We like to use the The Ruffstuff 1.25″ Heat & Cryogenically Treated Heim Joints for our chassis links. They are tough as nails and provide a great cost effective solution for any build.
The Cryogenic benefits are many and we simply haven’t found anything detrimental from the process. The Cryogenic process also makes the heat treated rod end and ball harder from further martesite conversion (Talk to the scientists). This process supposedly increases the ultimate radial static load 8-15% but you can safely assume a 78,000lb RSL heim gains 3-5,000lbs in RSL.
FK Rod Ends
FK rodends have been a great partner with Trent Fabrications race team. We have had no issues with them on our cars and have put them thru a lot of abuse, never having a failed joint. With almost 10,000 combinations of rod ends and spherical bearings in stock FK will have what you need for your build. A great product with great service that makes all the difference.
