Is there a general consensus on what setting is needed on this shock to fit 275/60/20's? Those of you that have installed the the 5100 Ride Height Adjustables on your GMT 900's..What height are you set at and what size tires are you running? The 5100 ride height adjustable shocks allow for stock ride height, .59 inch lift, 1.19 inch lift, and 1.77 inch lift on our GMT 900's. I would like to be able to fit 275/60/20's on stock wheels with raising the front as little as possible and was wondering what setups everyone is running with these shocks? Thanks!

I would say the 1.77

 

 

What's the measurement at the wheel well with your shocks set in that position and are they maxed out on that setting?

Looking to get adjustable shocks soon.

If it helps any......I put mine on the top setting of 1.77 and it raised the front end exactly 1 3/4 inches measured from the ground, by the centerline of the wheel to the fender lip. I'm just running the stock 265/70-17's right now, but gonna step up to 285/70-17's when I wear these tires out.

Thanks, exactly what I wanted to know.

What do you guys think about using these shocks on the "0" setting and using the RC spacer for the lift? My thought, I could be wrong, compressing the spring more by using the 1.77 lift will result in a stiffer/harsher ride. Thoughts?

Going with the HD shocks would probably be a better cost saver, without sacrificing the ride if you wanted to go with the spacer as well??? Does maxing out the height adjuster shorten the durability of the shock?

Since the spring compresses 2"-3" with the weight of the truck, moving the bottom spring seat up on the shock body does not change the spring preload as much as some people think. It does result in sightly less down travel, but that is usually not an issue for a daily driver. If the truck did not compress the spring under it's own weight, then chaning the position of the bottom spring seat would have an impact on ride quaility.

 

If you measure the compressed length of the coil spring in stock form, and then compared it to the compressed length of the coil spring on the bilstein shock at its highest setting, the measurements will be the same. This preload adjustment is irrelevant due to suspension sag when the vehicle weight is applied.

 

As long as the suspension is not topping out when the tire drops off in a pothole, then ride quailty should remain acceptable no matter what position you set the 5100 at.

Thank you for the explanation. The above quote is the exact reason for me wanting to change to the Bilsteins. I am almost thinking though that it might be financially better to get a rough country leveling kit with the Bilstein HD's?????

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      OCI, not when but why?

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.

      Engine Wear and ISO 4406   1.) Cold Starts. 2.) High Particle Count. 3.) Low operating temperature viscosity and high low temperature cranking viscosity. 4.) Depleted AW, Friction and Acid packages.  5.) High engine load.    https://me.caltexlubricants.com/en_me/home/learning/from-chevron/heavy-duty-diesel-vehicles-and-equipment/The-Importance-of-Clean-Engine-Oil-and-Its-Impact-on-Equipment-and-Business-Performance.html   High particle counts have five sources. 1.) They are manufactured within the engine. Both wear debris and amalgamation of degradation products and combustion driven soot (worse in GDI). 2.) They are ingested via intake air. Ever hear the best oil filter is a good air filter? 3.) They are entrained in the fuel. 4.) This one is insidious. They are introduced in 'fresh oil'. 5.) They are introduced during the oil change.   ISO 4406 is the test that measures and quantifies the combine effects of all of the above particle related issues. You can mitigate your way into multiples of engine life by being attentive to them all.    https://www.hyprofiltration.com/blog/is-new-oil-clean   (from the link above)    [Quote] What Is the Recommended ISO 4406 Cleanliness Code for New Oil?   A good upper limit for new oil cleanliness is 16/14/11 (ISO 4406). Typical new oil usually has ISO codes of 19/17/15 or worse, which is far too dirty for sensitive components. This can be a major cause of degradation and premature failure.
