My dad has a Syverson Hack body on a touring frame...35 years of too much weight on too little spring (8 leaves) has taken it's toll and there's nothing left of the rear spring.

My quandry is whether to replace with a 9 or 10 leaf spring and was wondering what others with the same/similar body did with regards to the leaf count/spring rate

thanks in advance for your comments

I had the same problem with my 1921 Delivery. I added one additional main leaf (number two) above the bottom leaf for a total of nine and it cured the problem.

Sedans and pickups used a 9 leaf rear spring. I don't believe Ford made a 10 leaf.

Scott,

Like Larry, I don't believe there ever was a 10 leaf spring as part of a factory offering, but the vendors make them up today.

Whoever built my Hack in '09 (click profile)thought they would get by with a new 8 leaf rear spring...NOT...rides like someone welded the leaves together. (and there is nothing like the joy of needing to go down the concrete highway at 35 with the expansion slots and feel your teeth chatter with every one!)

I know I need to change it one of these days, and I sort of get it that 10 might be better since the Hack bodies generally go more in weight than a Fordor and I've been tempted to go 10, but it raises a lot of other questions for me, so I'll share the questions with you...and maybe get answers from the post too.

Is the standard center bolt long enough for 10?

Is the rear spring hanger long enough for 10?

Is the spring clamp the right length to capture 10?

I'd also question the length of each leave in the 10 set. If they are just piled up at the top with itty-biddy ones, I can't see the contribution...
