I used a different brand on my YJ, from Rockauto, dont remember the brand, but they have grease fittings.
If I wheeled hard, or had a V8, or larger than 33" tires, I would probably upgrade the parts.
On the other hand, my 8000lb F250 got all Moog or OEM Motorcraft parts when I refit the suspension. Truck rides on 35's, 476hp, 812tq, tows up to 15k regularly.
For comparison, a daily driven, 150hp, 3000lb Jeep probably doesnt need heavy duty parts.
See where Im goin with this?
