Made My Own Diff Drop Spacers Have Questions

Made some diff drop spacers (35mm OD, 15 ID, 10mm thick) although I'm not sure it's required for a 2" level? Also why do the kits only have 2 spacers when there are 3 attachment points ? Anyone know the length of the stock fasteners?

I made my own as quite a few have, Do a search, there are several threads that will tell you the length of bolt you will need. I bought mine at the hardware store.
You keep the back bolt in-no spacer, which will give the drive shaft the correct angle, you do need to LOOSEN that bolt a few turns to be ble to manuaver the diff around



I would have to figure out in US measurement what 10mm is to determine how long of a bolt you will need. If 3/8's then you can use the stock bolts with no problems.

Yes 10 mm real close to 3/8" So there's enough thread on the stock bolts to use them?

IMO...you're adding 10mm gap so get a 10mm longer bolt. There's a certain # of threads for a reason. It's not like you're buying a $pendy part & you already saved $$$ by making your own spacers.

You probably wont find a bolt that is 10mm longer. Just get a bolt 1/2" longer and call it good, or for exactness, grind .1063" off.

My comment mainly in regard to the attachment points. There's 3 but we only use 2 of those. Seems kind of strange to me. It's lower but rotated back in regard to the C/L of the output shafts in my mind. From searches I've never seen this question answered.

Usually metric fasteners are in mm length increments. At least where I work

I didn't ask this....I asked if anyone knew the length of the stock fasteners. You know so I can have them "in hand" before starting the work. But hey thanks for your comment

Your only lowering the front portion of the dif. So there are only 2 front mounting points. I installed the 1 inch dif drop and didnt like the angle it put on the mounting bushings because your angling it down in the front. It looked like over time that bushing would give out. I thought of doing only a 1/2 in drop would be better.
