Hardrace Rear 4-Link Arm Kit – Suzuki Jimny (Q0867)

Product Overview

While the JB64 and JB74 Jimny models are highly capable off the showroom floor, their factory rear radius-arm setup significantly limits wheel travel and vertical flex during heavy off-roading. When the vehicle is lifted, the rigid factory radius arms pull the rear axle forward and twist it unnaturally during suspension compression. This compromises tire contact with the ground, reduces traction over harsh terrain, and degrades high-speed on-road stability.

The Hardrace Rear 4-Link Arm Kit – Suzuki Jimny (Q0867) is an advanced suspension conversion system engineered to replace the factory radius arms with a high-flex, split upper-and-lower 4-link architecture. Available at JDMaster.net, this heavy-duty, fully adjustable 8-piece kit completely transforms the rear chassis dynamics. It allows the rear axle to move fluidly up and down through its travel stroke while maintaining a constant, optimal pinion angle. Equipped with a hybrid configuration of Hardrace’s signature hardened rubber and motorsport-grade pillow ball bushings, it delivers extreme wheel articulation over rocks and obstacles while significantly sharpening on-road handling and steering feedback.

Key Features & Benefits

• Complete 4-Link Suspension Conversion: Reconfigures the restrictive OEM radius arm layout into a true, separated upper and lower 4-link system to maximize vertical axle articulation and chassis flex.

• Constant Pinion Angle Control: Keeps the rear differential and driveshaft at a consistent, safe angle throughout the entire range of suspension travel, protecting your drivetrain from binding and premature universal-joint wear.

• Fully Adjustable Control Arms: Heavy-duty tubular steel arms feature fine-thread adjustability, allowing you to re-center the rear axle inside the wheel well and correct suspension geometry on lifted Jimnys.

• Ultra-Robust Construction: Includes ultra-thick 5.0mm high-strength steel alloy mounting brackets designed to withstand severe rock strikes, high-impact landings, and harsh off-road abuse.

• Hybrid Bushing Architecture: Pre-installed with a combination of hardened rubber and high-pivoting pillow ball joints to absorb road noise while offering vastly superior twisting angles and response over soft factory rubber bushings.

• Anti-Corrosion ED Coating: Every component undergoes an advanced Electro-Deposition (ED) coating process followed by a highly durable protective paint coat to defend against rust, mud, and road salt.

• Direct Bolt-On Integration: Engineered as a complete, direct-fit upgrade. The kit utilizes clever mounting points to install seamlessly onto the chassis without requiring structural cutting, drilling, or welding.

The Mechanical Advantage: Radius Arm vs. True 4-Link Articulation

The factory Suzuki Jimny suspension relies on a 3-link setup with dual radius arms holding the solid axle in place. While cost-effective and predictable for everyday street driving, radius arms act as giant levers that force the axle to move in a rigid arc. When one rear wheel drops into a deep rut and the opposite wheel compresses over a rock, the axle is forced to twist inside the radius arm mounts. This creates massive structural binding, strains your suspension bushings, and prematurely limits how far down your tires can drop to search for traction.

The Hardrace Q0867 4-Link Kit completely resolves this engineering hurdle by splitting the single mounting points into separate, triangulated upper and lower control arms. This layout decouples the axle’s vertical travel from its rotational twist.

When climbing vertical ledges or traversing deep ruts, the separated links allow the axle to rotate independently on its lateral axis. This delivers massive suspension flex, keeping all four tires firmly planted on the ground for maximum traction. Furthermore, because the kit is fully adjustable, it eliminates the rear-axle shifting common on vehicles with suspension lifts, keeping your rear wheels track-aligned perfectly behind the front wheels.
