Durablue Eliminator +2+4. Best axle money can buy. Thats what i run and it gets a beating into the ground everytime i ride on it. Yes they are like 500 bucks (got mine for free:iagree But WELLLLL worth the money. Ive ran a g force before and my buddy had one. We both bent them farily easy, not much stronger than a stocker. DURABLUE all the way
