99-06 1500 IFS Upgrades
#11
My rear Tahoe links are uniball/heim at the axle side and bushed on the frame side. My Ranger midtravel kit that I am also DIY'ing is all heim and uniball front, bushed on the leafs in the rear
Heims and uni's are a little noisy when dirty, but they are tough SOBs and can take a ton of abuse. BJ's typically are a much smaller bearing surface and wear out much faster. Regardless of the amount of grease or type of grease you squirt in there, they just can't handle the load from a load spreading/dynamic distribution perspective
Since 1500 GM's have arguably the weakest IFS components in the history of IFS, I am looking to see what options are out there to beef up our front ends

The heims also wore out quick on me. Probably my fault. Now a lot of companies use Roto-Joint or Del Spheres. I haven't used any yet but in theory they sound like a nice compromise between rigidity and harshness. https://www.spohn.net/delsphere/

There are a lot of companies (EMF EVO Joints, Enduro Joint, Johnny Joint) that all promise the rigidity of a heim, without the hassle of a heim
The worst part about uniballs and heims is the design that incorporates them has to be perfect. Since the joint only moves in a sphere, and cant deflect in all axis like a bushing can
Everything is a system of compromise, just have to find what you're willing to compromise- if you're willing to step out of the OE bounds

You just said upgrades for IFS. You didn't give specifics haha.

With my little metric 33s I get ~30k out of a front end, and I am far from the "hardest" on my truck. I know there are ppl out there looking to not have to do a front end every 30k, but also not wanting to jump into the SAS route. I have the skills and tools and knowledge and funding and even the axle and wheels (read, not time) to SAS my rig and that is my plan, but not everyone has that luxury

Not my truck
I am SAS'ing my truck. No doubt about it
But I sure am interested in ancillary income. That's the best way to get anything done- pay for it
I've got nothing but time at $100+/hr ahaha

Potential business venture to offer front end upgrades to folks with 99-06 1500 trucks who want to run 33's and cranked keys/leveled but don't want to spend $2500 with JD Fab or Cognito. My intent would be to offer uniball uppers, with bushings on the frame side at about 50% what the "other" guys are charging

OEM as in, what the truck rolled off the assembly line with

You must be "1 in a million"
If I do it again, this will be the 3rd "problem solver" front end Ive put on my Tahoe, and I'm not even mean to her. Part of reason for the SAS, plus I can move the axle forward, run 35s without rubbing and generally just be bad ***
I can't be the only knucklehead tearing up front ends out there. Plus, there is a lot of travel in our front ends if the UCA BJ wasnt stopping droop and that damn "down travel" limiter on the frame was cut off

I killed several sets of uppers in my RCSB and the Tahoe was floppy As can be when I bought it but, I’m known to be rough.
With the JD arms and coil overs it has enough droop to pull the cvs out of socket. In fact, every time I jack the front end up they pop out and I have to lower it and turn the wheels back and forth to get them to pop back in. #needslimitstraps
