Will these fit any trim level of 2020 gladiator ? Or only specific models with certain axles?
These fit all Gladiator JT models. Thanks for your inquiry.
Is there already a factory front differential cover installed (on the Overland)? If so, how does this differ from what is already provided by the factory protection?
The covers that are sold on production axles are made of stamped steel, these are cast from nodular iron. The casting process can make more intricate designs like the facial ribs that provide greater strength and more sliding protection. OE covers can be bent and crushed on the trail which can ruin other internal components...more costly to fix. This cover made from iron, would crack under the same loads, saving the internals.
2019 JLUR -- what is the new capacity of the front and rear diff's with these new covers?
The capacities are unchanged with these new covers.
Two questions. Why does this cover have two fill holes? If I have a 2.5” lift which fill hole would I use? Also looks like it comes with RTV. The JL has a permanent gasket. I assume that can be used in place of the RTV? Thanks
The lower hole is for stock fluid capacity and the top hole is for increased fluid for heavy off-roading. You can reuse the original gasket if it is in good shape otherwise they provide RTV sealant.
Will these covers fit my 2020 Gladiator Sport?
Yes they fit the Sport rear axle on the Gladiator
Is this the correct cover for the 2020 Rubicon with a M220 rear axle? How about the same product for the Rubicon M210 front axle? Thanks
Yes the Rubicon axles that are used on the JL and JT are the Spicer Advantek, so this will fit. The 44 front axles require Spicer #10044799
Does this fit a 2020 Rubicon with the Dana M220 wide axle?
Yes the Rubicon axles are the Spicer Advantek for the JL and JT, so any accessory for that series will fit your application
'19 rubicon JL, is this fit rear axle? M220 same?
Yes this will fit the Rubicon rear axle
'19 rubicon JL, is this fit front axle? M210 same?
Yes this will fit the Rubicon front axle
Does this come with new bolts or am I reusing the bolts from the damaged factory cover? Does this come with a gasket?
This comes with new bolts and RTV sealant for the gasket. You can use a different gasket if you would like, but all parts are included for the initial installation.
