Rockcrusher Diff Covers

Inc · **Posted:** Thu Jan 01, 2009 2:29 am

I installed my Rockcrusher Diff Cover a while back and it went on a whole lot easier than the Ruff Stuff I took off. The Ruff Stuff was beefy as beefy can be, but the welds seeped a little and it drove me nuts. I dropped on that cover quite a few times and it held like a champ though. Anyway, this Rockcrusher is nice! It went on much easier than the Ruff Stuff. It has a wider flange lip that sits against the axle and allows for more finger room when installing. It is .250 thick and has ribs for extra strength. Lifetime guarantee on them too. When I picked mine up from the local shop, he just got off the phone with the owner of the company and the owner bet an employee a year salary that he couldn't break it. The guy could hear the employee banging on it in the background. I have a pic of mine installed but can't find the camera cord to upload it. Here is a stock file pic of it though. Mine was just over $100 out the door after shipping and tax.

Anyone else running one of these?

BTW Tom, I took all the red off that Ruff Stuff cover. The only things really left on it is the RTV in the bolt holes. There is a little residual in there. That cover looks almost as nice as it did the day I got it from Dan.

Well I ran out of red paint so I couldn't touch the Ruff Stuff one up before I shipped it so instead of shipping a kind of thrashed looking one I cleaned it up a bit. The new one is all black. I am still out of red paint though, but when I get some the red oval with the lettering will be red as well as the bolts, I think anyway.

how hard are those to install?

i know you have to drain the fluid and all...but overall how hard?

simple, just barely harder than an oil change.

unbolt and pry at the bottom of the cover to let it drain, then remove all of the bolts and take it completely off and clean off the old RTV and apply new RTV all around the diff cover and bolt back on wait 10 min for the RTV to dry and fill with fluid

Looks nice. I just received one for a HP D30 from Solid - looks pretty similar. I think they all use the same castings

I believe they used to be the same company but someone broke off and started one or the other. Same kind of deal as Riddler and Crane.

Rockcrusher was first and they are made in Australia. The guy that makes the Solid covers used to be the US distributor for Rockcrusher. He started making knock offs and when Rockcrusher found out, he had to stop calling them rockcrusher and changed the name to Solid.

I've got a Riddler diff cover from Rokmen. Very beefy, lifetime warranty, and was $100 delivered. It's the one the ran over with a 150,000 lb vehicle to finally break.

Rokmen's price is now $124.95 for the Riddler though. Plus shipping.

Looks beefy!! The fill plug looks higher on the Rockcrusher one, than stock. Can anyone confirm this? If true, would this cause problems??
