Hi, does anyone know if there is a difference on the springs of the KB1 and the KB2 ?

Thanks a lot.

yes. the kb2 had higher-rate coilover springs

now if you're asking if you can mount the KB2 springs on the KB1, sure...you could transfer the springs over to the KB1 shocks/struts....
or you could compare the mounting points of the KB1 to KB2 and see if it'll mount. I dont think Acura changed the mounting points, as its the same exact car

Reason I ask is because I am looking for some lowering springs for my Legend KB2 (same as Acura RL KB2), and I can only get the springs for the KB1 here in Europe, not for the KB2.

But I want to make full sure if I can use them or not, before ordering

Yeah but the axle weight on front could be different ... hmmm

KB1 and KB2 suspensions are interchangeable. H&R will work just fine at the best price. It's been done here more than once.

rimini4321

Cool, anyone know the axle weights on the 2 models ?

oo7spy

Are they different part numbers?

rimini4321

Yes, at H&R they claim its not the same springs, because of axle weight, I just ask the experts here

037 was one of the first to mod a KB2. Check here: https://acurazine.com/forums/2g-rl-p.../#post10906907

Something in the back of my mind is telling me there are two H&R part numbers for the different chassis, but I can confirm the parts are cross compatible.

rimini4321

Yeah, they are called 50116-1 and 50116-2 .... H&R says they are not same and the 50116-2 actually have to be manufatured after ordering ... but I see the link you made and it looks fine .... hmmm

What suspension are you guys running on your RL

Hi, I can confirm that the H&R 29157-1 for Legend 2005-2008 is Fitting KB2 and so does the Acura RL 50116-1 suspension...

I have just mounted the 29157-1 on a Legend KB2 with good result
