Rear Suspension Enhancement for 2021 Chevy Colorado 4x4

Updated 02/22/2021 | Published 02/19/2021

Question:

Have 2021 Crew Cab ZR2 Diesel Colorado 4x4. Want a SUMO type product that will provide minimum sag in rear under load. Constant bed load of about 300#. Additional occasional tongue weight of no more than 400#. Distance between top of leaf pack and bottom of frame is 7-1/4. U bolt Center/Center dimension is 3-3/4. Thanks.

For your 2021 Chevy Colorado 4x4 we have the Timbren rear suspension kit part # TABSOSR as a confirmed fit that would do an excellent job reducing the sag you are experiencing. SumoSprings does not have a kit for your truck at this time but the Timbrens are essentially the same design as it's a jounce type bumper designed to replace the bump stop.
