JRide Plus Package: Bilstein shocks, stabilizer bar, Hellwig helper springs and rubber isolation body mounts.
I'm suspect that they really aren't providing much suspension upgrade.
The shocks are an upgrade but Koni shocks would be more desirable. Did they upgrade "the" stabilizer bar or are they just stating that it has what Ford shipped it with? Many people upgrade front and rear stabilizer bars but Jayco only mentions one. Helper springs may or may not suggest that the chassis has no reserve weight capacity. I'd prefer air bags instead of additional springs because of the adjustability. Rubber body mounts are not unique to Jayco. I'm suspect that they really aren't providing much suspension upgrade.
