Expert Reply:

The Timbren rear axle jounce spring kit you referenced, part # TDR1500DQ, is a fit for your 2013 Ram 1500 Quad Cab. This rear axle kit fits both 2WD and 4WD models.

There are several types of rear axle kits available for your Ram 1500. These include rubber jounce springs like the Timbrens, air bag kits from AirLift and Firestone, and coil springs such as the SuperSprings Sumo urethane coil helper springs. The link provided will take you to our page showing all of these products. The nature of your cargo/towing needs may help you determine which will best meet your needs.

Rubber jounce springs and urethane coil helper springs are cost-effective, easy to install and maintenance free. They typically only affect ride quality when the truck is under load; for normal driving you will not notice their presence. Air bags are more costly, have a more involved installation and maintenance requirements but offer adjust-ability to suit varying cargo and trailer loads. If you haul a wide range of cargo loads, particularly uneven loads, or tow a number of different trailers then the flexibility offered by air bags may be appropriate. The two linked articles will provide useful background on both Timbren and Firestone kits.

The most cost-effective and easy-to-install option is the SumoSprings Custom Helper Spring Kit # CSS-1168R. These provide progressive resistance as the load on them increases to provide additional support to your rear coil springs and help prevent body roll. These insert between the turns of your coils springs and are secured with simple zip ties. They require zero maintenance.

Please note that no suspension enhancement kit will increase your vehicle weight capacity; and all are intended for use with stock suspension systems that are in good working order.
