: Riddler Diff Covers

I had RockStomper (Solid) diff covers, which I was pretty happy with, but one of them was slightly porous and weeped fluid through the surface. Not enough to cry about, but enough to bother to me a little. I was going to live with it, but when I saw the Riddler Diff Covers (http://www.trailduty.com/product_info.php?products_id=618), I decided I had to have them.

These things are substantial, nearly 12 lbs a piece, and look rock solid. Like most of the diff covers, they come unpainted, so I just rattle canned them black. They come with stainless steel hardware and a small rube of Permatex sealant, although I use paper gaskets as they are much easier to clean up after.

I understand that they were designed by the same person who designed the Crane high clearance diff covers, hence the resemblance. They are also identical to the Genuine Gear G2 (http://www.trailduty.com/product_info.php?products_id=566) covers, apart from the logo on them.

have you ever tried the lubelockers gasketsI've used reusable gaskets on other vehicles, (or at least I did until a gear shop threw them away), but just never gotten around to getting any for the JK. I use the paper ones which are cheap and easily cleaned off. I used to use RTV, but got real fed up with cleaning it off.

Those are my favorite cast diff covers because they are ramped at the mounting flange.

I put the Riddler covers on my front and back diffs. I really like them but ran into a problem on the front. I have the RE 3.5" lift and found that the front cover hit the track bar when the suspension was at full compression. I changed to the Full Traction track bar since it has a forward bow around the diff cover and thought that would solve the problem - but it didn't. We tried "clearancing" the cover a bit and that didn't help either. I finally went back to the stock front cover (the rear is fine).

I believe that the clearance problem depends on how much castor you run at the front - if you add in more castor there will be more clearance so others may not experience the same problem that I did. But, it's worth checking this to see if you have an issue.

I had the front apart today to swap my bump stops and didn't notice any issue, but I wasn't looking.

My track bar is raised at the axle end with a Poly bracket, so I don't think it will be an issue, but I'll definitely check.
