Vitavon Alu7075 Rear Upper link/Toe Link Adjustable for Arrma BIG ROCK 6S BLX - Vitavon VITAR340071

Overview

The Vitavon Alu7075 Rear Upper Link/Toe Link Adjustable for Arrma BIG ROCK 6S BLX represents a premium upgrade option for serious RC enthusiasts looking to fine-tune the suspension geometry of their Arrma BIG ROCK 6S BLX monster truck. Whether you're a dedicated basher exploring suspension adjustments or a competitor seeking to optimise your vehicle's handling characteristics, this precision-engineered component offers the flexibility and durability required for demanding off-road RC car use in the UK and beyond. Manufactured from high-quality aerospace-grade aluminium 7075, these adjustable links allow you to dial in the perfect toe angle for your specific driving style and terrain conditions.

This is not simply a replacement part—it's a suspension tuning tool that empowers you to extract maximum performance from your Arrma BIG ROCK 6S BLX. The adjustability range from 119mm to 153mm means you can experiment with different suspension geometries to suit everything from high-speed outdoor tracks to technical crawling courses. For anyone serious about RC performance in the UK market, suspension geometry control is essential, and these links deliver the quality and precision you need.

Vitavon has built a reputation for producing CNC-machined aluminium components that match or exceed OEM specifications whilst offering superior adjustability. These upper links and toe links are designed to work seamlessly with the Arrma BIG ROCK 6S BLX platform, ensuring perfect fitment and compatibility with your existing setup.

Key Features

• Premium Alu7075 Aluminium Construction — Made from aerospace-grade aluminium 7075, this material is significantly stronger and more rigid than standard aluminium alloys, meaning these links resist bending and deformation even during aggressive driving, maintaining consistent suspension geometry lap after lap and session after session.
• Adjustable Length Range (119mm to 153mm) — The generous adjustment range allows you to modify the toe angle of your Arrma BIG ROCK 6S BLX to suit different driving conditions, track layouts, and driving styles, from maximum stability on high-speed runs to increased responsiveness for technical manoeuvres.
• CNC-Machined Precision — These components are CNC-machined to exact tolerances, ensuring consistent fitment and eliminating the play or looseness sometimes found in cast or stamped alternatives, which translates to more predictable and responsive handling.
• 3.2mm Rod End Holes with 7.9mm Width — The precisely dimensioned rod end holes ensure perfect compatibility with standard Arrma ball studs and rod ends, whilst the 7.9mm width provides excellent structural support without excess weight.
• Sold as a Pair — Each purchase includes both the left and right unit, making it straightforward to install and ensuring symmetrical suspension geometry across the vehicle.
• Fits Front and Rear Positions — These versatile links work at both the front and rear of your Arrma BIG ROCK 6S BLX, offering flexibility in your suspension upgrade strategy; however, you'll need to purchase two pairs to upgrade all four positions on your truck.
• Silver Anodised Finish — The anodised aluminium finish provides excellent corrosion resistance, making these links suitable for use in wet conditions common in UK RC racing and bashing, whilst maintaining a professional appearance.

Technical Performance

These adjustable upper links represent a significant step up from stock plastic or cast-metal alternatives. The use of alu7075—a premium aluminium alloy typically reserved for aerospace and high-performance engineering applications—ensures that these components can withstand the demanding forces generated by a powerful 6S LiPo-powered Arrma BIG ROCK 6S BLX without flex or failure. The CNC-machined construction means every hole, every angle, and every surface is produced to precise specifications, eliminating tolerances that could introduce slop into your suspension system. In practical terms, this means better handling feedback, more consistent lap times, and a vehicle that responds predictably to your steering inputs. The adjustable length feature is particularly valuable for UK RC enthusiasts who may race or bash on different tracks and terrain throughout the week—quick adjustments to suspension geometry can transform your vehicle's performance without requiring complete component swaps. The rod end holes at 3.2mm and 7.9mm width are engineered to work with standard Arrma ball studs, ensuring straightforward installation without the need for aftermarket adapters or modifications. Whether you're running at high speed on a smooth racing circuit or navigating technical rocky terrain, these links provide the rigidity and precision required for optimal performance.

Frequently Asked Questions

• Do I need to buy multiple pairs for my Arrma BIG ROCK 6S BLX? — Yes. Each purchase includes one pair (left and right), which covers either the front or rear suspension positions. Since these links fit both front and rear, you'll need to purchase two pairs if you want to upgrade all four positions on your truck—one pair for the front and one pair for the rear.
• What is the difference between these adjustable links and the stock Arrma parts? — Stock Arrma links are typically made from plastic or lower-grade aluminium and offer no length adjustment. The Vitavon Alu7075 links are CNC-machined from premium aerospace-grade aluminium, offering a 119mm to 153mm adjustment range, superior rigidity, and the ability to fine-tune your suspension geometry. This means better handling, more consistent performance, and longer lifespan.
• Can I use these links at both the front and rear of my truck? — Yes, these are designed to work at both front and rear positions, offering flexibility in how you upgrade your suspension. However, since each pair only covers one axle position, you'll need two pairs for a complete front and rear upgrade.
• How do I adjust the length of these links? — The adjustable length is achieved by modifying the position of the rod ends or ball studs along the 119mm to 153mm range. This typically requires loosening the ball stud retainers and repositioning them along the link body, then retightening to secure the new length. Consult your Arrma BIG ROCK 6S BLX manual for specific adjustment procedures.
• Are these waterproof for wet conditions? — The anodised aluminium finish provides excellent corrosion resistance, making these links suitable for use in wet conditions and damp UK weather. However, the rod ends themselves should be maintained and inspected regularly, as is standard practice with any RC suspension components used in wet environments.
• What is the advantage of alu7075 over standard aluminium? — Alu7075 is significantly stronger and more rigid than standard aluminium alloys, offering superior resistance to bending, cracking, and deformation. This means these links will maintain their shape and geometry through sustained high-performance driving, ensuring consistent handling and longer component lifespan compared to weaker materials.
• Is this suitable for beginners? — Whilst these links are straightforward to install, adjusting suspension geometry requires understanding how toe angle affects vehicle handling. Beginners may find these most useful as a long-term upgrade after becoming familiar with their vehicle's handling characteristics. However, the installation process itself is within the capability of anyone comfortable performing basic RC maintenance.
• Will these links improve my lap times? — Adjustable suspension geometry allows you to optimise your vehicle's handling for specific tracks and driving styles. Experienced drivers can use the adjustment range to dial in the perfect setup for maximum performance, potentially improving lap times. Beginners should focus first on developing consistent driving technique before making advanced suspension adjustments.
