I'm just saying as good as an factory engineer is.... they have to work within a set budget and usually with a part that is already available off the supplier shelf. I highly doubt gm actually r&d a single tie rod. Seeing as they don't even make it them selves. They call a supplier and say what they want and what specs it must meet. Keeping within factory angles and specs is what is keeping your parts alive not superior engineering. I sell auto parts for a living. I will taken gm factory tie rods to pieces as well as ford and dodge . I've compared the. To our Moog and mevotech and i gotta say you can see higher quality work in both aftermarket brands.especially mevotech new terrain tough line of parts.
CanucksRedRocket,
You are absolutely correct. GM does not design their tie rods, they create criteria for angles, range of motion and tolerances and bit it out to whoever can make they quantity desired.
You are also correct that the 100% factory angles and specs of my suspension that keeps the parts alive for the most part, I still manage to destroy many parts just from pushing them beyond their limits on daily basis. Tierod sleeves have saved me trip after trip and I would highly recommend them to anyone that wants to run 35" tires on their GMT800s or 33s off road, they will save a trip.
My factory tie rods have been great so far, knock on wood, several of my GMT800 and GMT900 friends have snapped theirs on the trails with me and they were lucky that I always carry two spares just in case.
Rear sway bar links are a different story however. I managed to get about a year out of my factory setup after 3" coil spacers and 37s. When I popped them I replaced them with Moogs, due to the stellar reviews and the fact that they looked and felt better than OEM.
Left is drivers side, right is passenger side. Moogs rear sway bar links after 4 months and approximately 7,000miles.
The nut that came with the Moog sway bar links internally stripped and broke off on the trail.
Actual bolt shearing off on the same trail on the drivers side sway bar link.
Moving up in the world, I just replaced them both with Mevotech, hoping they last longer. Hopefully they will last longer than OEM or Moog.
Thank you for following my adventures and carnage as well as giving me ideas in which direction to go, many more adventures and much more carnage to come soon.
Stay tuned for more shenanigans!
