Well, their primary function is to be part of the suspension, working in conjunction with the torsion bar and the shock absorber to control how the wheel moves up and down relative to the frame. It also acts as a bump stop for when the truck lands after a jump.


It is not "sloppy assembly", as it is designed to assembled this way, that the jounce [proper term for it, not bump stop] is just touching the LCA.

===========================================


Interesting - if what you say is correct, GMC/Chevrolet torsion bar suspensions were designed for the weight of the truck to "sit" on these "jounce" biscuits, effectively eliminating any significant upward movement of the wheel when it hits an un-even surface?


If what you say is true, how come GMC/Chevrolet advertising suggests these vehicles need not be limited to absolutely smooth perfectly maintained paved roads ?


Now that I have somewhere between 1/8 and 1/4 in. clearance between the lower inner control arm and the "jounce biscuit", my front wheels are able to move up and down several inches, meaning the front suspension is now operational.


Big improvement over uneven road surfaces. Instead of every uneven portion of a road ( or off-road) ...being slammed directly into the truck's frame from a non-working suspension....I now have a smooth controlled ride.


I think we will have to agree to disagree. Now, again, I am not making fun of those who want a noisy hard riding truck. There are many reasons for that. Just not my thing.

Well, you should definitely phone up GM and tell them they are manufacturing all their trucks wrong. They probably will also offer you a six-figure job to fix the problem since you know how to fix it, and they don't even know they have a problem.

Any truck that runs a snow plow especially A GM IFS should have a set of Timbren springs. Inexpensive and will only help everything.

Old truck or new truck this is sound advice.

Yes , on IFS trucks they replace the OEM jounce bumper.

I have not looked specifically for you model truck but I would think yes.
