If you want a durable, realistic aesthetic upgrade for your 1/10 scale RC crawler's spare tire, choose HooCrawler 1/10; if you need a complete set of replacement body posts to rebuild or stabilize your HSP model car chassis, choose Mjaie 4pcs. These two products serve entirely different mechanical and cosmetic functions within the hobby, and picking the wrong one leaves you with parts that simply do not fit your specific project needs. As an RV owner who treats my remote-controlled vehicles as mobile miniatures of real-world rigs, I understand that whether you are protecting a spare tire on a trail run or securing a body shell after a hard crash, the right component makes all the difference between a frustrating repair session and a smooth day out.
• HooCrawler 1/10: Offers a premium leather look designed to protect tires from dust and scratches while adding visual realism to crawlers like the TRX4 and SCX10, but it is strictly limited to a single spare tire application.
• Mjaie 4pcs: Provides a functional, four-piece kit of body post mounts essential for reattaching shells on HSP 94123 and 94122 models, though it lacks any cosmetic flair and serves only as a structural necessity.
• Who is this for?: Choose HooCrawler 1/10 if you prioritize style and tire protection on popular 1.9-inch wheel setups; choose Mjaie 4pcs if you have lost posts on your HSP chassis and need immediate restoration parts.
The HooCrawler 1/10 spare tire cover is built specifically for the enthusiast who cares deeply about the presentation of their rig. This product targets owners of popular 1/10 scale rock crawlers such as the Traxxas TRX4, D90, SCX10, FCX10, Capra, and GEN8. The core design philosophy here is realism. By covering the exposed metal or plastic of a spare tire with a material that mimics genuine leather, it transforms the vehicle from a toy into something that looks like a scaled-down off-road adventure machine.
Durability is another key factor for anyone taking their crawler off-road. The leather construction mentioned in the specifications suggests a material that can withstand abrasion better than simple rubber or plastic covers. When you are crawling over rocks, brushing against brush, or driving through dusty trails, a bare spare tire is vulnerable to scuffs and dirt accumulation. This cover acts as a shield, keeping the tire itself cleaner and preventing surface damage. The inclusion of three cool pattern options allows you to personalize the vehicle without compromising the rugged aesthetic, giving each build a distinct character.
However, this product is not for everyone. It is a single-unit accessory meant solely for the rear spare tire. If you are looking for general maintenance parts, interior upgrades, or components for a racing car rather than a slow-speed crawler, this will not help you. You should skip this item if you do not own one of the compatible brands listed, such as the TRX4 or SCX10, because the mounting geometry is too specific to be universal. It is a luxury addition focused on appearance and targeted protection, not a fundamental mechanical fix.

In stark contrast to the aesthetic focus of the HooCrawler, the Mjaie 4pcs kit is purely utilitarian. This product is designed for the practical problem of a broken or missing body post mount on a 1:10 scale model car. Specifically, it addresses the needs of owners of the HSP 94123 and 94122 models. In the world of radio-controlled cars, the body shell is held onto the chassis by small posts that screw into the frame. Over time, these posts can snap, get lost during transport, or wear out due to vibration and impact. Without them, the body shell rattles loose, flies off during high-speed runs, or fails to align correctly with the chassis, ruining the vehicle's aerodynamics and appearance.
The value of this set lies in its completeness. A full kit includes four pieces, which is the standard number required to secure a typical car body securely. The dimensions provided (0.39 x 1.57 x 1.18 inches) indicate a compact, medium-sized component designed to fit into tight chassis spaces without interfering with suspension movement or steering linkages. The multicolor designation suggests they may come with varied finishes or perhaps include the necessary screws and hardware, ensuring a direct replacement for the original factory parts. For the HSP 94123 and 94122 owner, this is not a "nice-to-have" item; it is a critical repair part that gets the car back on the track or trail.
This product is best suited for those who already have the chassis but lack the hardware to finish the assembly. It is not intended for upgrading the look of the car or adding new features. If you own a different brand of 1/10 car, such as a Traxxas or Arrma, these posts likely will not match the hole spacing or thread type. Similarly, if you are looking for a tire cover or suspension upgrade, this kit offers nothing in those categories. It is a niche solution for a very specific compatibility issue. If you are rebuilding an HSP model or trying to replace a lost post from a previous crash, this is exactly what you need to restore the structural integrity of your vehicle's body.

• Best for structural repair → Mjaie 4pcs, providing the essential mounts needed to hold a body shell onto an HSP chassis.

• Material durability → HooCrawler uses leather to resist dust and scratches; Mjaie uses standard materials for mechanical strength and fitment.
• Unit quantity → HooCrawler is a single unit for one tire; Mjaie is a 4-piece set designed to cover all mounting points.
• Installation complexity → Both require no tools, but HooCrawler adds style while Mjaie restores function.
• Use case scenario → Choose HooCrawler 1/10 for a weekend trail drive where appearance matters; choose Mjaie 4pcs immediately after losing a post during a crash.
• Long-term value → HooCrawler extends the life of the tire finish; Mjaie extends the life of the entire vehicle by preventing body loss.
I would buy the HooCrawler 1/10 for my own collection of crawler rigs. While both products solve problems, the HooCrawler offers a tangible improvement to the experience of owning an RC vehicle by enhancing its realism and protecting a vulnerable component. As an RV owner who appreciates details, seeing a well-maintained, stylish spare tire cover on my rig brings a level of satisfaction that a generic plastic part cannot match. However, if you are currently sitting on the floor with a disassembled HSP 94123 and a loose body shell, the Mjaie 4pcs becomes the obvious choice simply because it is the only thing that will get your car running again. For me, the choice comes down to preference for aesthetics versus necessity for repair, and I lean toward the piece that elevates the build.
The specifications list compatibility only for the HSP 94123 and 94122 Model Car Replacement Parts, implying they are engineered specifically for those chassis dimensions.
Yes, the product information states it features easy installation and removal with no tools required, suggesting it slips over the tire directly.
One is a cosmetic and protective cover for a spare tire on a crawler, while the other is a functional mechanical kit to secure a body shell on a specific model car.
