HTD Rear Subframe
This is a custom designed unit to replace the factory subframe which allows for easy V-8 installations with our Eliminator kit. It comes with tubular lower contol arms to be used w/stock rear ball joints. The bumpsteer associated with the original design has been eliminated with this subframe. The V-8 engine is supported in the regular manner with no other extra support required. You can use the factory rubber mounts to eliminate all vibration coming from the power train, or the option to use urethane is available.
