These lowering blocks could be used to simulate a multi leaf to a mono leaf. The 2.5” width is correct and likely a 1” may make up the difference but checking on your part would still be preferred. They come in ½” increments and we even offer a ¼” if needed for your application.

These blocks are very universal and can be used on many applications. They measure 2-1/2" wide and 5" long with a 9/16" centering pin. Compare this to the springs on your car to be sure they will fit.

Can one of these blocks be used to raise the body in the rear of a 1931 Model A coupe about 2 to 2 1/2 inches? We are in the process of correcting a botched install of a Camaro rear end using the mounts for a 32 spring kit from speedway that, because it was mounted incorrectly resulted in gross shackle bind and lowering the body too much to have the original leaf spring functional. I want to try and salvage as much as I can without having to shorten the wheelbase to put the spring directly over the rear end housing rather than the 3 to 4 inches ahead like it is now.

These blocks are 2-1/2" wide and 5" long. They typically work well to lower the ride height of a stock Camaro suspension. Take some measurements of the size of blocks needed for your installation to determine if these are the correct size. If your spring is mounted below the axle tube these will lower the vehicle. If your spring is mounted above the axle tube then these will raise the vehicle.

These lowering blocks are 2-1/2" wide, 5" long, and have a 9/16" centering pin. I offer 1/2" U bolts that are for 3" diameter axle tubes that are 8" long 91043801 or 10" long 91043800. Compare these specs to the requirements for your vehicle to determine proper fit.

Blocks shouldn't be stacked on a street car.you can develop a situation from rough roads where the ubolts loosen and blocks get dislodged leaving you with a sudden ride height change or worse.My opinion is a helper leaf or a raised shackle with a single spacer would be better.

It is possible to stack these blocks but we recommend using one block of the proper height if at all possible for safety concerns.
