Key Features

• 76mm Length — The 76mm size is specifically designed to fit ARRMA models in the Kraton range, ensuring perfect compatibility without any modification or fitment issues. This standard length maintains your vehicle's intended suspension geometry.
• Medium Spring Rate (73.6gf/mm) — The medium rating provides a balanced compromise between softness and stiffness, making these springs suitable for a wide variety of driving conditions and skill levels. A medium spring rate is an excellent starting point for tuning your suspension, allowing you to dial in comfort and control.
• Pair of Springs — This pack includes two springs, which is the standard quantity needed to replace both front or both rear shock springs on your ARRMA RC vehicle. Having matched pairs ensures consistent suspension performance across your chassis.
• Genuine ARRMA OEM Component — As official ARRMA parts, these springs are manufactured to exact specifications and quality standards, guaranteeing compatibility and durability. OEM components eliminate any guesswork about fitment or performance characteristics.
• Quick Suspension Tuning — Swapping shock springs is one of the fastest ways to adjust your vehicle's handling without needing tools or technical knowledge. You can literally change your suspension setup in seconds, making this ideal for track testing different configurations.
• Affordable Spares Solution — Whether you're replacing damaged springs or building up a collection of spare parts for your RC car, these springs represent excellent value for money. They're an inexpensive way to maintain your vehicle or experiment with suspension tuning.

Technical Performance

The ARRMA Shock Spring 76mm M 73.6gf/mm combines precision engineering with straightforward functionality that appeals to RC enthusiasts of all levels. The 73.6gf/mm spring rate falls into the medium category, making it ideal for general-purpose RC driving across both on-road and off-road applications. In practical terms, this means the springs provide enough compliance to absorb bumps and maintain traction, whilst remaining stiff enough to prevent excessive body roll during cornering and aggressive manoeuvres. The 76mm length is matched to ARRMA's engineering specifications, particularly for vehicles in the Kraton lineup, ensuring that when installed they maintain the correct ride height and suspension geometry that ARRMA engineers designed into the chassis. The springs are manufactured from high-quality steel using industrial processes that ensure consistent spring rate across the pair — crucial for balanced vehicle handling. Unlike aftermarket springs that may vary from pair to pair, these genuine ARRMA components are produced to strict tolerances, meaning you can swap them with confidence that your suspension will perform consistently. The medium spring rate makes these springs particularly versatile; they're soft enough for comfort on rough surfaces and hard enough for controlled handling on technical tracks, making them suitable whether you're using a brushless RC buggy, a stadium truck, or exploring the growing world of competitive RC racing in the UK. These springs are a consumable item in the RC hobby — with regular use and aggressive driving, springs can weaken or develop permanent bends — so having spares ensures you always have fresh springs ready to maintain peak suspension performance.

Frequently Asked Questions

• What vehicles are these ARRMA shock springs compatible with? — These 76mm medium spring rate springs are designed specifically for ARRMA vehicles, particularly the Kraton range. The 76mm length is ARRMA's standard shock spring size. Before purchasing, check your vehicle's manual or parts diagram to confirm it uses 76mm springs, as ARRMA produces models with different shock spring sizes.
• How do I know if I need to replace my shock springs? — Shock springs should be replaced if they appear visibly damaged, bent, or permanently deformed, or if your suspension feels too soft or bouncy compared to when the vehicle was new. Springs weaken over time with use, so many RC enthusiasts replace springs regularly as part of maintenance, especially if they bash hard or race competitively.
• What does the 73.6gf/mm spring rate mean? — This number represents the spring rate, measured in grams-force per millimetre of compression. Essentially, it tells you how stiff the spring is. Higher numbers mean stiffer springs (for hard, fast tracks), lower numbers mean softer springs (for rough terrain or comfort). The 73.6gf/mm medium rate is a versatile middle ground suitable for most driving situations.
• Can I use different spring rates on front and rear? — Yes, many RC drivers use different spring rates on the front and rear axles to fine-tune balance and handling. A softer front and stiffer rear is a common setup for racing. Experiment with different combinations to see what works best for your driving style and the conditions you race in.
• How do I install these shock springs? — Installation involves removing your shock absorber from the vehicle, carefully unloading the old spring (using a spring compressor tool), and sliding the new spring into place. If you're not confident doing this yourself, many local RC clubs and hobby shops offer fitting services. Always ensure springs are seated correctly and fully compressed before reinstalling the shock on your vehicle.
• Are these suitable for beginners? — Absolutely. The medium 73.6gf/mm spring rate is an excellent starting point for anyone learning about RC suspension tuning. These aren't specialist racing springs — they're general-purpose spares that work well across a range of driving styles and conditions, making them perfect for beginners and experienced drivers alike.
• How often should I replace my shock springs? — With casual use, shock springs can last quite a long time, but competitive drivers or those who bash hard might replace them every few months. If you notice your suspension feels different or your vehicle doesn't handle like it used to, fresh springs might be the solution.
