Overview
The Pro-Line 1/10 Dual Stage 2.2 inch Rock Crawling Foam Inserts represent the next generation of performance foam technology for serious rock crawlers and RC enthusiasts across the UK. Whether you're tackling challenging terrain on the weekends or competing in RC crawler events, these precision-engineered foam inserts deliver the grip, support and durability that separate competitive setups from casual builds. Pro-Line has engineered these inserts specifically for their 2.2" XL sized rock crawling tyres, ensuring perfect fitment and optimised performance every time you hit the trail.
Rock crawling demands more from your RC car's tyres and inserts than any other discipline. You need sidewall support to maintain control on extreme side-slopes, grip to navigate over rocks and obstacles, and durability to withstand countless adventures without degradation. This is where Pro-Line's innovative Dual Stage Closed Cell foam technology makes all the difference. Unlike traditional single-stage foam inserts, Pro-Line's new design combines a tough inner closed cell foam with a soft outer foam layer, giving you the best of both worlds in a single insert. For RC car enthusiasts in the UK looking to upgrade their rock crawling setup or build a competitive rock crawler from scratch, these foam inserts are an essential component that will transform your vehicle's on-terrain performance and reliability.
Available in Pro-Line's distinctive blue and white colour scheme, these foam inserts aren't just engineered for performance—they're designed to look the part too. If you're serious about rock crawling with your 1/10 scale RC car and want inserts that will perform consistently across multiple seasons of challenging terrain, the Pro-Line 1/10 Dual Stage 2.2 inch Rock Crawling Foam Inserts are the upgrade you've been waiting for.
Key Features
- Dual Stage Closed Cell Foam Construction — This innovative design combines a lightweight and waterproof blue closed cell foam inner layer with a soft open cell foam outer layer, providing unmatched performance compared to traditional single-stage foam inserts. The dual stage design means you get maximum sidewall support from the inner layer whilst enjoying maximum traction from the soft outer layer, a combination that's essential for serious rock crawling.
- Perfectly Contoured to Pro-Line 2.2" XL Tyres — Every aspect of these foam inserts has been precisely engineered to match the shape and dimensions of Pro-Line's 2.2" XL rock crawling tyres, ensuring perfect fitment and optimised performance every time you use them. This contoured design improves both tyre performance and the overall appearance of your finished rock crawler.
- Exceptional Sidewall Support — The inner closed cell foam layer provides unmatched sidewall support, which is critical when side-hilling or navigating extreme terrain angles. This support keeps your tyres stable and prevents collapse during aggressive rock crawling manoeuvres, giving you confidence on the most challenging obstacles.
- Maximum Traction with the Soft Outer Foam — The soft outer foam layer is specifically designed to maximise grip and traction across all terrain types, from rocky trails to muddy slopes. This soft material maintains contact with the ground whilst being fully supported by the inner closed cell foam, preventing bottom-out and ensuring consistent performance throughout long crawling sessions.
- Superior Durability for Extended Use — Pro-Line's new Dual Stage Closed Cell foam inserts are engineered to be extremely durable, designed to last through many rugged adventures without degradation or compression. You can invest in these inserts with confidence, knowing they'll maintain their performance characteristics across multiple seasons of use.
- Lightweight and Waterproof Design — The blue closed cell foam inner is inherently lightweight, keeping your 1/10 scale RC crawler's unsprung weight to a minimum, whilst the waterproof construction means you can confidently take your rock crawler through stream crossings, water features and wet terrain without worrying about foam saturation or deterioration.
- Improved Side-Hilling Performance — By combining soft outer foam for maximum grip with fully supported sidewalls from the inner closed cell foam, these inserts deliver significantly improved side-hilling performance compared to standard foam inserts. You'll notice the difference immediately when tackling steep slopes and extreme angles.
- Enhanced Appearance with Distinctive Blue and White Colour — The unique Pro-Line blue and white colour scheme gives your rock crawler a professional, finished appearance that stands out from basic builds. These inserts aren't hidden inside the tyres—they contribute to your crawler's overall aesthetics as well as its performance.
Technical Performance
These 1/10 scale foam inserts represent a significant engineering advancement in rock crawling insert design. The dual stage construction utilises a closed cell foam inner layer manufactured from lightweight, waterproof blue foam that provides the structural support needed for extreme terrain negotiation. The outer layer employs soft open cell foam specifically chosen for its superior grip characteristics and ability to conform to uneven terrain surfaces. Together, these materials are precisely contoured to match Pro-Line's 2.2" XL tyre profile, ensuring that the foam maintains consistent contact with the tyres' inner walls throughout the entire range of flex and compression experienced during rock crawling. This engineering approach eliminates the performance compromises associated with traditional single-stage foam inserts. The closed cell inner foam provides exceptional sidewall rigidity whilst the outer soft foam layer delivers the compliance and traction needed for maximum grip on rocks, roots, and obstacles. The waterproof construction of the inner closed cell foam means you can confidently use these inserts in wet conditions, stream crossings, and muddy terrain without concerns about water absorption or degradation. The overall design philosophy prioritises durability without sacrificing performance—these inserts are built to withstand repeated compression cycles, rocky impacts, and aggressive terrain without compressing out or losing their shape. For UK-based RC crawling enthusiasts building competition-grade or serious hobby-level rock crawlers, the engineering quality and performance characteristics of these foam inserts represent excellent value and a meaningful upgrade over standard alternatives.

Frequently Asked Questions
- What makes these foam inserts different from standard rock crawling foam? — The key difference is the innovative dual stage construction. Traditional foam inserts use a single material throughout, which means you have to compromise between sidewall support and grip. Pro-Line's design uses a tough inner closed cell foam for sidewall support and a soft outer foam for maximum traction, giving you the best of both worlds. The inner foam is also waterproof and lightweight, and the entire insert is perfectly contoured to match Pro-Line 2.2" XL tyres for optimised performance.
- Will these foam inserts work with tyres other than Pro-Line brands? — Yes, these inserts are designed to fit Pro-Line's 2.2" XL rock crawling tyres, but they will also fit other XL size 2.2" tyres such as Interco TSL SX Super Swamper XL and Flat Iron XL models. If you're using a different brand of XL 2.2" tyres, we recommend checking the dimensions match before purchasing.
- Can I use these foam inserts in wet conditions and stream crossings? — Absolutely. The inner closed cell foam layer is specifically designed to be waterproof, making these inserts ideal for rock crawling adventures that involve water features, stream crossings, and muddy terrain. You won't experience water absorption or degradation from wet use.
- How long will these foam inserts last before I need to replace them? — Pro-Line's Dual Stage Closed Cell foam inserts are engineered for exceptional durability and are designed to maintain their performance characteristics through many rugged adventures. The exact lifespan depends on your usage intensity and terrain, but these inserts are built to last significantly longer than standard alternatives. The durable construction means you won't experience premature compression or degradation even with frequent intensive use.
- What makes the dual stage design better for side-hilling? — When side-hilling at extreme angles, your tyres experience significant sideways forces that can cause standard foam inserts to collapse or deform, compromising control and grip. The inner closed cell foam provides exceptional sidewall support that keeps your tyres rigid and stable during these manoeuvres, whilst the soft outer foam maintains contact with the ground for grip. This combination delivers significantly improved side-hilling performance compared to single-stage foam inserts.
- Are these foam inserts suitable for beginners? — Yes, these foam inserts are suitable for rock crawlers of all skill levels. If you're building your first rock crawler with 2.2" XL tyres, these Pro-Line inserts represent an excellent choice that will deliver reliable performance and durability from day one. The precise fit to Pro-Line tyres means installation is straightforward, and the superior engineering means you'll immediately notice improved performance compared to basic foam alternatives.
