Their active safety function is absolute: they ensure the straight movement and micrometric alignment of the fork on the sliding sleeve to engage the two gears that experience the highest mechanical torque in the vehicle (starting in first gear and reversing). By eliminating any play, they prevent gear grinding, unexpected gear changes under heavy load, and asymmetrical friction of internal components.<\/p>\n<p data-path-to-node=\"8\">From a sustainable marketing and technical transparency perspective, these slides have been eco-designed to break the cycle of major mechanical failures. Made from advanced anti-friction materials, they act as a sacrificial shield to protect key transmission components (synchros, shift forks, and sliding sleeves). Preventively replacing these guide slides during an overhaul avoids complete gearbox destruction, thus limiting the waste of heavy and energy-intensive metal components to manufacture.<\/p>\n<h3 data-path-to-node=\"10\">Technical specifications and eco-designed architecture<\/h3>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\"><b data-path-to-node=\"11,0,0\" data-index-in-node=\"0\">High-tech alloys and polymers:<\/b> Made from high-density engineering bronze or polymer composites (reinforced PEEK type) offering extreme abrasion resistance.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,1,0\"><b data-path-to-node=\"11,1,0\" data-index-in-node=\"0\">Minimum friction index:<\/b> Optimized surface treatment reduces resistance during selection effort, offering smooth gear changes even during cold starts.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,2,0\"><b data-path-to-node=\"11,2,0\" data-index-in-node=\"0\">Maximum thermal and chemical stability:<\/b> Completely insensitive to Extreme Pressure (EP) additives in gearbox oils and stable against temperature variations (from -40 \u00b0C to +150 \u00b0C).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,3,0\"><b data-path-to-node=\"11,3,0\" data-index-in-node=\"0\">High-tolerance geometry:<\/b> Precision machining ensures a perfect contact surface with the grooves of the slider for a homogeneous distribution of thrust forces.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"13\">Key benefits for your gearbox<\/h3>\n<ul data-path-to-node=\"14\">\n<li>\n<p data-path-to-node=\"14,0,0\"><b data-path-to-node=\"14,0,0\" data-index-in-node=\"0\">Technical security and rigorous locking of reports:<\/b> Ensures a firm, clean, and stable engagement of first gear and reverse.
