Hello Christopher. We do indeed have Timbren SES for the 2009 GMC Sierra 1500. For that you will need the Timbren Rear Suspension Enhancement System # TGMRCK15S. These are rated for 8,600 lbs and are confirmed to fit the 2009 GMC 1500 as long as your vehicle does not have the XFE package. view full answer...
Hey Charles,
For your 2012 Chevy Colorado, I 100% recommend going with the SumoSprings Solo Custom Helper Springs # SSR-210-40.
The Timbren # TGMRCC will work, but they can make your ride very rough, especially when unloaded. The SumoSprings are going to give you more than enough support for when you are towing your boat and/or have gear in your Colorado's truck bed.
So the SumoSprings # SSR-210-40 will give you the benefit of stability and helping with sag while not giving you a ride... view full answer...
