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:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product\/7168", "targetHints": { "allow": [ "GET" ] } } ], "collection": [ { "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product" } ], "about": [ { "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/types\/product" } ], "wp:featuredmedia": [ { "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media\/7297" } ], "wp:attachment": [ { "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media?parent=7168" } ], "wp:term": [ { "taxonomy": "product_brand", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_brand?post=7168" }, { "taxonomy": "product_cat", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_cat?post=7168" }, { "taxonomy": "product_tag", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_tag?post=7168" } ], "curies": [ { "name": "wp", "href": "https:\/\/api.w.org\/{rel}", "templated": true } ] } }
