How to install Yella Terra High Performance Roller Rockers for the LS1 Engine

[@Syrus54]

0.06 is HUNDREDTHS, not THOUSANDTHS... Right???

[@slowpoke96Z28]

If it's 0.06" yes.

[@Slowmo896]

This seemed to miss a few steps, they showed just bolting down all the rockers, and never told anyone to turn the engine over for each rocker shaft for zero lash..I guess it’s known, but some ppl might just follow the directions as it is filmed.😂

Also, has the the breakage problem prone to the earlier batch of yella terra rocker arms been fixed yet?

[@acruzp]

"the instance of needle bearings falling out of the factory rockers is *astronomical*" so 10^10 instances have been reported huh. Marketing..

[@Shadow0fd3ath24]

Shaft rollers are not needed. a simple bushing trunnion upgrade with good geometry is all you need in 95% of engines

[@specialized29er86]

Can we rebuild the heads and then fit the rockers latter before fitting the heads.

I can't find official YT US web page to get an invoice; if someone knows it please let me know!

[@user-yv7li5bg4m]

What size hex key do you need to adjust YT roller rockers? And is it metric or imperial?

I have a 3400 SFI in a 2001 Alero GL2 and I'm looking for ways to get just a little extra HP out of it. I've done the basics like intake, exhaust, fuel and ignition upgrades. I'm just wondering if this would be beneficial on a relatively small displacement pushrod engine like the 3400. I don't take it to the drag strip or anything, mostly drive it like a rally car on the back roads and Im finding the handling and grip to be be pretty good but it could use a bit more pep.

Nitrous. But I'm betting you've blown it up by now ...

[@leam1966]

they worn my guides out and kept breaking. and i put stock rockers on with Bering kits and no problems ever sins..

[@Shadow0fd3ath24]

leam1966 they were probly the basic shitty yellas...the platinum ultras are the good ones but not cheap nor worth it

[@12cwell]

just bought a set a couple weeks ago, finally arrived. my uncles goin to help me install them, i also bought some new pushrods from slp :)

[@charleswilliams4088]

Pushrid length was the same with these rockers?

[@charleswilliams4088]

Stock push rod length?

[@67judge]

I was wondering if i could use break in oil instead of regular engine oil prior to installation of the rocker arms? Or it doesnt really matter.

[@dh5254]

Micheal they are just rockers buddy just make sure they arent dry 😹

[@CHARrrrrrrrr]

Good info provided

[@donrutter6765]

Save yourself some money, replace your stock ones with good trunions, they will handle any cam you throw at them.

[@ReFuzy]

superglide9375 I dont think so. ls4 is a 5.3 and ls1 is a 5.7

[@morgankennedy9823]
