I Finally Did It - Peak Suspension Summit Kit Installed On My AT4X

Описание: 🎬 This Episode: I finally install the Peak Suspension Summit Kit on my GMC Sierra AT4X and find out if it was actually worth it.

After running the factory DSSV Multimatic shocks with nearly 900 lbs of constant weight from my Decked drawer system, SmartCap, and rooftop tent, the ride quality just wasn’t cutting it. I tried airbags to compensate… and that only made things worse.

So I decided to stop patching the problem and do it right.

In this video, I head to Riverside, California to Peak Suspension headquarters to have their full Summit Kit installed - including 2.5” remote reservoir coilovers, billet upper control arms, rear remote reservoir shocks, new rear blocks, and Deaver M27 leaf springs.

We go over:
• Why I ditched the DSSVs at only 6,000 miles
• How much lift I gained front and rear
• What happened to the airbags
• First impressions on and off pavement
• Whether this setup can truly handle a fully built overland rig

The result? A completely different truck.

If you’re considering upgrading your suspension, this one’s for you.

✅ ABOUT THIS CHANNEL
Welcome to Rim Country Overland—a channel built around one guy, one rig, and wherever the dirt leads.
I explore backcountry trails and remote campsites in my 2023 GMC Sierra AT4X—The Blue Beast—sharing the real-world side of overlanding: gear that earns its keep, mods that make sense, and the occasional trail fail that keeps it honest.
This channel is about more than just installs or gear reviews—it’s about what works when you're out there, and what doesn’t. Whether I’m wrenching in the garage, hitting the Arizona high country, or figuring it out on the trail, I’m here to bring you along for the ride.
If you’re into dialed-in rigs, solo exploration, remote camps, and rugged gear that gets used—not just unboxed—you’re in the right place.
Thanks for riding along - I'll catch you on the next adventure.
