Hasport B Series Swap Shift Linkage for 88-91 Civic/CRX

Hasport B Series Swap Shift Linkage for 1988–1991 Honda Civic and CRX

Dropping a B in your EF is easy to talk about and harder to do right. Everyone obsesses over the engine and mounts, then throws together a sketchy 88-91 CRX linkage and wonders why the car shifts like a tractor. The shift linkage is what actually connects you to that B-series, and if the geometry’s wrong, everything feels off. The Hasport 88-91 Civic shift linkage (SKU: HAS-EFBLINK) is built specifically for B-Series Civic linkage kit swaps into EF chassis cars that weren’t factory SiR. It fixes the geometry issues that come with putting a B-Series drivetrain into an EF that Honda never intended to take one, so your Hasport EF Honda linkage behaves like it belongs there. We run this same Hasport B Series shift linkage setup on our own EF cars because it just works.

Built Specifically for EF Chassis B-Series Swaps

 The EF Civic and CRX never came with a B in most markets, so once you throw in B-series mounts, the engine doesn’t sit exactly where the SiR motor did. That small difference is enough to screw up shifter angle and throw if you use the wrong Civic CRX B-Series linkage. Hasport starts with OEM 89–91 Civic SiR geometry, then tweaks it to match the engine placement you get with Hasport EFB1 and EFB2 mounts. The result: a B-Series EF shift linkage that keeps the rods at the right angles, clears the chassis, and moves through the gates without binding, guessing, or “is that third or fifth?” moments.

Key Features and Real-World Benefits

• Purpose-built performance shift linkage Civic kit for B-Series swaps in 1988–1991 Honda Civic and CRX
• Dialed to work with Hasport EFB1 and EFB2 B-Series mount kits on EF chassis
• Based on 1989–1991 Civic SiR geometry, corrected for non-SiR EF chassis and swap engine position
• CAD/CAM-developed layout for proper alignment and consistent, repeatable shift feel
• Gives you smooth, positive gear engagement instead of vague “hope this is the right gear” throws
• Eliminates the binding and misalignment you get with hacked, cut-and-welded linkages
• Built with long-term street and track use in mind, not just to get the car “working”

Why the Right Shift Linkage Matters on a B-Series EF

You can cobble together an EF chassis shift linkage from random parts. People do it all the time. Then they live with hard shifts, missed gears, sloppy play, and bushings that die in a season. That’s fine for a beater, but it’s miserable on a car you actually care about. The Hasport EF linkage set takes that guesswork out. Because it matches the geometry to Hasport’s B-series mount location, the shifter moves in clean, predictable paths. No weird side-loading, no “why does reverse feel closer than third,” and far less stress on joints and bushings compared to improvised CRX B Series linkage setups. If you daily the car, the consistency keeps it from feeling like a chore. If you track it, you can hammer gears without worrying the shifter’s going to fight you. We’ve trusted this exact Hasport CRX shift linkage on our own swap cars for that reason.

Vehicle Compatibility Notes

Compatible Vehicles:

• 1988–1991 Honda Civic EF chassis
• 1988–1991 Honda CRX EF chassis

Engine Compatibility:

• B-series engines using Hasport EFB1 or EFB2 mount kits

Not Compatible With:

• Non-Hasport mount kits (geometry won’t match)
• D-series or any non B-series engine setups
• EG, EK, or any non-EF chassis

If you’re not sure which mounts are on your car, confirm that first. Ordering CRX or Civic B-Series linkage without matching mounts is a good way to waste time and shipping money.

Installation Notes

With the correct Hasport mounts, this Hasport EF linkage set installs as a direct bolt-on. On a properly set up EF B-series swap, you shouldn’t need cutting or fabrication to fit this Hasport performance link kit. Final shift feel still depends on the condition of your shifter assembly and bushings. Worn rubber bushings or a sloppy shifter will hold back what this Hasport Civic shift linkage can do. For the tightest feel, Hasport recommends pairing it with solid or performance bushings and a good quality short shifter or fresh OEM shifter.

Recommended Complementary Parts

• Hybrid Racing Solid Shift Linkage Bushings HYB-SRB-01-10
• Hasport B-Series engine mount kit for EF Civic or CRX
• Quality short shifter or refreshed OEM shifter assembly

Made for Real Driving, Not Just Mock-Ups

 Whether your EF is a clean street car, a weekend autocross toy, or a budget track rat, this Hasport CRX shift linkage is built around correct geometry and repeatable performance, not flash. When the linkage actually matches your drivetrain layout, the rest of your mods can do their job, and your B-Series swap feels like it belongs in the chassis instead of fighting it.
