Skunk2 Alpha Rear Lower Control Arms 96-00 Civic EK

Skunk2 Alpha Rear Lower Control Arms 96-00 Civic EK

The rear lower control arms on your EK are pushing thirty years old, and they carry the lower shock mounts, so every bit of slop in those original rubber bushings goes straight into how the rear of the car behaves under load. The Skunk2 Alpha rear lower control arms for the 96-00 Civic replace the factory arms outright with forged aluminum pieces that firm up the rear end without turning a street car into a rattle box, which is precisely the design brief Skunk2 wrote for them.

What It Is and Why It Works

The Alpha arms borrow the generative design work from Skunk2's Ultra Series, then get forged from aircraft grade 6061 aluminum and fully CNC machined. Per Skunk2, that makes them 7 percent stronger and 15 percent lighter than the Pro Series arms they replace, the design half the aftermarket spent years copying. The material choice isn't arbitrary either: 6061-T6 carries a tensile strength over 42,000 psi with a fatigue strength rated for 500 million cycles, per manufacturer, which is the number that matters on a part that gets loaded and unloaded every bump for the rest of the car's life.

The smart part is the bushing strategy, because each of the arm's three joints gets a different answer. The trailing arm end runs a high precision spherical bearing, which stops the arm from twisting up the inboard bushing when you load the rear in a corner. The subframe end runs a large tuned durometer elastomeric bushing, firm enough to sharpen handling but compliant enough that the car doesn't get louder or harsher than stock. And the lower shock mount runs Delrin bushings, which cut friction and deflection so the damper responds to the road instead of to bushing squish. Skunk2 deliberately stopped at one spherical bearing per arm; they offer an inboard spherical as a racing upgrade, but the standard configuration keeps the street car livable.

Specs

Fitment

This part number is EK only. If you're on a 92-95 Civic, a CRX, or a DC2 Integra, Skunk2 makes an Alpha rear LCA for those chassis under a different part number, and the arms don't interchange. Grabbing the EK part for an EG is a guaranteed return trip, so check your chassis before checkout.

What to Know Before You Buy

Know what the spherical bearing means for daily life. One metal joint per arm transmits more road information than rubber ever did, and that's the point, but Skunk2 tuned this combination specifically so the total package doesn't get noisier or harsher than the factory arms. If you want maximum stiffness and don't care about comfort, the inboard spherical racing upgrade exists; if this is a street car, run the arms as they come.

Plan an alignment after the install. Any time the rear control arms come off an EK, rear toe and camber deserve a check, and if the car is lowered you probably need a rear camber kit anyway. Skunk2 positions these arms alongside their rear camber kit, lower arm bar, and strut tower bar for a reason: the arms fix compliance, the camber kit fixes geometry, and doing both in one session means paying for one alignment instead of two.

While the rear of the car is apart, look at what the arms bolt to. If the original shocks are tired or the trailing arm bushings are cracked, new arms will just point a brighter flashlight at the worn parts around them. The honest order of operations on a stock-bushing EK: shocks and springs first, then arms and camber kit together, then alignment. Do it in that order and the rear end comes out feeling like one decision instead of five patches.
