RCAWD Kraton 8S & Roller Shock Absorber Set
These RC shocks are designed as a front and rear upgrade for 1/5 ARRMA 8S and Roller platforms. They accommodate Kraton 8S 4×4 BLX configurations and bash rollers, replacing parts ARA330609 and ARA330610. The shocks come pre-filled with a small amount of oil and feature adjustable threaded collars and springs for fine-tuning ride height and damping. Aluminum alloy construction uses 7075 and 6061-T6 components with hard-anodized finishes for durability and reduced heat buildup. The result is a scalable solution that improves ride quality and overall stability on rough terrain and during high-speed runs.
Key features include pre-filled oil, threaded shock collars for height and tension adjustments, and top-tier aluminum construction. This kit supports precise tuning for different track conditions and driving styles, helping you optimize both stability and wheel contact with the ground.
FLMLF Plastic Roll Bar Center Set
This center roll bar set offers robust plastic construction to reinforce structural integrity and protection for 1/5 scale RC cars, including HPI ROFUN, Baja 5B/5T/5SC, and other listed models. It’s designed as a direct replacement that matches original specifications for straightforward installation and a precise fit. The central roll bar adds rigidity, helping prevent body flex and protecting internal components during hard impacts or flips, while preserving the visual scale appearance of the vehicle.
UURCSKY 4pcs Steel Hinge Pin Lower 5x96mm
Steel hinge pins designed for 1/5 ARRMA Kraton and Outcast platforms provide a durable replacement option for worn or bent pins. The 5x96mm size ensures compatibility with the suspension and chassis assemblies, contributing to improved alignment and steering accuracy. Made from high-quality steel, these pins offer long-lasting performance under demanding use, reducing maintenance interruptions and ensuring consistent ride quality across rough terrains.
GPM Aluminum 7075-T6 Motor Heatsink
This dual-implementation heatsink uses 7075-T6 aluminum to maximize motor cooling for 1/5 Kraton 8S BLX setups. The kit includes a fan mount and integrated frame cooling features to improve airflow around the motor, helping sustain performance during long sessions or high-heat runs. Proper cooling is essential for maintaining motor efficiency and longevity in demanding off-road and high-speed conditions.
Atomik RC Alloy Ultra Shock Cap
Atomik RC’s alloy shock cap offers precise CNC-machined fitments for factory-spec performance in compatible models. Manufactured from hardened 6061 aluminum, these caps deliver lightweight strength and repeatable damping consistency. Available in multiple colors, they suit a range of 1/10 and specialized 1/5 scale models, ensuring a durable upgrade that can tolerate repeated shock cycling and rugged use.
Buying Guide: Key Purchase Considerations
- Compatibility: Verify model numbers and chassis compatibility (e.g., 1/5 Kraton, ARRMA 8S, or specific HPI/Traxxas chassis) before purchasing.
- Material and Durability: Aluminum alloys (7075-T6, 6061-T6) offer weight savings and enhanced heat resistance, while steel hinges add maximum strength for high-stress use.
- Maintenance and Adjustability: Shocks with threaded collars and adjustable springs enable fine-tuning of ride height and damping. Consider ease of oil refill or maintenance intervals.
- Cooling and Performance: Heatsinks and active cooling (fans) improve motor longevity under heavy use. Check for fit around existing motor housings.
- Installation and Fit: Direct replacement parts simplify installation. Look for parts designed to match OEM bolt patterns and dimensions.
- Aesthetics and Color: Some upgrades offer color choices for customization while maintaining performance; ensure color options don’t affect fitment.
- Maintenance Schedule: Regular checks on pins, hinges, and shock caps prevent wear-induced performance drops; plan replacement intervals based on usage.
These selections provide a balanced mix of performance-focused upgrades and structural components for 1/5 scale RC rollers. When selecting upgrades, prioritize those that directly affect ride stability, heat management, and chassis integrity to achieve more consistent performance during demanding runs.
