8.8 Aluminum Differential Cover Rear End Girdle System For Ford Mustang Premium Quality - Silver Finish

I had this diff cover installed and my entire rear end professionally rebuilt by DTS in Warren. I installed the 8.8 and added Royal Purple Gear Oil with the Ford friction modifier. This was installed with a Lube Locker gasket from LMR. I used 3 quarts of gear oil for the install due to the extra capacity of 20oz listed by the manufacturer. After one night of being installed the diff cover began leaking from the drain plug hole. I cleaned everything up nice and retightened the plug. It still leaked the following day. Amazon customer service was kind enough to issue a full refund and is working with me for additional information to report back to the vendor. I intentionally purchased this diff cover based on the reviews and to save money on name brands. Ended up wasting over $60 in fluids and now i have to spend time to fix everything back up. Do yourself a favor and consider this before buying.

Very thick and steardy cover. Have 4.30 gears amd it had no issues. Covering them. Painted on the inside so either sand blast the inside or buy cheap gear oil and let it come off that way. Just make sure to change it after 150 miles. No leaks and makes ther rear pop out

Great cover for the price! Solid construction! My only complaint is that the cover was painted silver not an aluminum finish. I took a sanding disk to it to bring out the natural color. Also the through bolts to set bearing preload will leak gear oil if you do steep inclines. I'm assuming it might let water in. I just put ultra black rtv on the threads to stop the problem. I.m also going to assume that any cover of this design would do the same.

Looks nice, beefy, nice sturdy cover for the money

i thought it would turn up raw cast ali, turns out its been painted silver. paint on the outside isn't so bad but its painted it on the inside too! last thing i wanna risk is the lsd oil dissolving the cheap paint and messing up my rebuilt axle. now i'm gonna have to sand blast it to get the paint off. Also don't expect it to be the same level of quality as the ford racing one it simply isn't. plus points it is very thick and pretty sturdy and if you dont care about overall looks it is perfectly functional but its needs a better overall finish to compete with the ford one. also the supplied bolts were already starting to rust, it would have been a nice touch to provide stainless ones, but hey it was cheap so you get what you pay for.overall not bad but nothing special either

Fits all Ford 8.8 differentials -- F-150s, Mustangs, Crown Vics, Town Cars, & Grand Marquis perfectly.Installs in about one (1) hour.This is a quality, heavy aluminum casting -- it will strengthen your differential housing for towing and/or racing.The stock Ford 8.8" differential tries to destroy itself under hard acceleration and/or heavy bearing load.This differential girdle casting is the perfect answer to those problems !!Warning -- This girdle is PAINTED on the INSIDE, and the paint must be removed before installing to prevent the Gear Lube fromdissolving the paint and sludging-up the whole differential !PARTS IN KIT AS DELIVERED:1 DIFFERENTIAL GIRDLE ASSEMBLY.1 GIRDLE GASKET (not used, see below)10 FLAT WASHERS10 LOCK WASHERS10 CAP SCREWSDIFFERENTIAL GIRDLE INSTALLATION INSTRUCTIONS:STEP 1. Remove old differential cover.STEP 2. Inspect all internal components for visible defects and repair/replace at this time.STEP 3: Clean inside of axle housing thoroughly and carefully remove any gasket material or sealer from the mating surfaces.Before proceeding to step 4, prepare the girdle and gasket -- Install the drain plug, using Permatex Ultra Black on the threads to prevent any leaks. Make sure the load-bolts are backed out to prevent contact with the bearing caps while installing the girdle.NOTE: The supplied paper gasket was not used -- I opted for the LubeLocker Part Number LLR-F880 FORD. The LubeLocker gasket is made of steel, with a rubber coating on both sides. It has an elastomer sealer on both sides that is applied at the factory, and the gasket is re-usable.The LubeLocker (made in USA) gasket comes with a diagram for the bolt-tightening sequence. USE THE DIAGRAM for maximum strength and NO-LEAK results.STEP 4: Install the girdle with the gasket, bolts and washers. Bring the bolts up to "snug", using the LubeLocker pattern..STEP 5: Using a good torque wrench, torque the girdle to the axle cap screws to 25 ft./lbs. , and DO NOT OVER-TIGHTEN !!STEP 6: Hand-tighten the two load bolts until they make contact with the differential bearing caps.STEP 7: Torque the load bolts to 90 inch/lbs.--- (7.5 ft/lbs) Excessive torque can damage the differential bearings!Torque the jam nuts to 25 ft./lbs.STEP 8: Remove FACTORY fill plug, fill differential with recommended lube from the upper hole in the girdle until the fluid runs out of the FACTORY fill hole in the side of the differential housing casting.I applied some of the Permatex Ultra Black to the fill-plug and drain-plug threads -- to insure against leaks.I used Mobil1 75w90 LS Synthetic Gear Oil -- Standard capacity is 3.75 Pints, (60 Oz.), but the new Girdle requires 5 Pints (80 Oz.).This unit makes the rear-end assembly stronger, allows the differential to run cooler, and the extra fluid capacity allows for longer change intervals.After a proper round-trip shake-down cruise across the desert from Phoenix to Palm Desert, Ca., in 100+ degrees, I checked the differential temp with an Infra-Red gun, and the differential runs about 20 degrees cooler than it did with the OEM cover under similar circumstances.Customer Image shows the heavy-duty diff cover and LubeLocker gasket installed on a '95 Mercury V-8.

Good cover but very cheap gasket. Rear end leaked the next day. Now all my money on the fluids is gone. How can thus be resolved?

This is no less of a product than those with a name stamped on the back of it. It is thick and has all the reinforcement as any casting costing twice as much so I'm not worried about warping it. I will take a burring bit and clean up the inside where the drain plug hole has cast flash but other than that I'm not wishing I bought another brand.
