1994-1996 Dodge Stealth Struts: Decoding ECS vs. Standard Suspension
This guide clarifies the critical differences between the standard passive suspension and the complex, failure-prone Electronic Control Suspension (ECS) to help you buy the right part.
- The most critical factor is identifying your suspension: standard passive or Electronically Controlled Suspension (ECS). 1994-95 R/T Twin Turbos have ECS; 1996 R/T Twin Turbos do not.
- A flashing 'TOUR/SPORT' light often points to a failed ECS computer module in the trunk due to leaking capacitors, not necessarily bad struts.
- When buying used ECS struts, the most important check is the electrical connector on top for corrosion or damage.
- You can replace failed ECS struts with more affordable passive struts, but you must unplug the ECS computer to turn off the dash warning light.
Vehicle Fitment: Standard vs. Electronic (ECS) Suspension
Before purchasing a replacement coil spring or strut, you must identify which suspension system your 1994-1996 Dodge Stealth is equipped with. Installing the wrong type will result in improper fitment, poor handling, and potential safety issues. The key difference is between the conventional passive suspension and the Electronically Controlled Suspension (ECS), which features struts with electric actuators on top.
Warning: The ECS system was discontinued for the final model year. A 1996 R/T Twin Turbo uses a different, non-electronic strut than a 1994-1995 model.
- Base & R/T (Front-Wheel Drive): These models typically came with standard, passive struts. The ride firmness is fixed. Some higher-trim FWD R/T models may have had the ECS as an option. Check for the 'TOUR/SPORT' switch near the shifter.
- R/T Twin Turbo (All-Wheel Drive) 1994-1995: These models came standard with the Electronically Controlled Suspension (ECS). These struts have a small electrical connector on the top of the center piston rod.
- R/T Twin Turbo (All-Wheel Drive) 1996: For the final year of production, Dodge removed the ECS system. These models use standard, passive gas-charged struts, similar to the base models but tuned for the AWD platform.
- Spyder Convertible (1995-1996): The rare Spyder models followed the same pattern. The FWD SL Spyder used passive struts, while the AWD VR-4 Spyder built in 1995 was equipped with the ECS system.
Symptoms of Failure
Failure symptoms differ significantly between the two suspension types.
Symptoms of Standard (Passive) Strut Failure
- Bouncy, Unstable Ride: The most common symptom. The car will continue to bounce up and down after hitting a bump.
- Nose-Diving and Squatting: The front of the car dips excessively during braking, or the rear squats during acceleration.
- Uneven Tire Wear: Look for a pattern of 'cupping' on your tires—a series of high and low spots—which indicates the tire is bouncing as it rolls down the road.
- Clunking or Knocking Noises: Worn internal components or failing strut mounts can cause noise when driving over bumps.
- Visible Fluid Leaks: Oily fluid leaking down the side of the strut body is a clear sign it has failed.
Symptoms of Electronic (ECS) Strut & System Failure
- Flashing 'TOUR/SPORT' Light: This is the most obvious sign of a problem. The ECS control unit detects a fault in the system and flashes the lights on the dashboard to alert the driver.
- System Stuck in 'SPORT' Mode: When a fault is detected, the system's default behavior is to lock the struts in the stiffest 'SPORT' setting. This results in a harsh, uncomfortable ride.
- Leaking ECS Control Module: The ECS computer, located in the trunk behind the passenger-side panel, is notorious for failing. Internal capacitors leak an oily, acidic fluid that corrodes the circuit board. This is a very common cause of the flashing light.
- No Change in Ride Quality: If pressing the 'TOUR/SPORT' button does not change the ride from soft to firm, the system is not working. This could be the struts, the switch, or the control module.
Pro Tip: If your ECS light is flashing, first check the ECS computer in the trunk for signs of leaking capacitors before assuming the struts themselves are bad. A repaired or replaced computer can often solve the problem.
Known Issues, Recalls, and TSBs
While there are no specific recalls for the struts or springs on the 1994-1996 Dodge Stealth, two safety recalls are relevant to the suspension and drivetrain systems:
- NHTSA Recall 02V143 (AWD Models): The all-wheel-drive transfer case can leak oil. If the oil level becomes too low, it can cause bearing damage and lead to a complete lockup of the drivetrain, increasing the risk of a crash.
- NHTSA Recall 96V201000 (1994 Models): Under conditions of full steering lock combined with suspension travel, the front brake hoses can crack and leak brake fluid. This can lead to a sudden loss of braking power.
Buying a Used Coil/Strut Assembly
A used OEM part is often the only cost-effective way to repair a failed ECS system. For standard suspension, it can be a good value alternative to new aftermarket parts. Here’s what to check.
Inspection Checklist for ANY Used Strut
- Check for Leaks: Inspect the main body of the strut. Any sign of oily residue indicates the internal seals have failed.
- Examine the Piston Rod: The shiny chrome rod extending from the top should be perfectly straight and free of rust, pitting, or damage. Nicks in the rod will tear the seals and cause leaks.
- Inspect the Spring: Look for heavy rust, cracks, or signs that the spring is sagging or broken.
- Check the Mounts: Ensure all mounting points, both at the top and the bottom, are straight and undamaged.
CRITICAL Checks for Used ECS Struts
- Inspect the Electrical Connector: The small, multi-pin connector on the very top of the piston rod is the most critical part. Look for bent or broken pins, corrosion, or cracks in the plastic housing. A damaged connector makes the strut useless for electronic control.
- Check the Wires: The wires leading from the connector into the strut top can become brittle and break. Gently check their condition.
- Ask About Functionality: Ask the seller if the strut was confirmed to be working before removal. Did the car it came from have flashing ECS lights?
Cost Comparison
Prices vary dramatically based on whether you need a standard passive strut or a hard-to-find electronic ECS strut.
| Part Type | Estimated Cost (Per Pair) | Notes |
|---|---|---|
| New OEM | $1000+ (if available) | New OEM ECS struts are exceptionally rare and expensive. Passive struts may still be available but are also costly. |
| New Aftermarket (Passive) | $150 - $400 | Readily available from brands like KYB for non-ECS cars. Full coilover conversion kits range from $250 to $1,200+. |
| Used OEM (Passive) | $75 - $200 | A good value option for standard suspension replacement. |
| Used OEM (ECS) | $200 - $500+ | The most common option for repairing an ECS system. Price depends heavily on condition and verified functionality. |
| Shop Labor (Pair) | $200 - $500 | Includes replacement and a required wheel alignment. |
Replacement Overview & Difficulty
- Difficulty Rating: 3 out of 5 (Moderate)
- Estimated Time: 2.5 - 4 hours for a pair.
- DIY Feasible: Yes, for experienced mechanics with the right tools.
Replacing a strut assembly requires lifting the vehicle, removing the wheel, and unbolting the strut from the steering knuckle at the bottom and the strut tower in the engine bay (front) or trunk (rear). The most dangerous part of the job is swapping the coil spring to the new strut, which requires a spring compressor tool. Failure to use this tool correctly can result in serious injury. For safety, buying a complete used assembly or a new 'quick-strut' (if available) that includes the spring is recommended.

Frequently Asked Questions (FAQ)
My 'TOUR/SPORT' light is flashing. Do I have to replace my struts?
Not necessarily. The flashing light indicates a fault anywhere in the ECS system. The most common failure point is actually the ECS control module in the trunk, which is known for leaking capacitors. Inspect the module for damage before buying expensive struts. The fault could also be a broken wire or a bad dash switch.
Can I replace my failed electronic struts with regular ones?
Yes, this is a very common and cost-effective modification. You can install standard passive struts or an aftermarket coilover system. However, to stop the 'TOUR/SPORT' light from flashing, you must unplug the ECS control module located behind the passenger-side trim panel in the trunk.
Why is a strut for a 1996 R/T Twin Turbo cheaper than for a 1995?
Because they are different parts. The 1995 R/T TT used the complex and expensive electronic ECS struts. For 1996, Dodge switched to a simpler, more reliable, and less expensive standard passive strut system.
Do I need to get a wheel alignment after replacing struts?
Yes, absolutely. The strut is a key component in setting alignment angles. Replacing one will alter the camber and toe settings. A four-wheel alignment is required after replacement to ensure proper handling and prevent rapid tire wear.
