1358 203 219 Left Countershaft Assembly, adopting original factory precision forging process, made of high-strength and fatigue-resistant material. It is carburized and quenched for high hardness, featuring strong bending and torsion resistance, precise transmission fit clearance, stable operation and low noise. Suitable for heavy-duty and long-distance high-intensity working conditions, wear-resistant and not easy to deform. It has high installation matching degree without secondary trimming, effectively improving the transmission efficiency and overall service life of the gearbox. Matches ZF 12TX2421TD 12-speed AMT automatic gearbox.\"\"<\/p>","protected":false},"excerpt":{"rendered":"

1358 203 219 Left Countershaft Assembly is forged from high-strength alloy steel and processed by precision carburizing and quenching heat treatment. It features excellent bending and torsion resistance with precisely ground gear teeth for tight meshing and stable transmission. It withstands long-term high-torque heavy-load operation and resists tooth breakage, deformation and wear. Fully matched to original specifications with no secondary trimming required, it delivers low noise and long service life, suitable for ZF 12TX2421TD 12-speed AMT automatic transmission.<\/p>","protected":false},"featured_media":7256,"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":[163],"product_tag":[],"class_list":{"0":"post-7253","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-countershaft-assembly-layshaft-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\/7253","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\/7256"}],"wp:attachment":[{"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/media?parent=7253"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_brand?post=7253"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_cat?post=7253"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ql-autoparts.com\/ru\/wp-json\/wp\/v2\/product_tag?post=7253"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
