Review on 🚗 Timbren GMRCK15S Suspension Enhancement System: Boost Your Vehicle's Performance by Jeff Keegan

Received these today and installed them in about 30 minutes. Most of the time was spent lifting each side of the truck. I would say it was a very easy setup. I took it for a test drive and on smooth and mostly flat roads, the ride quality didn't deteriorate; However, the second time I hit a speed bump or a deeper gully or something, you could tell the difference - they hit hard (as expected). A few times a year I tow a 33ft/7500lb trailer (fully loaded) and this year also bought a 2020 GMC Sierra 1500 SLT with the Max Trailering (nht) package. This truck has enough power for the trailer and all the gear, but for some reason - even after fine-tuning the new WDH brand dock leveler - it squats a bit with a full trailer load (no squats with an empty trailer). I've taken all the weights and am well within all the load limits (payload, max nose weight, GVWR, GCVWR, max trailer weight, etc.). I hope these timbres solve this problem. I'll find out in a few days as we're going somewhere again this weekend. Fingers crossed!
