Installing a Timbren kit on a 2012 Ford F-150

Installing a Timbren Kit on a 2012 Ford F-150 is simple to do and only requires a few basic tools. Timbren offers 2 different kits for the rear of a 2012 Ford F-150. For this Timbren application the customer tows a horse trailer and frequently hauls heavy loads. We decided to go with the heavier Timbren kit FRTT1502D. Timbren Kit FRTT1502D fits 2009-2012 Ford F150's, both 2 or 4 wheel drive. The kit has a 7,000 lb maximum rating, which is more than enough for a F-150.

Below is a summary of what is involved for this 2012 F150 Timbren install.

  1. Raise your 2012 Ford F-150 allowing the axle to hang freely.
  2. Remove your existing bumpstop using a 13 mm socket.
  3. Assemble Timbren rubber spring and bracket
  4. Mount the Timbren spring using the existing holes in the frame with supplied fasteners.
  5. Lower vehicle and your good to go!

The rubber Timbren spring for a 2012 F-150 is desinged to sit about an inch above the axle as you can see in the picture below. This allows the suspension to work as desinged from the factory without assistance from the Timbren kit. (The flaking on the spring is normal and will come off after a few car washes)

Timbren Kit

We connected the customers horse trailer to test out the install. As you can see the spring is now in contact with the axle, but is hardly compressed. The Timbren spring is hollow on the inside which allows it to have some 'give' and expand and contract with varing load conditions. When the horse trailer is loaded with horses the spring will compress and help support the tongue weight of the trailer and prevent the 2012 F-150 from sagging.

As you can see the 2012 Ford F-150 sits level and is ready for the road.

Timbren Review: Ford F-550 Super Duty

Timbren KitEven super duty vehicles need some help with their suspension when hauling a heavy equipment trailer or other loads. A heavy haul can cause costly damage to even the toughest work truck’s suspension. A Timbren Leveling kit is a cheap and easily installable solution to expensive and dangerous problems down the road.

Ford Truck Timbren Kit

A 2010 Ford F-550 Super Duty was recently brought to us for this very reason. This truck has been in use for hauling heavy equipment with a trailer. Even with its heavy duty suspension, it was in need of some extra leveling support to reduce the amount of roll and sway experienced while driving. The Timbren FRSDD Bump Stop was installed as an answer to this issue.

Once the Timbren FRSDD helper springs were installed, there was an immediately noticeable difference. The OEM bump stops, while of a heavy duty quality, could not compare the new helper spring. By adding the Timbren spring, we had removed the several inches of slack that had existed between the leaf spring and the OEM bump stop. As a result the Timbren Kit provides cushioning and support to the suspension at all times, as opposed to the OEM Bump stop which only will provide relief when the spring is about to bottom out. By avoiding this shock to the leaf spring, years can be added to your truck’s suspension.

Ford Truck Timbren Kit

The FRSDD Rear Timbren Kit fits:

  • 2007 – 2011 F-450 Super Duty Cab & Chassis
  • 2007 – 2009 F-550 Super Duty
  • 2007 – 2011 F-550 Super Duty Cab & Chassis

Product Installation: Rear Timbren Kit

Timbren Kit Memorial Day has come and gone, that means summer has finally arrived. This is the time to get those campers, boats and trailers out of storage and back on the road. Unfortunately, this means added wear and tear on your pick-up truck’s suspension.

Have you been noticing that extra strain on your truck suspension lately? Are you bottoming out your leaf springs every time you pull your trailer? Is there a noticeable sway in your ride when you pull your boat? Does pulling that huge camper make you nervous around turns? If this is the case, your problems can be solved by adding a Timbren Suspension Enhancement System to your truck’s rear suspension.

Chevy Truck Timbren KitWe recently installed the Timbren GMRCK15S Rear Bump Stop in a 2002 GMC Sierra 4x4. The owner of this truck had been towing a 21 foot 5th wheel trailer and had noticed that his leaf springs were bottoming out. Concerned that the shock would damage his vehicle, he brought it to our truck suspension experts. Adding a Timbren kit to his vehicle’s suspension system was our answer.

Timbren Kit

Upon inspection of the Sierra, we found evidence of trouble already brewing. We noticed that his pre-existing bump stops were grossly inadequate for the load he was carrying. These bump stops were literally rotting off of their mounting brackets and took only a slight amount of pressure to snap them off completely.

Timbren Kit

Timbren kits are a popular addition to a truck’s suspension for several reasons. Adding a Timbren kit can go a long way to improve the quality of your vehicle’s ride by increasing the stability of your leaf springs. By decreasing the leaf springs’ range of movement, the Timbren helper spring cushions the impact on your suspension system, resulting in more road shock being absorbed by your suspension and less shock absorbed by you. Further, by replacing the pre-existing OEM bump stop, the Timbren kit protects your vehicle from the damaging effects of overloading. This protection increases the life of your vehicle and its suspension system.

The GMRCK15S fits 1999 – 2011 GMC Sierra 1500 and Chevrolet Silverado 1500, two wheel and four wheel vehicles. This kit will fit regular or 3 door models but it will not fit XFE models.

A heavy rear load, such as a 5th wheel trailer, can really abuse your truck’s leaf springs causing them to sag and even become damaged. With an 8,600 lbs. capacity the Timbren rear suspension kit protects your truck springs from damage caused by bottoming out on bumps my acting as a bump stop and restricting the range of motion available to the spring.

While taking a turn, the weight of your vehicle shifts, moving the center of gravity away from the center of the vehicle. The farther it moves from the center of the vehicle, the less stable the vehicle becomes. The rubber helper springs help to distribute weight evenly to all tires. This even distribution makes steering easier, decreases wear and tear on your breaks and tires.
