those are some good looking pieces, congrats on getting them out in time for the holidays. i'm sure there are a few members who wouldn't mind seeing one of these tucked under the tree

Will these work with factory lower A arms??

A quick click to their website gives you the answer. Probably took longer to type your question.

Looks great, price is pretty nice too.

I am thinking about the new complete set up, with the A-Arms what a great price

UMI Performance

Thanks for the comments everyone, we appreciate it.

Like mentioned, stock A-arms will work with this set up.

We hope to have more pictures in a few weeks including installation pictures.

Thanks again!

want someone to test it with a duramax https://www.thirdgen.org/forums/engi...dgen-swap.html

when is the coil over style A-Arms coming?

IROCtheRoad

Great product!

But.... is there any chance we can have custom powder coating done even at an extra price? Sometimes a change from red and black is nice.

I ordered a k member with lsx mounts and coil overs. What coil over kit do you recommend?

lunati397

pa racing has a good kit

89_RS

This has to be the first K-Member I think I've ever seen which actually resembles the letter K.

so what is the biggest benefit for this upgrade? just weight?

lunati397

weight and clearances for headers turbos motor swaps

babadioum

Thanks for the extra 5% but I do not see the 15% preorder discount?

UMI Performance

Coil Over a-arms are coming next, they will be identical to our current a-arms but will have no spring perches.


We can do custom powder coating to an extent. We do all powder coating in house so that isn't an issue. The problem we are having now is our current supplier now has minimum purchase pounds on the powder, so custom colors are getting expensive because we have a lot of powder left over and expires overtime. If you serious about a custom color let me know and I might be able to work it out for a charge. We have silver on hand at all times.

Thanks for the order! We have a coil over kit in the works right now and it should be available shortly. So if you can hang in there it might be ready when the K-member is completed.

Our sale ended yesterday but I will work on getting special pricing on the site for this item. We would like to get a few more pre-orders. If you are ready now send me a PM for pricing. Thanks!

dctrouant1995

Sweet can't wait to see them

babadioum

oh I am ready, it is just that I have to make a decision in terms of oem or UMI because this part will be shipped 10K miles overseas where I am posted and the shipping price is of enormous consequence since it will be a huge chunk of FOB pricing. So can you email me (as opposed to continuing the thread here) a quote for 2401? I am hopefully expecting the same discount that was availbale few days back which was a total of 20% including an additional 5% third gen member discount; then we can look into the international shipping quote you can get for me to find out FOB pricing. Thanks so much in advance.

There is no mention of what these are made out of. DOM? Chromoly? Strength is a concern as always with these, so i'm curious.

89_RS

Says on the UMI site they are made from mild steel. Kinda need to be mild steel if they are MIG welding them (nothing wrong with MIG welding BTW). This is the heaviest constructed K-Member out there. No other K-Member has a second tube of steel in its hoop to brace the A-Arm mounts.

UMI Performance

The tubing is DOM. We may add a chromoly option in the future, however since the item is mostly fabricated from flat steel the tubular components would be the only chromoly part.

I hope that helps!
Ryan

89_RS

Is it cost prohibative to use chrome moly plate steel??? Seems to me its the same price for 4130 sheet as it is for A36 or SAE 1020 sheet.

85TransAm406

iTrader: (1)

Since 4130 plate is the same weight as mild steel plate, it wouldn't impart any weight savings, only increased cost. Remember, 4130 tubing is only lighter because you can have a thinner wall thickness with the same strength.

89_RS

I'll buy that. I thought I was pretty upto date with material prices. Just looked it up and 4130 is nearly double the price of mild steel.

rlewi771

Thanks, this looks like a great piece

im very interested in this. is the sale still available on this?? im also interested in coil spring a arms

Birdstheword

does the engine remain in the same position as OEM ? , or is it moved forward like the BMR k member ?

UMI Performance

We just placed the K-members back on sale under a pre-order price of 20% off. The "Thirdgen" code is no longer valid but instead we just placed the k-member at a straight 20% off.

Our K-member will keep the engine in the same location as factory, there is no moving of the engine. This way your current transmission crossmember and drive shaft will still work and fit correctly.

Thanks for asking!

great deal. is the shipping still the 9.99 or is it different? now all i need is a sale on the a arms.......lol

UMI Performance

Customer will pay shipping but we increased the discount to 20% (Rather than 15% off then another 5%), it comes out close to the same.

I hope that helps!

i ordered mine on the 8th. cant wait to get it so i can finish my engine bay

UMI Performance

We didn't forget about any of your orders. We are on this project everyday and getting close. Jerry, Ramey and myself are working out some minor issues that arose, we will be posting some updated information shortly.

Thanks!

im sure it will be well worth the wait. the parts i already installed are flawless. cant rush perfection. thanks for the update,

dose anyone have one of these installed? they take 3 weeks to get still?

Project-RS

iTrader: (1)

im still waiting on mine and i ordered it dec 8th. i believe they are finalizing the finish product

UMI Performance

We are still working on them, we had a few bugs and tweaks to work out and trying to get them into final production now.

We will keep you updated!

UMI Performance

Just another quick update. The k-member is heading to full production, we worked out the tweaks and fixed a few things we didn't like. The few pictures below show some of the exhaust clearance and fitment.... nothing fancy but they help give you an idea.

While the machine shop is beginning to build the production pieces the design crew is finishing up the LSX mounts.. this won't take long.

So we are getting close and want to thank everyone for the patience.

Christina, who handles all our marketing and advertising here at UMI is currently building an 85 Camaro Z28, the goal is to have it completed before mid April for the Spring Carlisle event. We will be installing and using a full UMI suspension including the new front k-member assembly. We will be posting pictures of this build soon so stay tuned!

i hope my full length headers dont have an issue

toomanytoyz

Man, I still want in on this, Ryan... I think it was my turn to respond to the email we had going. I dropped the ball. lol. Was one of the "tweaks" fixing the AC compressor clearance issue?

-AO-

Expect a call from me on Monday. I'm gonna order a SBC K-member and A-arms for coil springs. All in black. Thanks for making quality parts.

UMI Performance

A long tube header shouldn't cause any issues at all, there will be plenty of clearance for this so no worries.

In order to run A/C with our LSX k-member you will need to find a truck A/C unit or something that bolts into a different location. The other option and best option would be a relocation kit like Kwik Performance sells. This will relocate the A/C to the top and away from the k-member. After some time we are unable to include A/C clearance with our design with out effecting the integrity of the part. Also after some research and speaking with some customers many people ditched the A/C when doing this swap, many mentioned the challenge of running the lines and converting it was too much. Others mentioned they had no desire for A/C. So A/C will work if relocated upward, we figured if you are going to the extent of this swap a few extra dollars to relocation the A/C shouldn't be an issue.

Thanks again!
Ryan
