I plan on doing the Crane 1.6RRS 3/8 stud self aligning and Im looking at getting the LT4 Valve Springs. Also I plan on sticking with the stock cam, are the cranes I listed above the ones I want?

Anybody have a part#

Also do i need to get lt4 retainers and keepers or can I use the stock ones?

Anybody know where I can just buy the whole kit?

 

I asked a similar question about a week ago...here's a reply from Stereomandan:

www.gmpartsdirect.com
LT4 Springs(set of 16): 12495494 $26.01
LT4 valve retainer (set of 16): 12495492 $11.26
LT4 valve lock (set of 32) 12495503 $5.83

I couldn't find a kit either. I would go with the LT4 retainers/locks to be safe.

 

Would the LT4 springs require new seats or shims?

 

I know its a bit more, but its WELL worth it to call up Combo motor sports and they have an LT1 spring/retainer/lock kit for springs up to .600 lift for only $99. I bout it and was VERY pleased!

Just my $.02
