This is what its all about! Kyle took our shock building 101 class this past Friday. He even got to participate and assist in breaking down and rebuilding a FOX racing shock during the demo portion of the class. I teach this class for free at every Overland South because it starts a thought process. Even if you don't plan on rebuilding your own shocks, simply knowing what's inside them, how they work, and having even an introductory glimpse into the suspension design and tuning world will allow a hobbyist to accomplish more with their vehicle.

And what better tool to have at your disposal right after a suspension seminar, than our RTI ramp, to test your vehicle in a safe and measurable environment. Big thanks to our sponsor Metal Supermarkets for the assist on the ramp that clearly helped this father/son team make some really cool memories.

Results from the RTI competition at the Swamp Fox Overland and Outdoor 2nd annual truck show and fundraiser for the Venture Unknown foundation.
Thank you to everyone who came out, competed, and helped raise a ton of money for a great cause. Keep tabs on the swamp fox page for an announcement of how much money was raised and some great event photos and videos.
In the words of the late great Warren Miller, "Hope to see you next year....same time, same place"

We had a fun Monday morning with Live 5 News on their Palmetto Life segment. Might be the first time an RTI ramp has been featured on broadcast television! Come out this Saturday to the Swamp Fox Overland and Outdoor truck show to support the Venture Unknown foundation.

Swamp Fox Overland is hosting a special event to raise money that will help protect the Francis Marion National Forest from litter and waste.

Another beautiful day in downtown Charleston, SC. Only a few more days before we trade the pavement for dirt.

Thanks for the photo Douglas Stephens
Really cool to know this hat went on a two day climb to the top of an active volcano, hours after this photo was taken.

Big strength, tiny welds. Grain of rice for scale.

When the hydraulic hole puncher cant reach, there's no better (or faster) way to drill clean, precise 3/4" holes in 1/4" steel plate than the trusy mag-drill. Bolting the new (to us), milling machine to this custom heavy duty table

Don't forget the Anchorlube from to keep those annular cutters running cool and sraying sharp for a long long time.
