Heidts 1970-1981 Camaro/Firebird front Pro-G bolt on subframe is all new and offers fitment up to a 335 tire, and LT, LS, small block and big block motors. An excellent and easy way to update your 1970-1971 F-body. You will get a new bolt-in subframe, adjustable upper control arms and 1-1/2″ lower control arms, our Pro-G drop spindles, adjustable billet coil-over shocks w/springs, power rack & pinion, universal trans crossmember, and 11″ Wilwood disc brakes with 4-piston calipers. This is one of the best bang for the buck subframe kits. If you are looking to update the handling of your 67-69 F-body but don’t want to break the bank, this is the kit for you. Want to take it to the next level ? Upgrade the bushing rod ends on the upper arms to heim joint rod ends to tighten up the steering & suspension followed by a brake upgrade to 12″-13″ Wilwoods with drilled and slotted rotors and add the 1-1/4″ solid splined swaybar and you are ready for some serious fun.
