I've got a '29 Model A 4 door Town Sedan that I want to lower the rear 3-4 inches. I'm running the original rear spring (10 leaves stock) and already removed 3 leaves. It dropped probably 1/4-1/2in if that bit it is a little softer. I need to close up a 4 in fender to wheel gap. I'm running the '35 16in wires with 7.50 in the rear and 5.50-6.00 tires up front. I have a Super Bell 4in dropped axle in the front and I am running a '51 Flathead with the '39 three spd to a stock Model A rear end. I guess my question is I need to remove as many leaves from the rear but want to stop it from bottoming out too. Any help/suggestions/thoughts???
I hear a Model T rear spring will help lower it. Not sure how much, but that's what I plan on doing on my 29.
Millworks sells a reverse eye main leaf. That should help get you lower. https://www.millworkshotrod.com/col...-rear-reversed-eye-main-leaf-spring-1928-1931
I took at least 4 leaves out of my reversed eye main leaf from Vern Tarbell. It was one too many. It will bottom out when hitting a dip in the road at low speed. The best next step is likely a reversed eye spring. It is a trial and error process for almost every car. The Briggs and Murray sedans are heavier than most A body styles. Be safe, they are a bear to remove and install.
Model T spring with the shortest A spring on top to fit the cross member. 6 leaves total. Stock eyes. sits it right there. Had 750-16’s on 35 wires on it before. Sits the same obviously as these 750/16 on steelies.
It's always a bit of work to get it just right. I like using a V-8 closed drive axle with the A spring behind the bells and building a spring perch off the rear crossmember. The spring perch is doable through the floor pan and is hidden under the back seat cushion. Just a different way to skin the Dog.
I heated the bottom 2 leafs with a torch to put a kink in them. Seems to have been common in the circle track cars.
