What kind of heim joints for 4-Link

[Marcus SC&C]

QA1 (and many others) are ChiCom manufacture,for those who care. YMMV but in my book heims = open header race car. If you want long term durability and quiet trouble free operation you want Currie Johnny Joints or equivalent. They`re rediculously strong, have great NVH isolation with minimum deflection and are grease able. I`ve been running some of them in hard core offroad use for years and they`re still 100%. Heims we had to change every couple years. Same on clients street cars, some of them come in every few years for heim replacement because the owner can`t stand the buzzing anymore. The ones we`ve converted to Johnny Joints are still perfect. Spohn Delspheres are another option, the thinner delrin races transfer quite a bit more NVH than the Curries and they`re only available in one size currently but they`re inexpensive and they should last a good long time.
