Fitment, Shipping & Product Support
The BDS 1702FPE 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 without 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. 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. The 2024 Ram 3500 requires 1700FPE. 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 requires 1700FPE. The 2018 and earlier Ram 3500 is a different platform.
Second — rear suspension: without factory rear overload leaf springs only. If your Ram 3500 has factory rear overload leaf springs, a different kit is required — text (469) 407-7538 to confirm the correct overload leaf variant before ordering.
Third — engine: gas-tuned coil springs. Ram 3500 diesel requires a different kit.
Fourth — drivetrain: 4WD only. Ram 3500 2WD is not compatible.

2019–2023 vs. 2024 — Why the Year Split Matters
BDS engineers separate kits for the 2019–2023 and 2024 Ram 3500 model years. The 2024 model year introduced specification changes that require a different kit. If your Ram 3500 is a 2024, order 1700FPE. Confirm your model year on your registration, title, or door jamb sticker before ordering.
| SKU | Years | Rear Suspension | Engine |
|---|---|---|---|
| 1702FPE | 2019–2023 | No overload leaf — this listing | Gas |
| 1700FPE | 2019–2026 | No overload leaf | Gas |
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, order 1700FPE. 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 has factory rear overload leaf springs, a different kit is required. Text (469) 407-7538 to confirm the correct kit before ordering.
Torque all fasteners to BDS specification. Torque specs are included in the BDS installation instructions. Do not estimate torque values on a 3500-class platform.
Text (469) 407-7538 to confirm model year, rear spring configuration, engine, and drivetrain before ordering.
The Obsidian Take
The BDS 1702FPE is the correct kit for the 2019–2023 Ram 3500 4WD gas owner without 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 matters — the 2024 Ram 3500 requires 1700FPE and the two are not interchangeable. If you are ordering for a 2024, stop and order the correct kit.
The FOX 2.5 PE external reservoir is the correct shock specification for a Ram 3500 that sees sustained towing and off-road use. The reservoir manages heat under repeated loading cycles, keeping damping performance consistent where a standard shock body fades. If your use case is primarily daily driving with light occasional towing and the FOX 2.0 price point is the priority, text (469) 407-7538 to confirm alternate shock options before committing to the 2.5 PE.
If your Ram 3500 has factory rear overload leaf springs, this kit is not the correct calibration — text (469) 407-7538 to confirm the correct overload variant. If it is diesel, gas-tuned springs are the wrong rate. If it is a 2018 or earlier, this platform does not apply.
2019–2023 confirmed, no overload leaf confirmed, gas, 4WD — the 1702FPE is the complete, correctly-specified front-end solution for the Ram 3500 owner in this specific build window.
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, order 1700FPE. Confirm your model year on your registration or door jamb sticker before ordering.
How do I confirm my Ram 3500 does not have factory rear overload leaf springs?
Visually inspect the rear axle leaf spring pack. Standard configuration has a main leaf pack with no additional overload leaf — all leaves contact the axle under normal and loaded conditions. An overload pack includes an extra leaf that sits above the main pack and contacts the axle only under heavy load. Text (469) 407-7538 with your VIN and we will confirm before your order ships.
What kit do I need if my 2019–2023 Ram 3500 has factory rear overload leaf springs?
A different kit is required — the overload leaf variant is not identified in this listing. Text (469) 407-7538 with your year, engine, drivetrain, and rear suspension configuration and we will confirm the correct SKU 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.
