Using aluminum components, heat-treated 2024 aluminum alloy pistons, and extremely high 100,000 psi tensile strength shafts, which create the ultimate surface hardness against debris.

Off-Road Racing Royalty!
The King Shocks are about as good as it gets for an off the shelf shock set for the Gladiator. When we installed the King 2.5 adjustable shocks on our JT Mojave it completely changed the truck, it feels extreamly smooth and well behaved everywhere we go.

Fantastic Setup
I have a 2019 tundra CrewMax. Purchase a set of King coilovers w reservoir. I also have the Icon expansion leaf pack. This combination works exceedingly well. I drove ~75% on road and 25% off-road /trails/fire roads. Absolute game changer. The ride is much more plush, I don't feel like I lost any cornering control. Quick shipping. I would absolutely do the setup again.

Best Setup I've Ever Had
Paired these with deaver m27 leafs and it’s the best my truck has ever felt. I’ve tried fox 2.0’s and bilstein 5160’s and this blows them out of the water. They’re plush on the street and you can firm them up to take on whoops at 40+ mph.

The Expert's Opinion

"King Shocks are everything you'd expect from this legendary brand, right out of the box. Comfortable on the daily drive, while handling faster speeds off-road as they're meant to. Custom tuning isn't a necessity for most drivers, but its good to know that it's available.

Shock Surplus' $250 Service/Rebuild credit towards future needs is a no brainer!"
