Savvy off-road sold? (the unofficial Savvy customer support and Savvy rant thread)

Those the 3.5” Metalcloak springs?

Rk
I get


Almost standing with Metal Cloak advertising by saying 3.5" lift will clear 33-35 tires (37 with high lines). Also weird that the kit has no rear track bar. Not that the price isn't far off once you calculate the cost of the Anti-Rock but the kit sems to undermine everything we have been told about the TJ and its suspension characteristics.

it has a rear trackbar bracket in the photo but no bar. Definitely seems to cater to the general populace that believes lower is better, down travel is more important, need heims for misalignment. Guess it sells well so they’re just trying to make money rather than make what’s actually good.

Heims - for when you want to replace joints every trip off pavement!!!!!
 
using rock crawler springs

I know a number of guys running RK kits and parts. They are very pleased. Does anyone have experience with their springs? I don’t but club members do and don’t complain. I’ve also heard good reviews on the RK joints as well as the Clayton joints. Without personal experience I won’t say but I will say after 3 years of JJ’s in NY all the joints needed major overhaul or replacement.

From my understanding the spring lengths are quite short, same as Metalcloak. Currie offers the longest free length spring which allows for longer shocks for outboarding the rear and for extending the front without the spring unseating. Also the whole "triple rate" crap that just causes bind when compressed.

The more interesting question is why mix up joint styles in the first place. Gerald was around years ago during the Metalcloak shaker table era. Nothing has in physics has changed since then.

The free length isn't long enough for moderately high travel rigs, so they clank around and aren't providing any force on the axle aside from their weight when flexed out.
 
A shaker so big that it needed to be buried underground out in the countryside otherwise the townsfolk would complain about the shaking.
I wasn't around the forum or into TJs when all of that discussion took place (a forum search indicated it took place as long ago as 2019). However, in my mechanical career, we used shaker tables and other rigs to test parts for durability. I became a skeptic of that technology over the years, and I think I've pointed out why on this forum before. Those devices require a very accurate load case to be developed in order to load the part exactly as it's loaded in use. Developing that load case is very difficult, time-consuming, and not for the faint-at-heart. The analogy I would use is that developing the load case is to lab testing as prep-work is to painting. About 95% of the time spent in lab testing should be spent developing the load case.

I became a skeptic because I rarely saw adequate time spent developing the load case. In most cases, what I witnessed was a part designed to survive lab testing. When it went to production, the warranty claims proved that it wasn't designed to survive the customer's use. Load case <> Real world

Man they are just claiming the whole heritage of the name they bought…
