Peterbilt 379 Torque Rods & U-Bolts

Aftermarket Torque Rods & U-Bolts are essential components for maintaining the performance and stability for your Peterbilt 379 truck. This product line includes a wide range of high-quality replacement parts, from torque rods and bushings to U-bolts and hardware, designed to keep your truck running efficiently. There are plenty of durable options from top brands like BESTfit, Reyco Granning, and more. With a focus on compatibility and easy installation, these essential aftermarket truck parts help ensure your truck's suspension system remains in optimal condition, reducing wear and tear and improving the overall ride quality. When you're overhauling your suspension system, it's also good to consider purchasing Peterbilt leaf spring hanger accessories (bushings and shackles) to enhance the fore-arm movement of your axle and achieve greater movement control during turns. Your Peterbilt 379 drive axle spring hangers are the foundation for your leaf springs that the U-bolts use to secure the axle. In short, without well-functioning hanger parts, your torque rods won't perform well either. You could also consider adding a set of replacement shock absorbers toreduce the stress on your U-bolts and lessen the strain on your torque rod mounting points. We have everything you need to properly maintain your truck's suspension system and ensure an amazing road performance for years to come.

Frequently Asked Questions About Peterbilt 379 Torque Rods & U-Bolts

Will these torque rods and U-bolts fit my specific year Peterbilt 379?

Most torque rods and U-bolts for the Peterbilt 379 are compatible with models from 1987-2007. However, there can be variations based on your suspension type (air ride vs. spring), axle configuration, and whether you have a short hood or long hood model. We recommend checking your current torque rod length and U-bolt dimensions before ordering. Torque rods typically come in standard lengths of 24", 26", 28", and 30". For U-bolts, measure the inside width and thread length to ensure proper fit.

What's the difference between OEM and aftermarket torque rods, and which should I choose?

OEM torque rods typically feature forged steel construction with factory-spec bushings that last 300,000-500,000 miles under normal conditions. Aftermarket options vary in quality - premium aftermarket brands use similar forged construction and high-grade rubber bushings, while economy options may use cast steel and lower-grade bushings that wear faster. For heavy-haul applications or if you want maximum longevity, stick with OEM or premium aftermarket. For lighter duty or budget-conscious repairs, quality aftermarket options can provide good value.

Can I replace torque rods and U-bolts myself, or do I need special tools?

Torque rod replacement requires basic hand tools plus a few specialized items: a large pry bar, torque wrench capable of 450-500 ft-lbs, and ideally a bushing press or large socket to install new bushings. The job typically takes 2-4 hours per axle. U-bolt replacement is more straightforward but requires proper torque specs (typically 450-500 ft-lbs) and should be done in a cross pattern. Always replace U-bolts in complete sets per axle. If you're not comfortable working with suspension components or don't have the proper tools, professional installation is recommended for safety.

How do I know when my torque rods and U-bolts need replacement?

Check torque rods for cracked or deteriorated bushings, which often show as black rubber chunks or tears. Worn torque rods cause driveline vibration, irregular tire wear, and wandering while driving. For U-bolts, look for stretched threads, corrosion, or any bending. Never reuse U-bolts after removal as they stretch during use. Industry standard is to inspect torque rods every 100,000 miles and replace U-bolts whenever you service spring packs or notice any deformation.

Do upgraded or heavy-duty torque rods make a difference for my application?

Heavy-duty torque rods with upgraded polyurethane or synthetic rubber bushings can significantly improve performance for specific applications. They reduce axle movement, improve handling, and last longer under extreme conditions. However, they also transmit more road vibration to the cab. For heavy-haul, off-road, or severe-duty applications, the trade-off is worthwhile. For highway driving or driver comfort priority, standard OEM-style rubber bushings provide the best ride quality. Match your components to your primary use case.
