ECS is one of the only tuners who hand builds rear carriers in house. Why? Quality Control. Many shops will sell you a used carrier with, who knows how many miles and what kind of prior abuse. Not here. At ECS we only use the best materials and parts. Micro polished gearsets, hardened shafts, new seals, reassembled in your own carrier. No questionable parts, set up by hand and guaranteed.
