Axle Lubricant and Trailer Towing
1500 Models
• 1500 Model rear axles are trailer tow ready. Limited
slip rear axles on 1500 models require the use of a
limited slip additive (refer to the “Recommended
Fluids, Lubricants, and Genuine Parts” section.)
• The limited slip additive is included with the factory
fill.
• If the axle fluid is changed, 4 oz. (118 ml) of limited slip
additive must be added.
2500/3500 Models
• The Axles on 2500/3500 Models are trailer tow ready
and DO NOT REQUIRE any special axle lubes or
additives.
Trailer Towing Recommendations
• All trailer hitches should be professionally installed on
your vehicle.
• Safety chains must always be used between your
vehicle and trailer.
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury. An electrically–actuated electric trailer
brake controller is recommended.
• Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of
2,000 lbs (907 kg)
• Use an approved wiring harness connector on the
trailer. Standard equipment on all RAM pickup mod-
els provides a 4-way trailer tow connector located
