TOFR 41mm Hard Chrome Front Fork Tubes (45972-09)
For Harley-Davidson Touring lines from 1984 to 2013, this 41 mm fork tube set is designed to replace part # 45972-09. It features a stainless steel core with a hard chrome surface, offering durability and corrosion resistance. The tubes measure 41 mm in outer diameter and 20 7/8 inches in length (approximately 530 mm), making them compatible with Electra Glide, Street Glide, Road Glide, and Road King models identified by Harley’s OEM specs. The combination of robust hard chrome plating and stainless steel construction aims to provide a smoother ride and longer service life under standard highway use and demanding terrain. Consider alignment and right-length compatibility for your specific model year before installation.
KCINT Stock Length 41mm Fork Tubes (OEM 45417-84)
These KCINT 41 mm fork tubes are listed as stock-length replacements for the OEM part 45417-84. They come in a length of 24 1/4 inches with hard chrome plating for durability and resistance to wear. The 41 mm outer diameter ensures compatibility with 41 mm forks on Harley-Davidson touring and related models. Installers should verify the exact tube length required by their fork leg and ensure proper sealing and dust shield fitment. This option emphasizes straightforward replacement for riders seeking OEM-like performance and longevity.
TOFR 41mm Hard Chrome Front Fork Tubes (DLC Surface)
This TOFR option mirrors the 41 mm diameter requirement with a dual surface approach: hard chrome plus a DLC (diamond-like carbon) coating. The combination aims to reduce wear, improve lubricity, and extend service intervals for Harley Touring models from 1984–2013. The tubes are 41 mm OD with a 20 7/8 inch length (530 mm). DLC coating can reduce friction and improve resistance to abrasion, making it a favorable choice for riders who encounter rougher roads or aggressive riding styles. Always confirm the model year and fork leg compatibility before purchasing.
TOFR 41mm Fork Tubes 3″ Extensions
These 41 mm fork end extensions by TOFR provide an easy way to gain additional front-end height on compatible Harley models such as Wide Glide, Road Glide, Electra Glide, and Road King with 41 mm forks. Made from aluminum 6061 T6 with a nitrile finish, the extensions offer a simple, lightweight method to alter stance and rake characteristics without changing the full fork length. The anodized silver finish provides corrosion resistance while preserving a clean appearance. Check that your fork tubes can accommodate the extension length and confirm clearance with fenders and brakes during installation.
HardDrive 94172 41 mm Fork Tubes — 6″ Over
This HardDrive offering provides a 41 mm fork tube option with a 6″ over extension. The length variation is designed for riders seeking a more aggressive stance or those aiming to accommodate taller tires, heavier loads, or particular suspension tuning preferences. The exact OE reference alignment can vary by year, so confirm compatibility with your specific Harley-Davidson model and fork assembly before ordering. Proper installation and torque specs are essential for safety and performance.
Buying Guide: Key Considerations When Choosing 41 mm Fork Tubes
- Compatibility: Verify model year, OEM part numbers, and fork leg length. Harley-Davidson Touring bikes have varied specs across years; ensure the tubes match your forks’ inner diameter, outer diameter, and length.
- Finish and durability: Hard chrome plating offers good wear resistance; DLC coatings reduce friction and wear for extended service life. Consider riding conditions and maintenance frequency when selecting surface treatment.
- Length and height: Standard length (around 20 7/8 inches) versus extended options affect front-end height, rake, and steering feel. Mis-matched length can cause handling issues or clearance problems.
- Extensions and lifts: Extensions add height but may require additional hardware and install adjustments. Confirm fender, brake line, and wheel clearance after installation.
- Installation and maintenance: Replacements often require proper torque specs, seals, and alignment. For some models, professional installation is recommended to ensure perfect fit and safe operation.
- OEM vs aftermarket: OEM-like tubes offer proven fit but may limit customization. Aftermarket options can provide DLC coatings or unique finishes but verify exact compatibility.
- Pricing and warranty: Consider warranty terms and return policies. While not listing prices here, compare total cost of ownership including installation and potential rework.
The selections above focus on 41 mm tubes suitable for Harley-Davidson touring family and other 41 mm fork systems. When evaluating options, prioritize compatibility, tube length, plating or coating choice, and the overall impact on ride quality and fork service intervals. Always consult your service manual and, if in doubt, engage a qualified technician for installation to ensure optimal performance and safety.
