Just recieved and installed my Quad Race Box
this afternoon. My truck is an 04' 305-555,48RE,4x4,{I know I got to update my sig}. Been running an EZ set to level 5 for a little over a year now and its worked great. But you know how it goes,wanted adjustability and more power on the top end. Let me tell you this THEE Box Oo. cant beat it for power,price,and ease of install! Idle is nice and smooth and power comes on smooth as well! Got to go for another ride right now
,maybe if it doesnt rain tommorow I can try towing with it.
