Hardrace Rear Stabilizer Bushing – Honda Integra/Civic

Hardrace Rear Stabilizer Bushing – Honda Integra/Civic (7450)

Product Overview

Your vehicle’s rear stabilizer bar (anti-roll bar) is tasked with managing lateral chassis load transfer during hard cornering maneuvers. However, original factory D-bushings are composed of highly compliant rubber that distorts easily under stress. This structural compliance creates an unwanted cushioning effect, delaying rear sway bar engagement and allowing the rear track alignment to wander off its intended line.

The Hardrace Rear Stabilizer Bushing – Honda Integra/Civic (7450) kit is a high-performance structural solution engineered to eliminate this mechanical elasticity. Available at JDMaster.net, these uprated bushings anchor the rear sway bar firmly against your subframe or reinforced mounting brackets. By neutralizing physical deformation, this kit ensures that lateral body roll translates immediately into torsional bar resistance—delivering flat cornering profiles and sharp, predictable chassis rotation.

Key Features & Benefits

• 22mm Precision Bore Sizing: Custom-contoured with a precise 22mm inner diameter, engineered explicitly to match standard high-performance factory anti-roll bars.

• Advanced Thermoplastic Matrix Formulation: Manufactured from an industrial-grade, non-voided thermoplastic compound. This specialized material matches the structural stiffness of hard plastics while retaining the fluid elasticity of rubber to prevent structural binding.

• Arrests Dynamic Alignment Deviation: Prevents the rear sway bar from moving off-axis inside its mounting brackets, preserving a constant tire contact patch across your rear independent suspension layout.

• Self-Lubricating Internal Bore: Features a low-friction chemical composition that allows the stabilizer bar to rotate smoothly through its vertical sweep without squeaking, completely eliminating the constant maintenance and greasing required by standard polyurethane alternatives.

• Anti-Crack Structural Longevity: Highly resilient material engineering that will not split, crumble, or experience permanent structural compression under continuous high-load track usage.

• Total Environmental Insulation: 100% resistant to structural breakdown caused by road salt, ambient moisture, under-carriage grime, engine oil, and extreme exhaust system radiant heat.

• Direct Press-Fit OEM Dimensions: Precision-molded to factory CAD profiles to slip seamlessly into original rear D-brackets or compatible heavy-duty aftermarket subframe reinforcement clamps.

Technical Specifications

Applications

This specific Part Number 7450 high-rigidity thermoplastic rear bushing set is engineered exclusively for 22mm rear stabilizer bar configurations found on modern multi-link and independent rear suspension layouts:

• Honda Integra Type R 4th Gen (2001–2006 DC5 Chassis with K20A Engine)

• Honda Civic Type R 7th Gen (2001–2005 EP3 Chassis with K20A Engine)

The Mechanical Advantage: Instantaneous Rear Rotation

Modern front-wheel-drive Honda architectures depend heavily on a rigid rear suspension setup to counteract natural low-speed understeer. When you guide your vehicle into a corner, lateral weight transfer instantly tries to compress the outer rear tire. A high-durometer rear sway bar works by pulling downward on the inner control arm, leveling the chassis and encouraging the frontend to bite into the pavement.

However, if that rear sway bar is resting inside soft, worn rubber bushings, a major percentage of that cornering energy is wasted compressing the rubber flat inside the metal bracket. This material compression results in a sluggish transitional feel, where the rear axle slips into an unpredicted deflection state before stabilizing.

The Hardrace 7450 Thermoplastic Bushings provide a zero-play foundation. Because the material does not distort under compressive load spikes, your rear anti-roll system functions at maximum mechanical efficiency. Body roll is checked instantly at the turn-in point, giving you predictable rear rotation and the confidence to extract maximum speed through the corner.

Professional Subframe Access & Installation at JDMaster

Get it Fitted by the Specialists: While changing rear stabilizer bushings appears straightforward, rear subframe sheet metal tabs are notoriously thin and prone to stripping when exposed to high-torque impact tools. Furthermore, mounting brackets must be torqued symmetrically to prevent the bar from binding off-axis, which can induce severe pre-load handling biases.

Protect your chassis hardware and schedule a lift slot at our advanced JDMaster.net workshop. Our factory-trained suspension technicians will inspect your rear anti-roll bar links, line up your new Hardrace thermoplastic units with clean seating alignment, and torque every fastener to factory specifications while the chassis is fully loaded at ride height.

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.
