Thread: Dog bone replacement mount setup... no more dog bones! Solid and it saves weight.

I should have three or four of these kits if there is interest - this mount kit was designed by Janice from ClubGP. I have this running on a locals turbo car and the car I took pics of for this which is a big supercharged build thats 350+ whp.

If anyone wants one Id probably let them go for $125.
If there is a decent amount of interest I could make more but it would have to be at least in lots of four to keep cost on the main aluminum piece down. Kit consists of 1/2" thick 7075 aluminum mount, steel plate with tabs TIG welded to it, two needed bolts, spacer for bottom bolt, washers, and one nut. The bottom bolt going through the tabs that secures the mount to the cradle is one of your stock bolts that you are replacing.

Final aluminum piece will be nicely cut on a band saw or water jet cut if I can get them to do it for a decent price. Installing the kit requires you to disassemble some things to gain access, MIG welding (can all be done from above), measuring, and drilling one bolt hole yourself in the aluminum piece (the bottom hole) either after accurately marking the hole with everything already welded and mounted or by drilling the hole on the car.






This is pretty much everything. The bolt going through the tabs is the stock trans > engine bolt.





I did all this from above I didnt get the best looking weld but it penetrated nicely and should hold just fine. Also, a suggestion made by Janice is to weld the seam on the front and back of the cradle piece that sits under the mount.


All bolted up and ready to go.


Update:
We have this setup on a car here making somewhere in the realm of 500whp.
He is maxing his 80# injectors and we will be going bigger with the fuel setup.
Car has virtually zero vibration in the cabin with this dogbone replacement setup.

I figured there would be at least SOME interest in this =p. Less weight, solid, looks better. Ill have a video of the car this mount was on running soon - its going to be a 350+ supercharged setup.

That's really nice. If I had a show car or needed to lighten the load on a track car, this would be fun for me.

Those sure do look nice

Thoughts on that one?

Isn't that where the vibrations are eventually going anyway? I mean, trans and engine mount are already there...

Not sure how strong a steel/Al weld would be or hold up as a main motor mount.

Perhaps steel is the way to go.

First google result. Does that help? Can I Weld Aluminum to Steel?

all mounted to the same place: the frame rails. what is the difference?

I may be making a bolt in version that will also work with the aluminum cradle. It will require drilling a couple holes obviously.

the bracket is steel and you welded it to the aluminum subframe? please explain this. Did you use a tig welder with aluminim filler rod or did you use an aluminum mig welder? Also..how long have you drove with that welder to the aluminum?

No. I would never try to weld steel to aluminum. I welded steel to a steel cradle.

then where the hell did this steel welded to aluminum bs come from?

i was gonna say, there was no way you tig welder steel to aluminum, because the aluminum has a much lower melting point, therefor the heat would not pentrate the steel before the alumimum melted away.

Aluminum cradle would require a bolt in mount. Getting down in the engine bay and TIG welding isnt my idea of fun at all.

We shall see...
