Can anyone tell me the dimensions & brand of your high steer arms. I've been running a 5.0 in my '85 Xtra cab (with 4 1/2" springs & 2" body lift) for years now & have put off high steer for fear of the oil pump being in the way. Trail gear techs give me the run a round & say i'm over complicating this but I know damn well what room I have & i'm not going to piss away $300 just because he said it SHOULD fit. I need to know the gap between the tie rod & the spring & the center distance between the tie rod end & the front stud. Trail gear said the tie rod hole is the same distance from the axle as stock, just elevated. My stock hole is 6" centered from the front stud. I just measured a friends truck with high arms that had 4 1/8" centered spacing. These arms would give me plenty of clearance but he bought the truck third owner with the arms already installed & we don't know what brand they are. I'm more than aware that the axle will move rearward when the spring flexes but not near as much as the drag link pivoting forward when the pitman moves side to side. This forward movement is whats causing contact with with my oil pump. Height of the drag link when flexing with the wheels straight it will bearly clear but turn the wheels & it makes full contact. If it would clear the pump I can modify the pan to fit.
