Hasport Performance K-Series Engine Mount Kit (01-05 Civic Non-Si)

Hasport Performance K Series Engine Mount Kit for 2001 to 2005 Civic non Si

If you want a real Civic 01-05 K-series manual swap in a non Si chassis, you already know the factory mounts are useless here. This Hasport engine mount kit is the swap mount kit Civic owners use to physically put a K series in the bay and keep the engine and trans where they belong, under load, at full lock, and over bumps. It locates the powertrain on the chassis and subframe so your axles and driveline geometry stay where they need to be, instead of doing the classic swap shuffle.

These are Civic 01-05 K-series mounts built around the swap, not a “close enough” combo of stock parts. You get swap specific brackets plus poly bushings, so you can control engine movement without pretending rubber mounts will magically behave. We run these exact parts on our own cars, and the tradeoff is simple, more control means more vibration. If you want Civic K-series vibration minimizing mounts, you pick the softer bushing. If you want the engine to stop trying to climb out of the bay on launches, you go stiffer and live with the buzz.

This page covers two versions, Hasport ESK3 K-series kit and ESK4, and the difference is the transmission family. Think of it like choosing between Civic RSX manual mounts geometry or Hasport TSX Accord engine mounts geometry. Your chassis can start life as manual or automatic, it doesn’t matter for fitment, but the 01-05 Hybrid is excluded.

• Vehicle compatibility: 2001 to 2005 Honda Civic non Si
• Chassis transmission compatibility: manual or automatic chassis
• Exclusions: 2001 to 2005 Civic Hybrid
• Required subframe for ESK3 and ESK4: RSX subframe or 2002 to 2005 Civic Si subframe. If you do not have that, stop here and plan the subframe first. Look at the Hasport CRV Element subframe kit options if you are mixing and matching parts across platforms.
• Transmission fitment, ESK3 version: 02 to 11 RSX and Civic Si manuals. This is the common Civic K-series manual swap direction and it pairs with the 02 to 11 RSX Civic Si transmission option.
• Transmission fitment, ESK4 version: 03 to 07 Accord and 04 to 08 TSX manuals. Choose this if you are using the Accord TSX manual family instead of the RSX Si style box.

Bushing stiffness selection and tradeoffs

Hasport 01-05 Civic mounts come in four durometers. Here’s the honest version. 62A feels the most street friendly, 70A is the common “I drive it hard” choice, 88A and 94A are for people who say “I don’t care” and mean it. Stiffer bushings reduce drivetrain rock, help keep shifts cleaner, and keep the header and exhaust from swinging into things. They also transmit more vibration at idle and low rpm, especially with big cams or solid exhaust hangers.

• Bushing options: 62A, 70A, 88A, 94A polyurethane

When you pick this kit

You buy this K-series Civic engine mounts setup when you want a known fitment path for a K swap in a 2001 to 2005 Civic non Si, you already committed to the correct RSX or Si subframe, and you know which transmission family you are running. It also makes sense when you want a defined poly mount option instead of guessing with mixed OEM parts. If you are cross shopping Hasport hybrid racing mounts or other Hasport manual transmission mounts, this one is the Hasport Civic K-series mount kit built specifically around the 01 to 05 Civic chassis and the required subframe.

Installation and planning considerations

Match the version to the transmission, match the subframe requirement, then choose your durometer based on how you actually drive your car. 62A helps if you care about daily comfort. 88A and 94A can make the car feel like it has a cell phone vibrating in the dash at idle, especially with a lightweight flywheel, but you get excellent movement control. Kit appearance can vary by version, and photos may show a different configuration than the one you order.
