22 SR bouncy ride

I own a 22 SR and ride is less than ok . I have 125k kms on it and the ride is almost sickening. Doesn't feel right . I have been in other tundra with higher packages that ride so smooth . I would like to stay stock height because I am old and short . Getting in the box is hard enough. If I buy shocks springs and struts for a Sr5 would it fix anything. Should 125k kms wear out my shocks ? I would love to go to bilstein but it doesn't show a replacement. Any assistance would be appreciated. This is my first tundra I have only owned silverado before .

 

That's about 77,000 miles. Did it always feel that way, or just start? I'd definitely be looking at shocks & struts.

 

I bought it used at about 90k kms and it's been same since I bought it. It doesn't bounce repeatedly like a worn shock but every pothole or dip in the road seems to send it off a bit . If I pass a car on the road and there is a dip it throws it around a bit . I think I will have to buy new shocks springs and struts
