2004-2014 F150 Belltech 1 Degree Pinion Shim Kit 4973

Adjusts Pinion Angle for Proper Driveline Performance and Longevity

Whenever you lower the rear end of your truck, you throw off your 2004 to 2014 F150's pinion angle to some degree. If you lower your rear end far enough, the change in pinion angle can become problematic and cause excess NVH and shorter lifespan of your F150's driveline. Belltech's 1 Pinion Angle Shim Kit adjusts your truck's pinion angle by one full degree after your slight rear suspension drop, which helps you get your truck's driveline back into OEM specs. Belltech's kit fits F150s with OEM or OE-style 2.5" to 3" wide leaf springs and comes with everything you need to get them installed.
