  • Add-on plates work with your original weights for gradual, controlled progression

  • Patented Quick-Lock design keeps locking screws secure and won't loosen mid-workout
  • Screws remove with just a quarter to three-quarter turn, add or swap plates in under 30 seconds
  • Interlocking plates are hand-machined and designed not to disengage when screws are removed
  • Flat screw heads hold plates securely and won't dig into your legs when resting

  • 4x longer locking screws for load expansion
  • Lifetime warranty for the original owner, private use

Usage Tip:

  • Install the larger plates first, then add or remove smaller plates for finer weight adjustments. The longer locking screws support dumbbell sizes from 70 to 120 lbs. Overall length at full 120 lbs: 18.25". The standard Quick-Lock Dumbbell Stand and the Pro Stand 120 holds the full 120 lb dumbbells and includes lower shelf storage for this kit when not in use.

    Duh

    Very few things last forever. Some things are made in such a way that you are confident they will. These fall into that category.

    Expensive but worth it

    Good addition for higher weights, also makes changing mid weights quicker (55 lb just one big plate each side, 55-75 easier as well). Now just need the heavy handle set to come back in stock!

    Very nice plates

    Worthwhile add ons if you're looking for extra weight.

    Don’t listen to the haters

    expensive? Yea, anything worth having is going to cost you something. if you want to have something that is going to last you a lifetime and you have a moderate amount of strength, you will need this expansion kit. Go buy a Walmart set if you want something cheap, buy this if you want to have a pair of dumbbells that will last you a lifetime and help you be the strongest version of yourself, pull the trigger and get these. 0 regrets, but I can also afford these.
