Overview
The PRO 1/6 Dual Stage Front/Rear 2.9 inch Crawling Foam (2) represents a significant upgrade for any serious RC crawler enthusiast in the UK. These foam inserts are engineered specifically for large scale rock crawlers and are arguably the single biggest performance upgrade you can make to your vehicle, short of purchasing new tyres altogether. Designed and manufactured by Pro-Line, these 2.9" foam inserts are the newest and largest addition to their popular line of rock crawling performance foam products, and they have been engineered from the ground up to work seamlessly with the Axial SCX6 platform and compatible 2.9" crawler tyres.
Whether you're a weekend basher tackling rocky terrain, a competition-focused crawler seeking marginal gains in grip and control, or an experienced RC hobbyist looking to optimise your SCX6 setup, these dual stage foam inserts will transform your vehicle's performance on technical terrain. The combination of advanced materials, intelligent design and Pro-Line's reputation for quality means you're investing in a product that will deliver consistent performance through many rugged adventures. For anyone serious about rock crawling with their 1/6 scale RC vehicle in the UK, these foams are an essential upgrade that addresses one of the most critical aspects of crawler performance.
The technology behind these foams is genuinely innovative. Rather than using a single foam compound, Pro-Line has engineered a dual stage system that combines the best properties of two different foam types to create a product that excels in grip, sidewall support and durability. This is the kind of performance-focused thinking that separates premium RC products from standard offerings, and it's why these foams have become the preferred choice for serious crawlers across the UK and beyond.
Key Features
- Dual Stage Foam Construction — The inner layer features lightweight and waterproof blue closed cell foam whilst the outer layer is made from soft open cell foam, creating an incredibly effective two-part system that maximises both grip and structural support simultaneously.
- Contoured Inner Closed Cell Insert — The inner foam insert is completely contoured to precisely match the shape of Pro-Line's 2.9" SCX6 rock crawling tyres, ensuring perfect fitment and optimal performance that improves both tyre durability and visual appearance.
- Maximum Sidewall Support — The inner closed cell foam layer provides unmatched sidewall support, which is essential for maintaining control and stability when side-hilling on steep terrain, a critical aspect of competitive rock crawling.
- Enhanced Grip and Traction — The soft outer foam layer delivers maximum grip and traction on rocky surfaces whilst the inner closed cell foam ensures the sidewall remains fully supported, creating a perfectly balanced system for all crawling conditions.
- Exceptional Durability — These foams are engineered to be extremely durable and waterproof, capable of withstanding the demands of serious rock crawling without deteriorating, meaning they'll last through countless rugged adventures.
- Improved Appearance — Beyond pure performance, these foams are finished in a unique Pro-Line blue colour with white accents, enhancing the visual appeal of your crawler whilst delivering serious performance benefits.
- Universal SCX6 Compatibility — Designed to work with Pro-Line's Hyrax XL crawler tyres (PRO1018614) and the standard Axial SCX6 stock tyre (AXI45000), as well as other 2.9" SCX6 compatible tyres on the market.
- Front and Rear Usage — This pair of foams can be used on either the front or rear axles of your SCX6, providing versatility in your setup options and allowing you to experiment with different configurations.
Technical Performance
The engineering excellence built into these foam inserts is evident in every detail. Pro-Line has invested considerable research and development into creating a dual stage foam system that addresses the fundamental challenges of large scale rock crawling. The inner closed cell foam layer is manufactured from lightweight blue closed cell material that resists water absorption, a critical property when you're regularly traversing wet rocky terrain. This inner layer provides the structural integrity needed to prevent tyre collapse on extreme side-hills whilst maintaining the precise contoured shape that matches Pro-Line's 2.9" tyres perfectly. The outer soft open cell foam layer is where the magic happens from a grip perspective, as this softer material conforms to rock surfaces and provides maximum traction without sacrificing the sidewall support delivered by the inner layer. The combination of these two materials creates a foam system that simply performs better than single-stage alternatives on the market. The closed cell foam construction is inherently durable and will maintain its properties through countless sessions of demanding rock crawling, and the waterproof nature of the materials means these foams won't degrade when exposed to wet conditions. The contoured design ensures these foams fit perfectly within Pro-Line's 2.9" SCX6 tyres, eliminating gaps that would otherwise reduce performance and appearance. For serious RC crawler enthusiasts in the UK seeking to maximise their vehicle's performance on technical terrain, these foams represent a genuinely significant upgrade that delivers measurable improvements in grip, control and durability.

Frequently Asked Questions
- What is the difference between dual stage foam and standard single-stage foam? — Dual stage foam combines two different foam materials optimised for different purposes: the inner closed cell foam provides lightweight structural support and sidewall integrity, whilst the outer soft foam delivers maximum grip and traction. Single-stage foams are a compromise between these properties, whereas dual stage foams excel at both, making them superior for serious crawling.
- Are these foams waterproof? — Yes, the inner closed cell foam layer is completely waterproof, which is essential for rock crawlers that regularly traverse wet terrain. The closed cell construction prevents water absorption and deterioration, ensuring consistent performance in all weather conditions.
- Will these foams work with my standard SCX6 tyres? — These foams are designed to fit Pro-Line's 2.9" SCX6 rock crawling tyres such as the Hyrax XL (PRO1018614) and the Axial SCX6 stock tyre (AXI45000), as well as other compatible 2.9" SCX6 tyres. The contoured design ensures perfect fitment with these specific tyre profiles.
- Can I use these foams on both front and rear? — Yes, this pair of foams is suitable for either front or rear axle positions, giving you flexibility to experiment with your vehicle's setup and balance. You can run them front only, rear only, or both front and rear depending on your preferences and terrain.
- How long will these foams last? — Pro-Line's closed cell foams are engineered to be extremely durable and will last through many rugged adventures. The quality of the materials and construction means these foams will maintain their properties far longer than cheaper alternatives, making them an excellent long-term investment.
- What makes these foams better for side-hilling? — The inner closed cell foam provides unmatched sidewall support, which is critical for side-hilling performance. When your crawler is tilted at extreme angles on rocky terrain, this sidewall support prevents tyre collapse and maintains control, allowing you to tackle steeper obstacles safely.
- Do I need to buy anything else to use these foams? — These foams fit directly inside compatible 2.9" SCX6 crawler tyres. You'll need the appropriate tyres to use these foams, such as Pro-Line's Hyrax XL or Axial's standard SCX6 tyre. Once you have the tyres, simply insert these foams and you're ready to crawl.
- Are these a good upgrade for beginners? — Whilst beginners can certainly use these foams, they're specifically engineered for serious rock crawlers who want to maximise performance on technical terrain. If you're new to RC crawling, starting with your vehicle's standard setup is fine, but as you progress and tackle more challenging terrain, upgrading to quality dual stage foams like these will deliver noticeable improvements in handling and grip.
