Will the TF243B fit other TF variants?

How much stronger is the reinforced arm?

The reinforcement ups the arm thickness from 3mm to 4.5mm, which improves resistance to breakage under heavy impacts compared with the stock part.

Is installation straightforward?

Yes, the TF243B keeps the same hole pattern as the TF243 so it is a direct swap with no chassis or suspension modifications required.
