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 — check your bolts before ordering, because ribbed housings take metric M8 hardware and a different cover. Whether the full-float 14-bolt lives under a swapped Jeep, a buggy, or a full-size rig, this cover keeps the big ring gear and carrier protected from the strikes that flatten a stock cover.

Features

• Cast from high-strength nodular iron for extreme-impact protection
• Thick walls armor the 14-bolt's large ring gear and carrier
• Correct bolt pattern for non-ribbed housings with 3/8" cover bolts
• Magnetic drain plug removes metal shavings from the gear oil
• Powder-coat finish over the casting
• High-strength steel fasteners included; bolt-on, no welding

To identify your housing, look at the differential casting and the existing cover bolts: non-ribbed housings use 3/8" bolts (this cover), while ribbed housings take the GM14T cover for M8 bolts. Building the whole axle? Artec's Dana 50/60/70 cover handles a matching 1-ton front, and the full range lives in our diff covers collection.
