GP Suspension Market Share Analysis for June 2026

GP Suspension DLC Coated 49mm Harley Fork Tubes in 22 7/8" Length True Diamond-Like Carbon Technology, Not Cheap Imitations Our fork tubes feature genuine CERTESS Carbon DLC coating applied by Northeast Coating Technologies in Maine - not the cheap PVD coatings that others pass off as "DLC." This is authentic diamond-like carbon technology from HEF Group, the global leader in advanced surface treatments. Use: OEM bottoming assembly has been removed. Tubes are ready for installation of GP Suspension 25mm cartridge kit for a stock length bagger kit.  Uncompromising Performance Specifications Hardness: 2,500 to 6,000 HV - up to 20 times harder than chrome Ultra-Low Friction: Coefficient of friction as low as 0.10 in dry conditions, less than 0.10 when lubricated - dramatically reducing stiction and improving suspension response Extreme Durability: Diamond crystal structure with SP3 bonding creates a surface that will never wear out under normal use Why Our DLC Coating is Superior Real Diamond-Like Carbon: Combines the hardness of diamond (1,500-3,200 HV) with friction coefficients 5-10 times lower than conventional hard coatings Advanced PACVD Process: Applied at only 170°C using plasma-enhanced chemical vapor deposition - maintaining the integrity of your fork tubes while creating an incredibly dense, chemically inert surface Multi-Layer System: Includes multiple sublayers (Cr, CrN, WC-C) with a top layer of amorphous carbon for optimal adhesion and performance The Difference You'll Feel Eliminating Stiction: The ultra-low friction surface allows your suspension to respond to the smallest inputs, dramatically improving small bump sensitivity and overall ride quality. Consistent Performance: Excellent friction properties with no dimensional changes - your suspension works exactly as designed, every time. Lifetime Durability: This isn't a coating that wears off. The diamond-like carbon structure is so hard and wear-resistant that it will outlast your motorcycle. Northea
