Weber Spirit E-425 vs E-425C
The C is four swivel casters instead of two wheels, for $20. The cookbox, the fire and the grate are identical. Which one to buy, and when the cart matters.
We pick the Weber Spirit E-425 Gas Grill
Buy the E-425 and keep the $20, unless the grill has to move. Every figure above the cart is the same on both: 35,000 BTU across four stainless burners, 428 sq in of primary grate, 82 BTU per square inch, 103 pounds. What the letter buys is four swivel casters in place of two wheels and two fixed feet, plus an inch less depth with the lid down.
What actually differs
-
The cart, and nothing above it
Weber publishes the same burner output, the same primary and total grate, the same weight and the same cast-aluminium cookbox for both. The E-425C changes how it rolls and nothing about how it cooks.
-
Four swivel corners against two wheels
The E-425 pivots on two wheels and drags two fixed feet; the C steers in any direction and locks two of its four casters. On a tight patio or in and out of a garage that is a real difference, and on a slab it never leaves it is none.
-
The part you paid extra for has the shortest warranty
Ten years reaches the cookbox and the burner tubes on both grills. The casters sit in the two-year tier along with the paint, so the upgrade is the component least covered.

Both reviews are scored on the same six weighted categories, on the same 0 to 10 scale, and each reason is the one that review gave. A category is marked better only where the two differ by a tenth or more. How we score →
Heat density
Burner output over the surface it has to heat, derived in each review from that cooker's own published figures. A bigger number is not a better grill. It says how hard the cooker can drive its grate, nothing more. All grills ranked →
Where the spec sheets differ
Quoted from each maker's own specifications, as each review records them. Figures the two products publish identically are left out, so only the differences are listed.
Which one is for you
You move the grill often: a narrow patio, winter storage, or a surface you have to steer across.

Every score and figure on this page comes from our own reviews of these two products, linked above. We have not tested them side by side in one place; the comparison is between two full reviews, each built from the maker's published specifications and documentation. Prices move, and the ones quoted are the ones each review checked on its own date.
