This ZF 1358 304 222 mainshaft 2nd gear is specifically built for ZF 12-speed AMT transmissions. Forged from high-strength alloy and treated with precision carburizing and quenching, it features high tooth surface hardness, excellent wear resistance and impact resistance, capable of withstanding frequent shift shocks under heavy-duty operating conditions. Factory-grade precision tooth profile machining ensures uniform meshing clearance, delivering smooth 2nd gear shifts without gear rattling noise, high transmission efficiency, and effectively reducing transmission noise. Ideal for heavy-duty commercial vehicle applications, it is a core component for stable power transmission in the gearbox. Its original quality ensures a perfect fit with the mainshaft, enabling hassle-free one-step replacement during maintenance.\"\"\"\"<\/p>", "protected": false }, "excerpt": { "rendered": "

Part No. 1358 304 222 is the mainshaft 2nd gear, compatible with the ZF 12AS series 12-speed AMT transmission. Mounted on the transmission mainshaft, it serves as a key component for power transmission in 2nd gear.<\/div>\n
<\/div>\n
The gear is integrally forged from high-alloy steel with precision grinding on the tooth surfaces. Manufactured in strict accordance with OEM tolerance standards, it ensures accurate meshing with the mainshaft and sliding sleeve.<\/div>\n
<\/div>\n
Suitable for commercial vehicles such as heavy-duty trucks and buses, it withstands high torque impact during starting and low-speed heavy-load operation, resisting tooth breakage and wear during long-term service. Replacement restores the shifting performance of the transmission 2nd gear, eliminates jamming and abnormal noise, and guarantees driving safety.<\/div>", "protected": false }, "featured_media": 7174, "template": "", "meta": { "_seopress_robots_primary_cat": "", "_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-7186", "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-tabs-layout-horizontal", "13": "first", "14": "instock", "15": "shipping-taxable", "16": "product-type-simple" }, "_links": { "self": [ { "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product\/7186", "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\/7174" } ], "wp:attachment": [ { "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media?parent=7186" } ], "wp:term": [ { "taxonomy": "product_brand", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_brand?post=7186" }, { "taxonomy": "product_cat", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_cat?post=7186" }, { "taxonomy": "product_tag", "embeddable": true, "href": "https:\/\/www.ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_tag?post=7186" } ], "curies": [ { "name": "wp", "href": "https:\/\/api.w.org\/{rel}", "templated": true } ] } }
