K-members

[Bruce Hemminger]

Who's do you all like? What are they worth used?

[Eugenio_SS]

english... please !
on a more serious note... you asking about stock k-member ? how much they are worth ?
if you are looking for aftermarket, i'd stay away from BMR ones... I'd trust the stock one WAY more.
The only good alternative k-member that can take the abuse and be able to handle cornering withouth the whole front end collapsing would be the UMI k-member.

honestly how many times have you seen a k-member collapse, did it happen to you, if so pics?

i'm getting ready to purchase to bmr k-member it is 5 lbs lighter then others and at the same price, the advantage with these it that you gain a lot of clearance under the car, so it you do your own wrenching this may come in handy, plus its a total of 35 lbs off the nose with a-arms

its not a wear item so buying one used won't save you muck if you can even find one.

i have the bmr k-member, upper and lower control arms. no issues yet. drive the car everyday. i'll keep people posted.

apparantly, bmr has had a few crack.

umi makes one that has two cross bars, instead of one.

here's the bmr i have

I had a lot of input on the UMI K-member. Check it out and tell me which you think is stronger: http://www.stranoparts.com/partdetai...D=18&ModelID=7

Remember, all the lateral load generated by the car is put into the k-member since the LCA's are bolted to it. Hence the reason for the double cross-tubes, and on the RR version the gussets. Yes, a UMI one is heavier than any single tube k, for obvious reasons. But there are just some places I think that you need some beef. I woudln't want an aluminum crankshaft...

Agreed, I have the RR version on the way from 'Santa':

from the looks of it i think the umi is better also, you still save 25lbs and get a stronger part. Time to get the debit card out.

ok i'm searching for a thread that talks about changing the k-member. Any one out there wanna take a shot at explaining how you would change the stock k-member for an after market, like UMI, Spohn, etc.

How would you support the motor and trans?

thanks

[mrr23]

they make an engine cradle. basically, it's a bar with supports that sits on the inner fenderwell railing. then, you chain the motor to it.

here are pics of my motor swap. i pulled the motor from the bottom. it'll give you an idea of how to do it.

yeah i saw your picks on the web site. BTW, nice swap.

I was wondering if the k-member could be changed without pulling the motor.

since i have a nice camaro w/ full under body coating i have no reason to really part with it. so that leaves me with lots of parts and bushings i would like to replace. I figure I would work on the hard things first, like the k-member. I loved abusing myself so much on the motor mounts, why not donate a little more blood.

And I bet it made it real easy doing a motor pull on your lift... very nice doco on the web site.

thanks

I noticed that in a few of the pics there are very solid looking rod ends. How well do these work on a daily driver? (comfort and durability)

yes it can. that's why i talked about the engine cradle. it'll hold the motor up while you drop the k-member. you could also use an engine hoist.

makes the ride much more responsive because there is no rubber bushings to move around.

any idea where you can find an engine craddle? I figured a hoist would work, but don't have one, yet.

harbor freight. the last one i priced out was $175.00

ah, should have known. Every one goes there for everything, thanks.
