RER24205 vs 180007: Redcat Part Comparison

Quick Answer

RER24205 and 180007 are not interchangeable, so the right choice depends on what your vehicle actually needs. If you are replacing a failed housing or drivetrain component, RER24205 is the one to check first; if you are chasing a battery fit or mounting issue, 180007 is the better starting point. Match the part number to your model's exploded view before ordering, and never buy on price alone.

If you have been searching for rer24205 vs 180007, you have probably noticed these two numbers show up in the same conversations but rarely in the same sentence. That is because they are not competing versions of the same part. They sit in different areas of a Redcat vehicle, and treating them as a straight swap is the fastest way to waste money and bench time.

This comparison breaks down what each part number actually is, where it lives on the car, and the trade-off you are really making when you choose one over the other. The goal is not to crown a winner. It is to help you read your own repair situation clearly so you order the rc replacement parts you need the first time.

What RER24205 Actually Is

RER24205 is a gearbox housing set. That places it in the drivetrain, where it holds internal gears in alignment and protects them from dirt and impact. If your vehicle has a cracked housing, a stripped mounting ear, or a gearbox that will not hold its mesh, this is the part you inspect first. It is a structural component, not a tuning part, so it does not change how the car drives when it is healthy.

Because it is a housing, the fit is specific. You are not choosing it for performance gains; you are choosing it because the original failed or because you are rebuilding a damaged section. That makes the decision simple: check your model's parts diagram, confirm the housing shape matches, and replace it when the old one is compromised.

• Inspect for cracks around screw holes and bearing seats before assuming a gear problem.
• Replace the housing if any mounting point is stripped; thread repair on plastic rarely holds.

What 180007 Actually Is

180007 is a battery tray. It sits in the chassis and holds the pack in place, which makes it a fit-and-retention part rather than a drivetrain part. If your battery slides under acceleration, if the tray has cracked at the strap mounts, or if you are changing pack size and need a secure hold, this is the number you look at. It affects how the car behaves only indirectly, by keeping weight where it belongs.

The trade-off here is different from the gearbox housing. A battery tray is cheap insurance against a pack ejecting mid-run, but it will not fix a drivetrain noise or a handling complaint. If your issue is mechanical rather than retention, 180007 is the wrong purchase no matter how good the price looks.

• Check tray cracks at the strap anchors; a tray that flexes will let the pack shift.
• Confirm your pack dimensions before ordering any tray, since fit varies by model.

Why They Are Not Interchangeable

The core of this redcat part comparison is that these two numbers solve different problems. One is a drivetrain housing, the other is a chassis retention part. You cannot substitute one for the other, and you should not try to decide between them based on which is cheaper. The correct question is which system on your vehicle is actually failing.

That is also why forum threads that pit rer24205 or 180007 against each other often go nowhere. The people asking usually have not identified the failure yet. Diagnose first: is the symptom a noise or loss of drive, or is it a battery that moves? That single answer eliminates one of the two parts immediately.

• Noise or loss of drive points toward drivetrain parts like RER24205.
• A shifting or ejecting battery points toward tray parts like 180007.

Other Redcat Parts Worth Checking While You Are In There

If you are already tearing into the gearbox area, it is worth inspecting the surrounding structure. The RER14730 gearbox housing set and the RER14735 rear axle housing are both housing-type parts that live in the same general region, and they can wear or crack from the same impacts that damage a gearbox housing. Replacing a failed housing while a cracked neighbor stays in place usually means doing the job twice.

On the chassis side, the RER43525 bumper set protects the front and rear of the vehicle and takes the hits that would otherwise reach the tray and housing mounts. The RER23603 frame rail mount set is another plastic structural part that can crack in a hard landing. None of these are upgrades in the performance sense, but they are the parts that keep the rest of the car straight.

• Order housing and mount parts together if the car has had a hard impact.
• Check bumper and frame mounts before blaming electronics for intermittent faults.

How to Decide Without Guessing

Start with the symptom, then match it to a system, then match the system to a part number. If the car loses drive or makes grinding noises under load, inspect the drivetrain and look at RER24205 and its neighbors. If the car runs fine but the pack moves, inspect the tray and look at 180007. This order prevents the most common mistake in rc car parts buying, which is ordering by part number before confirming the failure.

One more practical note: keep a small stock of the cheap structural parts. A battery tray or a bumper set costs little compared with a race weekend cut short, and having one on the shelf means a cracked part does not end your session. Buy the part you need now, and note the part you will likely need next.

• Photograph the failed area before ordering so you can compare it to the diagram.
• Write the part number on the old component when you remove it for future reference.

Trade-Offs at a Glance

• Problem type: RER24205 addresses drivetrain housing failures; 180007 addresses battery retention. These are different systems, so the trade-off is which failure you actually have. Diagnose the symptom before choosing a part number.
• Cost of guessing wrong: Buying the wrong part wastes money and leaves the real fault in place. A gearbox noise will not be fixed by a new tray, and a sliding pack will not be fixed by a housing. Match the part to the system, not to the price.
• Stocking strategy: Structural plastic parts like trays, bumpers, and mounts are cheap to keep on hand and fail from impacts. Keeping spares shortens downtime more than keeping drivetrain spares. Stock the cheap impact parts; order drivetrain parts as needed.

Product Facts

• RER14730: Gearbox Housing (1 set) If you are already replacing a gearbox housing, this is the direct catalog match to check against your model's diagram before ordering.
• RER14735: Rear Axle Housing (1set) A rear axle housing in the same drivetrain region can crack from the same impacts, so inspect it while the gearbox is apart.
• 61006: Battery Tray (1pc) A battery tray is the retention part that keeps the pack from shifting, which is the problem 180007 addresses.
• RER43525: Bumper Set (F/R)(10W)(1pr) Bumpers absorb the impacts that would otherwise reach housings and mounts, making them cheap protection for the parts above.

Which One Fits Your Build

Best for

• Drivers diagnosing a drivetrain noise, loss of drive, or cracked gearbox housing
• Builders rebuilding a damaged section who need a specific housing or tray part

Not for

• Anyone hoping to swap one part for the other; they are not interchangeable
• Shoppers choosing by price alone without confirming the failed system

RER24205 and 180007 are not rivals; they are answers to two different questions. Identify whether your vehicle has a drivetrain failure or a battery retention problem, confirm the part number against your model's diagram, and buy the one that matches. That single step saves more time and money than any comparison chart.
