TAMIYA TA05-IFS/TA05-R Track Motor Stiffener TA05-IF09/LB by 3Racing  [TA05-IF09/LB]

This aluminium motor stiffener is an RC accessory for TAMIYA TA05-IFS and TA05-R chassis, offered by 3Racing as model TA05-IF09/LB. It reinforces the motor mounting zone to cut down flex when the drivetrain is loaded.

Compatibility is restricted to the TA05-IFS and TA05-R formats stated, and the component is intended to replace or supplement the original motor mount on those Tamiya chassis. The aluminium design increases rigidity at the motor to gearbox junction.

Fitting advice: the stiffener mounts around the motor area and aligns with the existing chassis and motor mount points on TA05-IFS and TA05-R. Typical installation follows stock mounting locations and should not change drivetrain geometry, making it suitable for competitive track setups.

Tuning benefits: installing an aluminium motor stiffener reduces motor movement under throttle and braking, which helps preserve pinion-to-spur engagement and supports more consistent lap performance. It is most effective when used alongside suspension and gearbox setup work.
