Going off-road with your Jeep Wrangler
If you own a Jeep Wrangler Rubicon, you don’t need me to convince you that it’s one of the best off-road vehicles on the market today. Here’s why:
- Capable 4-wheel drive system
- Excellent ground clearance
- Powerful transfer case
- Low gear range
- Towing capacity of up to 3,500 lbs
- Reliable water fording
- Four-link suspensions
The springs used on the four-link suspension mentioned above are linear coil springs. Also known as constant rate springs, these are the type of coil springs that most Jeeps come equipped with from the factory. Featuring evenly spaced coils for a uniform rate of compression, the spring compresses an amount proportional to the load being placed on the spring.
Even though the four-link coil spring rear suspension has a towing capacity of 3,500 lbs, the rear coil suspension on the Jeep Wrangler has its limitations. Believe it or not, the weight of a trailer will make it sag in the rear. When this happens, the weight of the vehicle shifts backward reducing the amount of traction on the front tires which will impact steering ability.
At the end of the day, too much weight on the rear suspension can cause sag and squat resulting in instability. As you’ve probably guessed, instability is dangerous and will require the driver to slow down to a crawl.
How to upgrade your Jeep Wrangler suspension
If you’re planning to take your Jeep Wrangler on an overland camping adventure, there’s a way to turn it into an off-road towing beast. A set of Timbren SES helper springs are designed to increase the spring capacity to prevent suspension sag and squat. The reason Timbren SES rubber spring upgrades are so effective is due to their progressive spring rate.
Timbren SES upgrade – part # JRJK – installs easily on your Jeep Wrangler. Just follow the 6 simple steps listed below:
- Raise vehicle allowing the axle to hang freely.
- Remove existing bump stop by prying out of bump stop cup.
- Use soapy water and position Aeon spring assembly into bump stop cup. Push and twist simultaneously.
- Ensure Timbren assembly is properly seated in bump stop cup.
- To ensure that the Aeon assembly is properly seated in the cup, it will help to place a temporary spacer such as a short piece of 2x4 wood between the axle and the Aeon assembly.
- Lower vehicle.
Timbren helper springs review
Over the years, Timbren SES suspension upgrades have been given many different names: Timbrens, rubber bumpers, rubber bump stops - or simply “them thar rubber deals.”
If you’re looking for rubber bump stops, we’re pretty sure you’re looking for the Timbren Suspension Enhancement System (SES). One of the reasons they’ve been called rubber bump stops is because they’re made of natural rubber, and they replace the factory bump stops. But Timbren SES suspension upgrades are a long way from ordinary bump stops.
In 1968, Timbren Industries introduced Aeon® rubber springs to the North American market. These rubber springs became the heart of all SES suspension upgrade kits. Because they’re made of natural rubber, they provide some unique advantages that other springs do not:
Metal springs have a linear spring rate: In other words, a metal spring has the same spring rate as it compresses all the way down until it bottoms out. One of the unique characteristics of a hollow rubber spring is its progressive spring rate, the ability to self-adjust. As the load increases, so does the spring rate.
Hollow rubber springs possess a unique quality called “hysteresis.” Simply put, they act like a shock absorber, able to absorb the kinetic energy every time the suspension deflects.
Because of these 2 unique advantages, Timbren has always maintained that their Aeon® hollow rubber springs are “Stronger than steel, more reliable than air.” For this reason, Timbren SES helper springs – part # JRJK – have become one of the most popular suspension upgrades for the Jeep Wrangler.
At the end of the day, Timbren SES suspension upgrades give you the biggest bang for your buck. Check out the benefits you receive when you install an SES upgrade:
Timbren SES helper springs are a DIY solution that can be installed in your driveway using tools you have lying around the house. You can go from install-to-haul in about thirty minutes.
Timbren SES upgrades are the best choice because they’re the most reliable. Like we said earlier, Timbren SES upgrades offer a progressive spring rate and require zero maintenance. These 2 advantages alone guarantee for you the most reliable helper spring in the industry.
And each kit comes with a Lifetime Warranty and a 100-Day Money Back Guarantee. Head on over to Timbren.com and transform the way your SUV tows and hauls right now.
