Start building a desert race truck rather than a rock/mall crawler and it may make a difference. On our 330 lb race car we have to find ways to cut every ounce out of it![]()
Light weight is everything for performance in pretty much any motorsport, save tractor pulling etc.
Most four wheelers don't care, and honestly, it really doesn't matter until most of the ultimate parts are in place: big tires, lockers front/rear, deep trans/t-case gearing, etc.
But once all those things are maxed, the lighter vehicle always makes everything easier on parts, more reliable and more capable. But, of course, big tires, strong axles, etc. kinda lead towards a heavier vehicle. It's all a balance.
. Plus I have a friend who works at WOD hense why I wouldnt order from branik, I could get my buddy to make me a set for probably less that 4130 and tube adapters. That being said they still cost mucho bucks.
