2018 Jeep Rubicon Suspension Part Numbers: Complete OEM Reference

If you own a 2018 Jeep Wrangler Rubicon, knowing the exact OEM suspension part numbers is essential for accurate replacements or upgrades. The JL-generation Rubicon came with a unique suspension setup that differs from other trims, including specific shocks, springs, and bars. Whether you’re repairing from a trail mishap or planning a lift kit, using the correct factory part numbers ensures proper fit and performance. This guide lists the most common OEM MOPAR suspension part numbers for the 2018 Rubicon, organized by front and rear components.

Front Suspension Part Numbers

The front suspension on the 2018 Rubicon includes heavy-duty shocks, progressive-rate springs, a sway bar, track bar, and control arms. Below are the numbers for the standard 3.6L Pentastar V6 and 2.0L turbo models. Note that part numbers can vary based on engine, transmission, or optional equipment like the tow package. Always verify with your VIN before ordering.

Front Shocks

• Front Shock (Right): MOPAR 68244070AB
• Front Shock (Left): MOPAR 68244071AB These shocks are the factory Fox shocks (on Rubicon with optional upgraded shocks) or standard gas-charged units. If your Rubicon has the upgraded Fox shocks, the numbers above apply. Otherwise, standard shocks are 68244068AB (right) and 68244069AB (left). Check your build sheet.

Front Springs

• Front Spring (Right): MOPAR 68314222AA (standard ride height)
• Front Spring (Left): MOPAR 68314223AA (standard ride height) For Rubicons with the optional tow package or diesel engine, spring rates differ. Those springs are 68314224AA (right) and 68314225AA (left). Always cross-reference with your GVWR and engine type.

Front Sway Bar

• Front Sway Bar: MOPAR 68315780AB
• Sway Bar Link (each): MOPAR 68312970AA The Rubicon uses a front sway bar with a disconnect mechanism. The main bar assembly includes the actuator. The links are the same for all JL models.

Front Track Bar

• Front Track Bar: MOPAR 68306942AA This bar connects the front axle to the frame. It is unique to the Rubicon due to the wider Dana 44 axle. The ball joint end is replaceable separately.

Front Control Arms

• Front Upper Control Arm: MOPAR 68321712AB (right), 68321713AB (left)
• Front Lower Control Arm: MOPAR 68321714AB (right), 68321715AB (left) Control arm part numbers are the same across most JL models, but Rubicon-specific arms have a forged steel construction for strength. Bushings can be purchased separately (MOPAR 68326983AA for lower, 68326984AA for upper).

Rear Suspension Part Numbers

The rear suspension of the 2018 Rubicon is designed for off-road articulation. Components include shocks, springs, sway bar, track bar, and control arms.

Rear Shocks

• Rear Shock (Right): MOPAR 68244072AB
• Rear Shock (Left): MOPAR 68244073AB These match the front shock options. If your Rubicon has adaptive damping, use 68244074AB (right) and 68244075AB (left). Standard shocks are 68244076AB and 68244077AB.

Rear Springs

• Rear Spring: MOPAR 68314226AA (standard)
• Optional Heavy-Duty Rear Spring: MOPAR 68314227AA (for tow package or diesel) Rear springs are the same on both sides. The standard spring rate is about 140 lbs/in; heavy-duty is 160 lbs/in.

Rear Sway Bar

• Rear Sway Bar: MOPAR 68315781AB
• Rear Sway Bar Links: MOPAR 68312971AA (each) The rear sway bar is thinner than the front. Links are the same as front, but the part number is different for the rear position.

Rear Track Bar

• Rear Track Bar: MOPAR 68306943AA Like the front, the rear track bar centers the axle. It uses a forged bracket and ball joint. Replacement ball joint: MOPAR 68326985AA.

Rear Control Arms

• Rear Upper Control Arm: MOPAR 68321716AB (right), 68321717AB (left)
• Rear Lower Control Arm: MOPAR 68321718AB (right), 68321719AB (left) Rear control arms are generally interchangeable with front, but the left and right are specific due to parking brake cable brackets.

Other Suspension Components

Beyond the main parts, these numbers help for complete overhauls:

• Front Bump Stop: MOPAR 68303678AA
• Rear Bump Stop: MOPAR 68303679AA

• Spring Isolator (lower) : MOPAR 68314229AA (per spring)

Using Part Numbers for Replacements

OEM part numbers ensure you get the exact component designed for your 2018 Rubicon. When ordering from a dealer or online MOPAR retailer, provide the number and your VIN. Some parts, like shocks and springs, may be superseded (e.g., AB to AC revision). Always confirm current revision at time of order.

For aftermarket suspensions, OEM numbers help compare dimensions and mount styles. Many aftermarket shocks require the factory dust boot or bracket; knowing the OEM number allows you to reuse parts.

Final Recommendation

Keep this list handy as a reference, but always verify part availability and compatibility with your specific Jeep. The easiest way is to call a Jeep dealership parts department with your VIN—they can look up the exact part numbers for your build. If you’re replacing suspension for a lift kit, many manufacturers include all necessary brackets, but you may still need OEM track bar or sway bar links. For a stock replacement, stick with MOPAR numbers to preserve ride quality and warranty compliance. Having these numbers saves time and prevents errors.
