If you want a comprehensive, heavy-duty replacement set for a daily driver SUV like the 2015-2016 CR-V, choose sherxibo Motor Mount Kit; if you need a precise, lightweight solution for high-performance European tuning on a CLA45 or GLA45, choose loongrie Engine Motor Transmission.
This decision isn't about which brand is more famous or which one has better marketing; it comes down to the specific mechanical demands of your vehicle and how you plan to use it. The automotive world often forces buyers into a false dichotomy between "cheap" and "expensive," but when you are dealing with critical engine mounting hardware, the real differentiator is fitment scope and load capacity. For track days, where the engine experiences violent lateral G-forces and rapid torque reversals, the difference between a standard OEM-style replacement and a performance-oriented mount kit can mean the difference between a smooth lap and a broken bracket. I have analyzed the specifications of both options to help you decide which path aligns with your driving style and vehicle platform.
• The sherxibo pick is for the owner of a family SUV who needs a reliable, all-encompassing fix to silence rattles and stabilize the powertrain after years of wear.
• The loongrie pick is for the enthusiast running a modified Mercedes CLA45 or GLA45 who requires a direct OE replacement that fits tight tolerances without adding unnecessary mass to the front end.
The sherxibo Motor Mount Kit is built as a total solution rather than a single-part fix. Looking at the data, this kit includes five distinct components: a front motor mount, a right motor mount, a rear lower torque strut mount, a right upper torque strut mount, and a left transmission mount. This level of completeness is rare in aftermarket offerings, where many sellers only provide the primary engine mount while leaving the torque struts to fail later. For a 2015-2016 CR-V 2.4L, the drivetrain relies heavily on these interconnected mounts to manage the vibration and movement of the engine block. If you are planning a track day or simply driving aggressively on twisty roads, having all five points secured ensures the engine doesn't shift excessively under hard acceleration or braking.
In the context of a compact crossover like the CR-V, this weight indicates robust materials designed to absorb significant shock and hold the engine firmly in place against the chassis. This is not a product for someone looking to shave ounces off their vehicle's unsprung weight for a drag race; it is a product for someone who wants the engine to feel planted and quiet during everyday driving, even when pushing the car harder than usual. The inclusion of multiple torque strut replacements is particularly valuable because these struts often wear out faster than the main engine mounts, leading to that dreaded clunking sound when shifting gears.

You should buy this kit if your Honda CR-V is showing signs of general drivetrain slop, excessive noise, or if you are performing preventative maintenance before hitting the weekend road course. The kit covers every major mounting point listed in the compatibility data, replacing OE numbers like A65081, A65053, and A65070. However, if you own a Mercedes-Benz CLA45, this kit is useless regardless of how good the quality might be. It is strictly for the 2.4L Honda engine bay, and trying to force it elsewhere would be a waste of time and money.
The loongrie Engine Motor Transmission kit takes a completely different approach by focusing on precision and performance for the Mercedes-Benz lineup. This kit is a three-piece set specifically calibrated for the 2.0L L4 engines found in the CLA45 AMG, CLA250, B250, and GLA45/GLA250 models from 2013 through 2020. Unlike the sherxibo option, which aims for total coverage, the loongrie kit targets the specific high-stress areas required by these German engineering platforms. This low mass is intentional; high-performance vehicles benefit from reduced rotating and reciprocating mass, allowing the engine to rev more freely and react quicker to throttle inputs.
The specification sheet mentions that the manufacturer uses advanced laboratory equipment to test their products, aiming to surpass OE brackets. While we cannot verify independent lab results, the emphasis on raw material quality and the specific OE number cross-references (A4076, A4050, A4049) suggest a focus on exact fitment for the tight tolerances of an AMG or Mercedes performance model. These cars generate significant torque, and the mounts must handle that power without flexing too much, yet they also need to isolate high-frequency vibrations. The loongrie kit appears designed to strike that balance, offering a direct replacement that maintains the intended driving dynamics of the CLA or GLA.
This product is ideal for the track-day enthusiast who runs their Mercedes on the circuit. When you are launching a turbocharged four-cylinder at 6,000 RPM, you need mounts that won't break under stress but also won't introduce unwanted slack that could damage other components. The loongrie kit provides the necessary stability for the CLA45 or GLA45 without the bulk of a full-suspension overhaul. However, if you drive a non-performance variant or a different brand entirely, this kit will not fit. It is a specialized tool for a very specific job, perfect for keeping your AMG humming smoothly but irrelevant if you drive a Ford F-150 or a Toyota Camry.
• Best for Total Coverage → sherxibo Motor Mount Kit, as it includes five separate components covering front, rear, and transmission points, whereas loongrie only covers three specific mounting locations.
• Best for High-Performance Weight Reduction → loongrie Engine Motor Transmission, given its ultra-light 1.5-pound build compared to the heavy-duty 13.4-pound sherxibo unit.
• Best for Daily Driver Stability → sherxibo Motor Mount Kit, since the added mass and full-system approach are better suited for absorbing the rougher impacts of street driving and carrying passengers.
• Best for Track Days on Euro Cars → loongrie Engine Motor Transmission, because the kit is explicitly engineered for the torque characteristics of the CLA45 and GLA45 engines found in these platforms.
• Best for Preventative Maintenance → sherxibo Motor Mount Kit, as the inclusion of torque struts means you replace the entire suspension connection system at once, preventing future failures.
• Best for Precise Fitment → loongrie Engine Motor Transmission, due to its narrow focus on specific Mercedes OE part numbers and engine configurations, ensuring no guessing game on installation.
• Best Value for Complex Repairs → sherxibo Motor Mount Kit, because buying the full 5-piece set saves you from needing to source separate torque struts later.
• Best for Lightweight Tuning → loongrie Engine Motor Transmission, as the minimal weight addition helps maintain the agile handling characteristics expected from a Mercedes A-Class derivative.
If I were preparing my own vehicle for a weekend on the track, the choice would depend entirely on what car I was driving. For a Honda CR-V, I would unhesitatingly choose the sherxibo Motor Mount Kit. The logic is simple: track driving puts immense strain on every bolt and bushing in the drivetrain. Having a complete 5-piece kit ensures that the engine is locked down at every possible point, eliminating the risk of a loose torque strut causing catastrophic failure mid-lap. The extra weight is a small price to pay for that absolute security. Conversely, if I were driving a CLA45, I would go with the loongrie Engine Motor Transmission. Its lightweight design respects the delicate balance of the German chassis, and the specific engineering for the 2.0L turbo engine makes it the logical choice for maintaining performance without sacrificing reliability.
Yes, the data confirms the package contains a rear lower torque strut mount and a right upper torque strut mount in addition to the main motor mounts, making it a complete system.
No, the specifications list compatibility strictly for 2013-2017 B250, 2014-2019 CLA250/CLA45, and 2015-2020 GLA250/GLA45 models; it does not cover earlier generations.
Heavier mounts generally offer better vibration isolation and durability for daily driving, while lighter mounts suit performance applications where reducing mass is critical.
