Man,,,, i'm pretty bummed out over the 14'' wheel limits. I've already sourced the jeep and the astro-shaft i had no idea the astro shaft wouldn't work on the 78'. I've also heard that the g-body tie rods will 'rub' the boots with the blazer spindle and brakes which i have already sourced as well. And I thought i read on here that the tall lower ball-joints will work but the tall uppers will not with the smaller wheels. humm???
The only thing tall lower balljoints do is lower the car. Tall UPPER balljoints help the camber curve and make it handle better. Stop worrying about the balljoints and only get the tall uppers. Seap the steering column for a 79-later model and use the Astro shaft. It's worth it....
The .5" taller lower ball joints further improve the camber curves and roll center location, significantly reducing lateral roll center migration for more predictable behavior. They also correct the factory bump steer issues by raising the tie rod ends into proper alignment.
To achieve zero bump the front end must be designed correctly. The tie rod must travel on the same arc as the lower control arm when the car goes through travel. The stock G-Body does not do this!
Ok, I actually agree. Now how is he going to run tall upper AND lower balljoints, all while using 14" wheels AND keeping stock ride height? I'll wait....
Yes will lose 1/2" of front ride height. If he wants it back he can simply use a 1/4" shim under the front spring. Here is a 14x7 with 3.5" BS on our Pro Series Stage 2 Front End( tall upper and lower BJ). No interference issues. Have a great day guys! View attachment 99618View attachment 99619
