RER24205 vs 68066: Which Redcat Part Fits Your Build?

Quick Answer

RER24205 and 68066 are not interchangeable versions of the same part. They serve different positions and systems on a Redcat vehicle, so the correct choice depends on which assembly failed and what your manual lists for that spot. Check your vehicle documentation first. If the numbers do not match your parts diagram, neither part is the right buy.

Searching RER24205 vs 68066 usually means you have a broken or worn Redcat part and two numbers in front of you. That is a fitment question, not a performance question. Redcat uses distinct part numbers for distinct assemblies, and mixing them up costs time and return shipping.

This comparison walks through how to decide between these two numbers using your vehicle documentation, then shows how the same decision process works on other Redcat parts that are fully specified in the catalog.

Why RER24205 and 68066 Are Not a Simple Swap

Redcat part numbers identify a specific component, position, and often a specific vehicle family. Two numbers that look similar in format can belong to completely different systems, such as a drivetrain shaft versus a suspension mount. That means RER24205 vs 68066 is rarely a choice between two versions of one part.

The practical result is that you should not pick between them based on price or appearance. Pick based on what your vehicle's exploded diagram shows at the failure point. If the diagram calls for one number, the other number is not a substitute, even if it bolts near the same area.

• Find the failed part on your vehicle's parts diagram before comparing numbers.
• Match the full part number, not just the first few digits.
• If your manual lists neither number, stop and confirm fitment with the vehicle documentation.

What to Check Before You Order Either Number

Start with position. A front shock tower and a rear shock tower can look similar in a photo but mount at opposite ends of the vehicle and carry different loads. The same logic applies to driveshafts, hub carriers, and steering parts. Position is the first filter.

Next, check quantity and contents. Some Redcat parts ship as a single piece, some as a pair, and some as a full set with hardware. Ordering one piece when the job needs a pair leaves you mid-repair. The catalog listings for Redcat parts state the quantity, so read that line carefully.

• Confirm front or rear, left or right, and inner or outer position.
• Check whether the listing is one piece, a pair, or a set.
• Note whether hardware such as screws or spacers is included.

How to Compare Redcat Parts When the Catalog Is Clear

When a listing gives you full specifications, the decision gets much easier. Take RER22139, a rear shock tower sold as one piece. Its catalog facts name the position and the quantity, so you can confirm at a glance whether it matches the failed part on your diagram. No guessing about front versus rear.

The same applies to RER24103, a 51.5mm front center driveshaft sold as a one-set item and listed for use with the COE Custom Hauler. Length and vehicle fitment are both stated, which is exactly the information you need to avoid a wrong order. Use listings like these as your benchmark for what a complete part listing should tell you.

• Prefer listings that state position, dimensions, and quantity.
• Treat vehicle-specific fitment notes as the strongest signal.
• If a key spec is missing, treat it as a reason to verify, not to assume.

Small Parts That Decide the Repair

Not every comparison is between major assemblies. Fasteners and small hardware often determine whether a repair finishes cleanly. Product 50236 is a set of 6x18mm cap head machine thread screws, eight pieces, which is the kind of item that disappears into the carpet mid-job. Having a set on hand prevents a stalled rebuild.

Steering components matter the same way. R5607 is a steering links and bearing crush spacer set, sold as one set. If you are already replacing suspension or drivetrain parts, checking the steering linkage for play at the same time saves a second teardown later.

• Replace fasteners that show stripped or rounded heads.
• Inspect steering linkage whenever you have the front end apart.
• Buy sets rather than singles when the job consumes more than one piece.

Trade-Offs When Choosing Between Two Redcat Numbers

• Buying on price alone: A lower price is meaningless if the part does not fit your vehicle's diagram. The cheaper number can cost more once return shipping and downtime are counted. Verify fitment first, then compare price.
• Assuming similar numbers mean similar parts: Redcat part numbers are not sequential descriptions. Two close numbers can belong to unrelated systems, so format similarity tells you nothing about interchangeability. Match the full number against your documentation.
• Skipping quantity and contents: A single tower, a pair of hub carriers, and a full hardware set are different purchases. Ordering the wrong quantity leaves the repair half-finished. Read the quantity line before checkout.
• Ignoring missing specifications: When a listing does not state position, dimensions, or vehicle fitment, that gap is a decision limitation. It is a reason to verify, not a reason to assume the part works. Treat absent specs as a prompt to check the manual.

Redcat Parts With Clear Fitment Details

• RER22139: Shock Tower (Rear)(1pc) The listing states both position and quantity, so you can confirm rear fitment and know you are buying a single tower rather than a pair.
• RER24103: 51.5mm front center driveshaft, sold as a one-set item, listed for use with the COE Custom Hauler Length and vehicle fitment are both given, which removes the two most common reasons a drivetrain part gets returned.
• 50236: 6x18mm Cap Head Machine Thread Screws (8pcs) Eight screws in one set means you can replace damaged hardware during a rebuild without ordering singles.
• R5607: Steering Links and Bearing Crush Spacers (1set) A complete steering set lets you refresh linkage and spacers together instead of chasing individual pieces.

Which Number Should You Choose?

Choose based on your diagram

• Owners who have the failed part number from their vehicle's exploded diagram
• Buyers replacing a part whose position and quantity are clearly stated in the listing
• Anyone refreshing related hardware, such as R5607 steering links, during the same repair

Do not order yet if

• Your documentation lists neither number for the failure point
• The listing does not state position, dimensions, or quantity for the part you need
• You are guessing based on price or a similar-looking part number

RER24205 vs 68066 comes down to one question: which number does your vehicle's documentation list at the failed position? Answer that first, and the choice makes itself. When the catalog listing states position, dimensions, and quantity, as RER22139 and RER24103 do, ordering becomes straightforward. When it does not, verify before you buy.
