JustinOlson Posted November 1, 2006 Share Posted November 1, 2006 I'm looking at welding in a rear diff mount when I install the R230. Would I be shock loading the rear diff case too much if I solid mounted it to brakets welded to the chassis? Regards, Justin Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 1, 2006 Share Posted November 1, 2006 Lots of racers solid mount the diff. I think the issue is that the brackets that attach to the chassis have to be strong enough and have to spread the load well. Cover those bases and I think you're good to go.

blueovalz Posted November 2, 2006 Share Posted November 2, 2006 One issue that has been much discussed (and debated) is the suggestion of either all solid, or all flex mounted attachments. Solid mounting of either the front or rear (but not both) will very likely result in the solid mount tearing away or fatique failure at some point. Solid mounting only one end of the differential still allows the other end (the flexible mount) to move, focusing all this stress onto a solid mount that was not designed to be flexed. Eventually, the constant bending will result in failure. By solid mounting both ends, you eliminate all movement, which results in a durable and long lasting mounting system.

JMortensen Posted November 2, 2006 Share Posted November 2, 2006 Good point Terry. If you search you'll find threads about this, including one from bjhines where he shows pictures of the stock front crossmember that's been cracked from the stress. Solid mounting the mustache bar as well should eliminate that problem. Quote Link to comment Share on other sites More sharing options...
