Welcome to the premier destination for GM Genuine Parts sprockets, where precision engineering meets powersports reliability. This category features two essential camshaft sprockets—the 55568386 Intake Sprocket and 55567048 Exhaust Sprocket—designed specifically for GM engines in motorcycles and powersports vehicles. These components are critical for maintaining accurate valve timing, preventing engine wear, and delivering smooth power transfer, making them a must-have for riders seeking OEM-grade performance without compromise.
Why GM Genuine Parts Sprockets Stand Out
GM Genuine Parts has built a stellar reputation as the gold standard for OEM components, offering unmatched quality that aftermarket alternatives often can't match. Crafted from high-strength materials, these sprockets resist wear from high-RPM operation and harsh riding conditions. Their exact-fit design ensures hassle-free installation, reducing downtime and boosting engine efficiency. Whether you're restoring a classic GM-powered powersports machine or upgrading for better performance, these sprockets provide the durability and precision that serious enthusiasts demand.
As part of our expansive Motorcycle & Powersports collection, GM Genuine Parts sprockets integrate seamlessly into broader maintenance routines, helping you keep your drive train in peak condition.
Key Features Buyers Should Consider
When shopping for sprockets, focus on these standout attributes of GM Genuine Parts offerings:
- Material Durability: Heat-treated steel construction withstands extreme temperatures and torque loads.
- Precision Tooth Profile: Engineered for flawless chain engagement, minimizing slippage and noise.
- OEM Specifications: Direct replacements that meet or exceed factory standards for compatibility.
- Corrosion Resistance: Protective coatings ideal for off-road or wet environments common in powersports.
These features make GM Genuine Parts sprockets ideal for high-mileage riders who prioritize longevity over cost-cutting alternatives.
Comparing GM Genuine Parts Camshaft Sprockets
Choosing between the 55568386 Camshaft Intake Sprocket and 55567048 Camshaft Exhaust Sprocket boils down to your engine's specific needs. The intake sprocket (55568386) drives the intake camshaft, optimizing air-fuel mixture delivery for better low-end torque and throttle response—perfect for trail bikes or cruisers needing responsive acceleration. In contrast, the exhaust sprocket (55567048) manages exhaust camshaft timing, enhancing scavenging and top-end power, which suits track-focused or high-speed powersports applications.
Both share GM's rigorous quality control, but pair them together for complete timing chain upgrades. If your vehicle shows signs of timing chain stretch or noisy operation, replacing both ensures synchronized performance. For broader options within Drive Train components, these fit perfectly alongside chains and tensioners.
Common Use Cases for GM Genuine Parts Sprockets
Riders turn to these sprockets for preventive maintenance during engine rebuilds, timing chain replacements, or performance tuning. They're especially valuable in GM-equipped ATVs, dirt bikes, or snowmobiles where precise camshaft synchronization prevents valve-piston interference and maximizes horsepower. Off-road enthusiasts appreciate their robustness against mud and debris, while street riders value the quiet, vibration-free operation.
If you're exploring alternatives, our Chains & Sprockets category offers complementary parts, and compare with brands like those in HP Sprockets for high-performance variants or Vortex Sprockets for lightweight racing options.
