Been running the 2110’s for about 10k miles. Tooley springs, 236/240 .630/.630 cam and 7k limiter. (346 LS6)
Can’t say LS7’s wouldnt have worked but I think they are an upgrade if you’re gonna have some spring pressure and RPM.

Corvette forum Johnson 2110 lifters
• In late 2013 GM Performance went to Johnson Lifters to ask them what they had for their COPO LS engines.
o GM tested the Johnson 2110 lifters, GM LS7 lifters, Cadillac Racing lifters, and others to include those from Morel
o GM took the lifters and put them through months of testing, and the Johnson lifters were the only ones that they had no issues with axle retention.
o Johnsons were repeatedly tested past 8,500 rpm
• Slow bleed-down lifter describes the ability to maintain lift without collapsing, or the repeatability in common rotation on the cam:
o If you had a .630” lift camshaft but your lifters bled down .030” as the lobe of the cam rotates, you essentially would only be getting .600” of lift from your cam
o GM found that
• Johnson lifters maintained their lift 95% of the time
• LS7 lifters only maintained their lift 50% of time
• Cold Start noise is commonly attributed to two main factors:
o High valve spring pressure
o The high leak (bleed) down rate of the lifter (SLR lifters are actually a positive here)
• Johnson lifters have the largest inlet from low pressure (engine oil pressure) to high pressure (holds the load via the pushrod to from the rocker arm)
o Johnson uses the largest disc style check valve in the industry
o Cadillac Racing lifters previously used to have the largest inlet with their ball style check valve
• Cold forged 1018 steel blanks CNC’d to final dimensions. Heat treated for exceptional wear resistance. Chosen over 8620 for roller pocket strength. The grain structure from forging increases the durability and dimensional repeatability in that area, which allows for an encapsulated roller versus an open fork design. The encapsulated rollers when used with standard GM diameter lifter will take higher spring loads than an open fork design
• Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction.
• Cold forged extra long piston, precision ground and fitted for controlled leak down and pump up.
• High flow disc style quick reacting check valve for better reaction at higher RPM.
• Precision oil metering assuring proper oiling to the rocker arms without sacrificing oil pressure.

LS7 for single springs up to 300-320lbs open pressure would work fine...
Johnson 2110 for Dual Spring which are usually around 400lbs open pressure...
Its not that LS7 wont work with dual spring kit, but they have more failure with high pressure springs and bleed down easier.

I've used both LS7 and the 2110's up to about 7800 RPM without issue. I also had the Lunati link bars before the 2110's and I had multiple fail under 7,500 RPM so I wont bother using those again. 2110's are still going strong, great option for the price!

I like the LS7's for the money they are an excellent value but I will be switching to the Johnson lifters next cam change for the next motor project.

Im changing lifters, will 2110R be a lot better than 2110? Im undecided and need a little more feed back on the two types.
Would extra preload on a 2110 be a trade off, i dont want my lifters to be bleeding off at all at 7000rpm.
I assume that once 2110R are setup, there go to go!
Your thoughts...

I doubt that the Johnsons would bleed off at 7000 rpm. People push LS7 lifter past 7000 rpm frequently.

I wondering if 2110R are really worth it or will 2110 be perfect for my cam and setup. I just want to make sure im getting everything out of my cam performance wise.
Maybe ill give Johnson a call pick there brain.

Im already pushing my LS3 to 7000, Ls7 lifters are in the LS3.

Would it be worth going with Johnson's over LS7s if I'm only going to rev to about 7000 with a Torquer V2 cam?

I'm running the 2110r lifters and currently shifting at 7500. Pulled it to 7800 on the dyno with no valve float.
