Installing Pro Comp’s Tundra Long Travel Suspension System

Posted in How To: Suspension Brakes on November 14, 2016

When this owner wanted to upgrade his 2014 Toyota Tundra Platinum Crew Max, he had big plans, but he knew where he wanted to start, and that was with a Pro Comp Long Travel suspension system.

The Pro Comp the kit features ductile cast iron upper and lower extended A-arms. Pro Comp says that with their long lasting, maintenance-free, oversized OE-style pivot bushings, they can maintain factory levels of noise and vibration while increasing strength and durability. They supply extended length tie rod ends to accommodate the 5-inch track width, which increases high-speed stability.

The trucks overall ride height is increased by 3- to 4-inches to allow 14-inches of travel with 35-inch tires. Rear lift height and performance is achieved with longer spring shackles and multi-leaf spring mini packs.

Pro Comp supplies the shocks too, of course. For the front, they are 2.75 coil-overs that feature internal bypass capabilities while the rear units are 2.5’s that also have the Internal Bypass system built right in.

The result is that the Tundra will soon have 14-inches of wheel travel up front with 12-inches in the rear. The track width of the front will increase by 5-inches and with the wheel travel, the Pro Comp fender extensions. All that, and the Pro Comp system is FMVSS 126 compliant (that means legal).

This install happened at the Riverside 4 Wheel Parts store, and they not only did it, the added a few more parts to the Tundra such as N-Fab bumpers, Rigid Industries Radiance LED light bars, and a host of other tricks.

But lets not get a head of ourselves; we’re here to bring you the install of the Pro Comp Long Travel kit, so take a look at how easily this kit goes on. There’s only one piece on the frame that needs to be modified, so this is an install that you could conceivably do in your own garage. Follow along as the pro at 4 Wheel Parts do it, and then give it a try yourself.

Through many incarnations, this Tundra will now become a true off-road capable pre-runner.
Except for a set of R1 calipers and rotors, the stock components are what is found when the wheel is pulled off.
Disassembly of all stock components begins.
With the shock and lower arm removal, it’s time to move on to the install phase.
To give the new suspension enough room, a small piece of the cross member needs to be removed.
The Pro Comp supplied plate will be welded on.
The upper arm is installed. Like the lower, it is a cast piece.
It takes a little muscle to get the huge lower arm in place.
Thread locking material is applied to the threads of the upper shock mount pin.
The upper mount is installed onto the Pro Comp coil-over.
And the shock installed into the Tundra. The 2.75 Pro Comp coil-over shocks feature internal bypass capabilities.
The reservoir mount bracket is bolted to the frame.
Clamps are used to mount the reservoir to the bracket.
Toyota uses this isolator to mount the spindle onto the lower control arm.
It is removed from the stock lower arm and attached to the new Pro Comp unit.
The spindle is installed.
The R1 brake assembly is installed.
Pro Comp supplied longer brake lines with the kit, and they are installed and the brakes bled.
The new sway bar bracket is installed, and hilarity ensues.
The stock sway bar is bolted back in place.
The end links are attached to the Pro Comp lower arms.
With the sway bar in place, the front half of the Pro Comp Long Travel system is on.
Again, apart from the R1 brake upgrade, not much changed about the rear suspension as it came from the factory.
Since part of the leaf pack will be remove and replaced with the new Pro Comp units, a pneumatic driver is used to spread the clips apart.
With the rearend housing held in place by screw jacks, The center bolt is carefully undone.
The main and first leaf are kept, so they are clamped together at this time.
The additional Pro Comp leaf pack is installed.
U bolts are installed.
The Pro Comp shackles are installed and the leaf clips bolted up.
As with the front, longer Pro Comp brake lines are installed
A set of Pro Comp 2.5 Rear Internal Bypass Shocks are installed, but notice the additional “skid plates” that attach to the lower shock mounts. These are there to protect the line that exits the shock and attaches to the remote reservoir. It’s a nice touch.
With the R1 brakes back in place, the job is nearly complete.
A set of 2-inch spacers are installed. With the additional width of the Pro Comp front suspension, it was decided to widen out the rear end a bit.
With another sweep over the bolts to ensure everythings tight, the rear suspension system is done.
With all that extra width, Pro Comp fender extensions are a necessity. They require careful measurement and cutting out the stock sheet metal.
An N-Fab front bumper with has been placed up front. Another N-Fab rear bumper will also be installed.
Rigid Industries light bars will be installed into the N-Fab bumper.
The Pro Comp Long Travel kit consists of cast upper and lower control arms, high quality shocks, rear leaf springs, fender extensions and everything you’ll need to install the system at home. Final wheel travel is 14-inches up front with 12-inches in rear.
