Fitment, Shipping & Product Support

The BDS 1703FPE is a 4-inch radius arm front lift kit with FOX 2.5 Performance Elite external reservoir shocks for the 2019–2023 Ram 3500 4WD gas with factory rear overload leaf springs. Heavy-duty BDS radius arms replace the factory arms, correcting caster at lift height and reducing bushing bind. Gas-tuned front coil springs deliver 4 inches of lift at the correct spring rate for the Ram 3500 gas platform with overload leaf rear suspension. FOX 2.5 PE external reservoir shocks deliver advanced valving and heat-managed damping for sustained off-road and towing performance at lifted height.

2024 Ram 3500 owners — stop here. This kit covers 2019–2023 only. If your Ram 3500 is a 2024 with factory rear overload leaf springs, order 1701FPE. Confirm your model year before ordering.

This kit has four hard fitment confirmations before it applies to your truck.

First — year: 2019–2023 only. The 2024 Ram 3500 with overload leaf requires 1701FPE. The 2018 and earlier Ram 3500 is a different platform.

Second — rear suspension: with factory rear overload leaf springs only. If your Ram 3500 does NOT have factory rear overload leaf springs, order 1702FPE (2019–2023 without overload) or 1700FPE (2019–2026 without overload).

Third — engine: gas-tuned coil springs. Ram 3500 diesel requires a different kit.

Fourth — drivetrain: 4WD only. Ram 3500 2WD is not compatible.

Year and Overload Leaf Variant Reference

SKU Years Rear Suspension Engine
1703FPE 2019–2023 With overload leaf — this listing Gas
1702FPE 2019–2023 No overload leaf Gas
1701FPE 2019–2026 With overload leaf Gas
1700FPE 2019–2026 No overload leaf Gas

How to Confirm Your Rear Spring Configuration

Visually inspect the rear axle leaf spring pack. An overload pack has an additional leaf that sits above the main pack and contacts the axle only under heavy load — visible as an extra leaf that does not contact the axle at rest. Common on higher trim levels and work truck configurations. Text (469) 407-7538 with your VIN to confirm before ordering.


Tire Clearance

At 4 inches of front lift on the 2019–2023 Ram 3500 gas platform, typical fitment runs 35–37-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specifications with your wheel and tire supplier before ordering.


Installation Notes

Professional installation is required. The radius arm lift requires a qualified suspension shop. Do not attempt DIY installation.

Full front-end alignment is mandatory after installation. Do not drive on public roads before alignment is completed.

2024 model year is not covered by this kit. If your Ram 3500 is a 2024 with factory rear overload leaf springs, order 1701FPE. Confirm your model year before purchasing — this kit is non-returnable once installed.

External reservoir routing. Follow BDS and FOX installation instructions for reservoir placement. Avoid pinch points, heat sources, and moving components during routing. Improper reservoir placement can damage the reservoir line and void the FOX warranty.

Rear overload leaf configuration confirmation is mandatory before ordering. If your Ram 3500 does not have factory rear overload leaf springs, order 1702FPE (2019–2023) or 1700FPE (2019–2026). Text (469) 407-7538 if you need help confirming before ordering.

Torque all fasteners to BDS specification. Do not estimate torque values on a 3500-class platform.

The Obsidian Take

The BDS 1703FPE is the correct kit for the 2019–2023 Ram 3500 4WD gas owner with factory rear overload leaf springs who wants 4 inches of front lift with corrected radius arm geometry and FOX 2.5 PE damping. The year range and overload leaf calibration are both specific to this kit — the 2024 Ram 3500 requires 1701FPE, and the non-overload configuration requires 1702FPE or 1700FPE. Neither adjacent kit is interchangeable with this one.

The overload-specific calibration matters on a Ram 3500 work truck or tow rig. The additional spring rate the overload pack introduces at the rear affects front-end geometry balance and ride quality at lifted height — the 1703FPE is tuned for that rear suspension configuration specifically. Installing the non-overload kit on an overload-equipped truck compromises geometry and ride quality under load.

The FOX 2.5 PE external reservoir keeps damping consistent under sustained towing loads and repeated off-road cycles where a standard shock body fades. If your Ram 3500 is primarily a daily driver with light occasional towing and the FOX 2.0 price point covers your use case, text (469) 407-7538 to confirm alternate shock options before committing to the 2.5 PE.

2019–2023 confirmed, overload leaf confirmed, gas, 4WD — the 1703FPE is the correctly-calibrated front-end solution for this specific build window and rear suspension configuration.


Common Questions

Why doesn't this kit fit the 2024 Ram 3500?
BDS engineers separate kits for the 2019–2023 and 2024 Ram 3500 due to specification changes introduced in the 2024 model year. If your Ram 3500 is a 2024 with factory rear overload leaf springs, order 1701FPE. Confirm your model year on your registration or door jamb sticker before ordering.

What is the difference between 1703FPE and 1702FPE?
Both kits fit the 2019–2023 Ram 3500 4WD gas and deliver 4 inches of front lift with the same radius arm upgrade and FOX 2.5 PE shocks. The difference is rear spring calibration — 1703FPE is for trucks with factory rear overload leaf springs and 1702FPE is for trucks without. They are not interchangeable.

How do I confirm my Ram 3500 has factory rear overload leaf springs?
Visually inspect the rear axle leaf spring pack. An overload pack includes an additional leaf that sits above the main pack and contacts the axle only under heavy load — visible as an extra leaf that does not contact the axle at rest. Text (469) 407-7538 with your VIN and we will confirm before your order ships.

Does this kit lift the rear of the truck?
This kit addresses front lift via the radius arm upgrade. Rear lift components are not included. Confirm rear lift requirements with your installer before ordering if needed.

Is this a DIY install?
No. The radius arm lift requires a qualified suspension shop. Professional installation is required.

What warranty does this kit carry?
BDS suspension components carry the BDS No-Fine-Print Warranty. FOX 2.5 PE shocks carry a FOX 1-year limited warranty.
