Are Jegster bolt on subframe connectors easy to install on jack stands? 1987 camaro irocz american thunder full exhaust no cat.

When installing ANY SFCs, the car's weight need to be resting on the suspension.

So if you did it on jack stands, 2 would need to be under the rear axle & 2 under the front a-arms, but I don't like the idea of the front a-arms on jactstands. Just strikes me as not good support for being under there.

Maybe the front up on ramps, then the rear on jackstands, but I'm not sure that the chassis wouldn't flex by 1 end being lifted independantly of the other end. Considering that the function of SFCs is to hold the chassis in a certain place, I don't like the idea of flexing the chassis to a different position & locking it in that position, once the SFCs are put in place.

I wouldn't trust ramps seen a few break,If you haven't bought the sfc get a weld on set they are stronger then bolt on or weld in the bolt on ones.I would take it somewhere with a wheel lift and let them put it on.

Can they be installed in a flat driveway?
I have limited access to any shops at the time.

Try to get a lift. The hardest part is drilling the holes in the floor to bolt it in. Your going to need more space to get leverage down there. Also to Make it easier and roll up the carpet up front first.

Too much work. LOL
I'll save up and get weld-in ones and have a shop install them.

Im the definition of "bean pole" and i still dont think even i can squeeze my scrawny @ss under a 3rd gen without a jack or jackstands LOL. Thats a tight tight squeeze

Jegster are super easy to install

redneckjoe

im very happy with the fit of the jegsters. you can weld them later. my t-tops used to make noise coming in the driveway. once i installed and welded the SFCs, ive never had a squeek. big diff.

J91

You can do it in a driveway on jackstands. They fit well are easy to install, and you can have them welded in later. I am always amazed at the amount of nayusayers on here. It's not a hard job and can be done quite easily....

vortec350s10

I agree, not very tough to install, bolt in and weld later. Good fitment, I'm very happy with them.

Any pics of these subframes installed?? Im in the market for some

Mr.Franco

I really like the Jegster SFC. They are easy to install (as mentioned above), fit well along underside of frame rail, give a good jack point/body stiffness and only weigh about 15lbs.

I reccomend welding them in place (which is a cinch)!

vortec350s10

Not the best pics but I found a couple. The pieces going from the side subframe connectors to the trans tunnel area are pieces I added later.

Do the Jegster ones fit in conjunction with the Alston inners or do they interfere?

I bolted in my jegster subframes while my car was on ramps and jackstands. i have yet to weld them but i do check the bolts everynow and then. i also put on a set of topdown solution tubular subframe connector with no interference at all. the car is as asolid as it can be.

You had to drill holes?

tonys91rs

iTrader: (17)

yes for both sets.

BlueWrath92

iTrader: (1)

Hows the driving after putting them on? is it pretty stiff around corners?

JunJun

How hard was that drilling?

FueledSoul

iTrader: (18)

All you do is bolt them in on the rear lca munt and swing them up into place on thefront rails/floor pan and support them. You can either drill using the subframe holes as a guide or mark them and swig them back down and drill just make sure you have your carpet pulled back ect....

Mac10

do the holes come up in front of the seat ? , or maybe there is a chance you will put a drill bit into the bottom of the seat ? Pics!

blakecharles

so will the jegsters fit convertibles??? been seeing mixed reviews.

Too bad they don't actually connect the subframes since they are not actually even touching EITHER subframe on the car. They are just a still bar that bolts under the car & I question how much they actually stiffen the "frame". I'm sure they help but SUBFRAME CONNECTORS they sure aren't.

The UMI design is much better with 6 major weld points.

Look down at the bottom of the page and click on the photos.
They cost more than the Jegsters but are far superior in design.
UMI makes excellent products and those are the sub frame connectors I will be installing.
Here's the link to the Jegsters so you can see the difference.

i have a set of jegster bolt ins in my car. i welded them in and added some extra braces like vortec350s10 did.

here's how i put the car on jackstands whenever i'm doing sfc's...this is InfernalVortex's car from a few years ago when i put spohn sfc's on his car:

Ron U.S.M.C.

The only reason I beleave the UMI has such a good design is that it directly addresses the twisting of the uni body where the problem exist. "vortec350s10"seems to agree with his alterations,and BlackenedBirds comment just enforces that. I am not a racer so I don't know the exact demands on a Third Gen. with a straight launch.
I am simply helping the OP make a educated decision with his purchase. If he has his mind made up already than none of this makes any difference.

Ron U.S.M.C.

Not trying to be a jerk,and it may work but you still could not pay me to clime under a car with the front stands like that, I don't care how many times it been done.The lower control arm is just on the other side of that wheel and is considered a jack point that will accomplish the desired effect.
Nice looking car "InfernalVortex"

i figured i might get someone giving me a hard time about it, as it does look a bit sketchy. it's stable, and keeps the suspension 100% loaded. a drive on lift would obviously be better. the jackstands go under the balljoints now, just for extra piece of mind though.

I always do the shove test in all four corners when a car is on jackstands. If it passes then I crawl under.

jegsters weld to the rear LCA mount, doesn't get any more solid to the forces being applied to the chassis than that point. I like the set in my car.

carattini

I'll like to build ones like this I have the tubing and a Wellder just need the Blueprint of thees connectors do you have anny?

Straight from the horse's mouth:

bungy74

wow, i am glad someone told him about that dangerous jack stand placement. I always leave my floor jack under the front crossmember also, and put a little pressure on it for peace of mind. Safety first !

BlackenedBird

iTrader: (5)

For the rear mounting point.....The Alstons will & are the only ones that actually attach to rear subframes. All the others simply attach to the rear LCA mounts.

As much as I love my car, If I aint around, no one is going to love it anymore.

Q:
Can LCA relocation brackets still be used with SFC's?

musicfreako

iTrader: (1)

put a strap between those to front jack stands. that'll hold em' in nice and tight. Then your set!

musicfreako

iTrader: (1)

I too have the Jegsters. Bolted in and then welded. Love them. Even fit up under the 3" exhaust.

mw66nova

iTrader: (13)

Yes. Lca relocation brackets weld to the rearend, not the car.

xpndbl3

iTrader: (5)

and where do you think all the forces on the rear of the car go exactly? The LCA mount is what is pushed/pulled during acceleration and braking at that exact spot, not the "subframe" back there. IMO the lca mount welded subframe is superior .

BlackenedBird

iTrader: (5)

Yes, forces from the tires/LCAs do go through those mounts. But do you really think that the LCA mount is actually stronger than the engineered "frame" of the car?

xpndbl3

iTrader: (5)

yes once you weld that thick steel to it I sure do. Not to mention that the subframe is on the same piece of folded over steel if you look at it under the car and a few inches inward. I cut into all that crap when notching my frame for mini tubs and it's stupid thin.

JunJun

I was told the same thing at a shop.

The subframe part is thinner compared with the LCA.
I can also tell that by hitting each with a screw driver's head because the sound is quite different.

Also, in Alston's case, they said the distance between each cup is short compared with the LCA type and that will make it a bit harder to play its role.

But anyway this is just a theory. For now judging from many people's opinions who use them, I think we can say both are effective.

Any subframe connector is going to benefit a unibody car.

The difference in the design and the related difference in effectiveness is probably so minute you would never even be able to notice.

so whats better, weld in or the bolt on ones?

Weld in.
