can anyone tell me if a limited slip diff is any better then an open diff i want something to replace my rear diff but don't know what to go with i was looking at the detroit trutrac does anyone have any suggestions. its a 98 chevy blazer

 

My 98' S10 Blaser 4x4 has a 342 rear differential and 7 5/8 carrier. I successfully installed a Zexel-Torsen LSD made for GM that is mechanical (no clutches) and is posi when driven straight. The installer tech says its similar to the true-trac but costs a lot less. I've had it over a year and works fine. You will feel the difference. I bought mine on Ebay. Good luck!
