Got sick of the bouncing, floating front end feel, in my 03 Blazer 4x4. So I took some measurements and adapted a new set of EMPI 00-9570-8 adjustable coil-over shocks that were made to fit the Rear of a "Baja Bug" Volkswagen Beetle. I had to tighten the mounting sleeves at both ends of the shocks into a vice and then drill out the sleeves to the 1/2" bolt size that are on the blazer (upper and lower). The EMPI coil-overs come with a sleeve that's 1/16th too small. Also had to use a bench grinder to shorten the length of the lower sleeves, and then shimmed the upper sleeves with galvanized 1/2 inch washers. After I installed them, I backed out of the garage to allow the ride height to settle and noticed that the front end was too high. I didn't wanna raise it any higher than I already had it to keep from damaging the CV joints and or blowing out a CV boot. So I had to back off the torsion bar keys a full turn and a half to get the height to where it was at before the install. The way I see it, these coil-overs are just helping out my torsion bars with carrying the weight. The torsion bars still do most of that job. As a result of this mod, my Blazer now rides exactly the way I'd hoped for. It rides very stable, without the floaty ride that came with the stock set up, and eliminated the need to install larger bump-stops to eliminate the blazers springy ride when the torsion was raised off the stock bump-stops.

I didn't change the spring setting on the new shocks from where they came out of the box, on the softest setting. There was no need to put more spring tension than the lowest setting.
If you're thinking about doing this to your Blazer, then I highly recommend that you DO NOT try to drill out the sleeves without a vice clamped on the sleeves while drilling, otherwise you'll spin the sleeve in the shock and destroy the rubber bushing that the sleeve is bonded inside of.
Good luck! Hope you guys like the ride improvement as much as I do.

The sleeves on the coil-overs came with a 7/16th's inside diameter. I drilled them out to accept

Hey I'm thinking about doing this to my blazer how'd it hold up over the years? Any issues?

The coil-over shocks are holding up great, I'm still running the same set and they're still one of the best things I've done to improve the ride and handling of my Blazer.

Looks good I think I'm going to do the same thing.

I just did it to my truck this weekend and it made a huge difference so far I'm very happy with the results.
