Hey Ronald, for your 2021 Jayco Greyhawk 27U that is built on a Ford E-450 Class C chassis the Hellwig front sway bar part # HE26GR is a confirmed and would be a great option to improve the handling of your motorhome. I am sorry it's not listed in a better way in our fitguide to have made it easier for you to confirm but I can confirm it will be what you'd need. What is the handling like on your Greyhawk currently?

I installed mine on a 2020 Jayco Redhawk 24B. Along with a roadmaster steering stabilizer and a beefed up Hellwig sway bar in back it’s like driving a Cadillac.

I added the Hellwig front sway bar and Safe-T-Plus steering stabilizer at the same time. I was even able to do the install myself. The difference is amazing. Wind on any road, and uneven narrow roads even without wind used to be a nightmare. I would never go back to driving another class-C until it had similar upgrades.
