I had my Jeep, a 2015 Wrangler Willys modified within the last couple of months. The decision to use Boston Jeepz was via word of mouth - a decision that has proven utterly correct. The bespoke suspension upgrade has provided vast improvement over the stock Jeep system. In terms of on and off road handling, stability and "feel". The ride is transformed. This Jeep now drives the way it should. I would not hesitate to recommend Boston Jeepz - in addition they are a no nonsense source for Jeep repairs done right. Boston Jeepz- There is no substitute!
