Hardrace Rear Lower Arm Harden Bushings – Civic (6103)

Product Overview

As golden-era Honda chassis rack up miles, the high-stress rear lower control arm (LCA) bushings suffer deep structural degradation, dry-rotting, and tearing. This material failure allows the rear lower arms to twist off-axis, causing vague mid-corner handling, snap oversteer tendencies, and unpredictable rear toe changes.

The Hardrace Rear Lower Arm Harden Bushings – Civic (6103) kit is a heavy-duty chassis restoration package engineered to lock down your rear axle geometry. Available at JDMaster.net, this premium 6-piece reinforced performance collection replaces your weathered factory rubber anchors with solid, high-durometer vulcanized hardened rubber bushings. By anchoring the rear lower arms firmly along their engineered axis, this kit stabilizes your alignment profiles without the harsh cabin vibration, binding, or constant maintenance required by aftermarket polyurethane alternatives.

Key Features & Benefits

• Signature High-Durometer Harden Rubber: Crafted from an ultra-dense, non-voided performance elastomeric compound engineered to maintain dimensional stability under extreme lateral G-forces.

• Arrests Dynamic Toe and Camber Deviation: Prevents the rear lower control arms from twisting under heavy load, keeping your rear tire contact patch stable through aggressive corners.

• Complete 6-Piece Rear LCA Refresh: Provides a total mechanical overhaul, replacing all three critical pivot bushings on both the left and right rear lower control arm assemblies.

• Improves High-Speed Cornering Stability: Substantially reduces body roll and side inclination during high-speed switchbacks, making the car track flat and predictably.

• Zero-Maintenance Operation: Formulated with premium synthetic matrix properties that require absolutely no regular lubrication, remaining completely silent and squeak-free over thousands of operational cycles.

• Direct OEM Replacement Fitting: Molded to precise CAD measurements with a 31.5mm body width profile to press cleanly into standard eyelet housings without modification.

Technical Specifications

Applications

This high-rigidity Part Number 6103 bushing set features specialized 31.5mm dimensions tailored specifically for fifth and sixth-generation Civic rear lower control arms utilizing standard fork-type shock mounting perches:

• Honda Civic 5th Gen (1992–1995 EG / EH / EJ Manual & Auto Models)

• Honda Civic 6th Gen (1996–2000 EK3 / EK4 / EJ6 / EJ7 / EJ8 / EJ9 / EM1 Manual & Auto Models)

• Honda Civic Del Sol (1992–1998 EG1 / EG2 / EH6 Chassis Variants)

• Acura / Honda Integra 3rd Gen (1994–2001 DC2 / DC4 / DB7 / DB8 Chassis Models — Note: Fits models requiring the narrower 31.5mm bush width profile; always measure your LCA eyelets before ordering as some Integra arms require the 50mm 6103-DC2 kit)

The Mechanical Advantage: Preserving Rear Axle Tracking Control

The independent rear double-wishbone architecture of classic Hondas owes its legendary handling potential to consistent control arm tracing during suspension travel. Under heavy cornering, the rear lower control arm acts as a primary load-bearing trace, managing lateral tire pressures and tracking trajectories. However, if that lower arm is anchored by soft or split original rubber bushings, a massive portion of your cornering force is wasted compressing the rubber flat inside its metal sleeve.

This structural deflection causes your rear toe and camber settings to drift wildly mid-corner, forcing the car to break traction unpredictably or suffer from vague turn-in feedback.

The Hardrace 6103 Harden Rubber Bushing Kit corrects this geometric vulnerability. Because the high-density performance rubber compound completely eliminates internal air voids, it resists physical distortion under extreme shear loads. The rear lower control arms are restricted to a stable, predictable vertical arc, allowing your performance coilovers, sway bars, and tires to work efficiently. The result is an instant upgrade in high-speed tracking control, immediate stability recovery, and flat, confident cornering.

Professional Hydraulic Press Installation at JDMaster

Get it Fitted by the Specialists: Extracting old, seized bushings from factory rear lower control arms requires dedicated hydraulic shop presses and precise backing sleeves. Attempting to hammer or torch these out can easily warp or bend the stamped-steel or aluminum control arm assembly, completely ruining its structural integrity and causing alignment bias.

Skip the safety hazards and schedule an installation slot at our JDMaster.net workshop. Our factory-trained suspension technicians will cleanly press out your weathered factory components, press-fit the new Hardrace units to exact depth specifications, and secure all mounting fasteners under natural ride-height pre-load to prevent premature bushing wear.

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.
