Flynsu Gated Pro Stick Shifter replacement for B&M 81052 — Magnum Grip, 2/3/4-Speed modular gate & one-handed reverse lockout

Flynsu's replacement shifter reproduces the B&M 81052 Pro Stick with a stealth magnum grip, a reversible gate and one-handed reverse lockout for NHRA/IHRA-style performance.

This direct-fit replacement shifter is designed to give you the same feel and function as the B&M Pro Stick 81052 while working with a wide range of automatic transmissions. Its modular gate system accepts plates for 2-, 3- or 4-speed configurations, and the ergonomic magnum grip is compatible with forward and reverse shift patterns. Built to fit many GM, Ford and domestic transmissions, the unit focuses on repeatable gate action, secure reverse lockout and an easy install for restorations and race builds.

How does the reverse lockout make one-handed operation safer?

The reverse lockout is engineered to require a deliberate single-hand action to select reverse, preventing accidental engagement while driving. It meets common drag-racing safety guidelines so it’s suitable for both street and sanctioned track use. The mechanism is positive and tactile, giving a clear engagement point.

• One-handed reverse release for quick operation
• Positive mechanical lock to prevent accidental reverse
• Designed to meet NHRA/IHRA style safety expectations

This Flynsu unit is built as a replacement for the B&M 81052 and fits many common automatic transmissions found in domestic vehicles. It’s compatible with multiple GM models and a broad range of Ford and Chrysler automatics when used with the proper linkage. Verify fitment with your vehicle’s transmission model before ordering.

What does the modular quick-change gate system offer?

The modular gate design accepts optional plates so you can switch between 2-, 3- or 4-speed patterns without replacing the whole shifter. That makes it useful for builders who change transmission types or for restorations requiring period-correct shift patterns. The quick-change plates snap into place and preserve consistent gate feel.

• Interchangeable gate plates for 2/3/4-speed patterns
• Easy removal and installation—no permanent modifications
• Consistent, repeatable gate action after plate changes

How does the magnum grip improve shifting ergonomics?

The magnum-style grip is shaped for a secure, comfortable handhold whether you’re running forward or reverse patterns. Its contours reduce hand fatigue during repeated shifts and provide precise palm placement for consistent gate engagement. The texture and size are tuned for positive feel under both street and track conditions.

• Ergonomic profile for secure hand placement
• Compatible with forward and reverse shift patterns
• Designed for consistent tactile gate engagement
