ARB | OME Nitrocharger Plus Rear Shock Absorber
For 1979–1983 4WD Toyota Pickup
Overview
The ARB Old Man Emu Nitrocharger Plus Rear Shock Absorber is a vehicle-specific suspension upgrade for 1979–1983 Toyota Pickup 4WD models.
Designed for stock ride height through approximately 2 inches of rear lift, the Nitrocharger Plus provides controlled damping for daily driving, towing, hauling, overlanding, rough roads, and off-road use. Old Man Emu vehicle-specific valving helps maintain predictable suspension behavior across changing terrain and vehicle loads.
These shocks can be used at factory ride height or incorporated into a properly configured OME suspension system using compatible Old Man Emu rear leaf springs.

Nitrocharger Plus Design
The Nitrocharger Plus uses a durable twin-tube steel construction designed to help protect the internal working cylinder from road debris, trail impacts, and demanding operating conditions.
Its nitrogen gas-charged design, high-flow piston, and multi-disc compression valving help maintain consistent damping during repeated suspension movement, including highway driving, towing, overlanding, and off-road use.
Stock Height & Lift Compatibility
These shocks can be used at factory ride height or as part of a properly configured suspension system providing approximately 2 inches of rear lift.
The shock itself does not lift the vehicle. Rear ride height is determined by the leaf springs and overall suspension configuration.
When paired with compatible Old Man Emu rear leaf springs, the Nitrocharger Plus can be incorporated into a complete OME mild-lift suspension setup.
Available Valving Options
Two Nitrocharger Plus rear shock valving options are available to match different vehicle weight configurations.
Medium Load
-
Best suited for stock-weight or moderately modified vehicles
-
Appropriate for daily driving and lighter cargo loads
-
Provides a softer, more compliant ride
Heavy Load
-
Designed for vehicles carrying constant additional weight
-
Better suited for steel bumpers, tire carriers, drawer systems, roof racks, camping equipment, or other permanently installed accessories
-
Provides firmer damping and additional control under sustained load
Select the valving option that most closely matches the vehicle's normal operating weight and permanent equipment.

Old Man Emu vs. Bilstein B6 4600
Bilstein B6 4600: Better suited for lighter, mostly stock-height daily-driven Toyota Pickups where responsive handling, controlled damping, and on-road performance are the primary priorities.
Old Man Emu Nitrocharger Plus: Better suited for frequent off-road use, additional vehicle weight, towing, hauling, rough-road driving, or trucks using other Old Man Emu suspension components.
Quick Recommendation: Choose Bilstein B6 4600 for a primarily stock-height daily driver. Choose Old Man Emu for heavier builds, frequent off-road use, or a complete OME suspension setup.
We offer both Bilstein and Old Man Emu rear shock options.
