Description of Monroe 33178 Monro Matic Shock Absorber
1-3/16 inch Bore: Larger bore than most shocks to provide more efficient and consistent control. All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction. 1/2 inch Diameter Piston Rod: Nitro carburized rod for long service life. On non-dust shield units only. Made in United States.
I've never changed shock absorbers, but it was surprisingly easy , except I had to cut out an old one, on the roads here it's hard to tell if they offer a smoother ride, but the old ones were original (127,000 miles) and badly worn so replacing them was a good idea.
Pros
1/2" Piston Rod: Nitrocarburized rod for long life. Only on blocks without dust covers
Cons
I have no negative feelings about it, everything is fine
