Frequently Asked Questions
What is the YP C5-GM8.5?The YP C5-GM8.5 is a steel replacement differential cover for GM 8.2, 8.5, and 8.6 inch rear axles that bolts on in place of a damaged or leaking factory cover.
Does this cover include the bolts?The kit includes the cover, fill plug, and gasket. Reusing your factory cover bolts is recommended if they are in good condition.
Will this fit my 2002 Trailblazer or Envoy?No, this cover is not designed for 2002 to 2009 Envoy and Trailblazer models, which use a different housing.
Do I need a new gasket every time I remove the cover?Yes, replacing the gasket whenever the cover is removed helps ensure a proper leak-free seal.
Does installing this cover require draining the differential fluid?Yes, you will need to drain the gear oil before removing the old cover and again refill it once the new cover is installed.
Is this cover compatible with aftermarket ring and pinion gears?Yes, since it is a direct bolt-on replacement for the factory cover, it works with stock or upgraded ring and pinion setups inside the same housing.
What tools do I need to swap this cover?A basic socket set and a gasket scraper are typically all that is needed for this installation.
Does this cover come pre-painted or coated?It ships as bare stamped steel, so many customers choose to paint or coat it before or after installation to match their vehicle.
