4/4 Drop Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BigMike608 · 07-22-2012, 12:23 AM

After much consideration and debate, I've decided to do a 4/4 drop on my 87. Currently it is stock height and I have 275/60/15 on all 4 corners. My question is can I do a 4/4 drop with the 275/60/15 front and rear without any issues for now until I eventually upgrade to 20s or 22s?

Shouldn't be an issue. That tire is only 28 inches tall, the tires on my 22s are 28.5 inches tall and I have like a 6/8 drop.

I did a 3/3 drop on my friends truck and his tires are 32 inches tall, he has room to go down another inch at all corners.

Ok thanks, I appreciate your feedback. I was worried that the tired may also be too wide for the front. Which option would give me the most accurate drop because I know drop springs tend to offer more drop than advertised once they settle?

Option 1: DJM 3/4 kit (3" spindles) and Belltech 1" drop springs

Option 2: McGaughys 2.5/4 kit (2.5" spindles) with McGaughys 1" drop springs

A lot is going to depend on which wheel your running. I have a 15x8 rally and the largest I'd run on it is a 255. Turning full I'm still touching the raised white letters on the back side of the tire. 3" spindle and a messaged spring.

I have my stock 15x8 rallies on both front and rear

I would cut your stock coils for a 1" drop. Half coil = 1inch. Its going to give you the best ride. Along with the 3" spindles.

thanks again, sounds like a plan. Both DJM and Belltech offer a 3/4 drop kit, is one brand better than the other? Ragardless of which kit I use, I'm definitely going with the nitro shocks

DJM is cheaper, as far as shocks go. Check out the beltech Street Performance shocks they are freakin awesome.

I've been reading up on them, what's the big advantage those have over the nitros?
