Air Controlled Bed Stop Valve - No more cables to break. Adjust or tubes to get into chassis components.

Bed Light Connector Harness - We don't cut your wiring and void your warranty. It can easily be disconnected for diagnostics and repair.

We use one of the best dump pump brackets on the market - Not only on our new installs, but replacements as well.

We use hydraulic shut off valves on all our builds. Located at the supply tank.

Three line hydraulic system adds extended life to your system. It brings fresher, cooler oil into your pump. When you forget to disengage it, you get more time before you do major heat and abrasion damage.

Manifold block in the cab floor - Not just a hole in the floor. It keeps out dust, noise, heat and cold.

Hinged Lid Control Box - Has all the components in one easy service place. No more lying on a seat and removing cables, consoles, brackets and wiring in order to change one unrelated component.

All wiring and air lines are color coded for easy diagnostics and repair.

Air System Protection for the body- We protect you from sudden air drop with a valve between the OEM and our upfit. If our system fails the air shuts off at approximately 65 PSI.

A Manual shut off valve isolates our build from the OEM side for a quick diagnostics of air problems. Just close the valve, and you will know quickly the air problem. One way check valve. Air goes in and does not back feed.

We use the same control components in all our builds. We know what you need to make a repair without the hassle on what model, build you have. No more guessing on axle, bed or tarp control you need.

1. The competition image shows an electrical junction box that requires the cutting of the factory wiring harness. Cutting it voids the factory warranty on that harness. We at Palmer simply plug in our custom made adapter.
2. The wires have not been sealed at the entrance of the box and the box will fill with dirt & moisture over time. The Palmer adapter is self sealing.
3. The system can not be bypassed for diagnostics because the wiring has had the ends cut off when it was up-fit. If you want to isolate the Palmer build from the factory just remove the plastic ties and unplug our adapter, reconnect the factory ends. Everything is still there just as it came from the factory.
4. To add lights or a backup alarm you must remove the cover and remove a nut and washer from a post inside. The Palmer adapter has extra points to connect more accessories.

1. The first image shows a PTO with a left hand mounting configuration, this is easier to install but it places the pressure and inlet lines in front of air tanks and other obstacles mounted below the frame rail. We at Palmer use a much better designed PTO with a right hand configuration. This moves it to the center of the transmission to avoid most obstacles.
2. The hydraulic pump is clocked (installed) hanging down low. This makes it easy to bottom out when off road. Palmer mounts our Muncie hydraulic pumps rotated 180º, high under the transmission out of harms way. It also allows us to use a much shorter hydraulic pump support bracket to stop resonating vibration from today’s high torque engines.
3. The pump bracket just supports the weight of the pump at one point only. Palmer uses one of the most advanced brackets on the market. We felt something could be done to improve the life of the PTO & Hydraulic pump. After researching things we found that with today’s high torque engines we need a four point hydraulic pump mount to stop radial torque and high frequency vibration as in addition to the weight of the pump. The bracket Palmer uses is adjustable in all directions and never welded on so it can never bind the pump when installed.
4. The pump shown has only two lines, when it is engaged it circulates inside of the pump about one cup (8 oz) the same hydraulic oil for as long as you leave it engaged. Just sitting engaged at engine idle speed this heats the oil 1.7 degrees a minute. If you run down the road engaged the pump is destroyed in just minutes. Palmer uses a three line system that brings in fresh oil from your 25 to 30 gallon hydraulic tank any time the pump is engaged. This provides extra protection for your system.
5. Note the water pipe 45º elbow in the high pressure line of this install. This line will see pressures of 2000 to 2300 psi on a properly adjusted system. And can hit infinity if the operator lowers a loaded bed down at a high rate of speed then stops quickly, when this is done there is no place for the pressure spike to release its energy sometimes causing the weakest point to fail. In this build it would be the water pipe joint. Palmer uses HYDRAULIC fittings for everyone’s protection.
6. Note how the pump hoses are rubbing on the air tank even with the 45º elbow installed. Palmer avoids this issue by using our right hand PTO configuration.

What the competition does

The wiring and air lines are tied tight in one bundle. Palmer separates things out. Some things move with the engine and transmission, some with the air ride cab and need to be installed that way.

1. There is no grommet or padding on the sharp edge of the floor. The cover is ok for now but the line bundle has been tied tight to the transmission and the cab is on air-ride. Palmer uses a manifold block.
2. The pink insulation in the bottom of the box can be seen to keep out air and dirt. Palmer uses a manifold block

The bed stop cable has to be adjusted and maintained. And if misadjusted it can lead to the spool valve leaking. Palmer uses an air valve to stop the slave valve from raising the bed just before the mechanical limits of the hoist cylinder are reached. This gives you more bed angle without compromising the hoist seals.

Single line systems vs. two line system (see photos in the second section above). Palmer uses a three line system.

There is no air shutoff at the up-fit supply. Palmer uses system protection valve PLUS a ball valve to separate the up-fit from the OEM side of the system for quick trouble shooting of the system. And a one way check valve in the floor manifold block to give extra protection in case of OEM air loss.
