shock absorber substitutions-37 sedan

Go to solution Solved by Frosty,

Recommended Posts

I recently purchased a 37 silver streak sedan deluxe 8.  I am in the process of rebuilding the brake cylinders, pads, hoses etc.  My next focus is on the suspension.  Does anyone know if I can replace the REAR shocks with a readily available modern shock?  The rear shocks look very similar to todays shocks but maybe they  cannot be upgraded.  Any advice would be appreciated.   Thanks!

I see no reason why you cannot use a modern shock on a car that old. You simply need to measure the length you need for your ride.

How to Measure Shocks

A shock is measured by its extended and collapsed lengths, and is measured from the center of the loop mount or the base of the stud mount. To get the extended length of a shock, remove it from the vehicle and allow it to expand on its own or pull it to the fully extended position and take a measurement. To get the collapsed length of a shock, compress it by hand or by using a strap and take a measurement. With the expanded and collapsed lengths of your current shocks, you will be able to find a suitable shock for your custom application.

Thanks for the reply Frosty.  I'll remove the shocks, measure as you suggested, and head to NAPA!
