JConcepts Black Jackets & Stackers truck pre mounts

JConcepts have extended their pre-mounted truck line to include Black Jackets & Stackers. The Black Jackets, constructed from very small square pins, provide additional grip on loose conditions with a light amount of dust and debris across the surface. The tread spacing near the outside rows are slightly open allowing maximum flexibility to adhere to smooth and slick surfaces providing a reasonable flex contact patch. The Stackers reveal a heavy center lug design which are supported at the lower base with extra rib features and tiny fillets which provide a heavy forward gripping force. Directional slashes cut into the tread soften the lugs to absorb bumps and also increase the lug flexibility to accommodate loose conditions. Both are available in green compound on white or yellow Elevated wheels.
