Suspension Upgrades for Harley Davidson Touring Family
Engineered for the long-distance haul. These iconic models demand exceptional load management and comfort to support two-up riding and fully-laden luggage over extended trips.
The Limits of Stock Suspension
- Load Management Failure: Factory suspension struggles with two-up riding and luggage, leading to frequent bottoming-out and unpredictable handling over highway undulations.
- Ride Harshness: Lack of refined compression damping translates into sharp jolts and discomfort when encountering square-edged bumps and expansion joints.
Kingham Tech Engineering Advantage
- Hydraulic Preload Adjustability: Integrating a hydraulic system for quick, tool-free adjustment of sag, ensuring optimal ride height is maintained regardless of passenger or luggage weight.
- Nitrogen-Charged Monotube Design: Utilizing a single-tube design with nitrogen charge for superior heat dissipation and consistent, fade-free damping throughout long-distance cruising.

Performance Deficiencies of Stock Unit
High-Speed Instability: The frame and stock suspension struggle with the engine’s power output at speed, causing excessive wobble, especially in sweeping corners.
Limited Cornering Capability: Restricted ground clearance and poor rebound control limit lean angle, forcing riders to reduce speed significantly through turns.
Kingham Tech Engineering Advantage
Performance Monotube Shocks (Rear): High-end monotube design with adjustable rebound and compression to deliver aggressive cornering capability and precise chassis control.
Increased Ground Clearance: Specific shock lengths are available to raise the ride height, maximizing lean angle potential and preventing scraping under spirited riding.
Performance Solutions for Harley Davidson Dyna
Engineered for power and aggressive riding. Celebrated for its powerful engine, unique handling, and strong presence in the custom bike scene, the platform demands stability for high-speed riding.

Suspension Upgrades for Harley Davidson Sportster
Engineered for agility and urban performance. This lightweight, versatile model is the perfect foundation for custom builds, demanding suspension that sharpens cornering precision and provides a more controlled, planted feel.
The Limits of Stock Suspension
Harsh Ride & Low Travel: Stock units often have limited travel and simplistic damping, resulting in a harsh, uncomfortable ride that struggles with everyday road imperfections.
Cornering Imprecision: The lack of refined damping control causes excessive chassis movement, leading to vague steering input and reduced confidence when leaned over.
Kingham Tech Engineering Advantage
Enhanced Damping Rod Kit (Front): Front suspension upgrades utilize superior valving technology to improve hydraulic control, eliminating front-end bounce and dive without sacrificing comfort.
Progressive Rate Springs (Rear): Rear springs are engineered with a progressive rate curve to improve small bump absorption while maintaining the low-profile stance desired by custom builders.

FAQ
How do Kingham shocks improve Touring models' comfort during long-haul riding under load?
Our upgraded shocks integrate Hydraulic Preload Adjustability, allowing quick calibration to manage two-up riding and luggage, eliminating bottoming-out and maintaining stable ride height, thereby reducing long-haul fatigue.
Do I need to lift my Sportster to install Kingham performance shocks?
No. Our Sportster solutions provide multiple length options, including custom specifications that maintain the low-profile stance. We provide progressive springs to improve comfort without sacrificing your desired custom look.
Why does my Dyna model require performance monotube shocks?
The Dyna platform has powerful output, but the stock suspension is prone to instability during high speeds or aggressive cornering. Performance monotube design with adjustable damping delivers precise chassis control and anti-wobble capability, maximizing cornering lean angle.
Do your shocks require professional installation, or can I install them myself?
Our shocks are designed for direct, seamless bolt-on installation. However, due to the critical nature of suspension components, we strongly recommend professional installation and final setup by a certified tuning shop.
What types of business partnerships does Kingham Tech offer?
We offer three main tracks: Product Distribution, OEM/ODM Solutions (for custom manufacturing), and Strategic Partner Programs (for race teams and technical collaboration).
How to ensure I select the correct shock specification for my Harley-Davidson model?
Please provide the motorcycle’s VIN (Vehicle Identification Number) and submit your inquiry via the contact form to our engineering team. The engineering team will verify the correct specifications and compatibility to guarantee 100% component fitment.
