I have a 2017 Four Wheel Drive Sierra with the Max Trailering Package and the 6.2L engine. I tow a 34' Airstream travel trailer (9,000 pounds loaded and about 1,000 pound tongue weight) and I get a good deal of porpoising on some washboard type roads. I have a Hensley Arrow Equalizer hitch with 1,000 pound spring bars. Also, I consider the truck under damped even when I'm not towing. I'm considering upgrading to the Bilstein 4600 series shocks F & R. Does anyone have a similar experience with this situation or the Bilstein 4600 shocks. I installed these shocks on my 1992 Suburban many years ago and I was very happy with the results.
Towing shocks bilstein 5100 vs 4600
calgator73 posted a topic in 2014-2018 Silverado & Sierra ModsSpoke to NC sales today regarding availability and was told that the rear 5100s are out and the front shock part numbers should be available just before SEMA in November. I asked the differences between the 13 and 14 since people are putting the older part# on the 14s. He stated that the new design has an integrated bump stop that the older version did not have. He wasn't sure about compression and rebound rates. I told him that I had installed supersprings on the rear axle to decrease the amount of porpoising (yes wdh is at full load restoration) caused by the various bumps on the interstate and that it mostly worked but my unloaded rear height was too high for my taste and that my intent was to add the 5100s to both increase my front height (restore original rake) and provide additional damping. He recommended that I use the 4600s instead of the 5100s and consider removing the springs. His claim is that when compared to the 4600s, the 5100s are designed to be easier to compress with about the same rebound damping. Thoughts?
New shocks, loud thump
Mark140 posted a topic in 2014 - 2019 Silverado & SierraAbout 600 miles ago I had Bilstein 4600's installed on all corners, as well as BFG K02's (275/55/20). When going over a speed bump the front driver side makes a loud thumping that can be heard and felt. Is it possible that the shocks were installed wrong or is the heavier tire making the suspension work harder?
Better Than New
Mark140 posted a topic in 2014 - 2019 Silverado & SierraJust got Bilstein 4600's and BFG KO2's (275/55R20) on all four corners. The Silverado rides and handles better than it did off the showroom floor and it only has 15,000 miles on it. Seriously, worth every penny. If it wasn't for y'all on this site I never would have gone in this direction. Thanks.
