Wheelbase Options:
Varies by cab and bed configuration (e.g., 120.5" for Regular Cab Short Bed, 140.5" for Quad Cab Short Bed, 160.5" for Crew Cab Long Bed).
Overall Length Approx:
200-240 inches (approx., depending on configuration)
Curb Weight Approx:
4,500 - 5,500 lbs (approx., depending on configuration and engine)
Bed Length Options:
6'4" (Short Bed), 8'0" (Long Bed)
Engine Oil Change Interval:
Typically every 3,000-7,500 miles or 6 months, depending on oil type and driving conditions (refer to manual for specific recommendation based on oil used).
Transmission Fluid Change Interval:
Every 30,000-60,000 miles for automatic transmissions, depending on use and fluid type. Manual transmissions generally require less frequent service.
Coolant Change Interval:
Typically every 30,000-60,000 miles or 3-5 years for HOAT coolant.
Engine Oil Specification:
Refer to owner's manual, typically SAE 5W-20 or 5W-30 for 3.7L V6 and 4.7L V8, and 5W-20 for 5.7L HEMI. Always verify with the manual or oil cap.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid.
Power Steering Fluid:
Mopar Power Steering Fluid or equivalent.
Heatexchanger Leaks:
Some reports of heater core leaks, particularly with the 5.7L HEMI engine, can lead to coolant loss and cabin fogging.
Throttle Body Issues:
Occasional issues with electronic throttle bodies causing rough idle or stalling.
Transmission Hard Shifting:
Some 45RFE/545RFE transmissions may exhibit hard shifting or occasional flare between gears, often related to solenoid pack or valve body issues.
Heritage:
Dodge has a long history of producing robust and capable trucks, with the Ram line evolving significantly since its inception in 1981.
Generation:
This 2008 model is part of the fourth generation of Dodge Ram trucks (2009-2018 model years, with 2009 marking a major redesign; 2008 is the final year of the third generation, DS/DJ platform).
