Honda Shock Tower Reinforcement Plate 74185-TGG-A00

Honda Shock Tower Reinforcement Plate 74185-TGG-A00 - Civic Si, Civic Type R & Accord

The top of your shock tower takes a beating you never see. Every bump, every hard corner, every time you load the front suspension, all of that force funnels up through the strut and into the upper strut mount, which bolts to a stamped section of the unibody. It's a small area carrying big, repeated loads, and over time that thin factory sheet metal around the mount is exactly the kind of spot that wants to flex and fatigue. This Honda reinforcement plate is the factory's answer. It's a stamped steel plate that sits at the upper strut mount and spreads that concentrated load across a wider area of the tower, stiffening the mount and backing up the metal that's working hardest.

Honda originally offered this piece on the FK8 Civic Type R, a car built to be driven hard, and it's since been proven to fit a range of other chassis. It's a genuine Honda part, so it fits and finishes like it belongs there, because it does.

What It Actually Does

By spreading the strut load over more of the tower, the plate reduces the localized flex right around the mounting studs. That means the strut's inputs translate into suspension movement a little more directly instead of getting partly soaked up by the tower deforming under load. On the street the effect is subtle, so be honest with yourself about expectations, but it firms up how solidly the suspension is anchored to the chassis and it helps protect that high-stress area from fatigue over the long haul. Think of it as reinforcing the foundation the strut bolts to.

A Cleaner Engine Bay

There's a reason people add this even on cars that didn't come with it. The plate dresses up the strut tower area with a clean, finished, stamped-steel look, and because it's a genuine Honda piece, it looks completely factory. It tidies up an otherwise plain corner of the engine bay without a trace of aftermarket fitment.

Camber Bolt Provision

The plate is designed with a provision for the camber adjustment bolt found on the Type R and Accord, so it clears that hardware and doesn't interfere with setting your front camber. On cars that don't use that bolt, the provision simply goes unused. Either way, you're not giving up any adjustment to run it.

Good to Know

A couple of honest points before you order. This plate reinforces the strut mount itself, which is a different job from a strut tower bar. A bar ties the two towers together across the engine bay; this plate strengthens the local metal at each mount. They complement each other, so if you're chasing maximum front-end rigidity you'd run both, not one instead of the other. Also, this plate is sold individually, so if you want to do both sides of the car, order two.
