FREQUENTLY ASKED QUESTIONS

The amount of time will vary with the kit you are installing and the equipment you have. Typical installation at a home garage with tongue jacks and a socket wrench will take about an hour. If you are service facility and have pits or lifts, the install process can sometimes be done in as little as 15 minutes.

Yes, everything is included except the tools - for most applications all that is needed is a wrench and a screwdriver. The kits include all the necessary hardware, the 2 Timbren springs and instructions.

They are hollow rubber springs that do not require any air. Air spring kits will require an air compressor kit or some type of inflation device. These require no air and once you install them they require no attention or maintenance.

This will depend on the vehicle you are installing the kits on. Both replace the factory bump stops, so the install process will be similar. SumoSprings have applications that are always in contact, so the install may include top and bottom brackets. We recommend reviewing the instructions for each kit for comparison. Overall, both are a simple installation that can be done at home.

This is commonly caused by too small of a gap from the bottom of the spring to the axle. Timbren bases this gap from the top of your axle to the bottom of the rubber spring using a suspension that is in good condition. If you have a suspension that is showing some signs of fatigue, this can reduce the size of the gap. Ideally for rear kits you should have a 1 inch gap for light duty pickup trucks, and SUV’s. 1 ton trucks typically have a ½ inch gap and heavy duty applications are always in contact. If you have a ¼ inch gap the spring will come into contact when hitting a large bump or pothole causing a rough ride. This can be corrected by removing the spacer that comes with the kit to increase the size of the gap.

We see this more often on older trucks that have a weakened leaf springs or other components of the suspension. If your springs are worn out, we recommend replacement leaf springs before installing a Timbren SES kit. Constant contact will not harm anything as the Aeon springs are progressive. They will help support the extra weight of the load and take some of it off your existing suspension and disperse it to the axle. It will not harm the axle. If you were hitting your bump stops before and now you have full time contact with your Timbren springs, you are much better off. The jarring caused by hitting your factory bump stops can cause damage to your suspension. It will not cause problems if you are constantly riding on your Timbren springs.
