This is the Revolution Design Racing Products 4mm Ultra Turnbuckle Wrench. This turnbuckle wrench is a handy multi-purpose tool that combines a 4mm turnbuckle wrench with a 5.5mm nut driver. Used on 1/10 scale vehicles the tool lets you adjust many important setup parameters such as camber, front suspension toe and even the shock angle. The 5.5mm nut driver also lets you adjust the slipper setting of 2WD buggies and trucks with metric fasteners. The small size and versatility of the Ultra Turnbuckle Wrench helps you to make virtually last second setup changes while having your car in the starting grid. It is also great for general building and maintenance too.
CNC machined from 7075-T6 aluminum and black anodized the wrench perfectly matches the RDRP Ultra tool line with the laser-etched size markings always telling you what wrench you are using. The high strength steel cross pin acts as a grip to let you tight and undo nuts with authority in case you need to.
