Suspension was 14 yrs old... so i renew it completely. The other reason is new setup can handle a lot more weight with no problems. I got an 85 kgs roll cage inside, rack, ladder, and underbody protection - all that stuff have weight.
But now when i put winch bracket on front, suspension didn't notice that.
all that stuff that have now is about 185 Kg add. With winch it will be about 230 Kg of extra weight. Suspension need to handle with that. Most important thing is proper spring.
