GP Suspension 49mm TiN Coated Harley Fork Tubes in 24 7/8" Length
Professional Grade Titanium Nitride Technology, Not Amateur Coatings
Our fork tubes feature genuine Titanium Nitride (TiN) coating applied by Northeast Coating Technologies in Maine - not the cheap decorative gold plating that others pass off as "performance coating." This is authentic aerospace-grade PVD 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 2" over length bagger kit.
Proven Performance Specifications
Extreme Hardness: 2,400 to 2,600 HV - harder than carbide and up to 4 times harder than chrome Low Friction Performance: Coefficient of friction of 0.3 on steel - reducing stiction by over 50% compared to uncoated surfaces Superior Durability: Crystalline ceramic structure that provides exceptional scratch and wear resistance under the harshest riding conditions
Why Our TiN Coating Delivers Superior Results
Genuine Titanium Nitride: Extremely hard ceramic material with 1800-2100 Vickers hardness that creates a protective barrier against nicks, scratches, and sand lines Advanced PVD Process: Applied using physical vapor deposition where pure titanium is converted into gas, reacted with nitrogen in a high-energy vacuum environment - maintaining fork tube integrity while creating an ultra-hard surface Optimal Coating Thickness: Applied at 2-5 microns on working surfaces for maximum performance without brittleness
The Performance You'll Experience
Eliminating Stiction: TiN reduces friction with a coefficient of friction of 0.3 compared to steel-on-steel at 0.7 - allowing your suspension to respond instantly to the smallest road inputs and dramatically improving small bump sensitivity.
Consistent Response: The ultra-hard ceramic surface maintains its properties through temperature extremes and contamination, ensuring your suspension performs exactly as designed every ride.
Long-Term Reliability: TiN coating doesn't begin to oxidize until about 850°F and provides wear resistance that extends component life 2-8 times over uncoated surfaces.
Northeast Coating Technologies Excellence
Our tubes are coated at Northeast Coating Technologies in Kennebunk, Maine - now a full member of the HEF Groupe with access to sophisticated technologies derived from HEF's global research resources. This isn't backyard coating work - this is the same aerospace and medical-grade PVD technology trusted by industries where failure isn't an option.
The distinctive gold appearance isn't just for show - it's the visual signature of genuine titanium nitride coating that delivers measurable performance improvements you can feel.
Don't settle for decorative gold plating that wears off. Experience the difference that professional-grade TiN technology makes in your Harley's suspension performance.
