Overview
The RPM Castor Blocks for Traxxas Electric Stampede, Rustler, Slash and Bandit represent the pinnacle of front suspension engineering for your 2WD RC car. Whether you're a weekend basher enjoying your ready to run RC truck or a serious competitor looking to upgrade from stock components, these caster blocks are the final piece of the puzzle for a bulletproof front suspension setup. RPM has redesigned these critical suspension components to eliminate unnecessary bulk whilst simultaneously improving strength and durability in this heavily impacted area of your vehicle. If you're running a Traxxas Slash 2WD, Nitro Slash, electric Rustler, or electric Stampede 2WD, these replacement caster blocks will transform your front end performance and longevity.
As a stock replacement item, these caster blocks require no additional parts or modifications to install on your vehicle, making them an ideal upgrade for anyone looking to improve their RC car's suspension without complex modifications. The RPM caster blocks are moulded in RPM's trademark blend of ultra-durable and super-strong nylons, engineered to withstand the punishment of aggressive driving, high-speed impacts and challenging terrain. Every set is backed by RPM's industry-leading breakage warranty, giving you complete peace of mind that your investment is protected. For anyone serious about RC cars in the UK, these caster blocks represent genuine value and uncompromising quality.
These components sit at the very foundation of your truck's handling characteristics and durability. The caster blocks connect your suspension arms to your steering linkage and are subject to enormous forces every time your vehicle hits a jump, lands from a bash, or takes a corner at speed. Using quality aftermarket caster blocks like these RPM units means you're investing in longer intervals between repairs, more consistent handling, and ultimately a better driving experience whether you're running on grass, dirt, tarmac or asphalt.

Technical Performance
The RPM Castor Blocks represent a significant engineering achievement in suspension design for 2WD RC cars. These components are moulded from RPM's exclusive nylon composite material, which combines ultra-durability with exceptional strength to create a part that can withstand the severe stresses placed on caster blocks during normal driving and aggressive bashing. The caster angle of 30 degrees is retained from the stock Traxxas specification, meaning your vehicle will maintain its original suspension geometry and handling characteristics whilst benefiting from dramatically improved durability and component longevity. The redesigned profile reduces unnecessary material bulk without compromising structural integrity, resulting in a lighter component that doesn't sacrifice strength—a crucial balance in suspension design. Installation is straightforward as a direct replacement for Traxxas stock number 3632, requiring no additional brackets, modifications or suspension tuning. The engineering quality is evident in every detail, and the comprehensive warranty coverage demonstrates RPM's confidence in these components. For owners of Traxxas Slash 2WD, Nitro Slash, electric Rustler and electric Stampede 2WD models, these caster blocks represent the logical upgrade path for anyone serious about improving their vehicle's suspension durability and reliability.
