With the third wheel set on the suspension,I feel should have been equipped from the factory due to the span between wheels,I would be more assured to less resistance and wear longer slide life with the kit.Currently my sled has stock slides on it although I did purchase a set of Duponts for the next round.Overall you mentioned you have the Pioneer kit,have you noticed a improvement with slide life with the kit,or ay other beneficial factors so to speak.I reviewed the Excell wheel kit and am leaning more towards his set up with complete wheel set up and centers,any give or take on that kit ????? Whats your thoughts about them ????
