Overview

The ARRMA Shock Set, Rear (2) is an essential replacement component for ARRMA RC enthusiasts across the UK who demand high-performance suspension systems. This assembled rear shock set provides ideal replacement parts for your kit-supplied items, whether you're running a 1/10 scale brushless monster truck, a 1/10 brushed short course truck, or an 1/8 scale buggy. If you're serious about RC car performance, having quality replacement shocks on hand is absolutely critical, as suspension components endure tremendous stress during high-speed bashing and competitive racing. The ARRMA Shock Set represents genuine, manufacturer-approved components that maintain the handling characteristics and durability your RC vehicle was engineered to deliver.

This shock set is perfect for the dedicated RC enthusiast who wants to maintain their ARRMA RC truck or buggy at peak performance levels. Whether you're replacing worn suspension components after months of intense off-road use, setting up a second shock configuration for different terrain conditions, or building a backup vehicle, this pre-assembled solution saves you valuable setup time. The rear shocks come ready to bolt directly onto your vehicle, making this an excellent choice for both experienced builders and those new to RC who want a straightforward upgrade path for their ready to run RC models.

Built with high-quality materials and pre-filled with shock oil, this rear shock set eliminates guesswork and gets you back on the track or trail faster. ARRMA's reputation for building robust, performance-oriented RC vehicles extends to their individual components, and these shocks reflect that commitment to quality. Compatible with a wide range of ARRMA 1/10 and 1/8 scale models including the BIG ROCK, GRANITE, SENTON and TYPHON families, this is a versatile suspension upgrade that works across multiple platforms.

Key Features

• Supplied Assembled Without Springs — These shocks arrive fully assembled and ready for installation, which means you save considerable time compared to building shocks from individual components. The assembled design allows you to choose your own springs based on your specific driving style, terrain preference, and vehicle setup, giving you complete customisation control without the hassle of assembling the shock body, piston and shaft yourself.
• Pre-filled with Shock Oil — Factory pre-filling with quality shock oil means the damping characteristics are optimised right out of the box, delivering consistent suspension performance immediately upon installation. This eliminates air bubbles and ensures smooth, predictable shock action from your very first run, which is especially important for maintaining vehicle stability during high-speed cornering and landings after jumps.
• High-Quality Materials — ARRMA uses premium materials throughout their shock construction, ensuring durability and longevity even under extreme bashing conditions. These materials withstand the repeated impacts, vibrations and stress cycles that come with aggressive driving, meaning your investment in quality shocks will serve you through countless sessions of RC racing and bashing.
• Spring Spacers Included for Ride Height Tuning — The inclusion of spring spacers provides a straightforward way to fine-tune your vehicle's ride height without requiring different spring sets. By adjusting spacer configuration, you can raise or lower the chassis to suit your driving conditions, optimise weight distribution, and achieve the exact ride height geometry your setup requires for maximum traction and stability.
• Ready to Bolt On After Spring Installation — Once you've selected and fitted your choice of springs, these shocks bolt directly onto your vehicle with no additional assembly, modifications or tuning required. This ready-to-install approach means even relatively new RC enthusiasts can complete a suspension upgrade without advanced technical knowledge or special tools.

Technical Performance

The ARRMA Shock Set, Rear represents precision engineering designed specifically for the demands of modern RC racing and recreational bashing. These are not generic shock absorbers but carefully calibrated suspension components engineered to work seamlessly with ARRMA's vehicle platforms. The pre-filled shock oil delivers consistent damping performance across varying temperature ranges and terrain conditions, which is essential for maintaining predictable handling whether you're running on smooth tarmac, loose dirt, or sandy terrain. The shock assembly itself incorporates high-quality internal components and seals that resist dirt ingress and maintain performance integrity even after extended use in dusty or wet conditions. The engineering behind these shocks reflects ARRMA's commitment to delivering components that can handle the punishment delivered by powerful brushless motors and high-capacity LiPo batteries that characterise modern RC vehicles. The compatibility list spans multiple ARRMA platforms including the BIG ROCK 223S and 3S brushless monster trucks, the GRANITE 223S and 3S brushless variants, the GRANITE 4X4 brushed models, the GRANITE BOOST 2WD brushed short course truck, the SENTON 3S and 4X4 short course trucks in both brushless and brushed configurations, the SENTON BOOST 2WD brushed variant, and the TYPHON 223S and 3S 1/8 scale buggies in both brushless and brushed forms. This broad compatibility makes the shock set a practical solution whether you're upgrading a single vehicle or maintaining a fleet of ARRMA RC models across different scales and power configurations.

What's in the Box

• 2 x Assembled Shock Absorber (rear shocks)

What You Need to Complete

• Springs: Either ARRMA part #AR330460 (64mm 0.61N/mm springs, also listed as 5.40lb/in) or ARRMA part #AR330539 (80mm 0.84N/mm springs, also listed as 7.43lb/in) — your choice depends on your desired suspension stiffness and ride height characteristics

Frequently Asked Questions

• Which ARRMA vehicles are compatible with this rear shock set? — This shock set fits a comprehensive range of ARRMA models including the 1/10 BIG ROCK series (223S and 3S brushless variants), the 1/10 GRANITE family (223S brushless, 3S brushless, 4X4 brushed, and GRANITE BOOST 2WD brushed), the 1/10 SENTON range (3S 4X4 brushless, 4X4 brushed, and SENTON BOOST 2WD brushed), and the 1/8 TYPHON buggy series (223S brushless, 3S brushless, 4X4 brushed, and TYPHON MEGA 665 brushed). This compatibility makes it an excellent choice for UK RC enthusiasts running multiple ARRMA vehicles.
• Do I need to assemble these shocks myself? — No, these shocks arrive fully assembled and require no assembly work. You simply need to select appropriate springs from the compatible options, fit those springs to the shock bodies, and then bolt the complete shocks onto your vehicle. This saves considerable time compared to building shocks from component parts.
• What springs do I need to fit to these shocks? — You must choose between two spring options: ARRMA #AR330460 (64mm springs rated at 0.61N/mm or 5.40lb/in) for softer suspension with higher ride height, or ARRMA #AR330539 (80mm springs rated at 0.84N/mm or 7.43lb/in) for stiffer suspension with lower ride height. Your choice depends on your driving style, terrain, and desired vehicle handling characteristics. The included spring spacers allow further fine-tuning of ride height once you've chosen your primary spring option.
• Are these shocks suitable for both beginners and experienced RC enthusiasts? — Yes, these shocks are suitable for drivers at all experience levels. The pre-assembled design makes installation straightforward for newer RC enthusiasts, whilst the customisation options with different spring choices and spacer configurations appeal to experienced builders and racers who want to dial in their suspension precisely.
• How do the spring spacers help with ride height adjustment? — Spring spacers sit on the shock shaft and compress against the spring itself. By adjusting the number or configuration of spacers used, you can effectively change the ride height of your vehicle without purchasing different spring sets. This provides a cost-effective way to fine-tune suspension geometry for different driving conditions or personal preference without major component changes.
• Why are these shocks pre-filled with shock oil? — Pre-filling with quality shock oil ensures that damping performance is optimised from the moment you bolt the shocks onto your vehicle. Factory-filled shocks eliminate air bubbles that could compromise suspension feel, and ensure consistent performance throughout your RC session without the need for additional fluid preparation or tuning.
