Project Rock-Spider has been an ongoing project of OFFROAD-REVIEW for many years. It's reviewed more products and been part of more projects than any other vehicle we've had. This year we've decided it was time for dramatic change. We've decided to convert our factory equipped manual transmission YJ back to yet again a manual after being changed to an automatic many years ago. The new setup will consist of the popular and bulletproof SM465, Dodge NP203 doubler connected to a flipped DANA 300 at the tail. With upgrades of course. This combination will yield a 185:1 crawl ratio with the versatility of having countless gear options.

Keep an eye on this project as we will be posting informations and articles as it unfolds.
