PCI Rear Trailing Arm Spherical Kit for 88-00 Civic/90-01 Integra

PCI Rear Trailing Arm Spherical Kit - EF, EG, EK, DA, DC 

Elevate how your 1988–2000 Civic, CRX, or Integra actually drives with the Pro Car Innovations (PCI) Rear Trailing Arm Spherical Kit (SKU: PCI-SB-TA-HONDA). This isn’t dress-up hardware — it’s the basis of a real Civic rear suspension upgrade or CRX rear suspension overhaul that fixes the geometry problems you get once you lower the car.

This PCI Civic rear arm kit / Integra rear arm set uses CNC machined 6061/2024 pieces paired with a spherical bearing to replace the factory rubber. That means way less suspension deflection, more consistent toe under load, and a rear end that does what you tell it to do instead of what the bushings feel like doing. We run this type of Civic CNC machined arm kit on our own cars for that exact reason.

On a lowered Civic, CRX, or Integra, toe curves usually go to hell. This kit corrects the toe link angles, which tightens up braking stability and mid-corner behavior. You’ll feel it most when you’re trail-braking or putting power down over bumps. With the extra control, you can get away with a Civic soft spring kit in the rear and still have the car feel planted instead of floaty.

If you’re building a CRX PCI trailing arm kit setup, Honda CRX trailing arm kit, or Honda Integra trailing arm kit track car, this is the Civic spherical trailing kit / Integra spherical arm kit that lets the alignment you dial in actually stay there. It also pairs well with Integra rear alignment correction parts and any PCI Integra rear arm upgrade you’re already running.

The assembly is fully rebuildable and built to handle real abuse, not just street cruising. PCI uses corrosion-resistant zinc-plated Grade 10.9 hardware, so it holds torque and laughs off weather and track grime. Maintenance is straightforward, and replacement pieces don’t require a full rework of your rear end.

Each arm carries a clean, laser-etched PCI logo — nothing flashy, just the important stuff. The kit integrates cleanly with OEM-style trailing arms and fits like you’d expect if you’ve done a few CRX suspension upgrade kit installs before. Just note: installing this Civic adjustable rear arm kit does require drilling for proper assembly, so have a drill, good bits, and basic fab sense ready.
