Old Man Emu - Nitrocharger Plus Suspension Kit with Upper Control Arms - Toyota Tundra 2022–Current
OLD MAN EMU NITROCHARGER PLUS OVERLAND SUSPENSION
Everyday Comfort. Purposeful Capability. Ready for the Miles Ahead.
Build your Tundra around the way you travel with the Old Man Emu Nitrocharger Plus Overland Suspension Kit.
This matched front-and-rear system combines vehicle-specific struts, shocks and coil springs to deliver controlled suspension movement and support for your chosen equipment load. From weekday commuting to remote campsites, it brings a coordinated approach to ride quality, stability and overland preparation.
With approximately 3 inches of front lift and 2 inches of rear lift, this package gives your Toyota Tundra a purposeful stance while offering two rear-load choices and optional heavy-duty upper control arms.
ENGINEERED AS A COMPLETE SYSTEM
A suspension upgrade should do more than raise the truck. Its springs and shocks should work together to suit the vehicle’s weight and intended use.
Nitrocharger Plus pairs vehicle-specific tuning with durable twin-tube construction, helping manage suspension movement across pavement, uneven backroads and trails.
-
Matched front-and-rear suspension components engineered to work together.
-
Heavy-gauge twin-tube shock construction for demanding conditions.
-
Five-position front spring-seat adjustment for installation-time setup.
-
Load-specific rear springs to match your permanent equipment.
-
Optional Old Man Emu heavy-duty upper control arms.
-
Included sway-bar and brake-line spacer kits.
All four configurations use the same front springs and struts. Your selections determine the rear spring package and whether upper control arms are included.
STEP 1 — SELECT YOUR REAR LOAD
Light Load (Stock Rear Weight)
For a stock or lightly equipped bed and occasional camping cargo.
Choose this option when your Tundra normally operates without a substantial permanent rear load.
A suitable choice for:
-
Daily driving with a mostly empty bed.
-
Lightweight bed accessories.
-
Camping equipment loaded only for trips.
-
Tools and cargo that are regularly removed.
This is the lighter-load configuration—not a statement that the truck cannot carry cargo.
Overland (Constant 440 lb)
For approximately 440 pounds of equipment that stays on the truck.
Choose this option when your overland setup carries a combined permanent rear load around the specified weight.
Equipment may include:
-
Bed rack and rooftop tent.
-
Camper or canopy setup.
-
Drawer and storage systems.
-
Rear bumper and recovery equipment.
-
Permanently mounted tools and accessories.
Choose by actual permanent weight—not accessory names alone. Occasional passengers and temporary cargo should not be counted as constant load. Heavier-load springs can produce a firmer ride when used without the intended equipment weight.
STEP 2 — SELECT YOUR UPPER CONTROL ARMS
Without Upper Control Arms
Includes the suspension system without a replacement upper control arm kit.
Choose this option if you already have suitable aftermarket upper control arms, or your installer has confirmed that your existing arms are appropriate for the intended setup.
Selecting this option does not guarantee that factory upper control arms will meet alignment and clearance requirements at every lift setting.
With Upper Control Arms
Adds an Old Man Emu heavy-duty upper control arm kit.
Choose this option when you want upgraded upper control arms supplied with your suspension package rather than purchasing them separately.
The front suspension and selected rear-load configuration remain the same. This option adds the control arm kit.
WHAT’S INCLUDED
Every configuration includes:
-
Matched front coil springs.
-
Two Nitrocharger Plus front struts.
-
Two Nitrocharger Plus rear shocks.
-
Rear coil springs matched to your selected load.
-
Rear sway-bar spacer kit.
-
Brake-line spacer kit.
When “With Upper Control Arms” is selected:
-
Old Man Emu heavy-duty upper control arm kit.
Upper control arms are included only when that option is selected. Product images may show optional components; your selected configuration determines what is supplied.
