Swift Springs Introduces the 2nd Generation Fox Shock Stack Guide

Improve Spring Stack Alignment and Suspension Consistency with the New SST-F2 Stack Guide

As suspension setups become increasingly refined, even the smallest amount of unwanted movement can affect consistency on the race track. That's why Swift Springs continues expanding its Suspension Tuning Accessories lineup with the release of the Second Generation Fox Shock Stack Guide (SST-F2).

Designed specifically for the latest Fox Shock thread design, the new SST-F2 helps racers maintain proper spring stack alignment, reduce unwanted movement, and improve repeatability throughout the suspension's working range.

Whether you're chasing more consistent shock performance or building a more repeatable setup, the SST-F2 is designed to help eliminate one of the most overlooked sources of inconsistency.

Why Does a Shock Stack Guide Matter?

A stack guide plays a critical role in keeping the spring stack properly aligned as the suspension cycles through its travel.

Without proper guidance, small amounts of side movement or clearance between components can introduce unnecessary deflection into the spring stack. While these movements may seem minor, they can create inconsistencies that make suspension tuning more difficult from one session—or one race—to the next.

The goal isn't simply to hold the springs in place.

It's to help the entire spring stack move smoothly and consistently through its intended travel.

Designed Specifically for the Latest Fox Shock Thread Design

The SST-F2 was engineered to fit the newest generation of Fox Shock bodies while expanding Swift Springs' growing lineup of suspension tuning accessories.

When paired with the Swift Springs Aluminum Adapter, the Stack Guide helps reduce excess clearance between the adapter and the shock body.

This tighter, more controlled fit helps:

• Maintain spring stack alignment
• Reduce unwanted spring deflection
• Promote smoother linear spring movement
• Improve suspension repeatability
• Help deliver more consistent stack load characteristics

For racers making small suspension adjustments, improving repeatability can make tuning changes easier to evaluate and duplicate.

Built for Today's High-Performance Suspension Packages

Modern racing suspension systems demand precision.

Whether competing in asphalt or dirt applications, today's racers rely on predictable suspension movement to maximize grip and maintain consistent chassis balance throughout a race.

The Second Generation Fox Shock Stack Guide was developed to complement these evolving suspension packages by helping minimize unnecessary movement within the spring stack.

Rather than fighting inconsistencies caused by component clearance, racers can focus on making meaningful tuning adjustments with greater confidence.

Key Features of the SST-F2 Stack Guide

The new SST-F2 offers several performance-focused advantages:

• Designed for the latest Fox Shock thread design
• Maintains proper spring stack alignment
• Works with the Swift Springs Aluminum Adapter
