Rear Bump Stops: Why Rear Bumpstops Are The Unsung Heroes of Suspension Systems

The automotive industry places a lot of attention to shock absorbers, leaf springs, and lift kits when giving out their recommendations for suspension upgrades. But very little is said about the lowly bump stop. 

What are Timbren rubber bumpstops?

Timbren bumpstops - aka Timbren SES - replace the original bumpstops on your tow vehicle. For this reason, many folks confuse them with bumpstops. But Timbren SES upgrades do far more for your tow vehicle than any ordinary set of bumpstops. That’s because of the Aeon® hollow rubber springs that are included with every single SES upgrade.

In fact we really can’t reference Timbren rubber bumpstops without talking about patented Aeon® hollow rubber springs.

Timbren SES upgrades are a set-it-and-forget-it solution that safely and effectively keeps your vehicle level under the heavy load of a large trailer or a load of gravel in the bed of your truck. Once it’s installed, an SES kit works to keep your vehicle level and stable even under the heaviest loads.

The secret sauce of an Aeon® rubber spring is its progressive spring rate. What is a progressive spring rate?

Metal springs have a linear spring rate. In other words, the spring rate (e.g. 300 lbs for every inch of deflection) remains the same all the way down to total deflection. On the other hand, a progressive spring rate continually increases as the load increases. This guarantees that your truck remains level and stable at all times.

Timbren SES suspension upgrades give you the biggest bang for your buck when it comes to keeping the truck stable. Here are the benefits you receive when you install an SES upgrade:

• Affordable - most Timbren kits are less than $300.00

• Easy to install - most Timbren kits take less than 30 minutes to install

• Absorbs road shock - Timbren SES kits improve the ride quality even with the heaviest loads

• Levels out the trailer - Timbren SES kits keep the tow vehicle from squat

• Zero maintenance - just set it and forget it

• Prevents roll and sway - Timbren SES kits help to stabilize the load

• Help maintain control - improves steering and braking

There are over 400 Timbren SES kits that fit virtually every truck, van, and SUV that rolls off the assembly line. Every component is carefully selected to provide the best combination for your vehicle’s suspension.

Why are rear bumpstops so important?

Timbren SES rear bumpstops make the difference between sag and squat and complete stability. Without Timbren SES suspension upgrades, your truck’s rear end is going to sag when you hook up your trailer. Towing a trailer is risky business even at the best of time. But when your suspension is drooping while you’re pulling a trailer, you are putting yourself in harm’s way.

When your truck’s rear end is sagging, the front end is too high. This negatively impacts your steering and braking. And I don’t need to explain how dangerous it gets when you’re towing a large trailer, right? That’s how accidents happen at high speeds!

The best shock absorbers money can buy aren’t going to fix the problem of sag and squat. Adding more leaves to your suspension will stiffen the ride, but it isn’t going to increase stability. Timbren’s SES hollow rubber bumpstops are the ticket to increased safety and stability.

How do Timbren SES bumpstops protect your suspension?

We talked briefly about Aeon® rubber springs, and how their progressive spring rate allows these SES ‘bumpstops’ to eliminate sag and squat. Well, Aeon® springs have another innate characteristic, something called ‘hysteresis’.

Hysteresis is a fancy word for shock-absorption. Aeon® rubber springs are able to absorb road shock and smooth out the ride and prevent bottoming out. Road shock and bottoming-out can do a number on your suspension by causing the leaf springs to over deflect. By smoothing out the ride, Timbren SES bumpstops protect your suspension and preserve the life span of all your suspension’s components.

What are the unsung benefits of Timbren SES bumpstops?

We’ve talked about the significance of “progressive spring rate” and “hysteresis.” Below is a list of some of the benefits you get when you install a Timbren SES upgrade:

Easy installation:  If you know how to remove a bump stop, you can install an SES kit. Some are so easy, all you do is pry the bump stop out of its cup and replace it by popping the Aeon spring up into the same cup.

Zero maintenance: Unlike air spring helpers, SES upgrades do not require any upkeep. If you purchased the appropriate kit for your vehicle, the rubber springs last the life of your vehicle.

Load leveling:  It doesn’t take much to cause today’s pickups to squat. Timbren SES upgrades are designed to keep your vehicle level even under the heaviest loads.

Increased stability:  A truck that doesn’t sit level has problems with stability. Not only do Timbren upgrades level the load, they reduce roll and sway for loaded vehicles.

No B.S. Lifetime warranty: Every Timbren SES kit comes with a lifetime warranty for as long as you own the vehicle.

100-Day Money Back Guarantee:  Here’s the kicker… If you are not completely satisfied with your purchase, your money will be cheerfully refunded.

These easy-to-install rear bumpstops from Timbren are a DIY system that require common tools you already have in your toolkit. Just another way Timbren SES upgrades save you money.
