Exotek Racing have introduced new option parts in the form of front shock tower for all TLR 22T series stadium trucks and aluminium rear differential cups for the TLR 22-4 2.0. First up is the front shock tower. Machined from 4mm carbon fibre, this lightweight (only 12gr) shock tower features a heavy duty construction with a factory look and a more robust material than the stock plastic for consistent handling on high grip tracks. It is designed with reinforced profiles along the mounting holes for added strength and includes hardware to mount the stock body posts.

Next up are the ultra light 7075 hard anodized aluminum rear differential cups. Designed to be use with MIP Puck bones, they only weighs 2.8gr for both versus the 7.2gr for both stock steel cups. They convert the rear diff to accept super light weight MIP B64 rear 65mm Puck bone set #MIP17042 or use Exotek 66mm Puck bones #1793 (note 67mm puck bones runs too deep into the cups). The rear differential cups are made for use only with stock spec 13.5 and 17.5 racing.
