I have had this kit for over 12 years now. The only difference is I changed the caster bushes to a rubber equivalent that's better softer for my ride needs. Also, the older kits were made in Australia where it's been said is not the same quality now being made in China now but I have no experience myself. OME was once probably the best go-to but over the many years in the year 2000's but since I have learned, there are better options in the last 5-8 years.
I find the spring rate on mine even with the soft ride model ride harsh over bumps. I bought the vehicle when they were already on but I would prefer the original Toyota ones.
Your need requirement is critical to the options best for you.
