Overview
The ARRMA Aluminium Adjustable RR Suspension Mount is a precision-engineered replacement part designed to enhance your RC car's performance and handling characteristics. Whether you own a 1/8 brushless RC buggy, truck or stunt vehicle from ARRMA's extensive lineup, this rear lower suspension mount plays a critical role in maintaining structural integrity and enabling advanced suspension tuning. This component is essential for hobbyists who want to optimise their RC car UK setup and achieve competitive handling performance on the track or off-road.
Built to the exacting standards that serious RC enthusiasts demand, this adjustable suspension mount transforms how your vehicle responds to terrain and driving inputs. It's particularly valuable for those who take their ready to run RC models beyond basic bashing and want to dial in precise geometry adjustments. The mount works seamlessly with ARRMA's adjustment block system, allowing you to fine-tune camber, caster and other critical suspension parameters to suit your driving style and track conditions.
This is a genuine ARRMA spare part, manufactured using CNC precision and aerospace-grade aluminium construction. It's ideal for anyone operating a brushless RC buggy, speed truck or stunt truck who recognises that suspension geometry directly impacts cornering speed, stability and overall vehicle control. If you're serious about RC performance, understanding and optimising components like this suspension mount is essential to extracting every ounce of capability from your RC investment.
Key Features
- Precision CNC Machined from High-Quality Aluminium — This component is manufactured using computer numerical control machining from premium-grade aluminium, ensuring exact tolerances and structural consistency that you simply cannot achieve with plastic parts or inferior casting methods. CNC machining guarantees that each mount is identical to the last, providing reliable performance and easy replacement or upgrades across multiple vehicles.
- Anodised Finish with Laser-Etched TLR Tuned Branding — The aluminium construction is protected by a tough anodised coating that resists corrosion, oxidation and weathering, whilst the laser-etched TLR Tuned logo adds a professional, race-quality aesthetic to your RC car. The anodising process hardens the aluminium surface, making it more durable against impacts and abrasions during normal use and maintenance.
- Significantly Enhances Strength and Durability — By upgrading to this aluminium suspension mount from standard plastic components, you gain substantially improved rigidity and longevity. The aluminium construction resists flexing and deformation that occurs during hard driving, which means your suspension geometry remains stable and consistent throughout extended driving sessions.
- Rear Gearbox Integration with Adjustment Capability — This mount fits directly to the rear of the rear gearbox on compatible ARRMA vehicles, positioning it as a critical interface between your drivetrain and suspension system. The design incorporates compatibility with adjustment blocks, allowing you to modify suspension geometry without purchasing entirely new components.
- Works with Adjustment Blocks for Geometry Tuning — The mount accepts ARRMA's Lower Arm Adjustment Block Set, enabling you to adjust the suspension arm angles with precision. This feature is invaluable for RC enthusiasts who want to experiment with different suspension setups, optimise handling for specific track conditions, or match their vehicle's geometry to their personal driving preferences.
Technical Performance
This rear lower suspension mount represents the engineering philosophy that underpins TLR Tuned components—precision, adjustability and durability working in harmony. The use of high-quality aluminium instead of plastic or softer metals means the mount will not flex or absorb energy that should be transmitted through your suspension geometry. This direct energy transfer keeps your suspension arms at their intended angles, maintaining consistent handling characteristics lap after lap. The CNC machining process ensures tolerances measured in fractions of a millimetre, which is essential when you're adjusting suspension geometry to fine-tune your vehicle's cornering performance. The anodised surface treatment adds approximately 0.0002 inches of protective coating, which might sound minimal but translates to genuine resistance against moisture ingress, salt-water corrosion and mechanical wear. For RC enthusiasts operating 1/8 scale brushless buggies and trucks that demand precision handling, this level of engineering detail directly influences whether you can dial in perfect suspension balance or whether you're constantly fighting geometry inconsistencies. The adjustability feature works hand-in-hand with the structural rigidity—the mount holds its shape precisely, allowing your adjustments to take effect exactly as intended.

Frequently Asked Questions
- Which ARRMA RC vehicles is this suspension mount compatible with? — This mount is compatible with multiple ARRMA 1/8 scale models including the KRATON 6S, NOTORIOUS 6S, OUTCAST 6S, TALION 6S, TYPHON 6S and TYPHON 6S TLR Tuned variants. It works with both RTR (Ready to Run) models and roller kits, though you should check your specific vehicle's manual to confirm fitment before ordering.
- What suspension improvements will I experience by upgrading to aluminium? — Upgrading from plastic to aluminium rear suspension mounts eliminates flex and deformation that occurs during aggressive driving. This means your suspension geometry remains consistent, cornering becomes more predictable, and you'll notice improved stability during acceleration and braking. The ride quality also becomes more responsive because energy is no longer being absorbed by flexing plastic components.
- Do I need any special tools to install this suspension mount? — You will need standard RC model tools including hex drivers, screwdrivers and potentially a suspension height gauge if you're making detailed adjustments. The mount bolts directly to your rear gearbox using existing fastening points on compatible ARRMA vehicles, so installation is straightforward for anyone with basic RC maintenance experience.
- Can I adjust my vehicle's handling with this component alone? — This mount forms part of a complete suspension tuning system. To achieve meaningful geometry adjustments, you'll need to pair it with the Lower Arm Adjustment Block Set (ARA320658), which provides the actual adjustment mechanism. The mount itself maintains your geometry precisely once dialled in, but the adjustment blocks are what allow you to change it.
- Is this suitable for beginners or only experienced RC drivers? — This is suitable for intermediate to advanced RC enthusiasts who understand suspension principles and want to optimise their vehicle's handling. Complete beginners should first learn how their ready to run RC cars behave out of the box before investing in geometry adjustments. However, once you're comfortable with basic maintenance, upgrading to quality components like this mount is a logical next step in your RC hobby progression.
- Why is the anodised finish important? — The anodised coating protects the aluminium from corrosion, especially important if you drive your RC car UK in damp conditions or near coastal areas with salt spray. Without this protective layer, raw aluminium oxidises and becomes discoloured, and protective oxide layers can eventually compromise the component's structural integrity. The anodised finish ensures your suspension mount will remain pristine and perform consistently for years.
