Innovative Mounts B-Series Shift Linkage for 88-91 Civic CRX

Innovative Mounts B-Series Shift Linkage | 88-91 Civic CRX

Drop a B16 or B18 into an EF and the engine mounts are only half the job: your stock D-series shift linkage no longer reaches the transmission it was built for. The Innovative Mounts B-Series Shift Linkage (59119) is the purpose-built answer for 1988-1991 Civic and CRX swaps, a bolt-on linkage made for the B-series gearbox instead of a hacked-up Integra linkage held together with hope.

What It Is and Why It Works

Innovative designed this linkage specifically for the ED/EE/EF chassis with a B16, B17, or B18 conversion. It's CAD/CAM designed and stress analyzed per Innovative, bolts in with all hardware included, and carries their lifetime warranty. At roughly 3 lbs per the manufacturer, it connects your stock shifter location to the B-series transmission with the correct geometry, so the shifter sits where Honda put it and finds gears the way a DC2 does.

The alternative everyone tries first is modifying a 90-93 Integra linkage: cutting, welding, and reusing 30-year-old bushings. It can work, but worn bushings and imperfect geometry are where vague, notchy shifting comes from, and chasing that after the swap is done means dropping the linkage again. A fresh purpose-built linkage costs about the same as the fabrication time it saves and shifts better than the salvage-yard route ever will.

Specs

Fitment

This is a swap part, not a stock replacement. Every trim of the 88-91 Civic and CRX left the factory with a D-series and will only need this linkage once a B16, B17, or B18 goes in. If your EF still runs its original engine, your stock linkage is the right part. Doing a K-swap instead? Different linkage entirely; this one is B-series only.

What to Know Before You Buy

Order this with your mount kit, not after. The linkage shows up in every EF B-swap parts list for a reason, and it's the part people forget until the engine is in and the car can't leave the garage. Pair it with Innovative's 88-91 B-series mount kit and the axles, and the drivetrain side of your swap is sorted in one order.

Two practical notes. Innovative doesn't accept returns once the part has been bolted down and shows bolt impressions, so dry-fit and confirm your combination before wrenching it home. And while you're under there, inspect your shifter bushings and shifter base; a new linkage feeding a sloppy 35-year-old shifter leaves shift quality on the table. If it were our car, we'd refresh the shifter bushings in the same afternoon.
