Thank you for viewing. This is the MB01 H-arm 32mm 0.6deg. Recently, various companies have released M-chassis conversions, but they are mainly focused on the front end, and there are limited options for the rear suspension. This product was created to address that. It is compatible with all M-chassis using suspension pins. Arm Length: 32mm *31.5mm at the shortest point Toe-in: 0.6deg Reverse Skid: 2.4deg Installation is possible by changing to suspension pin specifications. *Suspension pin conversion bushings are included. The intended use for the knuckles is the rear knuckles of TT01/TT02. Slight wheelbase adjustment is possible on the chassis side, so please adjust during installation. *46mm suspension pins, F630 bearings, and a set of installation knuckles are sold separately. A larger toe-in tends to provide stronger longitudinal traction, but please enjoy the setup to your liking. *If the bearing falls out due to product precision, please apply a small amount of rubber-based adhesive before inserting the bearing. *The ball joint insertion points have been threaded, but please be careful not to overtighten the screws. We strive for same-day shipping. Thank you very much. *This is a 3D printed product, so there may be some burrs. Please understand. *Excessive force may lead to deformation or damage. Please be aware. *Material: PETG-CF #TT01 #TT02 #Tamiya #SuspensionArm #Secret-Labo #Radidori Type...Radio Control Manufacturer...Tamiya Type...RC Parts Radio Control...RC Limited Parts
