Overview
The RC4WD 4 Link Kit for Trail Finder 2 Rear Axle (Z-S0603) is a premium suspension upgrade designed specifically for owners of the RC4WD Trail Finder 2 scale crawler. This conversion kit allows you to replace the stock leaf-spring rear suspension setup with a more advanced and capable 4-link suspension system, dramatically improving your RC crawler's performance both on and off the trail. Whether you're a dedicated Trail Finder 2 enthusiast looking to enhance your rig's suspension geometry, or a UK RC hobbyist seeking to unlock greater articulation and control over rocky terrain, this kit delivers the engineering quality and precision that RC4WD is renowned for throughout the RC community.
The 4-link suspension design offers superior advantages over traditional leaf-spring setups when it comes to maintaining consistent axle control during extreme articulation, allowing your Trail Finder 2 to maintain better traction and stability when tackling challenging obstacles. This makes the kit an excellent choice for serious scale RC crawler enthusiasts in the UK who demand competition-grade suspension performance from their rigs. The kit includes everything you need to complete the conversion, from CNC-machined metal components to all necessary fasteners, plastic rod ends and a comprehensive instruction manual to guide you through the installation process.
RC4WD has engineered this 4-link conversion to be a bolt-on upgrade that respects the original Trail Finder 2 geometry whilst introducing the precision control characteristics that serious RC crawlers demand. The combination of premium materials, precision manufacturing and thoughtful design makes this one of the most sought-after suspension upgrades available for Trail Finder 2 owners throughout Europe.
Key Features
- CNC Machined Metal Components — The kit features precision CNC-machined metal parts that provide superior strength, durability and accuracy compared to plastic alternatives, ensuring your suspension maintains its performance characteristics through countless hours of crawling and bashing on UK trails and rocks.
- Complete 4-Link Suspension System — This is a fully-featured 4-link rear suspension conversion that replaces your stock leaf-spring setup with a modern suspension design that provides independent control of axle positioning, dramatically improving articulation and wheel placement on uneven terrain.
- Includes All Required Hardware — Rather than requiring you to source fasteners separately, RC4WD has thoughtfully included every bolt, screw, spacer and locknut needed to complete the conversion, saving you time and ensuring you have the correct specification parts for your build.
- Plastic Rod Ends for Smooth Operation — The kit comes equipped with both short bent and medium straight plastic rod ends (8 pieces total) that provide smooth articulation while maintaining durability and minimising wear on critical suspension pivot points.
- Multiple Link Lengths for Geometry Options — Two 81mm links and two 75mm links are included, offering you flexibility in fine-tuning your suspension geometry to suit your driving style and terrain preferences.
- Left and Right Mounting Hardware — The kit includes dedicated 4-link truss parts and left/right mount hardware, ensuring a symmetrical and balanced suspension setup that performs consistently across your entire crawling experience.
- Comprehensive Instructions Included — A detailed instruction manual walks you through every step of the conversion process, making this a realistic project for experienced builders and those new to RC suspension upgrades.
- Made for Trail Finder 2 Compatibility — Engineered specifically for the RC4WD Trail Finder 2 rear axle, this kit offers perfect fitment and integration without modifications to your existing chassis or components.
Technical Performance
The RC4WD 4 Link Kit represents a significant engineering upgrade from the stock Trail Finder 2 suspension. The 4-link design fundamentally changes how your rear axle responds to obstacles and uneven terrain, allowing the axle to maintain consistent contact with the ground whilst articulating through greater ranges of motion. This is achieved through the precise geometry created by the two 81mm main links and two 75mm secondary links, which work together to control axle movement whilst minimising binding and friction. The inclusion of metal construction throughout the kit ensures that the suspension maintains its geometry and performance characteristics even under extreme articulation loads, a critical requirement for serious scale crawlers operating on technical UK terrain. The plastic rod ends (a total of 8 pieces in both bent and straight configurations) provide the necessary pivot points whilst remaining light enough not to add excessive unsprung weight to the rear axle. All fastening hardware specified in the kit uses metric sizing (M3 series) with both button head and countersunk options to suit different mounting requirements, and the inclusion of at least one locknut demonstrates RC4WD's attention to preventing fastener loosening during aggressive driving. The truss structure ties everything together with a robust framework that distributes loads efficiently and resists bending or twisting during high-articulation scenarios. This is professional-grade suspension engineering scaled appropriately for the Trail Finder 2, delivering measurable improvements in traction, stability and obstacle negotiation capability compared to the stock leaf-spring design.

Frequently Asked Questions
- Is the RC4WD 4 Link Kit suitable for beginners? — This kit is best suited for intermediate to advanced RC builders with some suspension knowledge and experience. The conversion requires careful assembly and understanding of suspension geometry, and whilst the included instructions are comprehensive, you should feel comfortable working with metric fasteners and precision components. If you're new to RC modifications, we'd recommend gaining some building experience first or consulting our expert team before attempting this upgrade.
- Will this kit work with my Trail Finder 2? — Yes, this kit is specifically engineered for the RC4WD Trail Finder 2 rear axle and provides a direct bolt-on conversion from the stock leaf-spring setup. The kit is designed to integrate seamlessly with your existing Trail Finder 2 chassis without modifications.
- What is a 4-link suspension and why is it better than leaf springs? — A 4-link suspension uses four arms (links) to control axle movement in multiple directions, providing superior articulation control, better wheel contact during extreme angles, and more predictable handling characteristics. Leaf springs are simpler but less capable during high-articulation scenarios. For serious RC crawling, the 4-link design is superior because it maintains better traction and allows the axle to follow terrain contours more precisely.
- Do I need any additional tools or parts to install this kit? — The kit includes all fasteners and components needed for the conversion. You will need basic tools such as metric hex wrenches, screwdrivers and possibly a small punch or hex key set. The instruction manual will specify exactly what you need. No additional RC parts are required.
- Can I use the original links to adjust ride height? — The kit includes two different link lengths (81mm and 75mm) which provide geometry options. Your specific setup will depend on your driving preferences and terrain. The instruction manual will guide you through these choices.
- How long does installation take? — Installation time varies depending on your experience level and familiarity with your Trail Finder 2. Most builders should expect 1-2 hours working methodically through the process. Take your time to ensure all fasteners are secure and geometry is correct before testing on terrain.
