Frequently asked
Does it arrive assembled?
Yes — we assemble, calibrate and test-stitch it in Miami before shipping. To protect the machine during freight, the head ships detached from the table; remounting takes minutes and we can walk you through it by phone.
Can I finance it?
Yes. You can split your purchase into monthly payments with Affirm (checking your rate takes seconds and won't affect your credit score), and Synchrony offers special financing on qualifying purchases (subject to credit approval). See your options on the financing page.
Warranty & support?
Yes — on top of the manufacturer's warranty, Supra Sewing backs your machine with our own coverage: 90 days on mechanical defects and 12 months on electrical & electronic parts — and since this is a Speedway, your electrical & electronic parts are covered for 18 months, serviced by our in-house techs in Miami, FL. Support in English & Spanish: +1 (954) 681-3894 or WhatsApp.

Description
Description
The SPEEDWAY SW-4400-L18 is an industrial single-needle long-arm heavy-duty triple feed walking foot machine built for oversized, multi-layer projects that demand extended clearance and serious power. With an 18" arm, 6.5" height clearance, 900W belt-driven servo motor, and dual-tension mechanism for thick threads, it handles leather, canvas, upholstery, marine interiors, and industrial straps at up to 2,500 SPM — delivered fully assembled with table and stand.

Key Features
- 18" long arm + 6.5" height clearance — extended workspace for oversized upholstery panels, boat covers, automotive interiors, and large multi-layer assemblies
- Unison feed (walking foot) system — synchronized top and bottom feeding with rectangular feed mechanism prevents slipping on leather, vinyl, and heavy multi-layer materials

- Dual-tension mechanism — supports high-tension stitching with thick threads for maximum seam strength on the heaviest materials

- Max 9 mm stitch length — versatile stitch range for both functional and decorative heavy-duty applications
