Overview
Take your PowerStroke shocks to the next level with Pro-Line's Spring Assortment, the essential tuning component for any serious RC enthusiast running 1/10 scale off-road vehicles in the UK. Whether you're competing in organised RC races or enjoying weekend bashing sessions, this comprehensive spring kit gives you unprecedented control over your vehicle's suspension geometry and handling characteristics. Now you can adjust ride heights and dual-rate spring rates almost infinitely with these colour-coded springs, allowing you to fine-tune your RC car's performance to match any track condition, terrain type or driving style.
The PRO 1/10 PowerStroke Shock Front Spring Assortment is purpose-built for Pro-Line's PowerStroke shock system, one of the most respected suspension platforms in competitive 1/10 RC racing. This isn't a basic spring pack—it's a complete tuning solution that empowers you to experiment with different spring rate combinations without purchasing multiple individual kits. For RC car UK enthusiasts who demand precision handling and competitive performance, this assortment is an invaluable addition to your spares box and suspension tuning arsenal.
Designed and manufactured by Pro-Line Racing, a recognised authority in high-performance RC suspension components, this spring assortment delivers the quality and consistency that competitive racers and serious hobbyists expect. With twelve premium springs colour-coded by rate, you'll have the flexibility to optimise your suspension setup for tarmac circuits, loose dirt tracks, grass fields or mixed terrain courses.
Key Features
- Six Primary Springs (black/short) — The primary springs work in conjunction with the secondary springs to provide progressive spring rates that absorb initial impacts whilst maintaining consistent support throughout the suspension stroke, giving you smooth ride quality and predictable handling on rough terrain.
- Six Secondary Springs (silver/long) — These longer secondary springs work alongside the primary springs to create a dual-rate suspension system, allowing the shock to compress more easily initially but increasing stiffness as the suspension compresses further, which provides both comfort and control.
- Colour Coded Stripes for Easy Identification — Each spring is marked with colour-coded stripes that correspond to specific spring rates, making it quick and simple to identify which springs you're using and to swap between different combinations during tuning sessions without confusion or mix-ups.
- Comprehensive Spring Rate Chart Included — Pro-Line provides a detailed spring rate chart showing all possible combinations of primary and secondary springs and their effective rates, eliminating guesswork and allowing you to make informed tuning decisions based on your specific setup requirements and track conditions.
- Infinite Tuning Possibilities — By combining different primary and secondary spring rates, you can achieve virtually unlimited suspension configurations, giving you the flexibility to dial in the perfect setup for your specific vehicle, driving style, track surface and weather conditions without needing to purchase additional components.
- Compatible with PowerStroke Shocks — These springs are specifically designed to work with Pro-Line PowerStroke shock absorbers, ensuring perfect fitment, consistent performance and the engineering integration that comes from matched components designed together.
- High Quality Construction — Manufactured to Pro-Line's exacting standards, these springs deliver consistent rate specifications and durability that will withstand the demanding demands of competitive racing and intense bashing sessions.
Technical Performance
The PRO 1/10 PowerStroke Shock Front Spring Assortment represents the pinnacle of suspension tuning flexibility for 1/10 scale RC cars. This kit addresses one of the most critical aspects of RC vehicle performance—suspension geometry and spring rates—which directly affects how your car handles, accelerates, brakes and corners. The dual-rate spring system is a sophisticated engineering solution that provides progressive resistance: the springs start soft to absorb small bumps and maintain traction over rough terrain, then become progressively stiffer as they compress, preventing the suspension from bottoming out during hard landings or aggressive driving. The colour-coded identification system is more than just a cosmetic touch; it's a practical engineering feature that prevents setup errors and allows drivers to quickly implement different tuning strategies during practice sessions or race events. The inclusion of a comprehensive spring rate chart transforms this from a simple components kit into a complete tuning reference system, enabling you to make precise adjustments based on data rather than guesswork. Whether you're running your PowerStroke shocks on a tight indoor carpet track, a fast outdoor asphalt circuit, a technical dirt course or mixed-terrain off-road terrain, this assortment gives you the tools to optimise your suspension for maximum performance. The engineering quality reflects Pro-Line Racing's reputation as one of the most respected manufacturers of high-performance RC suspension components, with springs manufactured to precise specifications that deliver consistent performance across multiple use cycles.

Frequently Asked Questions
- Will this spring assortment work with my PowerStroke shocks? — Yes, this assortment is specifically designed for Pro-Line PowerStroke shock absorbers on 1/10 scale RC vehicles. The springs are engineered to fit perfectly and deliver the performance Pro-Line intended when used with genuine PowerStroke shocks.
- How do I know which spring combination to use for my track conditions? — Pro-Line includes a detailed spring rate chart that shows every possible combination of primary and secondary springs and their effective rates. Start with a mid-range combination and make small adjustments based on how your car handles, gradually finding the optimal setup for your specific track surface, weather conditions and driving style.
- What's the difference between primary and secondary springs? — Primary springs (the shorter black springs) provide the initial suspension support and absorb the first impact of bumps and jumps. Secondary springs (the longer silver springs) work in parallel and provide progressive support as the suspension compresses further, creating a dual-rate system that combines comfort with control.
- Can I mix and match springs from different kits? — Yes, the modular design allows you to experiment with different combinations of primary and secondary springs from this assortment. This flexibility is the entire purpose of the kit—to give you virtually unlimited tuning options without needing to purchase multiple separate components.
- How often will I need to replace these springs? — Springs are durable components that typically don't wear out during normal use. You may want additional springs for racing if you want to have multiple pre-tuned setups ready, but a single assortment should last through many seasons of use with proper care and storage.
- Is this suitable for beginners? — This is an intermediate to advanced tuning component rather than a beginner's product. However, beginners can use it successfully by starting with middle-range spring combinations and following the included rate chart. It's an excellent learning tool that teaches how suspension tuning affects vehicle performance.
- What makes this better than single spring replacements? — Rather than buying springs one at a time or in matched pairs, this assortment gives you a complete range of options in a single kit, saving money and providing the variety needed for comprehensive suspension tuning and experimentation across different track conditions.
