2wd rear blazer coils HELP
Hey guys I got a new project 70 blazer I lowered it with rear coils 4" CPP these were crap bottomed out on everything and bounced up and down. I switched to a 3" Western chassis these are WAY better support the blazer alot better no bouncing and squishiness, But with my two teen kids in it the blazer bottoms out. I know its the extra weight but I was wondering if there was something I could do to keep it low and still support the weight? Something other then bags? Thanks for any help

Re: 2wd rear blazer coils HELP
Did you trim the bump stops after you lowered it ?I know you don't want bags but they do make a helper one that goes inside the coil spring.

Re: 2wd rear blazer coils HELP
Yea but coils support the weight and shocks just keep it from bouncing as much.So I'm not sure a stiff shock would make all that much difference?

Re: 2wd rear blazer coils HELP
talk to people who know what an air shock is and people that have used them // they ARE NOT regular shocks that you have mistaken them for

Re: 2wd rear blazer coils HELP
Yea I've had several cars with air shocks I'm familiar with how they work. They still work like a shock just one you can adjust the firmness on. So yea I guess I could buy them over fill them so theres no give and run them like that. But I was curious if anyone else had a similar issue with a blazer and what kind of coils there running in the back.

Re: 2wd rear blazer coils HELP
I ran 6" drop coils from ECE on my 2wd blazer when it was static dropped.
It did bottom out with a truck load of people in it. Removing the top helped a little, since the back raised up about 1". I didn't find the answer until I bagged it. I installed a bolt-in c-notch. That cured the problem.

Re: 2wd rear blazer coils HELP
I have a 71 chevy LWB with 4" drop coils. I put the helper bags inside the coils and it made a world of differance. I can load it up now and never bottom out. I have no c-notch either and can't see cutting the frame as so many do.
I ran my air lines to the back bumper and installed the shreader valves as my tag bolts.

Re: 2wd rear blazer coils HELP
Hey Andy - - where did you get your helper bags from? Was this cost effective compared to just using air bags on the rear?
