Tamiya TT01/TT01E Rear Lower Arm Upgrade for Chassis Balance - JR-TT107-BK by Jazrider  [JR-TT107-BK]

Rear Arm Upgrade Details

This rear lower suspension arm kit fits the Tamiya TT01 and TT01E platforms, supplied in black and identified as model JR-TT107-BK. The set replaces factory plastic rear lower arms with machined aluminum parts designed to locate on the original rear suspension mounting points.

Use these arms when you need improved repeatability in rear-end behaviour during track or setup work. The upgraded arms influence pivot geometry and wheelbase alignment, so they are typically matched with shock and toe changes to fine tune handling. They are intended solely for RC applications.

Installation notes: remove the stock rear lower arms and mount the aluminum replacements to the same points, reusing chassis screws and pins where suitable. Typical installation only requires basic hand tools and a hex driver; after installation verify pivot free play and that linkages move without binding.
