DJM LOWERS A '04 FORD FOUR-BY

Why would anyone want to lower a 4WD vehicle? Because we at DJM are in the lowering business, we obviously have a special interest in the answer to this question. The suspension of stock four-wheel-drive vehicles is deliberately very high to provide great ground clearance. The factories suspend their four-bys high enough to clear rocks, gullies, fallen trees and whatnot usually encountered in serious off-roading. Nevertheless, there are four-by owners who would like to lower their vehicles. Recently, we met just such an owner and we couldn't resist questioning him about his desire to drop his '04 Ford F-150 four-by. "I think trucks look better when they are lowered," explained Pete. "I'm a construction contractor and I use my pickup for business and pleasure. It's my daily driver. I chose four-wheel-drive because it gets me to just about every job site regardless of how rough the location. I just wish my truck wasn't quite so high off the ground. "No, I'm not an off-roader," he continued. "But I do like vehicles and I especially like my Ford. I guess I'm convinced if it were just a few inches lower, it would be better looking and have a more attractive stance." "Beside the appearance, is there anything else about the high factory suspension that you don't like?" we asked. "I didn't think getting in and out of a high four-by would bother me," he replied. "After all, I am six feet tall. But after living with this truck for a while and getting in and out of it as many times a day as I do, I'll tell you it'll wear you out. And when you have to load something heavy into the bed or the cab, you sure realize how high it really is. "And don't think my wife doesn't complain every time she has to get in it or put the kid's car seat in it or load something in the bed," he added. "Listen to her and you'd think it's a monster truck, but she's only five-four." Everyone knows that lowering a four-by is a "no-no" because, if it's lowered, its effectiveness in the off roads is compromised. And that's true. But it all depends on how the four-by owner defines "off roads." If his off-roads are the rutted dirt roads to a job site, like Pete, or the steep driveway into the local McDonalds or the three-inch snowfall that comes every winter or the icy surfaces that follow, then lowering his four-by just "ain't" going to matter. This guy may be a serious four-by owner, but please don't tell him he's not a serious off-roader. However, for the truly serious off-roader, lowering his four-by would surely compromise its effectiveness in the off roads. From our conversation with Pete, the contractor, we realized that he was certain his Ford four-by, or any four-by for that matter, just couldn't be lowered. At DJM, we know that's not true. Not only can we lower four-bys, but we can lower them without adversely effecting their four-wheel-drive capability. We agreed to come to the rescue of Pete, the contractor, with a 3½ X 4 drop for his F-150 four-by. Times change. And like all automotive technology, the science of suspension modification advances. Witness those DJM twin sleeves that used to require drilling for grease fittings, but now come pre-drilled in all DJM kits. Like all DJM drop kits, the kit we installed here for the late model Ford F-150 4WD features a stronger flip bracket and now clamps the rear end securely and accurately so that the installer is able to adjust the pinion angle to prevent rear end vibration. The entire kit-available in 2½ or 3 ½ -inch front drop and 4 or 5-inch rear drop-is direct bolt on and requires no drilling, welding or modifications of any kind. Shock replacement is required in the rear only. Stock front shocks are retained. Full front-end travel is retained because the spring and strut have not been modified in any way. The best news is that the F-150 4x 4 works well as an off-road vehicle even after the DJM drop. Oh, sure, as we inferred earlier, ground clearance isn't quite as high and rock crawling is out of the question. But let's face it. Serious off-road motoring is a rare, if ever, experience for most four-by owners. So the DJM drop demonstrated herein will work well for most Ford 4WD F-150 owners. The accompanying photos follow the highlights of the installation of the DJM drop kit and the resultant 3½ X 4 drop of Pete's F-150 4x4. Please note that complete, easy-to-follow installation instructions for this install are available on DJM's website: www.djmsuspension.com.

1.Stock ride height of the '04 F-150 4x4 measured from the
center of the wheel to the lip of the wheel well registered 34 ½ " in
front and 37 "in the rear |

#2. DJM's new lower control arms for lowering both 2WD and 4WD
vehicles come ready to install and feature adequate clearance for the 4WD shaft
and turning radius. |

#3. The grease fittings for the twin tube sleeves are not
installed at the factory to prevent damage in shipping, but must be screwed in
place by the installer and, with the inner tube in place, grease should be
applied until it leaks out at the bushing to be sure everything is flowing
properly. |

#4. After the vehicle is jacked up and braced securely, the tie
rod end is removed. |

#5. The tie rod end is then removed |

#6. By use of a bottle jack, the weight is taken off the shock
bolt and, when the level is correct, you can pull the bolt out easily by hand. |

#7. After loosening the lower ball joint nut and removing the
spindle from the control arm, our installer completely removed the control
arm. |

#8. The new control arm is installed. |

#9. A bottle jack is used to line up the shock bolt so the bolt
can be slipped in while making sure the nut is on the same side as it came
off. |

#10. The control arm is then pushed rearward so the alignment is
at the back half of the elongated hole and tightened. |

#10. The control arm is then pushed rearward so the alignment is
at the back half of the elongated hole and tightened. |

#12. Then 3/8 inch is trimmed from the inner tie rod using a die
grinder with a cut-off wheel very carefully so as not to damage the
treads. |

#13. The tie rd end is also trimmed 3/8th inch. |

#14. Now the trimmed tie rod end is refitted to the trimmed tie
rod; the assembly is reinstalled and the front drop is complete. |

#15. Our installer gets ready to start the rear installation by
removing the rear wheels. |

#16. He then loosens the driver's side U-bolt holding the leaf
spring. |

#17. The U-bolt and spring plate are removed. |

#18. The leaf spring is removed. |

#19. Our installed then removes both center bolts holding the
leaf pack together. |

#20. He then reinstalls the aft center bolt by inverting it so
that the locating pin will align with the new DJM bracket. |

#21. The extension or lifting hanger is installed. |

#22. Our installer taps the bracket thoroughly to seat it. |

#23. He then tightens the bolt that prevents the bracket from
moving. |

#24. Here's the finished bracket ready to accept the original
spring. |

#25. He reinstalls the spring into the new bracket. |

#26. The stock bump stop is then removed. |

#27. The DJM bump stop screws easily into the stock mounting
clip. |

#28. The bolts for the top plate to the flip kit are installed,
but not tightened until the pinion angle on the rear end is adjusted. |

#29. The new DJM U-bolts are installed. |

#30. The new DJM spring plate is installed. |

#31. After adjusting the pinion angle to prevent rear end
vibration, our installed tightens the U-bolts and top plates to lock the whole
assembly together. |

#32. The stock rear shocks are replaced. |

#33. The new DJM shocks are tightened |

#34. Contractor Pete's '04 F-150 4 by 4 is
3½" lower in front and 4" lower in the rear, has a greatly improved
stance and no more height problems, for Pete's sake. |
