If it refers to the 3.0L EcoDiesel V6, specifications for its turbocharging, common rail injection, and emissions control would be crucial. If it's another engine, detailed specifications would be required. Performance Horsepower Torque 3.6L: Typically around 285 hp and 260 lb-ft of torque (exact figures depend on specific tuning for the year). Horsepower Torque 2.8L Diesel: Varies by market and tune, but generally in the 170-200 hp range and 300-350 lb-ft of torque. Fuel System Fuel Type: Petrol (for 3.6L V6), Diesel (for 2.8L Diesel) Injection Type: Multi-port Fuel Injection (MPI) for 3.6L, Common Rail Direct Injection (CRDI) for 2.8L Diesel. Maintenance Components Timing Belt Chain: 3.6L Pentastar uses a timing chain; 2.8L Diesel uses a timing chain or belt depending on specific design, but chains are more common for longevity. 🔧 Transmission Standard Transmission Types: Available with both manual and automatic transmissions. Optional Manual Transmission: Likely a 6-speed manual gearbox. Automatic Transmission: Likely a 5-speed or 6-speed automatic transmission. Features Transfer Case: Command-Trac (NV241GII) or optional Rock-Trac (NV241OR) for enhanced off-road capability, offering 2WD High, 4WD High, Neutral, and 4WD Low ranges. Maintenance Transmission Fluid Specs Auto: Specific ATF (Automatic Transmission Fluid) type, likely a Mopar or equivalent spec fluid. Transfer Case Fluid Specs: Specific transfer case fluid type, likely a Mopar or equivalent spec fluid. 📐 Dimensions Exterior Wheelbase 2 Door: Approx. 95.4 inches (2423 mm) Wheelbase 4 Door Jku: Approx. 116 inches (2946 mm) Ground Clearance: Varies by trim and tire size, but generally excellent for off-road use (e.g., over 10 inches for Rubicon models). Weights Curb Weight: Varies significantly by configuration (2-door vs. 4-door, engine, transmission, options), typically ranging from 4,000 to 4,500 lbs. 🛡️ Safety Features Ratings NHTSA Ratings: Frontal crash test ratings were typically good, but side impact and rollover ratings could vary. The JK generation's design, especially with solid axles, may have specific considerations. Active Features ABS: Standard Anti-lock Braking System (ABS) Traction Control: Electronic Stability Control (ESC) with traction control and trailer sway control. Hill Start Assist: Likely included on...
