2008 Itasca Suncruiser 33V

Suncruiser has a w-22 chassis

I just replaced the front shocks on my 2005 Winnebago Voyage 33V (W-20 Chassis). Original shocks were Bilsteins. Replaced them with the new Bilstein shock which has a much improved valving system. The improvement in the ride was significant. Probably the best money we have spent on the motorhome. No more bone jarring jolts when you hit expansion joints and rough roads.

Workhorse W or P chassis.

Easy to tell:

P chassis front suspension is independent-- looks like a Chevy truck.

W chassis has solid front axle.

So suspension upgrades are VERY different.

Also, have you had the wheel positions (best) or axles weighed?

Have you set your tire pressures based on your tire manufacturer's recommendations for that actual weight-- if individual wheel weights, use the heavier wheel position to go to your tire manufacturers PSI table. If, for example you are 20 PSI overinflated, you ride will be terrible.

What chassis-- suspension upgrades are chassis-related.
