Tamiya 53990 - TA05 Aluminum Bulkhead Chassis Reinforcement Upgrade  [53990]

Stiffen and Tune Your TA05 Chassis

The Tamiya 53990 - TA05 Aluminum Bulkhead is a practical upgrade for hobbyists who want to increase chassis stiffness and expand suspension adjustment options. Machined aluminum construction strengthens mounting points and provides several upper arm pick-up positions for more precise setup changes.

Improved Rigidity with Multiple Upper Arm Mounts

This bulkhead is engineered to reduce flex in both front and rear sections, giving a firmer platform for sharper cornering and consistent handling. The extra upper arm positions let you change roll center and camber response to match different track surfaces or driving styles.

Fitment Notes for TA05 Chassis

Made to fit the TA05 platform, this bulkhead installs into standard TA05 layouts without modification. Be aware that TA05 IFS variants with their unique front suspension cannot accept this part at the front.
