SuperPro 2011+ Dodge Durango Heat Front 34mm Sway Bar Mount Bushing Set

Precision-Engineered Polyurethane Sway Bar Bushing for the Dodge Durango and Jeep Grand Cherokee

The SuperPro SPF4764-34K is a front sway bar mount bushing set engineered specifically for the 2011-2021 Dodge Durango and 2011-2021 Jeep Grand Cherokee. Designed to replace the 34mm factory rubber bushing, the SPF4764-34K uses SuperPro's proprietary polyurethane compound to restore and improve the connection between the front sway bar and chassis. Worn or degraded OEM rubber bushings allow unwanted sway bar movement in multiple planes, undermining the sway bar's ability to control body roll. Upgrading to the SPF4764-34K recalibrates that connection, resulting in tighter cornering response, reduced body roll, and improved overall handling confidence whether you are driving daily or pushing the Durango or Grand Cherokee harder on winding roads.

Key Features

• Polyurethane Construction: SuperPro's proprietary polyurethane formula resists compression set, cracking, and chemical degradation far longer than OEM rubber, extending service life even under harsh conditions.
• Grease-Retaining Design: The SPF4764-34K incorporates internal lubrication channels that hold grease at the contact interface, preventing squeak and wear throughout the life of the bushing.
• OEM-Accurate 34mm Bore: Machined to match the factory 34mm sway bar diameter exactly, ensuring a secure, rattle-free mount with no shimming or modification required.
• Sold as a Complete Set: Each kit includes both driver-side and passenger-side bushings along with retaining clamps, so the full front mount position is addressed in a single purchase.
• No Alignment Required After Install: Replacing the sway bar mount bushings does not affect wheel alignment angles, so you can complete the job and drive immediately without a trip to an alignment shop.
• Beginner-Friendly Installation: The job rates as easy difficulty and can be completed by a home mechanic with basic hand tools in approximately 30 to 45 minutes per side using a standard floor jack and jackstands.
• Lifetime Warranty: SuperPro backs the SPF4764-34K with a lifetime warranty against manufacturing defects when installed and maintained per the supplied instructions.

Frequently Asked Questions

What vehicles does the SPF4764-34K fit?
The SPF4764-34K is designed for 2011-2021 Dodge Durango and 2011-2021 Jeep Grand Cherokee models equipped with a 34mm front sway bar. Refer to the fitment table above to confirm your specific trim year combination before ordering.

What is the difference between the SPF4764-34K and the SPF4764-33K?
The only difference is the sway bar diameter they are designed for. The SPF4764-34K fits a 34mm sway bar, while the SPF4764-33K fits a 33mm sway bar. Check the diameter of your factory sway bar before ordering to ensure the correct fitment. Some Durango and Grand Cherokee trims were equipped with different diameter bars across model years.

Will installing the SPF4764-34K require a wheel alignment?
No. Sway bar mount bushings are chassis-to-sway-bar interface components and do not affect any of the alignment parameters (toe, camber, or caster). You can install the SPF4764-34K and drive the vehicle immediately without a visit to an alignment shop.

How does polyurethane compare to the OEM rubber bushing it replaces?
OEM rubber bushings are designed for ride comfort above all else and soften over time, allowing sway bar movement in multiple directions. SuperPro's polyurethane compound used in the SPF4764-34K holds its durometer far longer, resists oil, ozone, and UV degradation, and provides a firmer, more consistent interface that keeps the sway bar working at peak efficiency. The trade-off is a marginally firmer feel, which most drivers consider a worthwhile exchange for improved handling response.

Will the SPF4764-34K cause squeaking?
No, as long as the bushings are properly lubricated at installation using the included grease. SuperPro's internal grease-channel design retains lubricant at the contact surface for the life of the bushing. Never use petroleum-based grease on polyurethane; always use the supplied SuperPro grease or a compatible silicone-based grease.

Does the SPF4764-34K come with a warranty?
Yes. SuperPro backs the SPF4764-34K with a lifetime warranty against defects in materials and workmanship. This warranty applies when the bushing is installed and maintained according to the included instructions. Note that this warranty covers the part itself and does not extend to labor or consequential damages. Per the Magnuson-Moss Warranty Act, this warranty does not void your vehicle's factory warranty as long as the installation does not cause the underlying factory defect being claimed.

How difficult is it to install the SPF4764-34K at home?
This is considered an easy to intermediate job for a home mechanic. You need a floor jack, jackstands, basic hand tools, and the included grease. Total time is approximately 30 to 45 minutes per side. No press, specialty tools, or heat is required. The full 12-step process is outlined in the installation instructions section below.

Can I install only one side, or do both sides need to be replaced at the same time?
It is strongly recommended to replace both sides at the same time. Replacing only one side creates an imbalance in the sway bar system. Since the SPF4764-34K is sold as a complete two-bushing set, both sides are included in the kit.

Will the SPF4764-34K fit Jeep Grand Cherokee WK2 SRT and Trackhawk trims?
The SPF4764-34K fits 2018-2021 Jeep Grand Cherokee SRT trims as shown in the fitment table. Always confirm your vehicle's front sway bar diameter is 34mm before ordering, as performance trims can sometimes use a larger bar that requires a different size bushing.

Does this bushing fit the Dodge Durango SRT Hellcat?
Yes. The 2021 Dodge Durango SRT Hellcat is included in the fitment table for the SPF4764-34K. Verify bar diameter at 34mm before ordering.

Installation Instructions

1. Park the vehicle on a flat, level surface. Engage the parking brake and place wheel chocks behind the rear tires.
2. Loosen the front lug nuts slightly before lifting the vehicle. Raise the front of the vehicle with a floor jack placed under the designated lift points, then secure it on jackstands rated for the vehicle's weight.
3. Remove the front wheels to gain clear access to the front sway bar and its chassis mount brackets.
4. Inspect the sway bar end links. If they are worn or damaged, this is an ideal time to replace them before reinstalling the sway bar system.
5. Locate the two sway bar mount brackets on the front subframe. Each bracket is secured by two bolts. Using the appropriate socket, remove all four bolts (two per bracket) and set them aside.
6. Remove both metal retaining brackets and set them aside. Take note of the orientation of the brackets relative to the sway bar before removal.
7. Slide the old rubber OEM bushings off the sway bar. If they have hardened or bonded to the bar, use a plastic trim tool to carefully work them free without scratching the bar surface.
8. Clean the sway bar mounting surfaces with a clean rag to remove any old grease, debris, or corrosion.
9. Apply the supplied SuperPro grease (or a compatible silicone-based grease) generously inside the bore of each new SPF4764-34K polyurethane bushing and around the outside of the sway bar at the mount locations. Do not use petroleum-based grease.
10. Slide each SPF4764-34K bushing onto the sway bar at the correct mount location. Ensure the split in the bushing faces downward and is oriented per the instruction sheet included in the kit.
11. Position the retaining brackets over the bushings, ensuring the flat face of the bracket seats flush against the flat face of the bushing. Thread in the bracket bolts by hand first to confirm correct alignment.
12. Torque the sway bar bracket bolts to the vehicle manufacturer's specified torque value (refer to a factory service manual for your specific model year). Do not over-torque, as this can distort the bushing bore.
13. Reinstall the front wheels and hand-tighten the lug nuts.
14. Raise the vehicle off the jackstands, remove the stands, and lower the vehicle to the ground. Torque the lug nuts to the manufacturer's specification in a star pattern.
15. Start the vehicle and turn the steering wheel lock-to-lock several times to allow the bushings to settle into position. Inspect all hardware for any signs of movement or unusual noise before driving.
