Overview
The ARRMA Alum Adjustable Front Upper Suspension Mount -TLR (model Z-ARA320654) is a precision-engineered suspension component designed to enhance the performance and tunability of your ARRMA RC buggy. This aluminium front upper suspension mount is specifically engineered for ARRMA's 1/8 scale TYPHON 6S brushless RC buggies, offering serious performance gains for anyone looking to optimise their RC car's handling characteristics. Whether you're a competitive racer fine-tuning your setup or a weekend RC enthusiast seeking improved suspension geometry, this adjustable mount delivers the durability and precision that modern RC cars demand.
Built from high-quality aluminium and precision CNC-machined for exacting tolerances, this suspension component represents ARRMA's commitment to professional-grade RC engineering. The mount features TLR tuning, which means it has been developed through collaboration with TLR Racing to deliver optimised geometry and handling characteristics. The anodised finish with laser etching not only protects the aluminium from corrosion but also provides a stylish appearance that complements your RC buggy's looks. This is more than just a functional part—it's a performance upgrade that serious UK RC hobbyists rely upon.
The adjustable design allows you to modify the upper arm geometry of your front suspension, giving you multiple tuning options to dial in the perfect handling for different track conditions, driving styles, and race formats. This level of adjustability is what separates competitive RC setups from basic build-and-bash cars, making it an essential component for anyone serious about maximising their RC buggy's potential.
Key Features
- Precision CNC Machined Aluminium Construction — The mount is precision CNC-machined from high-quality aluminium, ensuring exact dimensional accuracy and consistent fitment across multiple units. This machining process eliminates tolerances that could affect handling, creating a reliable, repeatable suspension geometry that serious RC racers depend on.
- Anodised Finish with Laser Etching — The anodised surface treatment provides robust protection against corrosion and oxidation, whilst the laser etching adds a professional, branded appearance. This finishing process extends the lifespan of the component and maintains its aesthetic appeal through seasons of competitive racing.
- TLR Tuned Design — Engineered through TLR Racing's suspension expertise, this mount delivers optimised upper arm geometry that has been developed and tested by racing professionals. TLR tuning means your RC buggy benefits from competition-proven suspension design without requiring expensive custom fabrication.
- Adjustable Suspension Geometry — Works in conjunction with ARRMA adjustment blocks to allow fine-tuning of the upper arm mounting position. This adjustability lets you modify camber angles, caster angles, and roll centre height to match your driving style, track conditions, and weather—critical adjustments for serious RC car UK competitors.
- Enhanced Strength and Durability — The robust aluminium construction significantly increases the strength of your front suspension compared to stock plastic components. This durability improvement is essential when running your RC buggy at high speeds on rough terrain or in competitive racing scenarios where suspension stress is extreme.
- Compatible with Adjustment Blocks — This mount is specifically designed to work seamlessly with ARRMA's Front Upper Arm Adjustment Block Set, which provides multiple caster inserts and eccentric upper arm inserts for comprehensive suspension tuning. This compatibility ensures that your investment in tunability is fully realised.
Technical Performance
This suspension mount represents the intersection of engineering precision and competitive RC performance. Manufactured from high-quality aluminium using CNC machining technology, the component achieves tolerances that ensure repeatable suspension geometry across multiple vehicles and rebuilds. The material choice—aluminium rather than plastic—provides superior strength-to-weight ratio whilst maintaining the lightweight characteristics essential for RC buggies. The anodised surface treatment adds approximately 0.003-0.005 inches of corrosion-resistant coating, protecting the underlying aluminium from oxidation during wet weather RC racing sessions common in the UK climate. When combined with the required adjustment blocks (ARA320657), shock tower (ARA320644), and hinge pins (ARA330732), this mount becomes part of an integrated suspension system engineered to deliver adjustable geometry across four different caster positions and twelve different camber settings. The TLR Racing tuning ensures that the suspension kinematics—the geometric relationship between suspension components during compression and extension—are optimised for balanced handling characteristics across various driving conditions. This level of engineering detail is what separates competitive-grade RC setups from casual hobby builds.

Frequently Asked Questions
- Which ARRMA RC buggies is this suspension mount compatible with? — This suspension mount is designed for ARRMA's 1/8 scale TYPHON 6S brushless buggy range, including the standard TYPHON 6S 4X4 RTR (ARA106046), the TYPHON 6S 4X4 RTR in black (ARA8606V5), the TYPHON 6S TLR Tuned roller in pink and purple (ARA8306), and the TYPHON 6S TLR Tuned RTR in red and blue (ARA8406). If you're unsure whether this mount suits your specific RC buggy model, we recommend checking your vehicle's manual or contacting us directly.
- How does this adjustable mount improve my RC buggy's handling? — The adjustable design allows you to modify the upper arm geometry by changing the mounting position using the supplied adjustment blocks. This changes critical suspension angles including caster angle (which affects straight-line stability and steering response) and camber angle (which affects tyre contact patch during cornering). By adjusting these angles, you can fine-tune your RC car's handling to suit different track surfaces, weather conditions, and your personal driving style—making this mount essential for competitive racing.
- What does TLR tuning mean on this suspension mount? — TLR Racing is a renowned suspension engineering specialist in the RC racing community. TLR-tuned components have been developed and refined through competitive racing experience, ensuring that the suspension geometry is optimised for balanced, predictable handling characteristics. This means your ARRMA buggy benefits from professional-level suspension design without needing expensive custom fabrication.
- Is this a difficult component to install on my ARRMA RC buggy? — Installation requires basic mechanical skills and tools. The mount needs to be fitted to your shock tower (ARA320644) using the hinge pins (ARA330732) and works in conjunction with the adjustment blocks (ARA320657). If you're comfortable performing basic RC car maintenance, installation should be straightforward. However, if you're new to suspension work, we recommend consulting your ARRMA buggy's manual or seeking guidance from experienced RC hobbyists in the UK community.
- Will this suspension mount make my RC buggy faster? — This mount doesn't directly increase speed, but improved suspension geometry can enhance traction, reduce weight transfer during cornering, and improve steering response—all factors that collectively can improve lap times on race tracks. By allowing you to optimise suspension angles for specific conditions, this adjustable mount gives you the tuning flexibility that competitive RC buggy racers use to gain performance advantages.
- What is the difference between this and a plastic upper suspension mount? — Aluminium construction provides significantly greater strength and durability compared to plastic, particularly under the high stresses of competitive racing. Aluminium also provides better precision in CNC machining, ensuring tighter tolerances and more consistent suspension geometry across rebuilds. The TLR tuning also means this mount has been engineered by racing professionals specifically for performance, whereas basic plastic mounts are typically designed for durability rather than competitive tuning.
- Can I use this mount on other RC car brands? — No, this mount is specifically designed for ARRMA vehicles and is not compatible with other RC car manufacturers. ARRMA suspension geometry, shock tower dimensions, and hinge pin sizes are proprietary to ARRMA's engineering specifications. Always verify fitment information before purchasing suspension components for your RC car.
