RPM Adjustable Rear Body Posts and Mounts Traxxas Slash 2WD Stampede RPM81142

Overview

The RPM Adjustable Rear Body Posts & Mounts for Traxxas Slash 2WD, Stampede and Nitro Stampede represent a significant upgrade over the factory standard components. If you're running a Traxxas short course truck in the UK and want to fine-tune your vehicle's handling characteristics, this is an essential chassis modification that belongs in every serious basher's toolkit. These adjustable body mounts allow you to dial in the perfect body height for your specific driving conditions, whether you're tackling high-speed circuits, technical rock gardens, or anything in between.

RPM has designed this system with durability and strength at its core, whilst maintaining the flexibility needed to absorb impacts that could otherwise damage more fragile internal components of your RC car. This is not a cheap plastic alternative—this is a properly engineered upgrade that will outlast the stock components by a significant margin. Whether you're a weekend basher pushing your Slash to its limits or a track competitor seeking that extra competitive edge, these body mounts deliver the adjustability and durability required for serious RC short course truck racing and bashing in the UK.

The beauty of this system lies in its simplicity. Rather than being locked into a single body height determined by the manufacturer, you now have complete control over how your truck sits on the chassis. This adjustability opens up a world of tuning possibilities that can dramatically improve your vehicle's performance and appearance.

Key Features

• Fully Adjustable Body Height — The body can be lowered as much as 3/16 inches or raised as much as 3/8 inches simply by moving the posts up or down on the mounts, allowing you to dial in the perfect ride height for your driving style and track conditions without purchasing additional parts.
• Stock Height Option — The unique body post mounting system allows the option of using the original stock body height on the chassis, meaning you can start with factory geometry and adjust from there as you develop your tuning knowledge.
• I-Beam Construction — Each mount features an I-beam shape throughout, which provides exceptional structural strength and rigidity whilst maintaining a lightweight design, ensuring these parts can handle the toughest landings and impacts without flexing or breaking.
• Thicker Than Stock Materials — Everything about these body mounts and posts is beefier than the stock alternative, from the thicker than stock screw mounts to the premium plastic formulation, meaning they will withstand far more punishment over their lifetime.
• Twin Screw Securing System — The body posts are held on to the mounts using twin screws rather than single fasteners, dramatically increasing the clamping force and preventing the body from shifting during aggressive driving or high-speed impacts.
• Impact Absorption Design — The flexible mounting system is strong enough to handle extreme conditions whilst still allowing enough flex to absorb impacts that could otherwise damage other more fragile internal components of the chassis, protecting your investment.
• Simple Installation — The clever design means installation is straightforward, requiring only basic tools and a few minutes of your time to mount these upgrades on your existing Traxxas Slash or Stampede chassis.

Technical Performance

The RPM Adjustable Rear Body Posts & Mounts represent a significant engineering upgrade over factory components. The I-beam construction throughout each mount provides exceptional structural rigidity, critical for maintaining consistent body geometry during high-speed corners and aggressive driving. The thicker-than-stock screw mounts distribute loads more effectively across a larger surface area, preventing stress concentration that leads to cracking or failure. Twin screws holding the body posts to the mounts create a significantly stronger joint than the single-screw stock design, with doubled clamping force that prevents any movement or flex at this critical interface. The flexible mounting system achieves a remarkable balance: the posts are rigid enough to maintain precise body geometry and alignment, yet possess enough compliance to absorb impacts that would otherwise transmit shock loads directly into sensitive internal chassis components. This engineering philosophy protects your suspension, drivetrain, and electronics whilst maintaining the aerodynamic and handling benefits of your body choice. The premium plastic formulation used throughout these components is noticeably thicker and more durable than stock alternatives, delivering superior resistance to UV degradation, moisture, and the thermal stress cycles that come with intensive bashing and racing in UK climate conditions. The adjustability range—lowering 3/16 inches or raising 3/8 inches—provides meaningful tuning potential without requiring multiple sets of parts, allowing you to optimise centre of gravity for different track layouts and driving styles.

Frequently Asked Questions

• Will these body mounts fit my Traxxas Slash 2WD or Stampede? — Yes, these mounts are specifically designed for the Traxxas Slash 1/10 2WD (all VXL-3S variants and Extreme HD versions) and the Stampede and Nitro Stampede models. They are a direct replacement for the factory body posts and require no additional modifications to your chassis.
• How much adjustment range do these body mounts provide? — The posts can be lowered as much as 3/16 inches from the stock position or raised as much as 3/8 inches, giving you substantial tuning flexibility to dial in the perfect body height for your specific driving conditions, track layout, and personal preference.
• Why would I want to adjust the body height on my RC truck? — Body height adjustment affects multiple aspects of your vehicle's performance: lowering the body improves centre of gravity and handling responsiveness, whilst raising it can provide additional ground clearance for rough terrain bashing and reduces the risk of body damage from high-speed impacts into obstacles.
• Are these mounts stronger than the stock components? — Significantly stronger. Everything about these mounts is beefier than stock, featuring thicker screw mounts, twin screws holding the posts (versus single screws on stock), and an I-beam structural design throughout. Customer reviews confirm they are substantially more durable than the factory components.
• Is this suitable for beginners? — Yes, absolutely. Installation requires only basic tools and takes just a few minutes. The adjustability means you can start with the stock height setting and gradually experiment with different positions as you gain experience, making this an excellent first modification for any Slash or Stampede owner.
• What materials are used in these mounts? — RPM uses premium plastic formulation throughout, significantly thicker than the stock alternative. The I-beam design is moulded into each mount for optimal strength-to-weight ratio. All fasteners are included in the package.
• Will these mounts improve my truck's performance? — Yes, by allowing you to optimise body height for your driving style and conditions, you can achieve better handling, improved weight distribution, enhanced ground clearance, and a more planted feel through corners, making them an essential upgrade for serious bashers and racers.
• How do I know which height setting to use? — For general bashing, the stock height is a good starting point. For track racing, lower settings improve handling but reduce ground clearance. For rough terrain or jump-heavy driving, raised settings provide more protection. Experiment to find the sweet spot for your style.
