Product Description

The Carli CS-FPSKIT-3X2 2° Pinion Shim Kit is a precision drivetrain geometry component designed for lifted Ford F-250 and F-350 4WD trucks from 2005 through 2024. As suspension lifts alter rear pinion angles, driveline vibration and noise can become noticeable - especially around highway speeds. This kit corrects that by introducing a precise 2-degree shim between the rear leaf springs and axle perch, optimizing the pinion angle and improving smoothness under power. This driveline alignment improves overall road manners and reduces common vibration complaints without the need for guesswork or repeated adjustments.

Built with high-strength shim plates and new center pin hardware, the CS-FPSKIT-3X2 installs in place of the factory center pin and is engineered for use on trucks equipped with lifted or leveled suspension systems. Its direct bolt-in design makes for straightforward installation when servicing the rear suspension or performing upgrades, and it supports both gas and diesel Ford Super Duty models throughout the covered year range. Whether your build focuses on towing, daily driving, or off-road capability, correcting the pinion angle with this shim kit helps ensure a smoother and more reliable driveline experience.
