RPM have produced these shock towers for the SC10 & T4 that are designed to improve the structure and durability of these awesome racing trucks. The I-beam shape found along the tops and sides of tower provide some serious strength and rigidity while the chemical make up of their proprietary blend of nylons provides unmatched durability. The end result is a new shock tower design that will rigidly support the rear shocks while allowing the part to survive under extreme crash situations. Additionally, the unique nature of the materials help reduce transferred impact energy into the fragile chassis and chassis components. By absorbing that impact energy instead of transferring it on, this shock tower will improve overall crash survivability of the truck. All this and not one gram is added to the weight of the vehicle.
