This is an Exotek Short Traxxas Slash Carbon Front Tower, a low profile, low ride height, heavy duty 3.5MM thick carbon fiber front shock tower for 2wd Slash street eliminator cars. A lower tower set-up allows you to mount the body to the lower levels desired with drag racing by using the Traxxas body post set (TRA1914R). Use the Traxxas 4tec shocks (requires TRA8360) to lower the front ride height. NOTE: Optional- You can use the stock Slash front shock by removing the springs as shown. This will lower the car and keep the nose from bottoming out at high speed but also allows front wheel droop for controlling wheelies (use 20wt oil).
