What's involved with the kits and durability........are they durable?
I used to include 6 stainless steel washers per kit and realized that these have a greater degree of off set than the OEM rod and was unnecessary. Now I include just two washers one that goes behind the Rose joint and in-front of the ball joint lock nut.
Durability...........great question.
First the company I use for the tie rod sleeve (which honestly is the most important part of the kit) put a million mile limited warranty on the sleeve. There isn't a more durable part on the Maserati that I know of. I think we have spoken indepth about this before. That sleeve isn't built for the Maserati it was built for the dynamic load forces of the front of a fully loaded one ton truck. I am confident of it's ability to last the life of the vehicle.
Heim Joint/ Rose joint. This part of the kit isn't anything new and I'm sure you guys in racing/ 4 wheeling have seen them before. I wanted the best one they made period. They were deemed to be an ultra high performance end. Applicable for racing and marine applications.
small tid bit about them:
The body is machined with a significant groove going all the way around the interior of the body. The ball is then inserted into the machined slot and a Teflon®/Kevlar® material is injected, serving as a liner to keep dirt and debris out, while also lubricating the rod end. In addition to providing added strength, the injection moulded race also won’t “pound out” like traditional PTFE (Teflon®) liners, increasing the longevity of your rod ends. The body is heat treated and is made from Chrome Molybdenum for excellent strength and corrosion resistance.
