Overview
The RPM Caster Blocks for Traxxas Electric Stampede, Rustler, Slash and Bandit represent the final link in a complete, bulletproof front suspension upgrade for your RC truck. Whether you're a weekend basher pushing your 2WD RC car to its limits or a serious enthusiast looking to reinforce the most heavily impacted areas of your vehicle, these purpose-engineered caster blocks deliver exceptional durability and strength where it matters most. RPM has redesigned these critical suspension components to slim down unnecessary bulk whilst simultaneously improving strength and durability, making them an essential upgrade for anyone running a Traxxas electric 2WD truck in the UK RC hobby scene.
These replacement caster blocks are specifically engineered for the Traxxas Slash 2WD, electric Rustler, and electric Stampede 2WD models, offering a direct bolt-on upgrade that requires no additional parts or modifications to install. If you're serious about extending the lifespan of your RC truck and maintaining consistent front-end geometry through aggressive bashing and kerb clipping, the RPM Caster Blocks are a must-have upgrade. The positive feedback from UK RC enthusiasts confirms that these blocks hold up exceptionally well even after multiple hard landings and impact events that would typically damage stock components.
Backed by RPM's industry-leading breakage warranty, these caster blocks give you peace of mind knowing you've invested in genuine, purpose-designed components rather than relying on fragile OEM parts. Each package contains a complete pair—one left side and one right side caster block—ready to install on your vehicle.
Key Features
- Ultra-durable nylon compound — RPM's trademark blend of ultra-durable and super-strong nylons provides exceptional impact resistance and longevity compared to stock plastic components, meaning your caster blocks will survive the rough treatment that comes with serious RC bashing and kerb clipping without breaking or flexing under load.
- Redesigned for reduced bulk — These blocks have been engineered to eliminate unnecessary material whilst maintaining full strength and structural integrity, resulting in a lighter, cleaner appearance without compromising the geometry or performance characteristics of your truck's front suspension.
- Stock replacement compatibility — Direct replacement for Traxxas stock part number 3632, these caster blocks integrate seamlessly into your existing suspension setup with zero modifications or additional parts required, making installation straightforward for hobbyists of all experience levels.
- Retains factory caster geometry — The RPM Caster Blocks maintain the factory 30-degree caster settings for both Rustler and Stampede models, ensuring that your truck's handling characteristics remain true to the original design whilst benefiting from dramatically improved durability and impact resistance.
- Industry-leading warranty coverage — Backed by RPM's best-in-class breakage warranty for the RC hobby industry, you can rest assured that your investment is protected against manufacturing defects and premature failure.
- Paired left and right components — Each package includes both left-side and right-side caster blocks, giving you a complete front-end upgrade in one purchase with no additional parts needed.
- Proven durability in the field — Real-world testing from UK RC enthusiasts confirms that these caster blocks maintain structural integrity through extensive bashing, hard landings, and aggressive driving conditions that would typically result in broken OEM components.
Technical Performance
The RPM Caster Blocks represent a significant engineering advancement over the fragile stock Traxxas components they replace. Manufactured from RPM's proprietary blend of ultra-durable and super-strong nylons, these caster blocks are specifically formulated to withstand the extreme loads and impacts that occur during aggressive RC truck driving. The caster blocks are the critical connection point between your truck's suspension arms and wheel hubs, making them essential structural components that must maintain precise geometry under load. Stock plastic caster blocks commonly fail when subjected to hard kerb strikes, aggressive landings, or sustained high-speed bashing, resulting in bent geometry and unpredictable handling. RPM's reinforced design eliminates this weakness entirely. The blocks have been strategically redesigned to eliminate unnecessary bulk without sacrificing any structural strength, resulting in a component that is simultaneously lighter and more durable than the original Traxxas part number 3632. The maintained 30-degree caster setting for Rustler and Stampede models ensures that your truck's suspension geometry remains optimised for the handling characteristics these vehicles were designed for. Installation is straightforward—as a direct stock replacement requiring no modifications or additional components, you can upgrade your truck's front suspension durability in minutes without specialist knowledge or tools. The performance benefit is immediately noticeable; your truck will maintain consistent handling through successive hard impacts, and you'll experience fewer breakages that result in downtime and repair frustration.

Frequently Asked Questions
- Will these RPM Caster Blocks work on my Traxxas truck? — These RPM Caster Blocks (part number 80715) are specifically designed as a direct replacement for Traxxas stock part number 3632 and are compatible with the Traxxas Slash 2WD, electric Rustler, electric Stampede 2WD, and electric Bandit models. However, they will not work on the nitro versions of the Rustler or Stampede, nor will they fit the 4WD versions of either the Stampede or Slash. Always verify your truck's drive system and engine type before ordering to ensure compatibility.
- Do I need any additional parts or modifications to install these caster blocks? — No. These RPM Caster Blocks are designed as direct stock replacements and require no additional parts, modifications, or specialist knowledge to install. They bolt directly onto your existing suspension using your truck's current hardware, making this an ideal upgrade for RC hobbyists of all skill levels.
- How much more durable are these compared to the stock Traxxas caster blocks? — The RPM Caster Blocks are manufactured from RPM's proprietary ultra-durable and super-strong nylon blend, which significantly outperforms the fragile plastic used in stock Traxxas components. Real-world testing confirms that these blocks survive extended bashing, hard kerb strikes, and aggressive landings without breaking or cracking, whereas stock components commonly fail under these conditions. They're backed by RPM's industry-leading breakage warranty, demonstrating the manufacturer's confidence in their durability.
- Will upgrading to RPM Caster Blocks change my truck's handling? — No. These caster blocks maintain the factory 30-degree caster settings for Rustler and Stampede models, ensuring that your truck's suspension geometry and handling characteristics remain identical to the original design. The upgrade purely improves durability and reliability without altering performance characteristics.
- Are these suitable for beginners? — Yes. As a direct bolt-on replacement requiring no modifications, these caster blocks are ideal for beginners looking to improve their truck's durability. Installation requires only basic tools and takes just minutes. The simplified design and straightforward installation make this an excellent first upgrade for anyone new to RC truck maintenance and customisation.
- Why should I upgrade from stock caster blocks? — Stock Traxxas caster blocks are notoriously fragile and commonly break during normal bashing, kerb clipping, and hard landings. This breakage results in bent geometry, unpredictable handling, and costly downtime. RPM's reinforced caster blocks eliminate this recurring problem by delivering exceptional impact resistance and durability, allowing you to bash harder and more frequently without worrying about component failure.
