Right now we build trays for Subaru rockers, rocker arms, and shims for all 2014 and newer Subaru FA & FB Engines (FB20, FB2.5, FA20, FA25, FA24). Every slot is sized to the actual part, so nothing rolls, nothing mixes, and every piece goes back exactly where it came from. More engines are coming - and you can help us get there (see below).

Each tray is 3D printed in the USA from tough, oil-resistant polymer built for shop life. They'll survive brake cleaner overspray, greasy hands, and drops with ease.

Yes. Every slot has an embedded magnet strong enough to keep steel parts seated - tilt the tray, bump the bench, parts stay put. Be aware though, a drop to the floor will unseat the parts though.

Rockers and shims wear to their position. Reinstalling a shim in the wrong bucket, or flipping a rocker, means uneven wear and a comeback. Our trays are labeled and laid out to match the engine, so what comes off cylinder 3 intake goes back on cylinder 3 intake - same spot, same orientation.

That's the plan. If we don't cover your engine yet, send us your old rockers, shims, or lifters - we'll measure them, design the tray, and send you the first production units free.

US orders ship directly from our site. International customers: order through our Etsy shop, which handles VAT and import paperwork for you.LINK Coming Soon

Most orders ship within 2–3 business days depending on volume. My top priority is getting orders shipped as soon as humanly possible. We've grown accustomed to same or next day delivers from Amazon too so we get it - we want to get your order to you as quickly as we can, like we expect for ourselves. Either way, you'll get tracking the moment it leaves.

We make it right. If a tray shows up damaged, or your parts don't fit the way they should, contact us within 30 days and we'll replace it or refund you. No hoops.

We're a 2-man veteran-owned small business printing every tray in-house (literally in my house) in the USA. No overseas warehouse, no drop-shipping - the person who designed your tray also manufactured it and packed it. And most importantly, the person you almost certainly heard about this from is my son.

Yes. If you're outfitting a shop or buying for a team, reach out through the contact page and we'll put together a quote.

Wipe them down with soap and water or a shop rag. Avoid soaking them in solvents or running them through a hot parts washer (though this should be fine).
