ARB | OME Nitrocharger Plus Rear Shock Absorber

For 1990–1995 Toyota 4Runner 4WD

Overview

The ARB Old Man Emu Nitrocharger Plus Rear Shock Absorber is the dedicated rear-coil shock application for 1990–1995 Toyota 4Runner 4WD models. This application uses one rear-shock tune with compatible Old Man Emu rear coil springs, so the only customer choice is quantity.

Its heavy-duty twin-tube, nitrogen gas-charged design provides controlled damping for daily driving, towing, hauling, overlanding, rough roads, and off-road terrain.

Key Features

• Vehicle-specific tuning for 2nd Gen 4Runner rear coil-spring suspension
• One dedicated rear-shock application
• Designed for stock ride height through approximately 2 inches of rear lift
• Heavy-duty twin-tube steel construction
• Nitrogen gas-charged design
• High-flow piston with multi-disc compression valving
• Direct fit at the factory rear shock mounting locations

Nitrocharger Plus Design

The Nitrocharger Plus uses a durable twin-tube steel shock body to protect critical internal components during demanding road and trail use. Its nitrogen gas charge, high-flow piston, and multi-disc valving help maintain consistent damping as the rear suspension moves through changing terrain and vehicle loads.

Stock Height & Lift Compatibility

This rear shock supports factory rear ride height through approximately 2 inches of rear lift. The shock absorber does not create vehicle lift; rear ride height and load support are determined by the coil springs and the overall suspension configuration.

Which Rear Shock Should You Buy?

KYB Excel-G — Best for Factory-Style Comfort & Value

Choose KYB Excel-G for an affordable, factory-style replacement that prioritizes comfortable everyday driving and original-style ride quality at stock height. Its gas-charged twin-tube design emphasizes smooth, predictable damping.

KYB Gas-a-Just — Best for Firmer Stock-Height Control

Choose KYB Gas-a-Just for firmer, more responsive monotube damping without stepping up to Bilstein. It offers a more controlled ride feel without changing suspension height or vehicle load capacity.

Bilstein B6 4600 — Best for Overall Stock-Height Performance

Choose Bilstein B6 4600 for premium monotube damping with controlled, responsive handling during daily driving, highway travel, and light off-road use.

ARB / Old Man Emu Nitrocharger Plus — Best for OME Suspension Builds & Added Weight

Choose OME Nitrocharger Plus for 1984–1989 4Runner 4WD models with matched OME suspension setups, frequent rough-road use, or additional permanent equipment weight. Medium and Heavy valving options support stock height through approximately 2 inches of rear lift.

Our Recommendation: For most stock-height Toyota 4Runner owners, Bilstein B6 4600 is our preferred all-around choice. Choose KYB Excel-G for factory-style comfort and value, KYB Gas-a-Just for firmer budget-friendly control, or Old Man Emu Nitrocharger Plus for 1984–1989 4WD suspension builds and more demanding use.
