Tips on installing the 2.5 Ultimate Lift Kit on FJ40 Toyota Land Cruiser
All the parts are on your floor and ready to install the 2.5 Ultimate Lift Kit on your FJ40 Toyota Land Cruiser?
Here are some quick visual cues to help you get everything laid out on your floor in the orientational direction of which you will be installing the springs, shackles and pins.
Make it easy on yourself and get everything laid out and organized so you are not fighting the heavy springs with wasted effort because you grabbed the wrong ones and attempting to install them in the wrong direction! It happens, especially if you are working in the tight confines of a small garage!
Which Springs Where
Fronts Spring – Visual note: more leafs than rears
Rear Springs – Visual Note: less leafs than fronts
From the Locator Pin (roughly center of spring), from the pin to the end of the spring, one side will be longer. The longer side goes to the end of the vehicle. The longer side of the front spring goes toward the front bumper and the long side of the rear spring goes towards the rear bumper.
Each shackle has two plates. The outside plate is flat and the inside plate is the “J-shape.” Thus the two shackles should be orientated as such [ “I-L J-I” ] on the vehicle so that way those Jeep LJ’s get scared when you roll up on them on the trail with their initials just below your front and rear bumpers! 😉
The Zerk fitting on the Shackle Pin will point outward of the vehicle for proper fitment. (also for ease of servicing).
We use a red high temperature wheel bearing grease for the pins.
Just in case you got all happy and tore all the boxes open, pulled all the parts out and laid them on the floor. You started your garage’s wood burning heater with the cardboard boxes… How do you determine what shock go where? Typically, Long shocks go in the rear and the short shocks mount in the front of your FJ40 Land Cruiser. But sometimes, you could have all four shocks be the same size.
When installing the bushings, the bores are most likely a bit rusty and will make getting the bushings pressed in a chore! Lightly sand out the bores and grease up the O.D.’s of the bushings to aid in getting them in. We use a red high temperature wheel bearing grease for both the O.D.’s of the bushings as well as the pins via the Zerk fittings.
When installing the RL1037 FJ40 Leaf Spring U-Bolt Plates, perform the final tightening of the U-bolts with suspension at “static ride-height” (NOT HANGING IN THE AIR!) Also hand-torque U-bolts to 90ft/lbs. Tightening suspension components while “suspended” (without static ride-height load) could prematurely loosen and cause catastrophic failure. Double-check torque specifications after 250-miles.
It’s OK to use your MAC TOOLS 20V MAX 1/2″ Drive Brushless Mid-Torque Impact Wrench to do the initial tightening, but don’t torque them all the way! IT IS IMPORTANT to NOT over-tighten with the Impact Wrench!
HAND-TORQUE with a torque wrench to 90ft/lbs. for the final tightening of the U-Bolts!!!
! Check torque specifications (90ft/lbs) after 250-miles !
!! Double-check torque specifications (90ft/lbs) after 250-miles !!
