Redcat RER19473 vs RER32479: Which Part Fits Your Build?

These parts are not interchangeable

The RER19473 and RER32479 share a brand and a catalog page, but they solve different problems on different vehicles. RER19473 is a set of center differential cups listed for the MACHETE. RER32479 is Motor Mount B, listed for the VALKYRIE MT and VALKYRIE TR. Neither record lists the other's vehicle, so the first question is not which part is better—it is which vehicle you are repairing.

That makes this a fitment comparison rather than a performance one. The catalog gives you compatibility lists, part type, and package contents. It does not give dimensions, installation steps, or material specs for either part. Use the confirmed fitment to narrow your choice, then verify the rest against your own vehicle before ordering.

What the catalog confirms about each part

• RER19473: Genuine Redcat Racing replacement part; compatible with MACHETE vehicles; includes 2 center differential cups. The MACHETE compatibility note is the deciding fitment fact. The two-piece pack matters if you are servicing the drivetrain or keeping spares.

  

• RER32479: Motor Mount B, part number RER32479, listed for use with the VALKYRIE MT and VALKYRIE TR vehicles; includes 1 piece. This is a single motor mount for two VALKYRIE models. If you own a MACHETE, this part is not listed for your vehicle.

  

Side-by-side fitment check

Use this table to rule out the wrong part before you look at price or stock.

• Vehicle fitment: RER19473: MACHETE only, per the catalog. RER32479: VALKYRIE MT and VALKYRIE TR only, per the catalog.
• Part function: RER19473 is listed as center differential cups. RER32479 is listed as Motor Mount B. They sit in different systems, so one cannot substitute for the other.
• Quantity in the pack: RER19473 includes 2 center differential cups. RER32479 includes 1 Motor Mount B.
• Catalog price: RER19473 is listed at USD 8.44 (comparison price USD 12.99). RER32479 is listed at USD 11.09 (comparison price USD 14.99). Prices are catalog values and can change.

How to choose without guessing

The catalog does not provide installation instructions, torque values, or dimensional drawings for either part. That means your decision should rest on the vehicle you own and a visual check of the failed part, not on assumptions about interchangeability.

• Start with your chassis: If you run a MACHETE, RER19473 is the only one of the two listed for your vehicle. If you run a VALKYRIE MT or VALKYRIE TR, RER32479 is the listed option.
• Match the failed component: Confirm whether you are replacing center differential cups or a motor mount. The catalog names these as different part types, so the symptom should point to one system.
• Plan for spares: RER19473 arrives as a pair, which suits keeping a spare cup on hand. RER32479 arrives as a single motor mount, so consider whether one is enough for your repair.
• Check what is not stated: Neither record confirms material, dimensions, or install procedure. If you need those details, they are not in the supplied catalog information and should be confirmed separately before purchase.

The honest trade-off

There is no performance trade-off to weigh here because the parts do not compete for the same slot. The real trade-off is certainty versus convenience. Ordering the part listed for your vehicle is the straightforward path; ordering the other one because it is cheaper or in stock will not help if the fitment list does not include your chassis.

The catalog prices show RER19473 at USD 8.44 and RER32479 at USD 11.09, with comparison prices of USD 12.99 and USD 14.99 respectively. Treat those as catalog figures, not a reason to cross-shop. A part that does not fit is not a saving.

What to verify before you click buy

Check your model name against the compatibility line one more time: MACHETE for RER19473, VALKYRIE MT or VALKYRIE TR for RER32479. Then confirm the part type matches what you are replacing. If your vehicle is not on either list, neither part is confirmed for your build in the supplied information, and you should look for the part that names your model.

Because the records do not include installation guidance, plan your repair around the vehicle's own documentation rather than improvising from the part listing. That is the limit of what this comparison can tell you—and it is enough to keep you from ordering the wrong part.
