where to buy the fiberglass 7.5 diff cover?

[chrwilkins30]

Plan to change diff fluid but want to swap to the factory fiberglass ones to cutdown on rust. Went to the JY but they pop holes in them all. anyone know where to get them.

I also want to make a rock guard just because. I dont really go offroad but its a little project I could do with a 110v HF welder and I think I would look cool. Thanks

Just buy a good aftermarket one (like aluminum)...'glass will break and leave you stranded like a duck out of water. Go to Ebay and get a good one or check here on this site and see if we have them. Go to your local 4x4 shop. We sell gears here as well.

if it is the same as an 8.8 i have one off my truck i would sell you mine for $30.00 shipped let me know

 

[chrwilkins30]

no need for an aluminum cover as I don't off-road. Just want to get rid of the rusty ass metal cover.

And the 8.8 is a different size. I need for the 7.5.

Anyone else know where to get one.

Well I've heard of them before but some guys have clear composite covers. Or you could just get an aluminum cover with a sight glass in it.

 

[chrwilkins30]

is there any vehicles that came with the 7.5 with maybe an aluminum cover.?

honestly, just get a new steel one, and paint it... if you prep it properly, and use the right paint, it will never rust on you...

You don't live in the rust belt do you? He's in Indiana, paint will not survive here. Though ultimately (as later described) I do agree on a steel one. But never rusting is just an outright fantasy here.

Option 1) I'd go to a different junkyard, both of them by me leaves everything in them. I don't think you're going to find a new composite diff cover for the 7.5" anywhere new, maybe a dealer but that's going to be cost prohibitive, but you never know.

Option 2) High end cast aluminum. In all seriousness, unless you decide to shell out $150 or so for one of the fancy aluminum covers, it's your only rust proof option. I bet you've looked into them though. And in that case, you could buy a TON of regular steel covers (likely enough to last the life of the truck and then some).

Option 3) Try taking the cover (either the old one after being sand blasted or a new steel one) to a place that does truck bedlining and tell them to use a smooth application and see what they say. That would take ages to rust through and I would sure hope be under $75. Even with a smooth coat, I'd bet that silicone would be your only sealing option after that, and be sure to get the good kind.

it seems like i have a fiberglass cover on my 7.5 but i dont remember. it's gettin ripped out in a few weeks, you can have it if it is....i'll check on it when i get home from work

 

[chrwilkins30]

Yeah those aftermarket aluminum are way to expensive. If I would ever buy one it definitely wouldn't be for a 7.5.

Yeah if you paint something here in indiana. It looks good for maybe few summer months but once winter comes that salt makes everything look like shit.

And eddie that would be awesome. How much would shipping be?

it's a diff cover... if it isn't broke, why fix it?

 

[fastpakr]

7.5" differential cover, $37.77.
Coupon 'VISA' gets you $10 off 30, or add a couple of bucks and use 'BIG15' for $15 off 40.

 

[kemo]

Here is a deal, get that diff cover, add 4 pureone oil filters... use code BIG25. THEN, use the rebate to get a total of $12 back from the 4 pureone oil filters. brings the grand total to like 32 bucks after rebates and tax included. (that's estimating on the high end)

 

[fastpakr]

Great find! Here's the link for the rebate form.

where i live now, they don't use much salt, it's too cold, instead they use... potassium chloride (KCl)? instead of sodium chloride (NaCl [salt])

the chemical they use here is like a reddish white stuff, mixed in with sand and gravel, and leaves a white residue on all vehicles HOWEVER, where i used to live they use a tonne of salt, as the temperature normally doesn't get below about -10 celcius, and salt is extremely effective in that temperature range
