hi, could any of u guys explain the need for diff risers, does it stop the slip u sometimes get from lay shaft cog and the main diff cog, sometimes i can hear mine slip under hard throttle over the rough ground, even thought everything is tight up on the cogs,engine mounts etc, just wondering if am in thinking in the right direction, thanks guys

As far as I know, the riser are only necessary with the upgraded limited slip diff housings with the 'hump' around them.

Like the picture attached (pardon the mud)

ok thanks for your advice

yes thats the only reason y you need them

i thought there was other advantages, like less rocks getting caught or something

Good point JD. Raising the diff does tend to allow small rocks and debris to get out instead of digging into the diff.

Hellya has an interesting fix - put silicon caulk between the chassis and the diff tube.

- Put a piece of tape on the tube to prevent caulk sticking to it.
- Fill in front, under and back of area between diff tube and chassis.
- Let it cure.
- Rotate diff to remove tape.

It creates a close-tolerance barrier to keep stuff from even getting close to diff tube.
