Just bought rcsb 07 Sierra v6 future plans are to swap v6 to v8 but I want to lower truck now all companies ask for engine size. Can I buy parts for v8 and will they work with my current v6 don't want to swap motor later and have to replace suspension again. Any help would be great.

 

The v6 isn't real nose heavy so the spring rate is different than a v8. So when you add more weight later (v8 swap) the nose may lower itself a tad more.
Either order v6 or v8 whatever your gut tells you and never look back

 

Thankyou for the info. Do you recommend any kits want 3/5

 

I'd go with whatever brand you favor more.

 

I have a 07 classic also but crew cab.
I have belltech flipkit and Djm coils but soon will be swapping to suspension source spindles and belltech coils. like mention above its all what u like and can afford
