We’re welding these daily, but depending on demand, they can take up to 2 weeks to ship. Get your order in early and lock in your spot—we’ll handle the sparks.

This is how you do it. The cleanest, most dialed way to hardtail your ’66–’84 Shovelhead swingarm frame—no weird stretches, no chopped-up geometry, no guessing games. Just a proper Panhead-style tail section that bolts in smooth and keeps your VIN right where it belongs.

Fits like it should—because we built it that way.

This setup runs replica cast axle plates and a cast seat post yoke, just like the factory used to do it. Rear trans posts are threaded, the lines stay lean, and everything is TIG welded in-house in Northern California. You even get slugs for the lower rails. It's all there, ready to roll.

No frame jig? No stress. You won’t need one. This kit is designed to go in easy and lock up tight—so you can get back to building instead of wrestling with the welder.

Why it rules:

• OG Panhead-style geometry—no stretch, no rise, no drama
• Replica cast axle plates + seat post yoke made by HCI in the PNW
• Fully TIG welded + assembled in Northern California
• Slugged top tube for a clean graft
• 1-1/8" DOM lower rails match stock frame tubing
• Chain clearance built in with a subtle kick-out on the drive side
• Designed to preserve your factory VIN—so the DMV stays outta your business

What's in the box:

• Weld-on hardtail section
• (2) Bottom rail slugs
• (1) Rear transmission weld-on support

Fitment:

• Fits factory Harley-Davidson swingarm frames from 1966–1984

• Meant for kick-only setups with an open belt drive
• Running a starter? You may need to check clearance on early horseshoe tanks

Install Tips:

You’ll need to cut out the stock seat post area and graft in the new section. Our top tube is pre-bent, slugged, and ready to slide in just ahead of the original seat post casting. The rails taper like a Panhead for that narrow, vintage silhouette. Everything’s sized and shaped to match stock tubing—no weird fitment or steps.

Check out our cutting diagrams in the photos to get a clear look at where and how to trim your frame. This one’s all about keeping it classic and making your life easier.
