These shock towers are designed to take some serious abuse without failing because nothing is worse than having a part break when you're out having a fun day, whether it's at the local track or at your favorite place to bash. Structurally, RPM shock towers for the Slash 4x4 & Telluride are about as strong as they can be, keeping your suspension moving freely without added flex. However, under extreme crash situations, the nature of RPM's proprietary materials allows it to give slightly, absorbing that impact energy to prevent damage to the shock tower and reduce the amount of transferred shock energy to the more fragile differential cases. This material then returns back to its original shape almost instantly. No other material can do that! Additionally, RPM shock towers retain the large dust cover ribs that overlap the tops of the differential case, providing an extra layer of protection against dirt and grit not found on many aftermarket shock towers.
