Frequently Asked Questions

• Which RC crawlers and axle systems is this U-bolt kit compatible with? — The RC4WD Z-S2128 U-bolt kit is specifically designed to fit the Yota II Ultimate Scale Cast Axle system. This includes both the front axle (Z-A0080) and rear axle (Z-A0081). It will not fit other axle systems, so verify your current setup before purchasing to ensure compatibility with your RC 4x4 crawler.
• Is this kit suitable for beginners building their first RC crawler? — Whilst the hardware itself is straightforward to install, this kit is designed specifically for the Yota II axle system and requires those axles as a foundation. If you're building your first RC crawler in the UK, you'll need to purchase the compatible Yota II axles separately, making this a component for builders with some RC experience rather than absolute beginners.
• What materials are used in this U-bolt kit? — The kit combines hardened steel U-bolts with 6061 aluminium alloy plates finished in black anodising. This combination provides the strength and durability needed for serious off-road RC use, whilst the black finish offers modern aesthetics and corrosion protection suitable for outdoor RC activities in UK conditions.
• How much weight does this U-bolt kit add to my RC crawler? — The complete kit weighs just 1.05oz (29.9g), making it virtually negligible in terms of weight addition to your RC vehicle. This minimal weight penalty means you'll enjoy the authenticity and structural benefits of proper scale suspension hardware without compromising battery runtime or handling characteristics.
• Why would I need this U-bolt kit for my RC Yota II crawler? — This hardware kit provides two important benefits: firstly, it adds authentic scale detail to your RC model, replicating the real U-bolt suspension systems found on full-size 4x4 vehicles, and secondly, it provides functional structural integrity to the axle assembly, distributing loads effectively across the suspension system for reliable performance in demanding off-road RC driving conditions.
