طقم تحويل: من تحميل الأوزان إلى النظام الانتقائي لسحب الظهر والصف المنخفض (سلسلة 4000/5000)

The magnetic pin swap takes maybe ten seconds, and now I’m not racking plates for every warm-up set. Being able to micro-load with the stack instead of fumbling with 2.5s has honestly changed my whole back day routine. Worth every penny if you already own the rack.

Now the whole stack just slides with the pin instead of me loading plates every set — took about an hour to bolt on to my 5000 series rack and everything lined up perfectly. The changeover feels incredibly smooth, almost like it came factory that way.

I was hesitant about modifying my plate-loaded stack, but this conversion kit actually fit perfectly with zero extra drilling. The pulldown and low row movements feel much smoother now, and swapping between exercises takes just seconds.
