You have the ability to explore many different options with this project. I believe that the blazer has the same frame setup and rides on the same chassis as the S-10 or S-15. If it is the same chassis as the S-10 then you are in luck.
(1) one way to lift your truck, SUV is by adding 3 inch lift spindles. You can get high quality spindles from BullsEye. Fabtech sells these but you can get them at a better price from my friends down at Camburg Engineering. http://www.camburg.com
They have a great system for S-10 and Blazer trucks. You might end up spending 650 at the least because the only way to lift your truck up besides the spindles is:
(2) by changing upper A-arms and adding a shock and spring. Call Camburg at 1-714-848-8880 they can help you out a lot.
The spindle kit costs $450.00 before tax and that is just for the front suspension. You will want to add a shackle and an ADD-A-LEAF for $100 total. So that way your kit will cost a total of $550.00 before tax. I believe that is your best way to go and it will add style as well as keping your truck in great shape. The best way to lift your truck is above, and it will not hurt or limit your regular driving.
