Q: I installed a rear kit on my pickup truck and it’s almost touching the axle. The installation instructions indicate that I need a 1 inch gap. What should I do?
Remove the rubber spacer supplied in the assembly. If you have already done this or if there is no spacer in the kit then take the vehicle out for a test drive. Often with a vehicle having a partial load, or a vehicle having an older suspension, the rubber spring may be in contact with the axle with no adverse ride quality. If ride quality is poor, contact Customer Service.
Q: I installed a rear kit on my pickup truck and there is more than 3 inches of gap between the rubber spring and the axle. Is this ok?
Ideally, you want to adjust the rubber spring assembly to a gap of about 1 inch. In most cases this can be done with a spacer included in the kit. If you have already installed everything included with the kit, and you still have too much gap, contact Customer Service.
Q: The capacity rating of the ses kit seems awfully high. I am sure that I do not need that much capacity for my application. What do you recommend?
The real question you seem to be asking is ‘Will this give me a rough ride?” The product’s progressive spring rate provides superb ride quality with any load. Also – when cornering, swerving or in high wind situations, the improved stability offers great performance and peace of mind.
A. If you have installed the Timbren SES (Suspension Enhancement System) and find that the vehicle ride quality is poor when empty, measure the gap between the rubber spring and the axle. (See Question and Answer #1 for further details and solutions.)
Not at all. Primarily, the total weight of the vehicle normally contacts the axle at a point under the leaf springs. The rubber spring, however, contacts the axle at a secondary point of contact. By adding a secondary point of contact we are reducing the stress at the original point and are spreading out the load to 4 points of contact on the axles instead of 2.
Furthermore, the progressive spring rate provides a soft uptake of the load rather than the sudden stop of a solid bump stop, providing a good ride with reduced stress.
Q: I have a 1985 motorhome with a badly sagging rear suspension. Will Timbren’s SES (suspension enhancement system) help?
A. Timbren’s Suspension Enhancement System will certainly help, but our systems are designed to work in conjunction with a suspension that is in good condition. We recommend that the motorhome be inspected by a suspension specialist, to ensure the suspension is in good condition, prior to installing a Timbren system.
A. You cannot exceed the manufacturer’s axle rating or GVW rating of the vehicle. A Timbren suspension enhancement system will greatly enhance the performance of a heavily-loaded vehicle by adding to the spring rate. You can expect reduced sag, and improved roll stability.
Here are 7 ways to compare Timbren’s SES to an Air Ride system:
- Ride Quality: SES upgrades deliver a softer ride empty and loaded – especially with extra-heavy loads
- Stability: SES upgrades eliminate roll and sway – even with the heaviest loads
- Reliability: SES upgrades are made to last – they will never start leaking air because there is no compressed air.
- Ease of use: SES upgrades require zero maintenance.
- Ease of installation: SES upgrades take less than an hour to install
- Price: The installed price of an SES upgrade is about 1/2 the installed price of an air system
Warranty: SES upgrades come with two of the best warranties in the industry
- Lifetime warranty
- Customer Satisfaction Guarantee
