14 Bolt 3/8" Differential Cover

14 Bolt 3/8" Differential Cover

Part Number: OP14COV
  • Ring and Cover are 3/8" thick
  • Plate steel CNC bent 8 ways
  • Machined absolutely flat for a perfect fit
  • All seams welded inside and out

Note: Our world famous beefy 3/8" thick differential cover fit's the full float 14 Bolt axles and will mate up fine with your ribbed 14 bolt axle. However, the additional bolt kit that we sell WILL NOT work with the Ribbed style 14 bolt. You will need to reuse your factory bolts (if they are long enough) or purchase new metric bolts with thread pitch (M8 X 1.25)

This is our basic differential cover, we see it as the only one worth making. The Corporate 14 Bolt axle is found in Chevy 3/4 Ton Suburbans & 3/4 & 1 ton GM trucks, what they end up in is up to you. 

The Differential cover is a 1 piece Plate steel cap 3/8" (.375") bent 8 ways then welded to a 3/8" ring! One of the reasons it is so strong is that we manufacture it out of A50 Plate Steel, thats 50,000 PSI Tensile strength. After welding the mounting surface is machined absolutely flat for a perfect fit! Its a great addition to the already nearly bombproof 14 bolt axle. 

This is for a fully welded 14 Bolt Diff Cover, ready to plug & play


This one has seen a bit of abuse and look! No Leaks! I think this one is the best testimonial available, I can't say it better than the Picture can!
