success. Clutching changes are necessary to keep the engine in the proper RPM range for a given tune level, riding conditions and vehicle configuration. Shift-Tek clutch weight kits include our custom geometry weights which improve the overall shift making them quicker to react while getting the power to the ground.

Clutch Weights: The EVP/QSC primary weights have many innovative features which set them apart from the others on the market. Our weights are made from hardened carbon steel which make them much stronger compared to others which can break under hard use.  EVP/QSC weights are different color zinc coated which add another layer of protection while keeping them looking new and to aid in identification during installation.  The primary clutch must remain balanced therefore weights of the same color are installed opposite one another. Since some kits require 3 different mass weights, having them color coded eliminates any confusion.  Our built in, shouldered bushing is a unique feature that only our weights have.  By having the bushing machined and pressed into the arm, it eliminates the need to reinstall the OEM washers on each side of the weight which is frustrating especially if you lose one during installation. The OEM weights have a very shallow or flat arc which contributes to a lazy shift pattern.  Our weights have a more aggressive arc which makes for much quicker upshift and backshift.  Additionally, except for our big turbo applications where additional mass is required, the weights are kept thin without excessive mass on the tip for quicker backshift.

Clutch Springs:  Our proprietary springs are manufactured from the highest quality Chrome Silicon steel, then shot peened and preset to relive stress for a long life. Our different primary springs are matched to the different clutch weights / clutch kits to deliver the desired engagement RPM’s. Included in some of our high horsepower setups is our custom secondary spring which provides additional belt grip.

Shift-Tek clutch kits and components have been race tested during the 2019 BITD and Lucas Off-road series with exceptional results including numerous podiums and championships. The better line of Shift-Tek clutch kits and Badass WBB belts provide unmatched performance, adjustability and belt life for any vehicle setup from mild to wild.
