• Aerospace & race-spec materials throughout

• Upgraded contactless Hall Effect sensors for zero-wear accuracy

Premium Sim Racing Performance

The Bazooka design has been reimagined with tighter tolerances, smoother mechanical motion, and the unmistakable rally-inspired throw.

• Inspired by Ford Escort MKII rally-car shift mechanics

• Ultra-precise Hall Effect sensors—no wear, no drift

• Dedicated H-pattern mechanism for confident, positive engagement

• Direct USB-C connection with zero input lag

• Fully customizable 8-gate layout for multiple vehicle types

Designed for competitive drivers who rely on repetition, rhythm, and mechanical consistency.

Professional Sim Racing Engineering

The H1 is engineered to withstand years of high-force shifting and training use:

• 3.5kg full-metal housing using aerospace-grade HE260 aluminum

• All-steel gear teeth and stainless steel gate pegs

• Self-lubricating bronze bushings for long-term smoothness

• Race-inspired detent system with adjustable resistance

• Multiple mounting options for all major rigs

Everything is overbuilt—because it should feel like the real thing.

Back by Popular Demand

The BDH H1 returns because the sim racing community asked for it.
The original Bazooka earned a cult following thanks to its mechanical clarity, durability, and unmistakable feedback.
This new H1 honors that legacy with refined engineering, updated electronics, and enhanced materials—all while preserving the raw character that made the original so loved.

Dedicated H-Pattern Mechanism

Unlike dual-mode shifters, the H1 is 100% purpose-built for H-pattern.
Every component—shafts, cams, springs, bushings, detents—is optimized for:

• Absolute gate clarity

• Direct mechanical communication

• Precise gear engagement

• No ambiguity between gears

You always know exactly where you are in the gate.

Modern Hall Effect Sensor Integration

The original H1 used microswitches.
The new H1 uses contactless Hall Effect sensors, providing:

• No mechanical wear

• Ultra-consistent accuracy

• Zero-latency signal processing

• Improved long-term durability

These sensors are backed by the lifetime warranty—because they’re built to last.

Comprehensive Lifetime Warranty

Every BDH H1 is protected by a lifetime warranty covering manufacturing defects, materials, and assembly quality.
This level of confidence reflects the shifter’s uncompromising construction and BDH’s commitment to engineering excellence.
