Unleashing the Beast: A Comprehensive Guide to 2012 Jeep Grand Cherokee SRT8 Parts
Before diving into specific parts, it's vital to understand the key systems of your 2012 SRT8. The 6.4L HEMI V8 is the heart, producing 470 horsepower and 465 lb-ft of torque. This power is transferred through a five-speed automatic transmission to a full-time four-wheel-drive system. The SRT8 also features performance-tuned suspension, Brembo brakes, and a distinctive aerodynamic body kit. Knowing the purpose and function of these systems will help you identify the right parts for your specific needs.
2. Essential Maintenance Parts: Keeping the Beast Alive
Like any high-performance vehicle, the 2012 Grand Cherokee SRT8 requires regular maintenance to ensure reliability and longevity. Here are some essential maintenance parts you should consider:
- Engine Oil and Filter: Regular oil changes are critical. Use a high-quality synthetic oil that meets Chrysler's specifications (typically 0W-40) and a Mopar or equivalent oil filter.
- Air Filter: A clean air filter ensures optimal airflow to the engine. Consider a performance air filter for increased airflow and potentially a slight power boost.
- Spark Plugs: Replace spark plugs according to the manufacturer's recommended interval. Using the correct type of spark plug is crucial for proper engine operation.
- Brake Pads and Rotors: The Brembo brakes are a vital part of the SRT8's performance. Regularly inspect brake pads and rotors for wear and replace them when necessary. Use high-quality brake pads designed for performance applications.
- Fluids: Regularly check and replace fluids such as coolant, transmission fluid, power steering fluid, and brake fluid. Use fluids that meet Chrysler's specifications.
- Belts and Hoses: Inspect belts and hoses for cracks or wear and replace them as needed to prevent unexpected breakdowns.
- Battery: A strong battery is essential for starting the powerful engine. Consider an AGM battery for improved performance and longevity.
3. Performance Upgrades: Unleashing the Full Potential
For those seeking to extract even more performance from their 2012 SRT8, a wide range of aftermarket performance parts are available. Here are some popular upgrade options:
- Cold Air Intake: A cold air intake replaces the factory airbox with a more efficient design that allows for greater airflow to the engine. This can result in a noticeable increase in horsepower and torque.
- Exhaust System: Upgrading the exhaust system can improve exhaust flow, resulting in increased horsepower and a more aggressive sound. Options range from cat-back systems to full exhaust systems with headers.
- Tuning: A custom tune can optimize the engine's performance by adjusting parameters such as fuel injection, ignition timing, and throttle response. A professional tuner can tailor the tune to your specific modifications and driving style.
- Supercharger: For those seeking serious power gains, a supercharger kit can dramatically increase horsepower and torque. Supercharger kits are a significant investment but can transform the SRT8 into a true performance monster.
- Suspension Upgrades: Upgrading the suspension can improve handling and reduce body roll. Options include lowering springs, adjustable coilovers, and upgraded sway bars.
- Brake Upgrades: While the Brembo brakes are excellent, some owners opt for even larger rotors and calipers for improved stopping power, especially for track use.
- Wheels and Tires: Upgrading to lighter and wider wheels and tires can improve handling, acceleration, and braking.
4. Body and Exterior Parts: Aesthetics and Functionality
Beyond performance, many owners also customize the appearance of their SRT8. Here are some common body and exterior part upgrades:
- Front Lip Spoiler: Adds a more aggressive look to the front of the vehicle and can improve aerodynamics.

- Lighting: Upgrading to LED headlights, taillights, and fog lights can improve visibility and add a modern touch.
- Grille: Replacing the factory grille with an aftermarket grille can change the overall look of the front of the vehicle.
