Frequently Asked Questions About Kenworth T600 Torque Rods & U-Bolts

What are the most common sizes for T600 torque rods, and how do I know which length I need?

Kenworth T600 torque rods typically come in lengths ranging from 23 inches to 30 inches, with the most common being 25-inch and 28-inch variants. To determine your exact length, measure from the center of one bushing to the center of the other bushing on your existing torque rod. Keep in mind that different suspension configurations (air ride vs. spring) may require different lengths. If you're unsure, check your truck's build sheet or contact us with your VIN for verification.

Are aftermarket torque rods and U-bolts as durable as OEM parts for my T600?

Quality aftermarket torque rods and U-bolts can match or exceed OEM specifications when sourced from reputable manufacturers. Look for parts made from forged steel rather than cast iron, with Grade 8 U-bolts that meet SAE J429 standards. Premium aftermarket options often feature improved bushing materials like polyurethane or heavy-duty rubber compounds that last longer than standard OEM bushings, especially in severe-duty applications.

Can I install torque rods and U-bolts myself, or should I have a shop do it?

While torque rod replacement is possible for experienced DIY mechanics, it requires proper jack stands, torque specifications, and alignment afterward. U-bolt installation is more straightforward but requires a torque wrench capable of 250-450 ft-lbs depending on your axle rating. Critical factors include torquing U-bolts in a cross pattern to specification and ensuring proper torque rod angle (typically 0-5 degrees down angle). Improper installation can cause premature wear, vibration, or suspension damage.

What year range compatibility should I look for when ordering T600 parts?

Kenworth T600 trucks manufactured from 1985 to 2007 generally share similar suspension designs, but there are important variations. Pre-1995 models may have different bushing sizes and torque rod lengths compared to 1995-2007 models. Additionally, verify whether you have Hendrickson, Reyco, or Kenworth AG suspension systems, as each requires specific torque rod configurations. Always cross-reference part numbers with your specific year and suspension type.

How often should torque rods and U-bolts be inspected or replaced?

Inspect torque rods every 50,000 miles or during regular PM services. Look for bushing cracks, excessive play, or bent rods. U-bolts should be checked for stretching, corrosion, or loose nuts every 25,000 miles. Replace torque rods when bushings show separation, excessive movement (more than 1/8 inch play), or visible damage. U-bolts typically need replacement if they've been loosened more than twice, show thread damage, or exhibit any stretching beyond original length.
