Model T Ford Forum: Forum 2014: Hassler shock spring sizes??
Top of pagePrevious messageNext messageBottom of page Link to this message  By David Schwab on Sunday, October 12, 2014 - 08:06 pm:

I got what I thought was most of the parts for a set of single spring Hassler shocks at Hershey. The price was good so I thought I might be able to come up with a couple of the missing pieces. The 3 springs that were in the parts were all crammed inside each other, so I didn't notice this until I got home and got them untangled. I have one spring 4 3/4" at the base and 6" tall, one 4" X 6" and one 4" X 7", which has a #42 stamped in it. What would be the correct size springs I need for the single spring shocks. Looks like the 4 3/4 are the right diameter. Are they supposed to be 6" or 7", or different heights for front and rear? The other thing missing is the arm on one of the rear ones, I have the plate that bolts to the axle, just don't have the arm that attaches to it. Is there a left and a right, of they interchangeable?

There are three different size Hassler Springs.

1. Normal size for the lighter open cars

2. Springs for heavier cars like Center Doors, Sedans and Coupes. These are DOUBLE SPRINGS, higher and smaller openings on top.

3. Springs for TT trucks. Much heavier spring (thicker) and I believe larger at the base.

You can get a reprint of the Hassler Spring instructions and parts lists from Lang's. Very helpful

These two may help you. There is one rear lever, no left or right. The front levers are left and right.

Forgot to add:

That #42 spring is for the Twin Hasslers, used on the closed cars.

Thanks Dan, that helps, but may add one more problem. The part that attaches to the rear axle, "4 left" and "4 right", I have 2 of that part... how do I tell the left from the right?

The "flat" that holds the lube bolt in position faces towards the rear to ease in the access for lubrication.

Best to get the reprints of the install instructions and price lists from Lang's.

Will save you time and the spring install is dangerous if you don't follow the instructions and make or borrow the spring tool that must be used.

Note "A" is the grease cup end of the bolt resting in the 'notch' of the rear bracket, each L and R have the notch on the opposite ends, so that is what makes a left and right #4. And "C" is the special tool you can make your self, it is needed!




The #4 can be identified by the 'notch' or flat area around the Hassler lubrication bolt, that bolt has two flats that keeps it from turning. The lube bolt with its grease cup faces toward the rear of the car for maintenance ease.


When identifying the Hassler parts, use the Price List book as it has illustrations in good detail. And remember that when you see the casting marks "RH" that does not mean Right Hand, it means "Robert Hassler" the company name :-)

Many years ago,I helped Ted Ashman on some Hassler history.He told me the springs were identified (for weight load) by a dab of colored paint on the end of the spring.Sadly most of that is eroded away,so the individual differences are hard to detect.

I use a digital caliper to measure the O.D. of the springs - they are different diameters for different weights.

Steve, do you have some reference to the diameter vs the part numbers listed above?
I have 4 sets of springs with diameters of .316,.382,.406, .411 do these match any diameters you have come up with?

No Dean, I do not have any documentation regarding the spring diameters. I measure both diameter & height to ensure I have matching springs prior to assembly.
