This ZF 1358 304 256 mainshaft is specially designed for ZF 12-speed AMT transmissions. Made with high-strength alloy forging technology, its torsional strength and fatigue life far exceed industry standards. Precision spline machining ensures zero-clearance engagement with sliding sleeves and gears, delivering up to 99% transmission efficiency and faster shift response. Factory-grade dynamic balancing suppresses high-speed operation vibration and effectively reduces transmission noise. Suitable for commercial vehicle applications such as heavy-duty trucks and buses, it is a core component ensuring stable power output of the transmission.\"\"<\/p>","protected":false},"excerpt":{"rendered":"

Part No. 1358 304 256 is the mainshaft assembly, designed for ZF 12AS series 12-speed AMT transmissions and serving as the core power transmission component of the gearbox. It features an integrated precision-forged structure with carburized and quenched surface treatment, delivering excellent wear resistance and impact resistance to adapt to various heavy-duty operating conditions. The mainshaft is integrated with mounting positions for multi-speed gears, which work with sliding sleeves and spline sleeves to enable gear shifting. OEM-level dimensional accuracy ensures perfect fit with all matching parts. Replacing this part can restore the transmission’s power transmission performance, extend the overall service life of the gearbox, making it a key original equipment part for commercial vehicle transmission maintenance.<\/p>","protected":false},"featured_media":7297,"template":"","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"%%post_title%%","_seopress_titles_desc":"%%post_excerpt%%","_seopress_robots_index":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[162],"product_tag":[],"class_list":{"0":"post-7168","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-mainshaft-assembly","7":"desktop-align-center","8":"tablet-align-left","9":"mobile-align-left","10":"ast-product-gallery-layout-horizontal-slider","11":"ast-product-gallery-with-no-image","12":"ast-product-tabs-layout-horizontal","14":"first","15":"instock","16":"shipping-taxable","17":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product\/7168","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media\/7297"}],"wp:attachment":[{"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media?parent=7168"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_brand?post=7168"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_cat?post=7168"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_tag?post=7168"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
