Featuring an industry-leading independent front suspension for best-in-class ride and handling—plus Spartan RV Chassis’ extensive service and support network—you can confidently navigate any adventure that awaits.

You’ve worked hard and earned the ability to explore new places and meet new people on your time. We’re here to make sure your journey is safe, smooth, and always first class. The Jayco Embark is built exclusively on the Spartan RV Chassis’ K1 360 chassis. Designed, engineered, and made in America with the finest components creating a premier foundation for the most discerning RV makers and owners.

Spartan RV Chassis makes the only chassis built exclusively for motorhomes. We didn’t take the easy route and modify a truck chassis for our partners at Jayco. We knew they wanted an unmatched ride that was as smooth and quiet as it was invigorating and well appointed. So, we built them the unique K1 360 chassis from the ground up. The highest-quality materials provide reliability and dependability, and constant innovation means you’re safe & secure. Spartan RV Chassis provides a comfortable customer experience, nationwide service, and the best warranty in the business.
