    I had a post going about installing timbrens on a 4" lifted GMC 1500 and if anyone has done this before or if anyone had any pointers. For some reason I can not find the post now. Anyway I have them installed we machined a 4" extension that bolts straight to the bracket that comes with the timbren spring then drilled out the threads on the rubber spring and put a 7/16 bolt through the bottom of the spring up into the machined extension. (I think the warranty is probably no good anymore HAHA) anyway it is a very clean install. The rubber springs do rest on the A-arm with all the weight off of the front end. This didn't effect the ride in anyway and I had the truck realigned and everything aligned perfect. My question is how much sag should I be getting? When I put the plow on (7'6" Boss V) I am still getting a lot of sag. I don't have any weight in the truck bed. Would this really help much? I have not had a chance to measure how much drop I am actually getting but I will try to do that. I also do not know how much sag I got with out the timbrens but just looking at it and comparing to what I remember from last year it sure seem like the timbrens are not doing much. Any ideas or input would be great since this morning there was a hint of the white stuff on the ground.

    remember your using a 1500 which is a lighter truck. you will get a lot of sag. i remember this when i was using a 1500 dodge ram. when i switched to a ford f 250 i could see and feel the difference in the front end with a heavier truck just my 2 cents
