10 mm Wrench
Recently got this 10mm Wave Drive wrench. I hadn't seen this before, but I had some stubborn sway bar bolts. This ended up working fantastically! Love the long length, and it really does great on rounded 10mm bolts. I've been impressed.
10 mm Socket
What's life without a few missing 10 mils? Surprisingly I had one for 20 years that had worn out. Got this one as a replacement and it's been great. Impact rated, and stepped down so it fits in tight places.
Telescoping Magnet / Mirror
A Telescoping Magnet is one of those little things you should never be without. It may seem insignificant but drop a bolt down the black hole of an engine bay and this little gem could save you literal hours of frustration. To a lesser degree the mirror is handy too. A set like this covers all the bases.
15-in-1 Ratcheting Screwdriver - Klein Tools
I usually stay away from the multi-tool screwdrivers because they're so often complete junk. This thing has totally changed my mind. Having one that's Klein quality makes all the difference.
This is now my go-to screwdriver 90% of the time!
205 Piece Mechanic's Tool Kit
These tool kits are something else I've had numerous versions of over the years. I bought this one when I bought the Suburban, and it's without a doubt the highest quality, cheap toolkit I've ever had.
Whether you're just getting started, or just looking for tools to keep in your trunk. . .This is a fantastic option!
Quality Tire Pressure Gauge
Checking your tire pressure regularly is another one of those often overlooked maintenance items. Most of us end up using some cheap, ancient slide gauge, and that doesn't always make for a very accurate reading. I recently got tired of the old junk and got one of these. Makes for much more accurate pressures!
