HST 2.0 Flow Kit – Experience True Connected Carving

A Decade in the Making

For years, riders requested more connectedness and flow in their trucks. Space constraints inside the HST baseplate made traditional solutions impossible—until now. After ten years of development, we've engineered a breakthrough that fundamentally changes how HST Trucks respond throughout their range of motion.

The Innovation: Progressive Compression Technology (Patent Pending)

The HST 2.0 Flow Kit introduces a revolutionary cast polyurethane compression bushing positioned inside our strongest spring. When you carve, the wave cams and hanger compress the bushing against the baseplate, creating a non-linear response that gets progressively more supportive as you lean deeper. Instead of hitting a hard stop at maximum lean, you'll feel a smooth, cushioned transition that keeps you connected to your board throughout the entire turn. This breakthrough is significant enough that we've applied for a new patent.

Complete System Redesign

We didn't stop at the bushing. Every component has been reimagined:

• Fiber-reinforced nylon wave cams – Incredibly strong with permanently bonded cam keys
• Precision-engineered 85mm kingpins – Precisely threaded to prevent over-tightening
• Molybdenum-impregnated nylon washers – Self-lubricating, durable, and virtually silent
• Optimized dimensions and materials throughout for maximum performance

What You'll Experience

• Connected flow – Smooth, progressive response from center to maximum lean
• No hard stops – Cushioned transitions at the extremes of your carve
• Precise handling – Responsive control exactly when you need it
• Wide tunability range – Dial in your perfect setup
• Full board lean – All the carving performance HST Trucks are known for

The difference is immediate. Your trucks will feel better than new.

Choose Your Configuration

Flow Kit (No Springs)

Perfect if you already have springs you love or want to purchase them separately. Includes all upgraded internal components.

Flow Kit with Silver Springs

Spring Rate: 2,700 lbf/in
Recommended for shorter (45 inches and below) and narrower decks like traditional longboards. Ideal for riders seeking responsive carving with enhanced connectedness.

Flow Kit with Gold Springs

Spring Rate: 2,900 lbf/in
Recommended for long (45 inches and above) or wide decks. Our strongest compression springs deliver maximum support for bigger boards and aggressive riding.

Note: If your HST Trucks are more than five years old, we recommend upgrading to new springs to maximize performance.

What's Included (Services Two Trucks)

• 2 × 85mm precision kingpins
• 2 × Molybdenum-impregnated nylon washers
• 2 × Fiber-reinforced nylon wave cam sets with bonded cam keys
• 2 × Cast polyurethane compression cone bushings
• 1 × Kingpin hex tool
• 1 × Wave cam lubricant packet (3cc)
• 2 × Springs (Silver or Gold configuration only)

Easy Adjustment

Assembly is simple: tighten the kingpin until it just begins to show through the locknut. After your first ride, fine-tune the tightness to dial in your preferred feel. You'll be amazed at the range of adjustment the Flow Kit provides.

Universal Compatibility

The Flow Kit is fully compatible with:

• All versions of HST Trucks
• Original Skateboards S8 trucks

Upgrade any HST setup with confidence.
