GP 43MM Softail Fork Tubes
GP 43MM Softail Fork Tubes
These tubes will work with Stock length, Plus 1", and Plus 2" Cartridge kits
True Diamond-Like Carbon Technology
Our fork tubes feature genuine CERTESS Carbon DLC coating -- 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.
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.
Our tubes are coated by a company part of the HEF Group with state-of-the-art TSD 850 PVD/PACVD machines using patented HEF technology. This isn't backyard PVD work - this is aerospace and medical-grade surface treatment technology.
Don't settle for cheap PVD coatings that wear off. Experience the difference that genuine DLC technology makes in your suspension performance.
Amateur Coatings
Our fork tubes feature genuine Titanium Nitride (TiN) coating -- 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.
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.

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.
