lowering blocks
Is it okay to use lowering blocks to adjust your ride height on the back of a leaf spring car, that will be used for drag racing? I have seen alot of 9 second cars that do run them. Other racers say not to. I know there are alot of fast cars on here with leaf springs. Does anyone use them?

I'd like to know about this as well.

Re: lowering blocks
I've got some 1" solid aluminum ones on mine. Haven't had any issues with them yet.

I have them on my car now and I've had them on the last two cars. I can sell you a set ready to install if you want them.

Re: lowering blocks
It hard to lower a leaf spring car. Shortening the shakles or flatening out the leaf spring just doesn't get the ride hight you want. I started using blocks about 10 yrs. ago and have had no problems with them. I us only solid blocks and I haven't used anything thicker than an inch.
I cut them and get them ready for use. If you would like a set just let me know. $45.00 to your door.
I'll post some pics tomarrow.

Re: lowering blocks
Do you have a good source for the "u" bolts?

Re: lowering blocks

Re: lowering blocks
Seeing those pics make me wish I went with a longer rear end and more backspace on my rims. My calipers will have to be moved before I lower it or they'll be too close to the frame rails.

I run a fast leaf spring car, I dont run lowering blocks (I like my car tall), but as long as you have a good anti-twist bar setup there is no reason you cant run lowering blocks.
