Does anyone have the amount they had to shorten the driveshaft on their lowered 4x4 RCSB? Trying to get one ordered before I start installing parts. TIA

Shouldn't that be in the instructions or on the kit manufacturer's website. It should also be based on year model and how much you are lowering.

I haven't seen the instructions, but if anything they would tell you to check it. I doubt they will give dimensions, like you said with all the different cab configurations and heights. Trying to find someone that has done one of the 3/5.5 kits on a RCSB 4x4 to see if they have the length.

I haven't really read anyone talking about making 1 longer or shorter which suprises me cause it sure makes sense to me that you would need to

I read through some of the older posts where guy's with my truck shortened them, but no one is responding with how much. It's definitely something people need to check, you don't want the driveshaft jamming into the back of the trans.

I thought same cause I'm fixing to lower mine and will measure the travel when I do it and I'll have it shortened if nesessary .I read a lot and always thought aren't you driving the shaft in and reducing travel

TriSum

Yes, you are. I just don't know how much. I guess I'll figure it out once I get started.

With a 5.5" drop on the rear, you're probably using a flip kit, I would assume. On the Mcgauhy's kit that I installed, the new perches that cradle the rear end have offset holes to allow the rear end to slide back perhaps 3/4" inch form the original position, making shortening the drive shaft unnecessary....at least in my case. Mine is 2wd however, and I have a two piece drive shaft.
Which kit are you planning to use? A lot of the kits have instructions posted in a pdf file that can be downloaded and read before even purchasing the kit.

Looking at the 1000HK Belltech kit. The RCSB 4x4 has a lot less variance for driveshaft length, being so short. I guess I'll see once I get there. Thanks for your input.
