Traxxas Brass Steering Blocks Left Right 7g Each TRX9737

Overview

The Traxxas Steering Blocks (TRX9737) are precision-engineered components designed specifically for the TRX-4M 1/18 scale RC crawler. These brass steering blocks represent a sophisticated weight distribution upgrade that transforms how your RC trail truck performs on challenging terrain. Whether you're navigating rocky outcrops, climbing steep grades, or crawling through technical obstacles, these steering blocks deliver the mechanical advantage serious RC enthusiasts demand. As an authorised Traxxas retailer in the UK, we recognise that RC car upgrades like these are essential for maximising performance and durability in your RC crawler.

What makes these steering blocks particularly valuable is their strategic placement and material composition. By adding 7 grams of weight to each steering block (14 grams total), you're placing this mass at the lowest possible point of your TRX-4M, directly over the front axles. This geometric advantage significantly improves anti-rollover stability and enhances your truck's ability to maintain grip on steep climbs. The brass construction provides superior durability compared to plastic alternatives whilst maintaining the precise geometry that Traxxas engineers have tuned into the TRX-4M platform. For UK RC enthusiasts who demand trail-tested performance, these steering blocks represent a worthwhile investment in your machine's capability.

Installation is straightforward, and the package includes all necessary hardware with threadlock applied for security. If you're serious about pushing your TRX-4M to its limits on challenging terrain, these steering blocks are a proven upgrade path recommended by Traxxas themselves as part of their comprehensive TRX-4 upgrade ecosystem.

Key Features

• Brass Construction with 7-Gram Weight Addition — Each steering block weighs 7 grams, delivering a total of 14 grams of additional weight positioned at the lowest point of your truck's chassis, directly over the front axles for dramatically improved climbing and crawling performance on steep grades.
• Optimised Weight Distribution for Anti-Rollover Stability — By placing weight at the lowest possible point rather than raising the truck's centre of gravity, these steering blocks enhance lateral stability when traversing rocky terrain and navigating challenging obstacles without compromising handling characteristics.
• Precision Machining for Geometry Preservation — These steering blocks are carefully machined to preserve the TRX-4M's trail-tuned steering and suspension geometry, ensuring that this upgrade enhances performance without introducing unwanted steering quirks or handling changes.
• Complete Hardware Package with Threadlock — The upgrade includes two 2.5x12mm ball cap screws with threadlock and four 2x6mm stainless steel screws with threadlock, ensuring secure fastening that won't loosen during aggressive trail driving.
• Stainless Steel Hardware for Corrosion Resistance — The included stainless steel fasteners provide superior corrosion resistance compared to standard hardware, essential for UK climate conditions where moisture exposure is frequent during off-road adventures.
• Left and Right Configuration — This package includes matched left and right steering blocks, providing symmetrical weight distribution and balanced handling characteristics across both front corners of your TRX-4M.

Technical Performance

The Traxxas Steering Blocks TRX9737 represent a carefully engineered performance upgrade backed by Traxxas's extensive experience in RC crawler development. Constructed from brass, a material chosen for its superior durability and weight characteristics compared to aluminium or plastic alternatives, these steering blocks deliver tangible performance improvements on technical terrain. The 7-gram weight per block (14 grams total) is positioned at the absolute lowest point of the chassis, directly over the front axle, creating a mathematical advantage in climbing capability and anti-rollover stability. This weight placement works in harmony with the TRX-4M's renowned suspension geometry rather than fighting against it. The precision machining ensures that every dimension matches the OEM specifications perfectly, so installation results in improved performance without any steering binding or geometry issues. The included hardware—2.5x12mm ball cap screws and 2x6mm stainless steel screws, all pre-treated with threadlock—ensures that your upgrade stays secure through demanding trail sessions. Whether you're exploring rocky creek beds, climbing near-vertical obstacles, or navigating technical trail courses, these steering blocks provide the mechanical foundation for peak TRX-4M performance. UK RC enthusiasts will particularly appreciate the stainless steel hardware, which resists the corrosion that can plague brass and steel fasteners in the damp British climate.

Frequently Asked Questions

• Will these steering blocks improve my TRX-4M's climbing ability on steep terrain? — Yes, significantly. By adding 7 grams of brass weight to each steering block at the lowest point of your chassis, directly over the front axles, you improve weight bias and create superior grip on steep grades. This weight placement enhances your truck's ability to maintain traction and climb obstacles that would challenge a stock truck.
• Do these steering blocks alter the TRX-4M's handling or steering geometry? — No. Traxxas engineers specifically machined these steering blocks to preserve the TRX-4M's trail-tuned steering and suspension geometry. The upgrade improves performance without introducing unwanted handling changes or steering quirks.
• Are the included screws sufficient for installation? — Yes, the package includes all necessary hardware: two 2.5x12mm ball cap screws and four 2x6mm stainless steel screws. All fasteners are pre-treated with threadlock to ensure they remain secure during aggressive trail driving.
• Why brass instead of aluminium? — Brass offers superior durability and weight characteristics compared to aluminium or plastic. The material's density delivers more effective weight bias improvement whilst resisting the wear and impact damage that occurs during serious trail driving.
• Are these suitable for beginners exploring RC crawling? — These steering blocks are an intermediate-to-advanced upgrade designed for drivers who want to maximise their TRX-4M's off-road capability. They're particularly valuable if you regularly tackle challenging terrain, but they're not essential for casual trail driving. Beginners will benefit from learning basic RC car handling before adding performance upgrades.
• Will I need any tools beyond the standard RC toolkit to install these? — Installation requires basic RC tools: a hex wrench set that fits the 2.5mm and 2mm screw heads. No specialised equipment is needed, making this an accessible upgrade for most RC enthusiasts in the UK.
• How do these steering blocks compare to the optional aluminium steering blocks? — These brass blocks (TRX9737) provide maximum weight advantage for climbing and crawling performance, whilst aluminium alternatives prioritise lighter weight and reduced rotational mass. Choose brass if climbing and anti-rollover stability are your primary concerns; choose aluminium if you prefer a lighter-weight approach to steering response.
