1. Ohlins HD 044: Best Overall
In our evaluation, the Ohlins HD 044 stands out for its exceptional damping performance and adjustability. The remote preload adjuster allows you to dial in the perfect sag for two-up riding in seconds, and the progressive rate springs provide a smooth ride over rough roads while preventing bottoming out under heavy loads. Owner feedback consistently praises the dramatic improvement in comfort and handling compared to stock shocks.
However, the premium pricing puts it out of reach for budget-conscious riders. If you rarely ride two-up or prioritize cost savings over peak performance, you may find better value elsewhere. We recommend these shocks for riders who frequently carry a passenger and want the best possible ride quality.
- Remote preload adjuster makes on-the-fly changes easy for two-up loads

- High-quality construction with corrosion-resistant finish
Pros: Excellent ride quality for both solo and two-up; Easy preload adjustment without tools
Cons: Premium price point may be a barrier for some budgets
2. Progressive Suspension 412 Series: Best Value
Based on owner feedback and the spec sheets, the Progressive Suspension 412 Series is a solid choice for riders seeking a cost-effective upgrade. The progressive rate springs offer a balance of comfort and support, and the five-step preload adjuster lets you set sag for two-up loads. Many owners report a significant reduction in bottoming out and improved ride quality on rough roads.
However, the lack of adjustable damping means you cannot fine-tune the ride for different conditions. Riders who demand precise control or ride aggressively may find the 412 Series too soft. We recommend these shocks for budget-minded riders who want a reliable, no-fuss upgrade for occasional two-up trips.
- Progressive springs provide a comfortable ride for solo and two-up
- Five-position preload adjuster accommodates varying loads
- Available in multiple lengths and spring rates for different models
Pros: Affordable upgrade with noticeable improvement over stock; Good load capacity for two-up riding
Cons: Preload adjustment requires tools (spanner wrench); Damping is not adjustable, limiting fine-tuning
3. FOX Racing Shox 49-3101: Best Adjustability
In our evaluation, the FOX Racing Shox 49-3101 offers the most adjustability among the shocks we compared. With separate low and high speed compression damping, riders can dial in comfort for two-up touring or firmness for twisty roads. The remote reservoir helps maintain consistent performance on long rides. Owner feedback highlights the dramatic improvement in control and reduced wallowing under heavy loads.
However, the many adjustment knobs can be overwhelming for those who just want a set-and-forget solution. Additionally, the reservoir requires secure mounting, which adds complexity. We recommend these shocks for experienced riders who enjoy tuning their suspension and regularly carry a passenger.
- Separate low and high speed compression adjusters for precise tuning
- Remote reservoir increases oil volume for consistent damping
- Rebound adjustment allows fine control over return speed
Pros: Exceptional adjustability for fine-tuning ride quality; High-quality damping for spirited riding
Cons: Complex setup may intimidate casual riders; Premium price and reservoir mounting can be a hassle
4. Racetech G3-S: Best for Heavy Loads
Based on manufacturer specifications and owner feedback, the Racetech G3-S is purpose-built for heavy loads. The dual-rate springs provide progressive support that prevents bottoming out even with a passenger and full luggage. The gold valve damping system allows fine-tuning of compression and rebound, giving riders control over the ride quality. Many owners report a significant improvement in stability and comfort when two-up.
However, the custom build process means longer wait times and you must provide accurate rider and passenger weights. If you need shocks immediately or prefer off-the-shelf convenience, these may not be ideal. We recommend the G3-S for riders who frequently carry heavy loads and want a tailored suspension solution.
- Dual-rate springs provide progressive support for heavy loads
- Gold valve damping system offers wide adjustability
- Built to order with rider weight and riding style specifications
Pros: Excellent load capacity for two-up with luggage; Customizable spring rates for specific needs
Cons: Long lead time due to custom build; Higher cost and requires accurate weight input
5. Bilstein 38101-07: Best Durability
In our evaluation, the Bilstein 38101-07 stands out for its robust construction and durability. The monotube design efficiently manages heat, ensuring consistent damping even on long two-up rides. Owner feedback indicates these shocks last many miles without fading. The digressive valving offers a firm but controlled ride that many riders appreciate for stability.
However, the ride can be too firm for those seeking plush comfort, especially on rough roads. Additionally, the lack of preload or damping adjustability limits fine-tuning. We recommend these shocks for riders who prioritize longevity and a sportier feel over pillowy comfort.
- Monotube design dissipates heat for consistent damping
- Digressive valving provides firm control without harshness
- Rugged build with long service life
Pros: Exceptional durability and longevity; Consistent performance under sustained heavy loads
Cons: Firmer ride may not suit comfort-oriented riders; Limited adjustability compared to competitors

This is convenient for two-up riding as you can quickly increase air pressure for extra load. The separate damping adjusters provide some tuning capability. Many owners appreciate the smooth ride and adjustability.
However, air shocks come with potential reliability concerns; leaks can occur, and the system requires periodic checks. Additionally, the initial setup to find the right air pressure and damping settings can be time-consuming. We recommend these shocks for riders who don’t mind occasional maintenance and want the flexibility of air adjustment.
- Air spring allows infinite preload adjustment via air pump
- Separate damping adjusters for rebound and compression
- Lightweight design reduces unsprung mass
Pros: Easy preload adjustment for varying loads; Smooth ride quality when properly set up

Frequently Asked Questions
What is the most important feature for two-up riding shocks?
Preload adjustability is critical because it allows you to set the shock sag to accommodate the extra weight of a passenger. Without proper preload, the bike can sag excessively, leading to poor handling and bottoming out. Look for shocks with easy-to-adjust preload, such as a remote adjuster or tool-free knob.
Can I use stock shocks for two-up riding?
Stock shocks are often designed for solo riding with minimal adjustability. They may not provide enough support for a passenger, resulting in a harsh ride, bottoming out, and reduced stability. Upgrading to aftermarket shocks with higher load capacity and better damping is recommended for regular two-up riding.
How do I choose the correct shock length for my Harley?
Shock length affects ride height and geometry. Measure your existing shocks or consult your bike’s manual. A longer shock can increase ride height and ground clearance, while a shorter one lowers the bike. For two-up riding, consider a length that maintains proper sag and doesn’t compromise handling.
Are air shocks better than coil-over shocks for two-up?
Air shocks offer infinite preload adjustment, making them convenient for changing loads. However, they can be less reliable due to potential air leaks. Coil-over shocks with mechanical preload are often more durable and consistent. The choice depends on your preference for adjustability versus reliability.
Do I need adjustable damping for two-up riding?
Adjustable damping allows you to fine-tune the shock’s response to road conditions and load. While not strictly necessary, it can significantly improve ride quality and control, especially if you frequently vary the load or ride on rough roads. Riders who value comfort and performance will benefit from adjustable damping.
