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

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

Drop a B16A or B18C into an EF and the mounts are only half the job. Your stock D15 or D16 shift linkage no longer reaches the transmission it was built for, and the car will not leave the garage until something bridges that gap. The Innovative Mounts B-Series Shift Linkage (59119) is a purpose-built B-series shift linkage for the 1988-1991 Civic and CRX, a bolt-on unit made for the B-series gearbox instead of a cut-and-welded Integra linkage held together with hope.

What It Is and Why It Works

Innovative built this linkage specifically for the ED, EE, and EF chassis running a B16, B17, or B18 conversion. It is CAD/CAM designed and stress analyzed per Innovative, bolts in with all hardware in the box, weighs 3 lbs, and carries their lifetime warranty. It connects your factory shifter position to the B-series transmission with the geometry already worked out, so the shifter sits where Honda put it and finds gears the way a DC2 does instead of the way a homemade rod does.

The alternative everybody tries first is a 90-93 Integra linkage, cut down, welded, and reused with thirty-five-year-old bushings. It can work. It also has to come back out when the shifting turns vague, because worn bushings and imperfect rod geometry are exactly where notchy, wandering gate feel comes from. Chasing that after the swap is buttoned up means dropping the linkage a second time. A purpose-built B-series shift linkage costs about what the fabrication time is worth and shifts better than the junkyard route ever will. If you are running a B20B block, you are still behind a B-series gearbox, so the same linkage applies.

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 only needs 59119 once a B-series goes in, whether that is an EF8 CRX Si that started life with a D16A6 or a base hatch that came with a D15. If your EF still runs its original engine, your stock linkage is the correct part and this one will not help. Doing a K-swap instead? Completely different linkage. This one is B-series only.

What to Know Before You Buy

Order this with your mount kit, not after it. The linkage appears on every EF B-swap parts list for a reason, and it is the piece people forget until the engine is bolted in and the shifter reaches nothing. Buy it alongside the 88-91 B-series mount kit and a set of 90-93 Integra axles and the drivetrain side of the swap arrives in one shipment.

Two practical notes. Innovative will not accept a return once the part has been bolted down and shows bolt impressions, so dry-fit and confirm your transmission and mount combination before you torque anything. And while you are under the car, look hard at your shifter bushings and shifter base. A fresh linkage feeding a worn-out shifter assembly leaves most of the improvement on the table, and those bushings are thirty-five years old whether the car looks clean or not. If it were our car, we would replace them in the same afternoon and only crawl under there once.
