**TL;DR:** Ram trucks tow, haul, and work hard. We check **brakes, hitch, and tires** for the load, match oil to the Chrysler spec, and inspect **air suspension** where equipped.

We service Ram pickups and ProMaster vans as an independent shop, including the Ram 1500 with Hemi or EcoDiesel engines, many heavy-duty 2500 and 3500 trucks, and ProMaster cargo vans. Ram lists a Chrysler oil standard in the manual, and many trucks use air suspension or tow regularly. We inspect for those loads and write the estimate first.

## Which Ram trucks and vans do you service?

Mostly half-ton pickups and vans, with heavy-duty trucks by confirmation.

- [Ram 1500](https://goodyearelitetireupland.com/vehicles/ram-1500/): Hemi V8, V6, and EcoDiesel versions, used for work and family.
- Ram 2500 and 3500: gas and diesel heavy-duty trucks; call (909) 608-7699 to confirm before bringing one in.
- ProMaster: front-wheel-drive cargo vans used by trades and delivery drivers.
- Older Ram and Dodge trucks with high miles.

Ram shares engineering with Jeep and other Stellantis brands; see [domestic vehicles](https://goodyearelitetireupland.com/vehicles/domestic/).

## What should Hemi and eTorque owners know?

Oil quality and level matter on the Hemi. Many Hemi engines use cylinder deactivation, which depends on clean oil to work smoothly. Use the grade and Chrysler material standard in your manual and change it on schedule, or sooner if you tow.

Some 1500s also have eTorque, a mild-hybrid system with a 48-volt battery and a motor-generator that replaces the alternator. It helps with stop-start and smooth acceleration. We check the 12-volt battery and belt system, and we treat eTorque component repairs with care, sending them out when they need specialist tools.

If you hear a tick or get a misfire code, book a [check engine light diagnostic](https://goodyearelitetireupland.com/services/check-engine-light-diagnostics/) early.

## How do you service Ram air suspension?

By inspecting the air springs, lines, compressor, and height sensors, and by putting the system in the correct mode before lifting. Many Ram 1500s have four-corner air suspension that raises and lowers the truck. Lifting it without the right setting can confuse the system.

Signs of an air suspension problem:

- One corner sits low after parking
- Compressor runs often or loudly
- Warning message on the dash
- Truck will not change ride height

We diagnose the leak or fault and give you a written estimate. See [suspension, shocks, and struts](https://goodyearelitetireupland.com/services/suspension-shocks-struts/).

## What should you check before towing with a Ram?

Tow rating for your exact build, payload on the door label, hitch and wiring, brake controller, and tires. Rams can have very different tow ratings based on engine, axle ratio, and cab.

| Check | Why |
|---|---|
| Tire load range | LT tires may be needed for heavy trailers |
| Brake controller | Needed for trailers with electric brakes |
| Rear air suspension | Can help level a loaded truck if working |
| Cooling system | Long grades with a trailer raise temperatures |

The [towing and hauling](https://goodyearelitetireupland.com/vehicles/towing-hauling/) page walks through a full pre-trip check.

## What wears first on a Ram ProMaster?

Front brakes and front tires, since the ProMaster is front-wheel drive and carries weight over the front axle when the cargo area is empty and in the rear when loaded. Work vans also stack up miles and idle time.

We set up service by mileage, keep records by unit number for businesses, and check brakes, tires, and suspension on each visit. See [work vans and cargo vans](https://goodyearelitetireupland.com/vehicles/work-vans-cargo-vans/) and [fleet vehicles](https://goodyearelitetireupland.com/vehicles/fleet/) for more.

## What tire fitment rules apply to Ram trucks?

Load comes first. A Ram 1500 often leaves the factory on passenger-type tires, while heavy-duty 2500 and 3500 trucks use LT tires with a higher load range. Swapping to a tire with a lower load rating than the placard lists is not safe, no matter how good it looks.

| Truck | Typical tire type | Notes |
|---|---|---|
| Ram 1500 | P-metric or LT, depending on trim | LT tires ride firmer but resist damage |
| Ram 2500 and 3500 | LT, often load range E | Pressures for a loaded truck are on the placard |
| Rebel and off-road trims | All-terrain tires | Rotate on time; lugs wear fast on pavement |
| ProMaster | Van-rated tires | Load index matters when full |

Other fitment points:

- **Leveling kits and larger tires:** change speedometer reading and can rub at full lock.
- **Dual rear wheels:** inner and outer tires need matched tread and pressure.
- **TPMS:** some heavy-duty trucks use separate pressure settings for loaded and empty use; check your manual.

We check load range, date codes, and pressure before any tow.

## Where do Ram brakes and steering parts wear, and what goes to a specialist?

Heavy trucks wear front brakes, steering joints, and ball joints the fastest. Heavy-duty Rams with a solid front axle can develop a violent front-end shake after bumps when track bar or steering parts loosen, much like a Wrangler.

Wear points we check on a Ram:

1. Front pads and rotors, which carry most of the stopping load.
2. Tie rod ends and the drag link on heavy-duty trucks.
3. The track bar and its bushings on solid-axle trucks.
4. Steering damper condition, without treating it as a cure.
5. Rear leaf springs and shackles on trucks that haul.

| Stays with us | Goes to a dealer or diesel specialist |
|---|---|
| Brakes, tires, alignment, steering parts | Warranty, recall, and software updates |
| Oil service and filters | Many diesel emissions repairs |
| Air suspension diagnosis | eTorque component repair when special tools are needed |

To prepare, tell us your usual trailer weight, hitch type, and how often you tow. Photos of any warning messages help too.

## Needed now versus can wait

### Needed now
- Air suspension leak leaving one corner low
- Brake controller not working before a tow
- Misfire or lifter tick on a Hemi
- Front brakes at minimum on a loaded ProMaster

### Can wait
- Leveling kit for looks
- Oversized off-road tires on a highway truck
- Aftermarket tuner
- Bed storage and rack accessories

## Our process

1. **Confirm build and use:** We read engine, axle, suspension type, and ask how much you tow or haul.
2. **Set the truck for lifting:** Air suspension trucks are put in the correct mode before going on the lift.
3. **Inspect load systems:** Brakes, tires, hitch, air springs, and cooling system get checked with photos.
4. **Write the estimate:** Safety and towing items are listed first with a total before work.
5. **Repair and road-test:** Approved work is completed and the truck is driven to check ride height, brakes, and shifting.

## What's included

- Oil matched to the Chrysler standard

## Frequently asked questions

### Do you work on the Ram 1500 with air suspension?

Yes. We set the system to the proper mode before lifting, inspect air springs, lines, and the compressor, and diagnose leaks. You get a written estimate before any repair.

### What oil does my Hemi need?

Use the grade and the Chrysler material standard listed in your owner manual or on the oil cap. Change it on time, and consider the severe schedule if you tow. We confirm by VIN and note the oil on your invoice.

### Do you service Ram 2500 diesel trucks?

Many, yes, for routine maintenance, brakes, tires, and inspections. Call (909) 608-7699 with your model and the job so we can confirm before you drive over. Some diesel emissions repairs need specialist equipment.

### Can you service our ProMaster work vans?

Yes. We handle oil, brakes, tires, suspension, and diagnostics, and we can keep records by unit number for businesses. Ask about a fleet account if you run several vans.

### Should I put LT tires on my Ram 1500?

It depends on how you use the truck. LT tires resist punctures and carry heavy loads well but ride firmer and can reduce fuel economy. If you tow near your limit or drive rough roads, they may make sense. We compare options against your placard.

### Why does my Ram 2500 shake hard after hitting a bump?

Heavy-duty Rams use a solid front axle, and a loose track bar, worn tie rod ends, or worn ball joints can set off a strong shake. Slow down gradually when it happens. We inspect the front end, show you the loose part, and repair the cause.
