I just bought this Diamond J kit for my daughters blaster last week. Arrived last Thurs. and i installed it in about 2 hours. After all is said and done, i am pleasantly surprised with the kit. It is strong and steady. Not as pricey as a -arms, but a good alternative. The tie rod extension kit is a little goofey, but i made a new set of tie rods at work out of 5/8 stock. I would say its worth the money! I installed on an 03 and i had to get the stainless brake lines. I would buy the kit again!!
But i am a full size adult (165lbs) lol... If it was for me, or my daughter weighed more that kiddie size, i would spring for the a arms. But all in all the a arm mounts (stock) are poorly constructed and really just tack welded on .. so it doesnt matter, the mounts would break with a arms or widening kit.
just my thoughts
So Buy IT!
