Why Upgrade the Factory Mustang Shifter?

The factory shifter was designed for comfort and broad consumer appeal.

Unfortunately, enthusiasts often encounter:

• Long shift throws
• Excessive movement
• Missed 2-3 shifts
• Vague gear engagement
• Reduced confidence during aggressive driving

The Hurst Billet Plus was designed specifically to address these issues.

Reduced Shift Throw

The Hurst Billet Plus utilizes a high-ratio pivot mechanism that shortens gear changes.

Benefits include:

• Faster shifts
• Reduced hand movement
• Improved responsiveness
• More performance-oriented feel

Shorter throws help make the transmission feel tighter and more direct.

Improved 2-3 Shift Performance

One of the most common complaints among TR3650 owners is the occasional missed third gear shift during hard acceleration.

Hurst combats this with:

• Improved shift geometry
• Better centering action
• More positive gate engagement

This helps reduce the likelihood of costly missed shifts.

Billet Aluminum Construction

Unlike many factory shifters, the Hurst Billet Plus uses premium billet components.

Benefits include:

• Increased rigidity
• Improved durability
• Reduced flex
• Long-term reliability

Billet construction also contributes to the shifter’s premium feel.

Adjustable Positive Stops

The Billet Plus includes adjustable positive gear stops.

Advantages include:

• Transmission protection
• Reduced over-travel
• Improved shift consistency
• Enhanced durability

This feature is particularly useful for spirited driving and track use.

Precision Shift Feel

Drivers often report:

• Better gate definition
• Increased shift confidence
• More precise engagement
• Improved feedback

The transmission feels significantly more mechanical and connected.
