The Modern Standard in Jimny Rear Suspension Performance , OME Nitrocharger Plus Built for the 4th-Gen Suzuki Jimny
The ARB ARB63155 Old Man Emu Nitrocharger Plus Rear Shock Absorber is engineered specifically for the 4th-generation Suzuki Jimny (2019-2024), combining the latest in ride control technology with the decades of OME off-road suspension engineering that made the brand the standard for Jimny builds worldwide. The ARB63155 features a large-bore, high-flow piston that reduces heat buildup under sustained off-road use and an advanced multi-stage valving system for superior responsiveness across the Jimny’s wide suspension travel range. A new triple-lip oil seal provides a tight wiper barrier against dust, mud, and water intrusion, extending service life in challenging environments. The ARB63155 is a direct replacement for the factory Jimny rear shock, using the OEM top-eye and bottom-eye mounting configuration at an extended length of 515mm and compressed length of 325mm. Backed by a 3-year ARB warranty.

Frequently Asked Questions
Is the ARB63155 sold as a single shock or a pair?
The ARB63155 is sold as a single rear shock absorber. Order two (2) units for a complete rear axle replacement.
Does the ARB63155 fit the JB74 Suzuki Jimny sold in export markets?
Yes. The ARB63155 is designed for the 4th-generation Suzuki Jimny JB74 platform, which covers the 2019-2024 JB74 Jimny sold in markets including Japan, Australia, and Europe. Verify your specific chassis and rear suspension configuration matches the JB74 spec before ordering.
Is the ARB63155 a direct OEM replacement for the factory Jimny rear shock?
Yes. The ARB63155 uses the OEM top-eye and bottom-eye mounting configuration of the factory Suzuki Jimny JB74 rear shock. It installs using the factory mounting points with no modification required.
Can the ARB63155 be used with a lift kit on the Jimny?
Yes. The ARB63155 has an extended length of 515mm (vs factory), which makes it appropriate for use with Jimny lift kits. ARB designs this shock to work within the suspension travel range expected when a lift kit is installed. Confirm the specific lift kit manufacturer’s shock length specification matches the ARB63155 before ordering.
What is the difference between the ARB Nitrocharger Plus and the standard OME Nitrocharger?
The Nitrocharger Plus incorporates an upgraded triple-lip oil seal, a larger-bore high-flow piston, and an updated multi-stage valving system compared to the standard Nitrocharger series. These improvements increase heat resistance under sustained off-road use and extend service life in demanding conditions.
Does the ARB63155 require any special tools for installation on the Jimny?
No. The ARB63155 installs using standard automotive hand tools. The top-eye and bottom-eye mount configuration uses conventional bolts that are accessible with standard sockets and wrenches. No spring compressor or specialized tools are required.
Is the ARB63155 compatible with the factory Jimny rear coil springs?
Yes. The ARB63155 is designed to work with both factory Jimny coil springs and OME replacement coil springs. It is not a coilover unit , it requires separate coil springs as on the factory Jimny rear suspension.
What warranty covers the ARB63155?
The ARB63155 is covered by ARB’s 3-year warranty against manufacturing defects. Contact your ARB authorized dealer or ARB directly for warranty claim procedures.
