Eliminator or Comp Frame Kit? Breaking Down the Differences

When it comes to building your RC crawler, choosing the right frame kit is a crucial step as its the basis and starting point for your next build. The Eliminator Frame Kit by Little Guy Racing Parts® is one of the most versatile and thoughtfully designed options available, providing everything you need to set up your rig for optimal performance and improve the rigs scale realism. Whether you’re upgrading or starting a new build, this frame kit has a lot to offer. Below, we’ll dive into the details, from the materials and design to its features and compatibility, and compare it with the equally popular Comp Frame Kit to help you decide which option suits your needs.

Chassis Design and Materials

The Eliminator Frame Kit stands out with its construction of T-7075 aluminum frame rails and shock towers, a premium material known for its exceptional strength-to-weight ratio and durability. Complementing the aluminum frame are injection-molded components, which offer a precise fit and lightweight design while significantly enhancing strength. Injection molding ensures a factory-quality finish and superior durability, making these components a standout feature of the Eliminator Frame Kit.

In contrast, the Comp Frame Kit also utilizes a T-7075 aluminum frame but incorporates more 3D-printed components. While MJF 3D-printed parts are impressively strong for their method of production, they don’t quite match the sheer strength of injection-molded components. For builders who prioritize maximum durability and long-term performance, the injection molded parts on the Eliminator Frame Kit are the more ideal choice for long term abuse.

That’s not to say the 3D-printed components in the Comp Frame Kit are inadequate—they are carefully designed and tested to handle the demands of these cars. However, when directly comparing the two, the injection molded components in the Eliminator Frame Kit provide a stronger, more refined solution, especially for those seeking a robust build that can endure the toughest obstacles and tumbles.

Wheelbase and Body Compatibility

The Eliminator Frame Kit is designed with a 161mm wheelbase, making it a perfect, factory-like fit for the Axial SCX24 Gladiator and Power Wagon bodies. This wheelbase was specifically picked for this frame kit due to working around the constraints of OEM axial bodies and factory body mounts. This 161mm wheelbase was the optimal number to get the proper look out of the trimmed oem bodies, keeping the scale look alive while stretching the wheelbase over the stock power wagon wheelbase of 152mm and the stock gladiator wheelbase of 155mm to be able to accommodate a better performing, more stable suspension, and the larger tires we all love to run.

In comparison, the Comp Frame Kit features a 163mm wheelbase, making it a great fit right out of the box for the LGRP X-Factor body. It’s also easily adaptable to bodies like the R-Factor and Brawler, offering flexibility for builders looking to mix and match different body styles using the proper body mount kits we offer.

At the end of the day, you can fit all of these bodies on both frame kits. The 2mm difference in wheelbase between the Eliminator and Comp kits is minimal and often unnoticeable unless sitting right next to each other. However, it’s worth noting that depending on your exact combination of body and frame, you may need to make minor modifications to achieve the perfect fit.

Ultimately, the Eliminator Frame Kit shines with its factory body compatibility with the Gladiator and Power Wagon, while the Comp Frame Kit offers adaptability for a wider range of our body options like the X-factor Body, R-Factor Body, and Brawler Body. Both kits ensure you can achieve the look and performance you want with a little customization where needed.

Suspension and Geometry

Suspension setup plays a big role in 1:1 and rc crawler performance, and the Eliminator Frame Kit features non-adjustable shock towers with multiple mounting points to fine-tune your shock placement. While the shock towers aren’t adjustable front to back, this doesn’t mean you’re at a disadvantage. The Eliminator Frame Kit has been carefully designed so the shock towers are already positioned in the most ideal location for optimal suspension performance, eliminating the guesswork for builders using the most popular shock options on the market.

The Comp Frame Kit, on the other hand, includes adjustable shock towers, allowing you to move your shock placement front to back as desired. This feature provides more flexibility for builders who like to experiment with suspension geometry and customize their setup to suit specific needs or preferences.

Both kits offer thoughtful designs tailored to different build styles. The Eliminator Frame Kit simplifies the process by delivering a pre-optimized shock tower position, while the Comp Frame Kit caters to those who prefer more adjustability. Ultimately, the choice comes down to whether you prefer a streamlined setup or the ability to tweak and test your suspension configuration.

Servo and Electronics Compatibility

The Eliminator Frame Kit is designed for seamless integration with stock electronics and supports both brushed motors (030 and 050 sizes) as well as common brushless setups like the the Furitek Micro Komodo / Lizard Pro esc. This flexibility makes it an excellent choice for builders who want the option to build with stock electronics now and upgrade down the road or go straight to big brushless power. Due to the design of the stock skid plate, if you plan to run the MR24 we recommend our v2 billet aluminum skid plate, this also allows you to flip the transmission in the skid plate without having to unbolt the skid plate from the car, again making this skid and frame a very versatile option.

The Comp Frame Kit is also compatible with stock electronics (Not 050 compatible), though it’s ideally suited for builds with a brushless configuration. The increased power and efficiency of a brushless configuration allow this kit to reach its full potential, particularly when paired with transmissions like the MR24 transmission or the heavy-duty transmission, both of which are compatible with the included skid plate.

While both kits accommodate stock electronics, it’s important to note that although you can run the factory SCX24™ servo, we highly recommend upgrading your servo. This is because running bigger axles and larger tires—a common choice among builders—can quickly wear out the stock servo. Both the Eliminator and Comp Frame Kits are designed to fit most micro servos on the market, giving you flexibility to choose a durable, high-performance option that can handle the increased demands of your build.

For those looking to maximize performance and durability, building either of these kits around a brushless system and upgrading the servo is the recommended approach. This ensures your RC crawler is not only functional but also equipped to tackle challenging terrain with ease.

Link Kit and Frame Features

The Eliminator Frame Kit includes a brand-new link kit featuring tubular-style T-7075 aluminum scale links. These links are not only designed for performance but also add a realistic scale appearance, making the Eliminator Frame Kit an excellent choice for builders who value aesthetics as much as functionality and a nice accent to the scale appearance of the bodies that this frame kit was designed around.

The Comp Frame Kit, in contrast, features rectangular high-clearance links. These links are designed to give you a upper hand on clearance, reducing the chances of getting hung up on obstacles. another benefit of the comp frame kit is the chassis side upper link points having 6 points of adjustment to fine tune things like pinion angle, caster, and anti-squat for your specific driving style and performance desires.

Both kits provide thoughtfully designed link systems tailored to their specific needs —whether you prioritize scale realism with the Eliminator or prefer the added clearance of the Comp Frame Kit. Your choice will depend on what matters most to your build and driving style.

Battery and Electronics Mounting

Battery and electronics placement are vital for balance and weight distribution, and the Eliminator Frame Kit doesn’t disappoint. It includes flip-able ESC and battery trays, allowing for easy customization of weight distribution and component positioning within the frame. The trays are designed to fit both factory and aftermarket batteries and electronics, giving you flexibility in your build.

The Comp Frame Kit also supports customizable battery placement on the front or rear tray but was designed to have the battery up front and esc / receiver in the rear or on the rock sliders. The Comp frame battery / esc trays are not flip-able like the Eliminator kit but employs a more specific tray design tailored to the frame system. Both systems allow for creativity, but the Eliminator’s flip-able trays may appeal to those who want quick and adaptable mounting options.

Skid Plate Design

The Eliminator Frame Kit utilizes a donor factory Axial® SCX24™ skid plate by default, providing a reliable and familiar base for your build. For those looking to upgrade, it’s compatible with the LGRP Billet Aluminum Skid Plate, which adds durability and precision to the setup. This design allows for flipping the transmission without needing to remove the skid plate, making quick adjustments easier.

The Comp Frame Kit features its own proprietary skid plate that is included with the kit. Like the Eliminator, it supports reversing the transmission if necessary, however you will have to partially disassemble the center section of the frame to flip the skid plate itself. While both options offer convenience and functionality, the skid plate designs cater to slightly different chassis and suspension configurations, giving builders flexibility depending on their preferences and needs.

Additional Features

The Eliminator Frame Kit includes a scale fo winch and fairlead, a thoughtful addition for scale enthusiasts who love adding realistic details to their crawlers. This feature is absent in the Comp Frame Kit, which focuses more on performance features rather than scale accessories out of the box.

Choosing Between the Eliminator and Comp Frame Kits

The Eliminator Frame Kit ($109.99) and the Comp Frame Kit ($109.99) cater to slightly different builder preferences, each bringing unique features to the table. If you’re looking for a setup that balances performance, scale realism and ease of assembly, the Eliminator Frame Kit stands out with its tubular links, body integrations, and scale winch details, all thoughtfully designed for a well performing and durable build.

On the other hand, the Comp Frame Kit offers a setup geared toward builders who prefer more customization and adjustability options, featuring adjustable shock towers, a slightly longer wheelbase, and high-clearance links for added ground clearance.

Ultimately, the decision comes down to your personal build goals. Whether you’re focused on creating a realistic scale crawler with the Eliminator or optimizing for competitive performance with the Comp Frame Kit, both options are designed to enhance your RC crawling experience and deliver exceptional results.
