Overview
The VITAVON CNC Alu7075 Shock End Lower for Kraton 8S OUTCAST 8S is a premium-quality upgrade component designed specifically for serious RC enthusiasts running ARRMA's flagship 1/5 scale monsters. This precision-engineered aluminium shock end lower is crafted from high-grade 7075 aluminium alloy, a material renowned in both aerospace and high-performance RC applications for its exceptional strength-to-weight ratio and durability. Whether you're a competitive racer, weekend basher, or dedicated crawler pilot, this component delivers the reliability and performance upgrades that separate good RC setups from great ones.
This particular version is engineered specifically for the EXB (Enhanced Experience Base) variant with 6mm shock shafts, making it essential if you're running the later generation ARRMA Kraton 8S or Outcast 8S models with upgraded shock systems. The investment in quality aftermarket suspension components like this shock end lower can dramatically improve handling, durability, and overall driving experience on everything from technical rock crawling terrain to high-speed bash runs across the UK countryside. For anyone serious about getting the best performance from their 1/5 scale RC buggy or short course truck, VITAVON's precision CNC-machined parts represent excellent value and proven quality in the RC car UK market.
Available in three stunning colours—Silver, Black, and Red—this shock end lower allows you to customise your ARRMA machine to match your personal style whilst maintaining the engineering excellence that VITAVON is recognised for. Installation is straightforward for anyone with basic RC maintenance knowledge, though we always recommend consulting your vehicle manual or seeking guidance from experienced RC enthusiasts if you're new to suspension upgrades.
Key Features
- High-Grade 7075 Aluminium Construction — Manufactured from premium 7075 aluminium alloy, this shock end lower offers exceptional rigidity and durability compared to standard plastic components, which means it resists bending, cracking and fatigue even under extreme driving conditions and repeated impacts typical of competitive RC use.
- CNC-Machined Precision — Every component is produced using advanced computer-controlled machinery to exact tolerances, ensuring perfect fitment to your ARRMA shock assembly and consistent performance across every unit, eliminating the quality variance sometimes found in mass-produced plastic parts.
- EXB Version 6mm Shock Shaft Compatibility — Specifically engineered for the EXB variant featuring 6mm shock shafts (not the RTR 5mm version), this ensures perfect mechanical compatibility with your upgraded ARRMA Kraton 8S or Outcast 8S suspension system without modification or improvisation.
- Perfect Fit for ARRMA Kraton 8S and Outcast 8S — Engineered specifically to work seamlessly with both the ARA110002BT1/ARA110002BT2 Kraton 8S and ARA5810B/ARA5210B Outcast 8S platforms, guaranteeing hassle-free installation and optimal performance without compatibility issues.
- Durable Design for All Terrain Types — Whether you're running your 1/5 scale RC buggy on rocky crawler terrain, smooth race tracks, high-speed bash courses or muddy off-road UK trails, this shock end lower is engineered to withstand the demands of every driving style and environment.
- Multiple Colour Options — Choose from Silver, Black, or Red finishes to match your vehicle's aesthetic, allowing you to create a cohesive, personalised build that looks as professional as it performs.
- Direct Replacement Component — This part slots directly into your existing shock assembly, making upgrades simple and accessible even for intermediate RC enthusiasts without requiring advanced technical knowledge or additional modifications.
Technical Performance
The VITAVON CNC Alu7075 Shock End Lower represents a significant performance upgrade over standard plastic shock components found on many ready to run RC vehicles. The use of 7075 aluminium alloy—a material specification commonly found in professional-grade racing equipment and aerospace applications—delivers superior strength characteristics whilst maintaining a lightweight profile that won't negatively impact your vehicle's weight distribution or suspension geometry. CNC machining ensures that every component meets identical specifications, eliminating manufacturing tolerances that could lead to binding, misalignment or uneven suspension response. For 1/5 scale RC buggies and short course trucks like the ARRMA Kraton 8S and Outcast 8S, suspension reliability is critical; even small inconsistencies in shock end geometry can translate to handling problems, tyre wear issues, and reduced driver control during high-speed manoeuvres or technical terrain navigation. This upgrade addresses those concerns head-on, providing the mechanical precision that competitive and serious hobbyist drivers demand. The engineering is specifically calibrated for the 6mm shock shaft diameter of EXB-variant systems, ensuring perfect clearances and engagement without play or looseness. Whether you're investing in brushless RC upgrades across your entire vehicle or focusing on targeted suspension improvements, this shock end lower works in harmony with modern high-performance electronics to deliver measurable improvements in handling responsiveness, cornering consistency, and overall durability—ultimately extending the service life of your complete suspension assembly and reducing maintenance-related downtime.

Frequently Asked Questions
- Is this shock end lower compatible with my ARRMA Kraton 8S or Outcast 8S? — Yes, this component is specifically engineered for both the ARA110002BT1/ARA110002BT2 Kraton 8S and ARA5810B/ARA5210B Outcast 8S platforms, provided you are running the EXB variant with 6mm shock shafts. It is not compatible with the earlier RTR version featuring 5mm shock shafts, so please verify your shock shaft diameter before ordering.
- What is the difference between the EXB 6mm and RTR 5mm versions? — The EXB version features a larger 6mm shock shaft diameter and is designed for upgraded suspension systems on newer ARRMA models, whilst the RTR 5mm version suits standard stock shocks on earlier factory-built vehicles. These are not interchangeable, so confirming your shock specifications before purchase is essential.
- Why upgrade from plastic to aluminium shock components? — Plastic shock ends are prone to cracking, warping, and wearing over time, especially under the stresses of competitive driving or rough terrain. Aluminium 7075 alloy resists these failure modes, maintains dimensional accuracy over thousands of cycles, and provides superior rigidity that translates to more consistent handling and better tyre contact throughout your suspension's range of motion.
- Is this a direct plug-and-play replacement? — Yes, this shock end lower is engineered as a direct replacement for your OEM component and requires no modifications or additional parts. If you have basic RC maintenance experience, installation should take just a few minutes using standard tools.
- Which colour should I choose? — All three available colours—Silver, Black, and Red—are functionally identical. Choose the finish that best complements your vehicle's colour scheme or personal preference; many enthusiasts match their shock components to their body shell or trim colours for a fully integrated aesthetic.
- Is this suitable for beginners to RC? — Whilst this is an upgrade component rather than a complete vehicle or ready to run RC system, it is well-suited to intermediate hobbyists who are already familiar with basic maintenance on their ARRMA Kraton 8S or Outcast 8S. Beginners should consider purchasing their first complete ready to run RC vehicle before investing in individual upgrade components.
- How does this improve my RC driving experience? — Higher-quality suspension geometry and materials mean more predictable handling, better traction consistency, reduced suspension binding, and longer component lifespan. Over time, you'll notice improved cornering precision, more responsive steering input feedback, and reduced maintenance costs due to the durability of premium aluminium versus plastic alternatives.
