Traxxas Chassis Conversion Kit, TRX-4 (Short to Long wheelbase)
Best for: RC hobbyists who want to extend the TRX-4’s wheelbase for improved stability on uneven terrain. This kit includes rear upper & lower suspension links, front & rear shock towers, and a long female half shaft, enabling a genuine long-wheelbase configuration. The setup provides better ground clearance and a steadier ride on rough tracks. Use this if your RC model benefits from a longer stance and you’re comfortable assembling multiple components.
Why chosen: It directly addresses the short-to-long wheelbase need with a complete set of essential chassis parts. The kit is designed to preserve alignment and handling characteristics while expanding the vehicle’s footprint. A potential limitation is the increased weight and space requirements of a longer chassis, which may affect maneuverability in tight spaces.
Traxxas 8058 Chassis Conversion Kit TRX-4 (Long to Short wheelbase)
Best for: TRX-4 owners who need a quick and complete transition back to a shorter wheelbase for agility in tight spaces or obstacle courses. The kit includes rear suspension links, inner fenders, a short female half shaft, and a battery tray with multiple fastener options to support the conversion. Choose this if you expect frequent wheelbase changes or prefer a compact, nimble setup for racing or technical trails.
Why chosen: It provides a thorough short-wheelbase conversion with several components that help maintain chassis geometry. Limitation: It may require additional alignment adjustments and compatible body mounts when switching back and forth between wheelbases.
Non-MDS Camshaft Lifters Kit for 5.7L Hemi Engine
Best for: Automotive enthusiasts upgrading engine valvetrain components where standard MDS lifters are being replaced with solid lifters for longer-lasting performance. This kit is more about engine internals than wheelbase or shaft length conversions. Consider this if you are restoring or upgrading a compatible 5.7L Hemi and need precise timing parts.
Why chosen: It targets a standard configuration conversion in the engine, offering a full camshaft and related parts to maintain proper oil pressure and timing. Limitation: It is engine-specific and not a direct match for power tool shaft conversions.
FORESTER Carbide Tip Brush Cutter Blade – 8in x 40 Teeth
Best for: Trimmer users seeking a straightforward conversion to brush cutter capability, especially when cutting thick brush and weeds. This blade fits most straight-shaft trimmers with a 1-inch arbor and includes a 20mm bushing. Choose this if you want a robust upgrade without a complex kit install.
Why chosen: The carbide tips provide longer life and faster cutting through tough material. Caution: A conversion kit is sold separately, so ensure you have the proper adapter and safety fittings before installation.
FORESTER Chainsaw Brush Cutter Blade + File Set – 9in x 20 Teeth
Best for: Users needing heavy-duty brush cutting with a straight-shaft trimmer, particularly where the conversion kit is already in place or required for a brush cutter head. It features a 1-inch arbor hole and a 20mm bushing for compatibility. Opt for this when you face saplings or thick brush that a standard blade can’t handle.
Why chosen: The chainsaw-style teeth deliver high cutting power and speed. Limitation: It requires a compatible conversion kit and may demand higher RPM and operator caution for safety.
FORESTER Carbide Tip Brush Cutter Blade – 8in x 32 Teeth
Best for: Mid-range brush clearance where a balance of speed and durability is needed on straight-shaft trimmers. The blade uses carbide tips for longer life and a 1-inch arbor with a 20mm bushing for compatibility. Choose this if you want a versatile option that blends cutting speed with durability.
Why chosen: Carbide tips extend blade life and maintain sharpness under tough materials. Caution: Ensure proper installation and a compatible conversion kit to avoid safety hazards during use.
Buying Guide: Short To Long Shaft Conversion Kit Considerations
What is your primary goal?
Decide whether you need more stability and wheelbase for RC vehicles or a longer reach for outdoor tool applications. Traxxas kits focus on vehicle chassis geometry, while FORESTER blades focus on changing cutting capabilities for trimmers and brush cutters.
Compatibility and installation
Check that the kit matches your model’s make and model year. For blade-based conversions, confirm arbor size (1-inch) and any required adapters or conversion kits sold separately. Proper fit prevents unsafe operation and ensures optimal performance.
Performance expectations
Longer wheelbases improve stability on rough terrain but may reduce agility in tight spaces. Carbide-tipped blades deliver longer life and faster cuts but require engine or trimmer compatibility and potentially more powerful equipment to handle increased load.
Safety and maintenance
Follow manufacturer safety instructions, wear protection, and perform routine checks after installation. Some conversions demand more frequent maintenance, alignment adjustments, or lubrication due to altered stress points.
Buying decision quick-reference
- RC chassis: prefer Traxxas TRX-4 short-to-long or long-to-short kits for precise wheelbase changes.
- Outdoor power tools: choose carbide blade variants for tough brush; verify arbor and adapter availability.
- Multiple wheelbase needs: Traxxas kits offer broader options but may require additional components.
FAQ
- What is a short-to-long wheelbase conversion kit used for?
– It adapts a chassis to a longer wheelbase for stability and ground clearance, often used in RC models to improve off-road performance. - Are conversion kits universal for blades and trimmers?
– No. Check arbor size (usually 1 inch) and compatibility with your trimmer model. Some kits require adapters or a dedicated conversion kit sold separately. - Can I switch back from long to short wheelbase easily?
– Some kits support both configurations, but it may require reassembly and alignment; refer to the kit’s included components for specifics. - Do carbide tipped blades require special safety precautions?
– Yes. Use protective gear, ensure proper installation, and avoid overloading the tool to prevent kickback or damage. - What’s the best option for rugged terrain?
– For RC chassis, Traxxas long-wheelbase kits improve stability; for brush cutting, carbide-tipped blades provide durability in dense growth. - Do these kits affect warranty?
– Conversion work can impact warranties; consult the manufacturer’s policy for your specific model.
