PCP lets you build your Chrome Differential Cover here on our site; choose the color, fasteners, drain and/or fill plug and gasket type.


*Powder Coating - Over 32 different colors to choose from, from clear to textures and everything in-between.
If you order only one option we suggest ordering the clear powder, this will increase the durability and life of
your chrome cover exponentially and it does not dull the chrome shine whatsoever.

* Drain Plug - Differential covers from the factory do not have drain plugs in them, for this reason we offer this
option. Automakers suggest changing you gear lubricant once every 15,000 miles (about a year of driving).
The only way to drain your lubricant without this option is to remove the complete cover and let drain, scrape
and replace gasket and reinstall new gasket, install and torque all fasteners. With a drain plug in place you
remove one (1) bolt let drain and replace that one bolt…hands do not even get dirty.

* Fill Plug - Some factories do have fill plugs in the differential covers, if yours does not order this option to make
maintenance easy. Taking into consideration all the fluids used in a vehicle the axles are the least maintained.

* Magnetic Fill Plug - This will trap the small metal particles that could potentially damage and prematurely wear
the differential components. When changing your gear lube simple clean the magnet off before reinstalling.

*Fasteners - From economy conscious Zinc Plated Hex Nuts to corrosion resistant Stainless Steel Socket Head
Cap Screws. Stainless Steel will not rust or discolor, the same grade that is used in the food industry.
We have everything in-between.

*Gasket - Let's face it some of us do not like gaskets on our oil pans, valve covers or your differential covers, etc.
And yet others swear by them (the auto factories do). Other will only use RTV (Room Temperature Vulcanizing
elastomer sealant). Rather than include and charge you for a gasket that may never be used we leave the decision to you.

* PCP Logo - Our PCP Logo Skull will be powder coated onto your chrome cover free of charge. And if its powder
coated onto the cover it won't be going anywhere…it's there to stay.
