Dodge Ram 1500 (2009-2015) Alignment Specs

For service providers, the combination of different suspension components can make the alignment procedure challenging.

The Dodge Ram has been named as Motor Trend’s Truck of the Year a number of times.  The fourth generation of the truck featured a number of advancements and enhancements to keep it competitive in the marketplace. For service providers,  the combination of different suspension components can make the alignment procedure challenging.

Front Suspension Adjustments

The Ram 1500 comes with cam adjusters on the lower control arms at the subframe. If you need more camber or caster on a lifted or lowered truck, you can install an offset ball joint in the upper control arm. This modification can yield ±2.25 degrees of camber or caster. You should perform the final adjustments with the factory cams.


Moving the front or rear position of the lower control arm in or out will change the caster angle and camber angle significantly. To maintain the camber angle while adjusting caster, move one pivot bolt of the lower control arm in or out. Then move the other pivot bolt of the lower control arm in the opposite direction.

To increase positive caster angle, move the rear position of the lower control arm inward (toward the engine). Move the front of the lower control arm outward (away from the engine) slightly until the desired camber angle is obtained.


Move both pivot bolts of the lower control arm together in or out. This will change the camber angle significantly and have little effect on the caster angle. After the adjustment is made, tighten the lower control arm nuts to proper torque specification.

Rear Suspension

For 2009, Dodge introduced a multilink coil spring rear suspension. This live-axle setup weighs 40 pounds less than a leaf-spring configuration. Nothing is adjustable. 

For 2013, an air suspension system was an option. The system is tuned by a computer for optimal ride and aerodynamic performance. The system has a load-leveling capability, which detects if there is a trailer attached.

The air suspension system features five height settings that operate automatically or can be controlled manually using controls on the console. 

• Normal Ride Height (NRH): 220.9 mm (8.7 inches) of clearance (measured from the base of the door sill) is the default load-leveled ride height. This is the mode that should be active when performing an alignment.

• Aero Mode: Lowers the vehicle 27.9 mm (1.1 inches) from NRH. 

• Off-road 1: Lifts the vehicle 30.4 mm (1.2 inches) from NRH.

• Off-road 2: This mode increases ground clearance by 50.8 mm (2 inches over NRH).

• Park Mode: Lowers the vehicle 50.8 mm (2 inches) from NRH.


In 2012, Electric Power Steering (EPS) was made standard. The system provides variable assist for steering maneuvers using several sensor inputs. The Steering Angle Sensor (SAS) measures the position of the steering wheel and the rate of movement. The vehicle’s speed input comes from the anti-lock brake system. EPS steering gear has a torque sensor. 

The only serviceable parts are inner and outer tie rods and tie rod bellows.

The SAS is “self-calibrating” according to Chrysler. To reset the SAS, perform the following procedure:

1. Turn the ignition on and turn the steering wheel all the way to the left until lock is reached

2. Turn the steering wheel all the way to the right until full lock is reached

3. Return the steering wheel to center

4. Cycle the ignition

Even after this procedure is performed, the ESP light might still be on. Go for a short test drive to allow the system to use the yaw and lateral accelerometers to carry out the final calibrations. 

The other option is to use a scan tool to verify the readings from the SAS and clear the codes in the 2009-2015 Dodge Ram.

How To Answer Customer Ride Control Questions

Presenting your customer with inspection results and benefits of replacement will help sell the job.

Your typical customer is not like you; their point of view is completely different. You must understand what they know and what they value when it comes to their transportation. The old proverb “walk a mile in their shoes” applies to advising customers about shocks and struts.

Selling ride control is difficult. If you just sell them shocks and struts, you are asking the customer to exchange money for a parts and service. Advising and educating a customer about the condition of their car or truck is easy. Presenting your customer with inspection results and benefits of replacement will sell the job without even asking for the sale.
