I did mine two yrs ago and Kodiak discs/Carlisle actuator was the most popular choices. Titan didn't have their kit ready for market yet. I'd use Kodiak or Titan discs and probably the HBA 1600 psi actuator again cuz I like the small footprint of that actuator. Inner Bearing are the same 5200-8000 lb axles but the outer bearing gets bigger with each axle rating. Just be sure to get at least new seals and the outer bearings. I put together and built my own hard lines, mainly cuz I'm so fussy. I would check out all the vendors that sell the complete kits. I'm in Minn right now or I'd give the names of one that I know. I also like the oil covers that came with my Kodiaks. Craig
