Rock Krawler vs. Teraflex
#11
I have seen posts on here about the arms squeaking but never from someone that has them. LOL. No squeaks to report. The stockers didn't squeak and does not require grease either. I don't see how you could get more articulation from one brand of LCA's vs another. They bolt from point A (axle) to point B (frame mount). If it's a long arm vs short arm LCA, the articulation would then make a difference.

Mine have squeaking from time to time. I usually spray the rock krawler joints with pb blaster from time to time and it fixes it. If it hapens, its very minimal. As far as articulation, the ball end of the RK joint or other similar styles MAY give a tine bit more of room to flex but it comes down to your coils and more importantly, the lenght of your shocks.

The asnwer to this is difficult. Here's why
What is your setup? Are you running aftermarket bumpers and winch? RK uses progressive rate coils so a 2 door running stock bumpers will see a ton of lift from the 2.5" coils. My buddy has that setup and he sits an inch or two higher than my 4 door running 3.5" coils since I have aftermarket bumpers and winch. The progreesive rate coils, in his case, have zero compression at the top 3 wraps where mine are fully compressed. That lack of compression on his coils pushes his Jeep up around 2" or so over 2.5". So he's having driveline issues now!
Also, RK does not make specific kits for 2 door or 4 door. The coils are the same so a heavier 4 door will yield less lift over a 2 door. However, even with a heavy 4 door, the amount of lift you get with RK will be more than the stated height. My 3.5" is proabably settled in around 4"
Teraflex makes it interesting. After 2010, the started selling 2 door and 4 door kits separately. Prior to that, their kits were like RK so 2 doors were seeing way more lift that what some people wanted. So TF addressed that so now 2 door JK's have a choice. Buy the specific 2 door version and maybe net 3" out of it or but the 4 door version and get maybe 3" to 4" of lift (maybe more??). Teraflex uses linear coils so those don't address heavy bumpers the same way progressive rate coils will. Depending on your setup, when heavy stuff is added, that will have more impact on net ride height than RK. Think of it this way, the RK 2.5" coils are probably longer than the TF 2.5" coils but the progressive nature of them bring the overall height back to around TF height. But individual setup will impact how much height everyone ends up getting.
With the control arm situation, both companies ues their own style joint ends. TF requires regular greasing and RK does not. Which one lasts longer? Who knows. They are both super beefy and I believe have great warranties. I prefer the RK design for the higher clearance. But I do a lot of rock cralwing and that might not suit everyone's off-road style.
