Packaged in kits of 17 springs, all spring ends are close-wound to prevent arch deflection and then match ground to a uniform length to ensure equal load distribution among all the springs in the clutch assembly. These springs are made from high tensile spring wire to slow loss from fatigue. Engineered by Sonnax specifically to meet the requirements of transbrake drag racers, these springs offer improvement over the OE and any commercially available springs.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"text-align: left;\"\u003eConsistent and reliable transbrake release rate\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eLonger life through better materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":48088238653662,"sku":"S103976K + S103966D","price":139.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/S103976AK-S103966D_PATC_111.jpg?v=1776105975","url":"https:\/\/transmissioncenter.net\/products\/powerglide-performance-hp-billet-piston-and-spring-kit-reverse-clutch-1962-73-sonnax-28761-01k","provider":"Transmission Center","version":"1.0","type":"link"}
