Good replacement: Manifold

Excellent replacement part. I had to drill two holes in the center to fit, but my RV runs much quieter without a broken manifold.

Pros
  • Completely remanufactured - includes all necessary gaskets and downpipe fittings
Cons
  • Frequency

Product not as shown

Not as shown. Without seals and accessories. Just a collector. Not happy with this deal. Was a bit hesitant to buy auto parts through Revain. I will no longer buy parts here.

Pros
  • Ensure this part fits your vehicle, enter make, model and trim level into the service tool
Cons
  • . The list will be long.

Fits, but not perfectly

Purchased for a 1989 GMC Dual R3500.

The price was right and delivery was quick.

Pros
  • Rugged construction - heavy-duty materials resist warping, tearing and leaking for long life
Cons
  • Almost never

If you don't, you may find it difficult to fit spark plugs. Kit does not include manifold bolts (depending on engine you will need 8 on each side or 7…

Pros
  • Rugged design from the industry leader in aftermarket headers
Cons
  • No mold required
