Pacific Performance Engineering 158040300 Extreme-Duty Forged Idler Arm GM 2500HD 3500HD

The Pacific Performance Engineering (PPE) 158040300 Extreme-Duty Forged Idler Arm is a heavy-duty steering upgrade engineered to deliver superior strength and precision over the factory idler arm. Built from forged steel, this idler arm is purpose-designed for trucks running larger wheels and tires, elevated horsepower, or demanding use cases such as racing, sled-pulling, and off-roading.

Key Features:

• Forged steel construction — provides significantly increased strength and structural integrity over stamped or cast OEM components
• Dual spherical bearings — accommodates high radial loads for reliable, long-lasting steering performance
• 7/8-inch bolt assembly — eliminates angular misalignment and ensures precise steering control
• Replaceable dual bearings — designed for serviceability and extended service life
• Compatible with OEM center link — can be used with factory center link when the tapered perch is modified to accept the 7/8-inch bolt
