#inb4"ls7liftersaretrash"

 

I need to make some other calls, maybe to Tick and Thompson Motorsports. A bad LS1 lifter took my motor out so I have lifter PTSD. I'll pay for good lifters. Cheap insurance not to have it randomly explode on the way to the local brewery and send the roller tip around my engine.

 

Don't get your Johnsons crossed.... never turns out good.

 

Understandable, if that's the case a really great lifter that provides superior performance and durability to the ls7 would be Johnson 2110 lifters. My question would be, are you sure the faliure in your case was due to lifter defect/design or was there another issue that then caused lifter faliure?

 

Couldn't tell you. All I could see is the roller tip broke entirely off the lifter and in-turn got stuck in the bore. I am building an LQ9 so we will see. I spoke with Tick and they were going to send me a recommended lifter today sometime.

 

We have some awesome lifters made in the US with the same dimensions as the LS7 to make them drop in ready, Just better parts and tolerances. They are $159 a set. Let us know if we can help. We also have dealers nation wide that inventory them we can refer you to if you need something more local. Please give me a call if I can help.
Thank you,

Who makes them?

 

Eaton

 

I wouldn't doubt Eaton makes GM's too.

 

Good stuff, I've received ones marked eaton before and no issues.

 

I did not have great luck with the GM Performance LS7. I went with Rhoads VMax in my current 383. I also have a 305 with the standard Rhoads design. The standard design also works in a non adjustable valvetrain. The more I play with them the more I like them. You can over cam the engine to an extent to get more HP and still have a nice idle, good low-end torque and higher average torque numbers.

 

I got tired of pulling heads so I went Johnson 2110LSR's. I am now going with ST2126LSR's. I avoid LS7's with big cams but for an LS1 they should be ok with a .600 cam.

 

I'm no expert but compared supposed genuine GM LS7 lifters sold in bulk and the same lifter sold as a set of 16 in a GM box. I'd swear they were apples and oranges. I went with the set of 16 in my current engine. They appeared to be of higher quality and they are quieter than the Morel drop ins in a previous engine.

 

My LS7 lifters came in a boxed set from a GM dealer.

 

They are not he same lifter. We keep the GM and Eaton in our sales office so you can hold them side by side. There is a difference even in appearance and finish work as well as the components like c-clips for the axle rather than a pressed axle. They are the same dimension to be drop in, The similarities end there.

 

The fancy $500+ lifters look nice in the showroom too, except they break before the OEM design.

 

I ordered me a set of the TMS lifters. 170 shipped to my door, reasonable enough for my Torquer V2

 

Not doubting you at all, but I bet Eaton will make whatever their customer wants. You might even have 2 Eaton lifters in your office.

 

LOL, I see what you are saying.

 

I read a quote as a kid that said “GM doesn’t make parts...they make cars”
Makes sense if you think about it. GM bids it all out to the cheapest bidder and it all gets shipped to the plant for assembly. Who knows who really made the part with the GM part number on it?
