Hardrace Rear Camber Kit (7670)

Product Overview

 Altering the ride height on multi-link rear suspension architectures skews the factory geometry, generating aggressive static negative camber. This reduction in the effective tire contact patch causes uneven tire wear, limits straight-line traction, and induces unpredictable handling transitions during high-load cornering maneuvers.

The Hardrace Rear Camber Kit (7670) is an engineered, heavy-duty adjustable replacement arm set designed to restore or customize rear axle tracking geometry. Available at JDMaster.net, this premium dual-arm kit features an integrated threaded adjustment turnbuckle system that enables precise, accessible camber tuning without removing the arm from the vehicle. Equipped with pre-installed, proprietary high-durometer hardened rubber bushings, this upgrade eliminates loose horizontal component tracking, ensuring immediate suspension response across the rear axle layout.

Key Features & Benefits

• Threaded Turnbuckle Camber Adjustment: Features a robust central adjustment collar that allows fine-tuned optimization of rear negative or positive camber parameters while mounted on the vehicle.

• High-Tensile Steel Alloy Tubing: Formed from cold-rolled structural steel to withstand intense compressive and tensile loads during aggressive track use or daily performance driving.

• Signature Premium Harden Rubber Bushings: Outfitted with solid, non-voided vulcanized rubber pivot points that eliminate horizontal bushing deflection while preserving necessary vertical travel compliance.

• Optimizes Rear Contact Footprint: Distributes load profiles evenly across the tire tread face, recovering optimal rear braking grip and accelerating mid-corner stability.

• Direct O.E. Structural Integration: Engineered to absolute dimensional tolerances to bolt directly into the vehicle’s original rear subframe and knuckle mounting points using factory hardware.

• Electrophoresis Deposition (ED) Coating: Treated with an advanced anti-corrosion chemical layer and topped with Hardrace performance blue paint to shrug off moisture, salt, and debris.

Technical Specifications

Applications

This specialized Part Number 7670 adjustable linkage set is precision-tailored for multi-link rear suspension architectures:

• Honda Accord 7th Gen (2003–2007 UC1 / CL7 / CL8 / CL9 / CM1 / CM2 / CM3 Chassis)

• Acura TL 3rd Gen (2004–2008 UA6 / UA7 Chassis)

The Mechanical Advantage: Stabilizing the Rear Roll Center

On advanced multi-link rear suspension assemblies, the upper control arm dictates the wheel’s arc of travel as the chassis pitches and rolls. Lowering the car forces this upper arm into an exaggerated upward slope, aggressively pulling the top of the wheel inward. Left uncorrected, the vehicle is forced to ride heavily on its inside tire edges, compromising stability and rendering standard factory tracking adjustments completely useless.

Standard factory rear upper links use highly compliant rubber bushings incorporating large void spaces. Under high lateral lateral g-forces, these soft bushings deform, causing the wheel assembly to wander dynamically between unplanned camber and toe variations. This structural play manifests to the driver as a vague, shifting sensation from the rear axle during mid-corner transitions.

The Hardrace 7670 Rear Camber Kit rectifies this behavioral deficit. By utilizing a heavy-duty threaded turnbuckle, alignment technicians can accurately adjust the arm length, pushing the wheel back into a stable vertical alignment profile. Because the solid-molded hardened rubber bushings resist horizontal compression, the rear wheels stay pinned exactly to their intended alignment targets under extreme loads, introducing predictable, linear handling tracking across the rear axle.

Professional Pre-Load & Alignment Integration at JDMaster

Get it Fitted by the Specialists: Performing upper link replacements on multi-link rear subframes requires careful mechanical execution. The inner mounting bolts must be tightened only when the vehicle’s suspension is fully settled at standard ride height under compression. Fastening these links while the suspension is hanging on a lift locks severe twist into the bushing material, causing the rubber to tear and fail long before its time.

Protect your investment by booking an installation appointment at the JDMaster.net workshop. Our factory-trained suspension specialists will execute the installation utilizing correct chassis pre-load techniques, inspect adjacent trailing arm assemblies for hidden fatigue, and perform a specialized 4-wheel alignment sweep calibrated to your exact street or track specifications.

Warranty

The warranty on Hardrace products depends on the type of product, with a minimum warranty period of 2 years. This warranty does not cover damage caused by a car crash, improper use, negligence or normal wear and tear.
