SRT-4 Wastegate Actuator Kit

Ditch your stock 4psi wastegate actuator for a high pressure adjustable AGP billet aluminum unit. This replaces the factory installed piece, and will allow you to hold higher boost pressures to redline. No longer will your boost drop off to 11psi by 6000 RPM. We’ve been able to hold over 17psi, which seems to be the limit of the stock fuel system. Other benefits include reducing the amount of boost spike, as well as eliminating the oscillation that is common with light spring actuators. This kit includes a custom machined bracket to mount up to the factory points on the back of the compressor housing and is fully adjustable for preload.
