Key Features

• 7075-T6 Billet Aluminium Construction — This shock tower is milled from solid 7075-T6 billet, one of the strongest and most expensive aluminium alloys available in the RC hobby. This material choice ensures exceptional rigidity and durability, allowing the shock tower to resist flexing and deformation even during high-impact landings and aggressive driving, which is critical for maintaining consistent suspension geometry and handling characteristics on your RC monster truck.
• Dark Titanium Anodised Finish — The dark titanium anodising provides more than just visual appeal; this hard anodised surface resists corrosion, scratches and wear far better than standard composite parts, ensuring your Sledge maintains its premium appearance while delivering superior long-term durability in outdoor driving conditions across the UK.
• Beveled Edges with Two-Tone Look — The machined beveled edges create a distinctive two-tone visual effect that demonstrates the premium craftsmanship of this component, giving your Sledge a competition-grade appearance that reflects the high-performance engineering within.
• Laser-Etched Logo — The Traxxas logo is laser-etched directly into the aluminium for maximum impact and permanence, ensuring the branding remains visible and crisp even after extensive use and cleaning.
• Stout 4mm Construction — The thick aluminium construction delivers extra stiffness compared to composite shock towers, which eliminates flex and delivers flex-free control during high-speed cornering, big-air jumps and aggressive off-road driving. This rigidity is essential for precision handling and maintaining suspension performance under extreme driving loads.
• Greater Thread Engagement — The thick aluminium provides superior thread engagement for all hardware connections, making this tower extra tough for big-air action and hard impacts, with fasteners staying securely in place through the most demanding driving sessions.
• Perfect Factory Fit — As a genuine Traxxas part designed specifically for the Sledge, this shock tower requires no modifications or adjustments; it drops in perfectly and integrates seamlessly with your truck's suspension system and body mounting hardware.
• Compatible with Premium Suspension Upgrades — This shock tower is engineered to work perfectly with Traxxas' full range of Sledge suspension upgrades, including GTR hard-anodized shocks, TUBES adjustable links and heavy-duty components, allowing you to build a completely upgraded, competition-grade suspension system.

Technical Performance

This rear shock tower represents a significant engineering upgrade over the Sledge's standard composite part. The 7075-T6 aluminium material is approximately 30% stronger than the more common 6061-T6 aluminium alloy, providing exceptional strength-to-weight ratio that high-performance RC vehicles demand. By milling this component from solid billet rather than casting or moulding it, Traxxas ensures uniform material density throughout, eliminating weak points and voids that compromise durability. The stout 4mm wall thickness creates a rigid structure that resists the flexing and deformation that can occur under the extreme forces generated during high-speed cornering, big-air jumping and hard-impact landings typical of aggressive Sledge driving. The dark titanium anodised finish is not merely cosmetic; the hard anodising process creates a ceramic-like surface layer that's significantly harder than the base aluminium, providing corrosion resistance and abrasion protection that extends the component's lifespan dramatically. This shock tower integrates perfectly with Traxxas' other premium Sledge suspension components including the GTR shocks with 13mm bores that deliver 70% more oil capacity than standard shocks, and TUBES aluminium links made from 7075-T6 material with steel threaded inserts and heavy-duty rod ends. The combination of upgraded shock towers, premium shocks and adjustable aluminium links creates a suspension system with extraordinary rigidity, precision and adjustability. Whether you're running the Sledge on high-traction terrain or loose off-road surfaces, this shock tower ensures your suspension geometry remains consistent and your truck maintains predictable, responsive handling throughout the most demanding driving sessions.

Frequently Asked Questions

• Will this shock tower fit my Traxxas Sledge? — Yes, this rear shock tower is engineered specifically for the Traxxas Sledge 1/8 scale brushless electric monster truck and fits all standard Sledge models without any modification required. As a genuine Traxxas part designed by the same engineers who created the Sledge, it guarantees perfect factory fit and compatibility with all Sledge suspension components.
• What is 7075-T6 aluminium and why is it better than other alloys? — 7075-T6 is one of the strongest and most expensive aluminium alloys available, offering significantly superior strength compared to more common 6061-T6 aluminium. The "7075" designation refers to the specific alloy composition with zinc as the primary alloying element, while the "T6" suffix indicates the heat treatment process that maximises hardness and strength. This material is used in high-performance aerospace and competition applications where strength and reliability are non-negotiable, making it ideal for demanding RC racing and bashing.
• How much stronger is an aluminium shock tower compared to the standard composite part? — Aluminium shock towers are significantly stiffer and more rigid than composite parts, eliminating the flex that can occur under high-impact loads and cornering forces. This rigidity maintains more consistent suspension geometry, improves handling precision and ensures your truck performs more predictably. Additionally, the thick 4mm aluminium construction provides greater thread engagement for fasteners, making the tower much more durable for big-air jumping and hard-impact landings.
• Is this part suitable for beginner RC drivers? — While this is a high-quality upgrade component that benefits drivers of all skill levels, it is typically installed by enthusiasts upgrading their Sledge for enhanced performance and durability rather than beginning with a complete RTR kit. However, if you already own a Sledge and are looking to improve suspension performance and durability, this is an excellent upgrade that will enhance your driving experience regardless of skill level.
• What colour options are available? — This particular model features a dark titanium anodised finish for a sophisticated appearance. Traxxas also offers a blue-anodised version if you prefer a different aesthetic. Both finishes provide the same exceptional durability and performance characteristics.
• How does this shock tower improve my Sledge's performance? — By replacing the composite shock tower with this rigid aluminium component, you eliminate flex in the suspension mounting structure, which allows shocks to operate more consistently and precisely. This improves bump absorption, jump landing stability and cornering control. The increased rigidity also helps maintain suspension geometry under extreme driving loads, resulting in more predictable handling and better performance across all driving conditions.
• Can I upgrade just the rear shock tower, or do I need to upgrade both front and rear? — You can upgrade rear, front or both shock towers depending on your preference and budget. Many enthusiasts upgrade one at a time, though upgrading both creates the most significant improvement in overall suspension performance and handling consistency. Check RC Model Shop's current stock for the matching front shock tower if desired.
• How does this compare to other Sledge suspension upgrades? — This shock tower is part of Traxxas' comprehensive aluminium upgrade range for the Sledge, which also includes caster blocks, steering blocks, rear carriers and TUBES adjustable links.
