Stiffer rear coil springs

[rtm03862iq]

I have a 2023 Tahoe SSV (police fleet model) and the stock suspension, especially the rear, is a bit soft. Does anyone make a replacement coil spring which will maybe stiffen up the rear a bit? If so, does anyone have any reccomendations?

Thanks
Ryan

I suggest that you contact Summit Racing or Texas Speed and discuss your desire with them. They are specialists in mod equipment, and would be able to give you sound advice on alternate springs.

Took 'em long enough to do something... Though I guess it was pointless, as 2 dealers including my gold standard dealer didn't find the TSB.

Has anyone gotten a set?
