Flynsu Replacement Stick Shifter — Stealth Magnum Grip, One-Hand Reverse Lockout & Modular 2/3/4-Speed Gate

Flynsu’s replacement shifter replicates the B&M 81052 Pro Stick with a Stealth Magnum grip, offering one-handed reverse lockout and modular gate plates for 2-, 3- or 4-speed automatic transmissions.

This direct-fit replacement is built for hobbyists and mechanics who need a reliable, ergonomic stick shifter that accepts common changeable gate plates and suits a long list of domestic automatic transmissions. It matches the Pro Stick’s function—reverse lockout, solid gated action and magnum-style handle—while fitting many GM, Ford, Chrysler and AMC applications. If your vehicle uses a TH400, 700R4, 4L60 series or classic Ford C4/C6, this Flynsu unit is intended as a drop-in style alternative.

How does the reverse lockout make shifting easier?

The built-in reverse lockout lets you operate the shifter with a single hand while preventing accidental engagement of reverse. It complies with NHRA/IHRA safety requirements and keeps reverse isolated until intentionally released. That delivers safer, cleaner gear selection during aggressive launches or everyday use.

• One-handed release design for fast, secure shifting.
• Meets common drag-racing safety standards (NHRA/IHRA).
• Positive mechanical lock reduces mis-shifts into reverse.

Will this shifter fit my transmission and vehicle?

The Flynsu replacement is engineered to be compatible with many popular automatic transmissions and domestic makes. It’s described as suitable for GM TH400, 350, 250, 200 and 700R4 families as well as 4L60/4L60E/4L65E/4L80E variants, plus Ford C4/C6 and several Chrysler/AMC setups. Always check bolt pattern, linkage style and transmission-specific adapters before ordering to ensure correct fitment.

• Designed for a wide range of GM gearboxes and Ford C4/C6 units.
• Works with Chevy, AMC and Chrysler applications where the Pro Stick fits.
• Confirm vehicle-specific linkage and mounting dimensions before installation.

What adjustments and configurations are available?

The shifter uses a modular gate system so you can swap quick-change plates for 2-, 3- or 4-speed patterns without replacing the whole assembly. The magnum-style grip accepts both forward and reverse shift patterns so the lever orientation stays comfortable for different installation layouts. Its precise gated action helps maintain consistent shift positions lap after lap or drive after drive.

• Interchangeable gate plates for 2/3/4-speed setups.
• Ergonomic magnum grip usable in either shift orientation.
• Firm gate detents for repeatable, tactile shifting feedback.

How hard is installation and maintenance?

Installation is straightforward for anyone familiar with aftermarket shifters—typical steps include mounting to the vehicle’s shifter bracket, connecting the transmission linkage and confirming gate plate alignment. Maintenance is minimal: keep pivot points lubricated and check fasteners periodically. Replacement gate plates or the grip can be swapped quickly if you change transmission type or user preference.

• Mounts to standard Pro Stick-style brackets and linkage systems.
• Routine lubrication and torque checks keep operation smooth.
• Quick-change components simplify future adjustments or upgrades.

Who this is for: Drivers restoring classic muscle cars, racers needing a compliant reverse lockout, and enthusiasts upgrading stock shifters will value this Flynsu replacement. It’s aimed at users who want the look and mechanical feel of a Pro Stick–style shifter with modular gate options and broad transmission compatibility. If you require a direct replacement with racing-grade safety features and tactile gated shifting, this unit is a practical choice—just confirm fitment for your specific transmission model and linkage setup before purchase.
