Normally I wouldn't even consider spending that much for what appears to be such a little thing, much less on something that it is not even going to be visible on my jeep, but I must say I am very pleased with my Edge Trail Jammer. I could immediately feel a difference in acceleration. Also, before, when pulling our boat, the jeep could handle it, but barely. Now, there is no question of control. I believe the Edge Trail Jammer is one of the best things I could do for my jeep. Haven't been able to judge improved fuel mileage just yet, but that will just be icing on the cake!
