SHIFT-TEK DIFFERENCE
Clutch Weights: The EVP 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 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.
