I have a 52 F1 that I have been working on for 5 years and have finally gotten on the road. It has a 302 with a 4speed tranny. The front suspension is all stock with posie super slide springs. I bought new shocks that were original replacements but when I hit a bump, the front end sounds like it's falling out from under the truck. It seems like my rebound travel may be too short. Anybody running a similar set up?any recommendations on shocks?

 

I asume that you put Posie's Dual-Flex in the front? I have the same setup and Posie's recommended a lower profile stop bumper which I got from them. I'm not sure how your 302 is mounted but with a flathead V8 you have to make sure that your motor mounts are not collapsed or you could hit the oil pan. I also used Bilstein gas shocks per their recommendation. Suggest that you talk to them. They were very helpful.

Depending upon how low your engine sits you may have to install some air bags between the spring/axle mount and the frame. You can then adjust the air to control how much jounce you get.
