I have never ran tg springs. My only expierence is with all pro or marlin. I have built two rigs now. I sold my first one to one of my closest friends. The all pro springs on that rig are going on 5 yrs now and have not flattened out and still flex like crazy. My two cents is that it was worth the extra coin I spent on the springs. I have only heard bad things about tg springs. Does any one have proof that they are chinese steel?
No noone does. They like to just talk smack because TG via good ole chris gieger the 4wd shop sleeper was going to merge with marlin and backed out at the last second. Anything they have to say about them is unfounded and generally they have never owned a tg part let alone held one in their hands. If they were as bad as they say they are on here my truck would have exploded or fell apart by now.
Allpro springs used to have a very bad issue where they would bend near the eyes making the spring into an S shape and sag very bad, If they still do this or not i am unsure.
