▶ Understanding External Bypass Shocks (Diagram)

/// External bypass shock is a position-sensitive shock absorber that uses external bypass tubes to control hydraulic oil flow throughout different stages of the suspension's travel. Unlike a conventional shock, which uses a single damping circuit throughout its travel, an external bypass shock uses multiple independently adjustable damping zones to control suspension performance throughout the stroke.

Each bypass tube controls hydraulic oil flow within a specific damping zone of the shock's travel, allowing suspension performance to be independently tuned throughout compression and rebound. This provides precise control over damping characteristics as the shock moves through its stroke.

By adjusting each bypass valve, damping can be precisely tuned throughout the shock's travel to optimize low-speed and high-speed suspension performance while providing controlled bottom-out and top-out resistance for the intended vehicle application.

/// Compression damping controls how the suspension reacts as the shock compresses. Compression bypass adjusters face downward because hydraulic oil flows through the compression circuit only during compression.

Each compression bypass tube is positioned to control a specific portion of the shock's travel. Closing a compression bypass valve restricts oil flow, increasing compression damping within that zone and making the suspension more resistant to compression. Opening the valve allows more oil to bypass the piston, reducing compression damping and allowing the suspension to compress more freely.

Because each compression tube controls its own section of travel, damping characteristics can be progressively tuned throughout the suspension stroke instead of remaining the same from beginning to end.

/// Rebound damping controls how the suspension reacts as the shock extends after being compressed. Rebound bypass adjusters face upward because hydraulic oil flows through the rebound circuit only during rebound.

Each rebound bypass tube is positioned to control a specific portion of the shock's travel. Closing a rebound bypass valve restricts oil flow, increasing rebound damping within that zone and slowing suspension extension. Opening the valve allows more oil to bypass the piston, reducing rebound damping and allowing the suspension to extend more freely.

Proper rebound tuning helps maintain tire contact with the terrain, improves vehicle stability, and prevents the suspension from extending too quickly after an impact.

/// Overlapping Bypass Zones

Each bypass tube is positioned to control a specific section of the shock's travel, but those sections are not always independent. When two bypass tubes overlap, both bypass circuits are active within that portion of the stroke.

Instead of one bypass tube abruptly handing control to another, their damping characteristics blend together as the suspension moves through the overlap. This creates smooth transitions between damping zones while allowing each section of the suspension travel to be tuned independently.

By combining multiple bypass tubes with overlapping zones, an external bypass shock can deliver a suspension that remains compliant during normal operation while progressively increasing control where additional damping is needed.

/// External Bypass vs. Internal Bypass

Both external and internal bypass shocks are position-sensitive and are designed to change damping characteristics throughout the shock's travel. The difference is how that control is achieved.

An external bypass shock routes hydraulic oil through adjustable bypass tubes mounted to the outside of the shock body. Each bypass tube can be individually tuned, allowing compression and rebound damping to be adjusted externally without disassembling the shock.

An internal bypass shock achieves the same position-sensitive principle using internal bypass ports machined into the shock body. The damping zones are built into the shock's internal design, providing a compact package with fewer external components, but changing the damping characteristics typically requires internal disassembly and revalving.

/// External Bypass Shocks provide fully independent external adjustment of compression and rebound damping, making them the preferred choice when maximum tuning flexibility is desired.
