Introducing the Brian Crower BC9340: The Definitive Solid Bucket Conversion for the Can-Am X3
For the serious Can-Am Maverick X3 enthusiast pushing the boundaries of performance, the factory hydraulic lash adjuster (HLA) valve train represents a critical ceiling. At sustained high RPM—the realm where peak horsepower is forged—these hydraulic components can pump up, float, and ultimately limit valve control, robbing you of power and jeopardizing engine integrity. The Brian Crower BC9340 Can-Am X3 Solid Bucket Conversion Kit is engineered to demolish this barrier. This isn’t an incremental upgrade; it’s a fundamental transformation of your engine’s valve train from a compliant, RPM-sensitive system into a precise, rigid, and ultra-reliable mechanical assembly. By replacing the stock hydraulic lifters with precision-machined solid buckets and matching solid camshafts, the BC9340 kit unlocks consistent valve timing at any engine speed, enabling you to safely exploit higher RPM ranges and more aggressive cam profiles for transformative gains in horsepower and throttle response. This is the cornerstone modification for turbocharged, high-compression, or race-built X3 engines where valvetrain stability is non-negotiable.
Engineered Advantages: The Core Benefits of a Solid Valve Train
Converting to a solid lifter system with the BC9340 kit provides a multitude of performance and reliability benefits that directly address the limitations of the stock setup. This is a systematic upgrade designed for those who understand that power is built on a foundation of control.
- Eliminates HLA Pump-Up & Float: The primary nemesis of high-RPM power. Solid buckets cannot compress under pressure, ensuring the cam lobe always maintains exact, predictable contact with the valve. This guarantees the valve opens and closes precisely as the cam dictates, regardless of engine speed.
- Enables Higher, Stable RPM Limits: With the danger of valve float virtually eliminated, your engine can safely sustain higher RPM. This allows you to capitalize on powerbands that extend further, making more horsepower and keeping the engine in its peak power zone under acceleration.
- Unlocks Aggressive Camshaft Profiles: High-performance, high-lift camshafts often have ramp rates and profiles that can cause hydraulic lifter collapse or pump-up. The solid conversion is a prerequisite for running the most radical cam profiles from Brian Crower or other manufacturers, allowing for greater air flow and more radical power curves.
- Ensures Consistent Valve Lash & Timing: Valve lash is set manually during installation and remains a fixed, mechanical specification. This consistency ensures optimal valve opening/closing events 100% of the time, leading to more stable combustion, better idle quality, and predictable performance.
- Increases Durability Under Extreme Conditions: Built from high-grade materials, the solid buckets and cams are designed for the intense heat and stress of high-performance use. This translates to exceptional longevity and resistance to wear, especially in forced-induction applications where under-hood temperatures are extreme.
- Foundational for Maximum Forced Induction Power: For turbocharged or supercharged X3 builds pushing significant boost, valve train control is paramount to prevent valve float under high cylinder pressure. The BC9340 kit provides the rigid platform needed to contain this power reliably.

Installation Precision & Engineering Philosophy
Installing the BC9340 kit is a technical procedure that demands mechanical skill, precision measuring tools, and a thorough understanding of engine timing. It is not a simple “bolt-on” but a “build-in” modification. The core task is setting the valve lash. This involves measuring the gap between each valve stem and its corresponding solid bucket with a feeler gauge, then selecting the correct thickness shim from the provided kit to achieve the specified clearance (typically between 0.15mm-0.20mm for intake and 0.20mm-0.25mm for exhaust, but always consult the official Brian Crower installation sheet for exact specs). This manual setting is what gives the system its stability. Unlike a hydraulic system that self-adjusts (and can over-adjust), this lash remains constant, providing a rigid, predictable link between cam and valve. For a deep dive into the engineering rationale behind solid lifters in high-performance applications, refer to this authoritative technical resource on valvetrain fundamentals at EngineLabs. Proper break-in procedures for the new camshafts and lifters are also absolutely critical to ensure long-term performance and wear characteristics.
Vehicle Fitment & Application Notes
The Brian Crower BC9340 Solid Bucket Conversion Kit is engineered specifically for the heart of the modern high-performance side-by-side. Correct fitment is essential for proper operation.
Primary Fitment:
• Can-Am Maverick X3 (all models with the 900 ACE Turbo engine) – 2017, 2018, 2019, 2020, 2021, 2022, 2023 Model Years.
• This includes Turbo, Turbo R, Turbo RR, Max, and X RS models.
Critical Compatibility Notes:
• Engine Verification: Confirm your X3 is equipped with the 900cc twin-cylinder ACE Turbo engine (engine code C93M). This kit is not for the non-turbo 900cc or other engine families.
• Camshaft Profiles: The included camshafts are performance-oriented. Their specific duration, lift, and lobe separation angle will influence the powerband (e.g., more top-end, improved mid-range). Verify the exact cam profile provided in the kit for your tuning strategy.
• Tuning Required: Installing this kit, especially with altered camshaft profiles, will require a custom ECU tune from a reputable Can-Am tuner. The engine’s air/fuel ratios, ignition timing, and potentially idle control strategies must be recalibrated to match the new valve timing and airflow characteristics. Do not run the engine without proper tuning.
The Ultimate Foundation for X3 Performance
The BC9340 Solid Bucket Conversion Kit transcends the category of a simple parts upgrade. It is a fundamental re-engineering of a critical engine system, moving it from a production-compromised design to a race-proven architecture. For builders targeting reliable power beyond 200 horsepower, for those frequently bouncing off the rev limiter in dunes or deserts, or for anyone demanding absolute valvetrain certainty, this conversion is not just an option—it is an imperative. It lays the unshakable groundwork upon which all other power-adders (bigger turbos, ported heads, advanced fuel systems) can securely stand. Partnered with quality installation and professional tuning, the Brian Crower BC9340 doesn’t just modify your Can-Am X3; it transforms its very character, delivering the precise, responsive, and resilient heart of a true performance machine.
