Energy Suspension Stabilizer Bar Bushing Kit Part 5.5126G: What You Need to Know

The Energy Suspension stabilizer bar bushing kit part 5.5126G is a replacement bushing set designed for the front stabilizer bar on select vehicles. This kit includes premium polyurethane bushings and the necessary hardware to restore or upgrade the sway bar connection. Over time, original rubber bushings dry out, crack, and lose their ability to control chassis roll. Replacing them with polyurethane units can tighten handling, reduce body lean in corners, and extend the life of the stabilizer bar system. This article covers everything you need to know about the 5.5126G kit—from applications and features to installation tips and why it matters for your vehicle.

Overview of the Energy Suspension 5.5126G Kit

This bushing kit is specifically engineered to fit the front stabilizer bar on popular trucks and SUVs. Part number 5.5126G refers to a set of two polyurethane bushings and the required metal sleeves or brackets. The bushings are formulated from Energy Suspension’s proprietary Hyper-Flex™ material, which offers superior durability and resistance to weather, oil, and road contaminants compared to standard rubber.

Features and Benefits

• Polyurethane Construction: Unlike OEM rubber, polyurethane does not compress as much under load. This results in firmer, more responsive sway bar action.
• Corrosion-Resistant Hardware: The kit includes zinc-plated brackets and hardware to prevent rust and ensure a secure fit.
• Precision Fit: Each bushing is molded to exact specifications for the specific application, reducing the chance of misalignment.
• Improved Handling: By eliminating slack in the sway bar bushings, the kit reduces body roll during cornering and lane changes.
• Longevity: Polyurethane outlasts rubber by several times, especially in harsh climates.

Vehicle Applications for Part 5.5126G

This kit is designed for the front stabilizer bar on certain GM trucks and SUVs. The primary applications include:

• Chevrolet Silverado 1500 (2007-2014)
• GMC Sierra 1500 (2007-2014)
• Chevrolet Suburban 1500 (2007-2014)
• GMC Yukon/Yukon XL (2007-2014)
• Cadillac Escalade (2007-2014)

It also fits some earlier models with the same stabilizer bar diameter. Always verify your vehicle’s stabilizer bar diameter before purchasing. The 5.5126G is intended for a 32mm front sway bar on these applications.

Compatible Models Checklist

Before buying, confirm the following:

• Vehicle year and model fall within the listed range.
• Front stabilizer bar diameter measures exactly 32mm (measure at the bushing location).
• Your current bushings are the rubber, clevis-style design (two-piece with a bracket).

Installation Guide for the Energy Suspension Bushing Kit

Replacing stabilizer bar bushings is a moderate DIY job. With basic tools, you can complete the installation in under two hours. Here’s what you need and the general steps.

Tools Needed

• Jack and jack stands (or ramps)
• Socket set (metric and SAE)
• Torque wrench
• Pry bar or flathead screwdriver
• Wire brush or sandpaper
• Silicone grease (recommended for polyurethane bushings)

Step-by-Step Process

1. Safety First: Raise the vehicle and secure it on jack stands. Remove the front wheels for better access.
2. Locate the Stabilizer Bar Bushings: The front sway bar bushings are mounted to the frame or lower control arms, usually two per side.
3. Remove Old Bushings: Unbolt the bracket holding each bushing. If rubber is stuck, use a pry bar to work it off. Clean the sway bar with a wire brush to remove rust and debris.
4. Prepare New Bushings: Apply a thin layer of silicone grease to the inside of each polyurethane bushing. This prevents squeaking and helps the bushing slide onto the bar.
5. Install New Bushings: Position the bushing around the sway bar, ensuring the split faces outward. Place the bracket over the bushing and hand-tighten the bolts.
6. Torque to Spec: Using a torque wrench, tighten the bracket bolts to the manufacturer’s specification (typically 30-40 ft-lbs for these applications). Over-tightening can damage the bushing.
7. Reinstall Wheels and Lower Vehicle: After both sides are done, reinstall the wheels, torque the lug nuts, and lower the vehicle.
8. Test Drive: Take a short test drive to feel the difference. Expect reduced body roll and more direct steering response.

Tip: If your stabilizer bar links are also worn, consider replacing them at the same time for maximum improvement.

Why Choose Energy Suspension Bushings?

Energy Suspension has been a leading manufacturer of polyurethane suspension components since the 1980s. Their parts are known for:

• Quality Control: All bushings are made in the USA from US-sourced materials.
• Performance Focus: Polyurethane provides a balance between comfort and control, making it suitable for daily drivers and light trucks.
• Warranty: Energy Suspension offers a limited lifetime warranty against defects.

Other bushing materials like rubber degrade faster, while harder polyurethane options can transmit more vibration. The 5.5126G uses a medium-durometer formulation that minimizes NVH (noise, vibration, harshness) while still improving stability.

Final Recommendation

If you own a 2007-2014 GM full-size truck or SUV with a 32mm front sway bar, the Energy Suspension stabilizer bar bushing kit part 5.5126G is an excellent upgrade. It directly replaces worn rubber bushings, restores sway bar function, and enhances handling without breaking the bank. Installation is straightforward for any intermediate DIYer, and the polyurethane construction will last years longer than stock rubber. For best results, pair this kit with new stabilizer bar end links and ensure all bolts are torqued properly. Whether you're towing, hauling, or just want sharper cornering, this bushing kit is a practical, high-value improvement.
