can you use lowering blocks to lower the rear of a c10 with the coil spring trailing arm suspension?
my 65 has 3" blocks ...and 77 monte carlo springs.....i made a new panhard bar to keep it square....not slammed ....but its a definently driveable.....thanks brandon forgot to mention .....the blocks are special to that truck .....not like a leaf spring setup .....
so regular blocks wont work?.... guess im clamping the springs
Not with the coil spring setup.
You can also purchase aftermarket springs that are shorter.
forgot ...some were leaf spring......and not trailing arms .....i would think that normal blocks would do........oops.....haha brandon
this one is trailing arm so regular block will or wont work?
If ya put blocks on you'll just move the arms away from the rear - to lower it you have to do something with the springs - either cut them or replace them with shorter ones.
Here is a picture and an article on the process.
....that makes no sence
For the trailing arm syle. You can make your own blocks out of square tube steel, they just have to be cut on a slight angle (to match the trailing arm) and get longer U-bolts. I thought about doing it for my 61 Apache10.
You can't cut these springs as they are tapered at the top & bottom. I priced out about a year ago drop springs for mine and they were around $120.
I've built a bunch of them in the past for these coil spring trucks.
Here's a set I built for my neighbor's truck. They are 2x3 thick wall tubing that I boxed the ends of. A local spring shop builds me the u-bolts for 30 a pair. You need them 2 inches longer than stock.
Beware though, these are 2 inch blocks and those are 17 inch wheels. Imagine what the scrub line would be like with taller blocks or smaller wheels. The 15 inch wheels that Brandon the poster above has coupled with his 3 inch blocks would hang way lower.
You can cut the coils on those trucks. I've done several but the spring won't have the small coil at the bottom. I usually take the springs out of the back and cut two loops off the bottom of the spring then bolt the top back up and bolt the cup on the bottom to the trailing arm like its suppose to be. Then let the truck back down. My last 3 64-66 chevy trucks have been done this way and they still ride alwright for me. sometimes you still have to make a new panard bar but other than that its pretty straight forward.
