correct me if im wrong do the lsj's have the fe3 or fe5?

also anyone know the parts numbers for the shocs

 

As far as I can gather based on the GM parts catalogue sites, they're FE5's and they list them based on model years (2005-2007 SS/SC and 2008+ for SS/TC). Kind of like FE5 version 1 and 2.

 

• FE3 suspension – standard and available only on SS models, it delivers a firmer, more direct ride and includes 22-mm front and rear stabilizer bars, four-wheel disc brakes, monotube shocks and 17-inch wheels and performance tires


• FE5 suspension – standard on the SS Supercharged, it was developed on the racetrack to deliver sports car levels of handling and grip; 24-mm front stabilizer bar and 22-mm rear stabilizer bar, higher-rate springs and bushings, four-wheel disc brakes, monotube shocks and 18-inch forged aluminum wheels with complementing performance tires

^ Straight from CrateEngineDepot website...in other words almost every LSJ should have FE5 setup

Rear shock part numbers:
Item #22728821 2005-2007 60.10 each plus S&H

Item #25793745 2008+ 61.45 each plus S&H

 

i like how one shock is more then the other hahah

 

Yeah I know, it doesn't seem to make much sense. They're pretty much identical. I'm sure there is not much difference at all between either one performance wise.

 

anyone know the part number for the LSJ intake manifold and throttle body?

 

I guess that's what happens when you use vague thread titles...

Anywho, everyone keeps telling us that the SS/TC suspension is far superior to the SS/TC suspension; Couldn't tell you. There could be truth to it, or it could be total BS in an attempt to make the SS/TC look more impressive all around. If you dig around here, I know somebody has posted spring rates and stuff for both suspensions, should give you a good idea.

I'd take with a grain of salt the guys that have done conversions and say it's better, since they've gone from suspension parts that were probably pretty much shot to new parts.
