Artec Hardcore Diff Cover for GM14T with 3-8" Bolts

The Artec Hardcore Diff Cover for the GM 14-bolt (10.5") axle replaces the flimsy factory stamped cover with a thick nodular-iron casting built for 1-ton abuse. This is the version for non-ribbed GM 14-bolt differentials that use 3/8" cover bolts. If you run a full-float 14-bolt under a swapped Jeep, buggy, or full-size rig, it protects the ring gear and carrier from the rock strikes that flatten a stock cover.

Key Features

• Cast from high-strength nodular iron for extreme-impact protection
• Thick-walled design armors the large 14-bolt ring gear and carrier
• Magnetic drain plug removes metal shavings from the gear oil
• Durable powder-coat finish over the casting
• High-strength steel fasteners included
• Correct pattern for non-ribbed housings that use 3/8" cover bolts

Fitment & Compatibility

Fits the GM 14-bolt (10.5-inch ring gear) axle — specifically the non-ribbed differential that uses 3/8" cover bolts. If your 14-bolt has a ribbed differential housing with metric 8mm cover bolts, order the GM14T cover for M8 bolts instead. Check your cover-bolt size before ordering.

Frequently Asked Questions

Which 14-bolt does this fit?
It fits the GM 14-bolt (10.5-inch) axle with a non-ribbed differential that uses 3/8" cover bolts.

How do I know if I need the 3/8"-bolt or the M8-bolt version?
Look at your existing cover bolts. Non-ribbed housings use 3/8" bolts (this cover); ribbed housings use metric 8mm (M8) bolts, which need the M8 version.

Does it require welding?
No. It is a bolt-on cover installed with the included high-strength fasteners.

Does it come with a drain plug?
Yes, a magnetic drain plug is included.
