Slight Lift for 2004 F-250

Question: I have a 2004 Ford F-250 Superduty 4×4, which currently has factory suspension. Looking for spring/shock or airshocks to give my truck a  small lift in rear. What do you suggest?

Answer: Shockwarehouse carries a Rancho Add-A-Leaf spring for the 2004 F250 that will give approximately 2-3 inches of extra height in the rear, depending on the condition of your stock springs.  This part is installed alongside your factory springs.  This is a much better choice than an airshock because it doesn’t put the extra stress of holding the truck up on the shock mounts and allows the shock to do its job, which is dampening the ride rather than supporting the truck.   You can see our page for that part here:
And all of the parts we carry for your truck are right here:

We can also recommend Bilstein 5100 series shocks to go with your rear lift; you can see those here:


Q.: My husband and I have been enjoying a used Toyota Tacoma mini motor home but we need new air shocks.

Would the Airlift 57113 be a good choice? Do we order two or just one?

Does this particular item require drilling? Are installation directions sent with this item?

A.: The Airlift 57113 is a kit, and includes two air springs and all the hoses, brackets, bolts and other parts to install. You only need to order one kit. The kit includes detailed instructions, and these can also be downloaded free from Airlift’s website.

The Airlift Super Duty Air Spring Kit (57113) fits Toyota mini motorhome chassis 1986-1994. Commercial trucks, ambulances and tow trucks also use Air Lift LoadLifter 5000 kits for the reliable, safe handling they provide even under heavy loads. The LoadLifter 5000 is currently eligible for a rebate.

The 57113 does require drilling, usually just a few holes in the frame to attach the upper bracket to the frame.

We had a question about a 1998 Chevrolet motorhome, chassis designation P-37, coil springs with airbags in front and leaf springs in the rear, and a tag axle.

(A tag axle is a non-drive third axle positioned behind the rear drive axle of a recreational vehicle with one or two tires on each side; its chief advantage is extra carrying capacity.)

Our shocks and accessories for the P-series can be found here:


We recommend the Bilsteins, B46-1173 / B46-1587.



One more reason to keep your suspension system in good repair: your vehicle may be taking more damage from poorly maintained roads than you might realize.

Much road damage is due to time and the weather, but overweight freight trucks tear up the roads, too. A recent study by TRIP, a nonprofit research prganization in Washington, found that 28 percent of major roads in the U.S. are in “poor condition”–chiefly due to potholes and cracks.

source: eremedia.com

According to the U.S. Department of Transporation, the percentage of roads in mediocre to poor condition approaches 70% in some states.
The same USDOT report estimates dollar values of annual total extra vehicle repairs caused by bad roads, and for some states these are in the billions. It works out to anywhere from $60 to $600 per motorist per year for the costs of driving on roads in poor repair. See the state-by-state chart.

Moreover, in the U.S., the condition of roads is the biggest obstacle to self-driving car technology (we like doing our own driving here at Shockwarehouse, but still).

Bad road conditions that have been neglected for a long period of time, such as a pothole that remains open for weeks, can cause serious damage to your car; if you have damage like this, take pictures. You may be able to address a successful claim to the appropriate city or local government.

And when you need replacement shocks and struts, Shockwarehouse is here for you.


A customer wrote: “I got new rims and new 33″ tires. I am also about to purchase a 4″ lift leveling spindle kit with 2″ blocks in rear. So I need to know what kind of shocks I can get for the lift and not spend a lot of money.”

We have a page on lifted shocks on our website.

Our mechanic answers: “If you have already tried a stock length shock and that wasn’t long enough, you may need a longer shock. Be sure and check with the lift kit manufacturer to be sure. There’s no way for us to tell, if you didn’t get the lift kit from us.

First, check our online catalog for longer shocks.

If you need a custom shock length, some of our manufacturers offer universal type racing shocks. Look at some spec sheets here.


Customer Question from our Archives: How can I keep my 2002 Chevy Silverado from sagging when I haul a heavy load? Should I get rear air shocks?

At Shockwarehouse we have some Airlift products that are actually better than air shocks. Air shocks can put a lot of stress on the shock mounts, which aren’t really designed to hold the truck up.

The Airlift Air Cell and Air Spring Kit are both designed to keep your truck from sagging. The Air Cell (52203) is basically a heavy duty air bladder that doesn’t need to be adjusted and will add extra support.

The Airlift Air Spring Kit (59501) is adjustable just like an air shock. Use an external compressoror get an onboard compressor from us if you’d like to adjust it on the fly. The benefit of the air spring is that when you aren’t towing or hauling, it won’t affect your truck’s ride at all, since you can just deflate it.

Arnott’s completely new (not remanufactured) air strut for the front of the 2004 to 2010 Jaguar XJ series with Comfort Suspension (AS-2888) features a custom-made and tuned premium monotube shock absorber designed to provide a responsive yet comfortable ride.

The Arnott-designed strut eliminates many of the common high wear weaknesses of the OE strut, such as the leaky upper seal, noisy upper mount, and the weak lower rubber seal. The Arnott strut is built with a new Continental ContiTech air bladder, heavy-duty crimping rings, new O-Rings and a new, OE-inspired dampening coil. The strut fits Jaguar vehicles with comfort suspension. Arnott recommends replacing both Jaguar XJ O.E. front struts at the same time.

The new aftermarket Air Strut for the X350 Chassis and the X358 Chassis  replaces OE Part Numbers C2C41349, C2C41339, C2C41347, C2C28533, C2C28409, C2C25696, C2C24412, C2C39763, and C2C31016.

Nivomat suspension units have been used for more than 30 years on a variety of domestic and foreign vehicles, including Volvo, Ford, Opel, Saab, GM, Jaguar, Alfa Romeo, Rover, Mercedes, Mitsubishi, Kia and others. The Nivomat self-leveling shock has a lightweight coil spring and gradually, over a mile or two, self-adjusts to normal ride height when heavily loaded. You may even notice with Nivomats that your parked car settles a little bit after a couple days. Read more about them on our website.

If you are wondering if you have Nivomats, check your manual, or try to get a look at them. They will only be in the rear. Nivomats have a thinner end toward the eyelet (although Monroe Nivomats and some others have a built-in accordion boot cover). If you can’t see the entire unit and you don’t want to take the tire off, but you can see the bar code, try scanning the bar code with your smartphone and a cheap or free bar code reader app such as Barcode Express.

If your vehicle has manufacturer-installed Nivomats, these will need to be replaced with Nivomats, because these shocks (unlike most) actually help hold up the car. If you replace them with non-Nivomat technology your rear end will sag. That’s right, your rear end will sag. Nobody wants that.


The Nivomat is on top.


GM trucks and SUVs have Service Parts Identification Label sticker inside the glove box. This label will have your VIN, Wheel Base, Model designation and a list of 3-digit/character RPOs (Regular Production Options). If you see code “Z55” on the label, you have Autoride electronic suspension. Thanks to our friends at Arnott Industries for sharing this.
