How much is too much

[RIPPEDK5]

I am trying to figure out how much drop is too much drop..


I am aiming to drop my transfer case (via: the crossmember spacer)..

I have square tubing that i will drill ... How much is too much to drop?

How much does it affect the motor mounts?

I planned on using 2" x 2" square tubing and was interested if that was too much?

any thought or insight is appreciated

IMO any drop is too much drop.

Why do you want drop the t-case in the first place?

I'd guess you may have problems with 2". I've seen an inch from time to time.

Watch the firewall/dizzy clearance.

I dropped mine an inch without any problems.

I went 2 inches and i had bad vibration issues like it was putting pressure on something that shouldnt have pressure on it.

X2!

Do remember when ya drop the t-case, it points the rear output down, potentially helping rear driveshaft angle BUT, it points the front output up, making that angle worse!

The limiting factors are distributor-firewall clearance and front driveshaft angle, as stated above.

I used to have about 1.25" of drop there without any problems. I fixed it since then, though.

CV shaft is better...

Remember too that the back of your t-case is right around your break-over point. You drop it down, there's a higher chance of smashing it on a rock.

Well I am not worried about rocks.. I have 14" of lift and currently 38" tires..

I did have 1" drop on my blazer previously with no issues aswell..

My drive shaft angles suck as it is.. Im trying to help the rear angle out..

for my front drive shaft, I am going to cut away a peice of the cross member for clearance and then weld in a support.. (my driveshaft hits the crossmember currently)

I was more concerned about distibutor cleance and angle of the motor mounts.

i could be wrong but i think ive seen a couple guys space the front driveshaft out basically like a wheel spacer.

I currently have some huge (7/8") nuts between the frame and crossmember and that took out some of my rear DL vibration. they make servicing the T-case easier than the addition of square tube or anything else I could come up with. Also leaves me the option of easy removal if some unwanted effects show up. If you go this route suggest grade 8 bolts replacement.

 

[RIPPEDK5]

Well I need more than just 7/8" nuts between my cross member and frame ( i have more lift that most normal people)...

I have thought about the spacer idea before--its not bad but driveshaft shops around here twinge at the thought and try to wack your for a new driveshaft.... (which i have one already)
