    Does an aluminum diff cover really help with heat? I can not decside to get the finned aluminum covers or to get some larger steel ones. I really mostly play in the mud and driveon the road. TIA /forums/images/graemlins/ears.gif

    Sounds just like a more vulnerable, weaker part that'd be easier to break. Sure, it might release some heat, but who cares?

    If you want to do something really nice for your diff, use synthetic fluid.

    Generally aluminum dissipates heat faster = good, and *MOST* aluminum diff covers hold extra fluid compared to stock = good.

    Potential drawbacks: Aluminum covers are generally thicker (especially cast aluminum) which is more potential for interference/clearance issues (depends on what you do, mud not a problem...rocks maybe a problem). Cost $$$

    For a mud truck or tow vehicle aluminum is great, for a rock crawler or abuse rig, I would go with a heavy duty plated steel cover for protection/strength.

    I think the best compromise would be to get one of those cheap thin aluminum covers and then just get one of those hella beefy rock-ring type protectors for it... then it would disipate heat the fastest and be tough enuff for rox.

    If it's for the front be sure it will fit without interferrng with the tie rod. Most companies that produce the finned aluminum covers offer 2, front or rear (same theory would apply to the custom cover).

    I have these 2 covers sitting on my desk as paper weight:
    [​IMG]

    These are the ORU covers to fit the D60 front and 14FF. Both are heavy but not like the custom made covers others offer.

    4WOR did a dif cover test a few months ago and the only thing the aluminum covers did not pass on the testing was the crushing test because they used a front end loader and bucket to crush it. /forums/images/graemlins/tongue.gif

    The front cover is not as deep as the standard D60 rear covers which are about as deep as the 14FF cover shown in my pic. The front coever is shallower to allow tie rod movement and clearance.

    I don't do rocks because we don't have any around here. So these covers will last and hold up just fine. /forums/images/graemlins/thumb.gif

    Just haven't put them on yet. It's not a high priority to get them on either as I need to do other important stuff to the truck before trying to make it look good. /forums/images/graemlins/rotfl.gif

    I use the ORU rear D60 cover. So far so good. I like the extra capacity and heat disapation. I drive my K5 to the trail head. Usually 2-4hrs on the Hwy. I took my K5 from Cali to Utah and back too. I do rocks but I am not a rock whore like some fellas around here. My cover has taken some hits and so far it just scrapes it. Some of the fins at the bottom are 'smooth' now. Perrty tuff cover but I would hate to have it take a dead center hard SMAK... may crack instead of bend? I thought about making a 'Rock Ring' for it....
    Good Luck

    They are show. If you have ever looked at a Finned aluminum cover after its been drug through the rocks, you will know what I'm talking about.

    Try www.mo-offroad.com for some beefy diff covers. Anyone who was at Midwest Spring K5 Thing 2003 in Hot Springs knows how tough they are. Remember Earl driving Laynes truck?... /forums/images/graemlins/rotfl.gif Broke a huge boulder in two!

    It is my opinion that a R/P will benefit from an aluminimum cover ( heat disapation ) when lower gears are used at constant highway speeds under load . Ex: Super Duty F-450 Dana 80's come with a factory aluminium cover because they come with 4.88's /5.38's and there intended useage.
    I would use a heavy duty steel diff cover in the rocks - even if real deep gears are being used , the R/P does not turn fast enough to benefit from the heat being dissapated(sp) by a aluminium cover .
    I have a finned aluminium cover on my pull truck that see's highway speeds, under load , and very little off-road - but my off-road truck has steel covers on it for protection .
    This is just my opinion - Tom

    With that said. The MOO covers also offer higher capacity which means cooler running operation. Probably cooler than the Aluminum cover.

    K5BLT4FUN drove his from Missouri to Moab and back without problems. I would say if you have a problem with the rearend heating up, you should look elsewhere for a problem rather than trying to cool them down.

    id of bought a rear aluminum one if it wasnt so dern expensive, so i settled for the chrome, and 84 k10 supplied me with a front 10 bolt one /forums/images/graemlins/smile.gif i like the looks of shiny things especially on a sunny day. /forums/images/graemlins/thumb.gif, id go with the aluminum. wont rust too, and chrome surface rusts, and its a PITA to shine up /forums/images/graemlins/thinking.gif

    the minuses of aluminum are easily eliminated with some sort of rockring diff guard... and the cooling benefits remain...
