This is the hardware kit that buttons up your SG688 or SG688R steering gear install on a Jeep JK the right way. Everything in here is sized and matched to work together, so you’re not digging through bins or hoping the bolts you grabbed are close enough.

You’ve got the correct length 12mm bolts along with heavy-duty washers and lock washers to keep everything tight where it needs to stay. It’s a simple setup, but it matters—this is what keeps your steering gear mounted solid and doing its job.

When you’re putting a BIG BORE XD® gear on a JK, this is the hardware that finishes it off clean.
