Hi Curt!

We have two Timbren options for your 2024 Chevy Silverado 2500 with 4 wheel drive and I have them listed below:

Timbren Suspension Enhancement System - Severe Service - Overall kit height: 5-9/16” - 8,000 lbs # TGMRTT35D
Timbren Rear Suspension Enhancement System - Overall kit height: 6-1/4” - 8,600 lbs # TGMRCK25D

The main differences between them is the overall height and capacity. Even with the # TGMRTT35D being slightly smaller and lower capacity, it would be the stiffer of the two, so I think you will be happier with the # TGMRCK25D that I see you went with.

Out of curiosity, what are you going to be loading in your bed? And will it always be loaded? These can be pretty harsh in unloaded trucks.
