I eat them like candy. Lets here what you guys are doing to solve the problem. I have busted 3 and tore the tab off my old subframe twice. Im ******* over it.
I can make almost anything at my new work and im thinking of a solid unit...

I run a fully built subframe and Delrin diff mounts, stock, beat *** lower crowns. I like alot of grip in my setup. Pinion snubber has been in for the past 2 mounts.

What are you guys doing for this, its annoying as FACK.

 

Are you preloading your pinion snubber on the diff or no?

 

Dude,box it in with 3 plates... Pound till flush and TIG or MIG

went through three in three drift events, put in a Nissan truck bump stop and bam, no more broken mounts. It's hella preloaded, that's the key.

 

also depends on the material the stop is made out of as to how much give it will have.

 

If your gonna box/weld the front mount like Zenki said, make sure you preload the **** out of the pinion snubber so you dont shear again.

I'm thinking of putting a second bump stop on mine somewhere... if i can make it work

 

I like the thought in that second link spinna posted, but I think it would be better to use something like a clevis and sway link instead of the ghetto oversized hole.

 

^I agree on the sway link
