Spacers Needed For Timbren Springs # TGMRCK25D On Lifted 2020 Chevy Silverado 2500HD

Question

Question:

Good morning, I’m thinking of going with the timbrens on my 2020 Chevy Silverado LTZ 2500, 4 wheel drive, crew cab. I’m guessing the truck has been lifted by previous owner, I have a measurement of 9 1/4 inches from the top of original bump stop to axel,any help as to what I may need is greatly appreciated thanks.

With the Timbren Rear Suspension Enhancement System # TGMRCK25D being 6-1/4" overall height and Timbren recommending a 1/2" to 1-1/2" gap it does sound like you have a 2" lift on the rear of your 2020 Chevrolet Silverado 2500 LTZ.

Timbren does offer a 1" Spacer # A25723-90AH00 and 1/2" Spacer # TA25722-90P00 that can be used to get the Timbren springs to the correct height you are looking for on your Silverado.
