Hardrace Harden Engine Mount Set – Honda Civic/Integra/RSX

Product Overview

On modern performance Honda layouts, the introduction of the K-Series engine brought immense power but also placed severe multi-axis load demands on the factory chassis mounts. The Hardrace Harden Engine Mount Set – Honda Civic/Integra/RSX is the ultimate comprehensive drivetrain optimization package designed to eliminate unwanted powertrain movement entirely.

This multi-piece master combo package replaces your worn, hyper-compliant factory mounting brackets with Hardrace’s signature high-density hardened rubber compound. By locking down the engine block and transmission casing simultaneously, this set prevents the entire powertrain assembly from twisting and pitching during aggressive launches, rapid high-RPM shifts, and extreme lateral track cornering—delivering pure, uninterrupted kinetic energy straight to the front wheels.

Key Features & Benefits

• Complete Engine Bay Optimization: Overhauls the critical side engine mounts, transmission brackets, and torque-arresting rear mount in a single, unified performance package.

• Controls Destructive Wheel Hop: Drastically restricts longitudinal engine pitch, keeping your front tires planted flat against the pavement during hard launches and low-gear corner exits.

• Signature High-Density Harden Rubber: Formulated to deliver track-day structural rigidity and massive load capacity without the harsh, cabin-shaking vibrations or interior rattles common to raw polyurethane.

• Prevents High-RPM Gear Lockouts: Keeps your mechanical shift cables and transmission selectors perfectly aligned under load, ensuring flawless, tactile gate entry up to the absolute limit.

• Protects Downpipes & Manifold Flanges: Drastically reduces the leverage forces exerted on your flexible exhaust joints, manifold studs, and turbocharger piping by containing engine torque.

• Direct Bolt-On CAD/CAM Design: Form-fitted to utilize exact original factory chassis mounting locations with zero drilling, cutting, or custom fabrications required.

Technical Specifications

Applications

Please match your exact chassis code and transmission layout before ordering. The Hardrace Harden Master Set line covers the following modern high-performance platforms:

• Honda Civic 7th Gen Type R / Si (2001–2005 EP3 / ES1) | Engineered to manage the unique packaging demands of the K20A2 / K20A powertrain, locking down the front subframe interface.

• Honda Integra 4th Gen Type R / Type S (2001–2006 DC5) | Direct-fit sets designed to withstand severe lateral G-loads on track, anchoring high-revving JDM Type R and local market specs.

• Acura RSX Base / Type-S (2002–2006 DC5) | The definitive upgrade to eliminate shifting inconsistencies and wheel deflection on premium K20A2 and K20Z1 street or track builds.

• Honda Civic 8th Gen Type R / Si (2006–2011 FD2 / FA5 / FG2) | Advanced multi-mount arrays developed to tame the intense longitudinal torque reaction of high-compression track setups.

The Mechanical Advantage: The K-Series Rotational Torque

The Honda K-Series engine rotates clockwise (unlike golden-era B-series engines) and relies heavily on a highly active torque-damping mounting layout. When you enter the VTEC crossover or engage in aggressive track downshifts, massive rotational forces try to twist the entire cylinder block inside the engine bay. Factory mounts utilize vast voided rubber spaces to isolate the cabin, allowing the engine to tip drastically off-axis. This structural compliance absorbs energy that should be accelerating the car, while physically pulling your gear selector linkages out of alignment.

The Hardrace Harden Master Set delivers a completely synchronized engineering solution. Because the entire engine and transmission move cleanly together as a single, controlled block, power is transferred instantly into the driveshafts. Best of all, because Hardrace utilizes an advanced solid rubber matrix rather than rigid plastic polyurethane inserts, it successfully filters out harsh engine harmonic frequencies—retaining an incredibly comfortable, civilized cabin environment for daily street driving.

Professional In-House Installation at the JDMaster Workshop

Leave the Heavy Lifting to the Specialists: Supporting the massive weight of a K-Series powertrain while unbolting old, oxidized subframe brackets, clearing tight timing-chain post positions, and setting rear firewall anchors can be an immense driveway challenge.

Save yourself the time and ensure total safety by booking a lift slot at our JDMaster.net workshop. Our master technicians will cleanly pull your factory brackets, position the complete Hardrace set, and torque every chassis fastener back to strict motorsport specifications to protect your axles and linkages.
