PCI Honda Front Lower Arm Shock Spherical 2 Pc Kit

PCI Spherical Front Lower Control Arm Bearings - EF/EG/EK Civic, CRX, DA/DC Integra

Running coilovers on your EF, EG, EK, or Integra and your lower shock mount is wallowing out the rubber bushing? PCI makes spherical bearings that replace the rubber bushings in your front lower control arm where the shock bolts to it. The spherical bearings don't compress or deflect like rubber bushings do. That keeps your shock geometry consistent when you're cornering hard or hitting bumps. Your shock can move freely through its travel without binding, which means your damping actually works the way it's supposed to. If you're running stiff springs (over 10k lb/in) or you're tracking your car, spherical bearings are basically mandatory. Rubber bushings can't handle the forces and they tear or wallow out fast.

Here's Why Rubber Bushings Fail with Coilovers

Your factory lower control arm has rubber bushings where the shock bolts to it. Rubber bushings work fine with stock springs and shocks because the forces are low. But when you install coilovers with stiff springs (8k, 10k, 12k+ lb/in rates), the forces on those bushings go way up. Every time you hit a bump or you're cornering hard, the shock's trying to move and the rubber bushing's compressing and deflecting. That deflection changes your shock geometry and it prevents your shock from moving freely. The rubber also tears from the high forces. I've seen rubber bushings completely destroyed after one track day on stiff coilovers. Spherical bearings eliminate the deflection because they're solid metal with a bearing race inside. The shock can move freely without any binding or flex.

What Spherical Bearings Actually Do

Spherical bearings are metal housings with a ball-and-socket bearing race inside. The bearing allows the shock to pivot freely as your suspension moves through its travel. Unlike rubber bushings that compress and deflect under load, spherical bearings maintain precise geometry. That means your shock damping works consistently because the shock's not binding or fighting against a flexing bushing. You'll feel the difference immediately - the suspension feels more controlled and it reacts faster to inputs. Bumps get absorbed better and the car doesn't skip or hop over rough pavement like it does with worn rubber bushings.

Rebuildable - Not Throwaway Parts

PCI's spherical bearings are rebuildable. When the bearing race wears out after a few years of use, you can disassemble the bearing and replace the race instead of buying new bearings. Most cheap spherical bearings are sealed units that you throw away when they wear out. PCI's design saves you money long-term if you're actually using your car hard. The bearings come as a pair (left and right) for the front lower control arm shock mounting points.

Who Needs These and Who Doesn't

If you're running coilovers with spring rates over 8k lb/in or you're doing track days, you need spherical bearings. Rubber bushings won't last and they'll ruin your shock performance. If you're running stock suspension or mild lowering springs with stock-rate springs, you don't need these. Rubber bushings work fine for stock setups. Spherical bearings also add noise - they don't isolate vibration like rubber does, so you'll hear more road noise and clunking over bumps. That's the trade-off for precise geometry and no deflection.

Note: These bearings replace the rubber bushings at the lower shock mount on your front lower control arms. This is NOT the lower control arm bushing that connects the control arm to the chassis - this is specifically where the shock bolts to the control arm. You need a press or a ball joint press tool to remove the old rubber bushings and install the spherical bearings. Don't try to hammer them in - you'll damage the bearings. When you install spherical bearings, you lose some NVH (noise, vibration, harshness) isolation. You'll hear more road noise and clunking over bumps because metal bearings don't absorb vibration like rubber does. That's normal. If you want a quiet ride, don't install spherical bearings. These are for performance, not comfort. Check the bearings every 6-12 months and grease them if they have grease fittings. If they're sealed bearings, you can't grease them but you should still check for play or wear. Worn spherical bearings with excessive play will cause clunking and poor handling.
