This BDS Suspension extended travel 4-inch Radius Arm Lift kit Designed specifically for Diesel-powered Ram 2500 trucks improves ride quality, handling, and off-road capability while maintaining excellent on-road comfort. With clearance for up to 37-inch tires, it delivers a more aggressive stance while preserving proper driveline geometry and everyday drivability.

Up front, the kit features Pro-Ride coil springs engineered to support the added weight of the Gas platform while providing a smooth, controlled ride. Heavy-duty replacement radius arms play a critical role in the system by properly positioning the front axle and correcting caster angles lost when lifting the truck.

By restoring proper suspension geometry, these radius arms improve straight-line stability, steering return-to-center, braking control, and overall ride quality, while their reinforced construction adds strength and durability for both on-road and off-road use. A Track bar relocaton bracket is included to properly center the front axle and maintain precise steering geometry.

Also included is a brand-new 10-bolt transfer case indexing ring engineered to clock the transfer case for optimized driveline angles and increased suspension droop. This indexing ring features an all-new, industry-leading seal developed specifically for motorsports applications, delivering superior sealing performance, reduced friction, and long-term durability under extreme heat and speed.

By properly clocking the transfer case, this system provides longer suspension travel and improved off-road capability compared to basic lift kits that do not re-index the transfer case. Additional components include sway bar links, brake line brackets, and premium shock absorbers matched to your selected configuration.

In the rear, lift is achieved using a pair of Pro-Ride BDS coil springs. Matching rear shocks are included to maintain balanced ride quality and consistent performance from front to rear.

Shock options allow you to fine-tune ride quality and performance to match your driving style. BDS NX2 Nitro shocks provide a comfortable, well-controlled ride for daily driving and light off-road use.

FOX 2.0 Performance Series IFP shocks feature aluminum construction and internal floating piston technology for consistent, fade-free performance. FOX 2.5 Performance Series IFP shocks increase oil capacity and cooling for enhanced damping control in more aggressive terrain.

At the top level, FOX 2.5 Performance Elite Series shocks with Dual Speed Compression (DSC) adjusters deliver race-inspired performance and tunability, allowing independent adjustment of low- and high-speed compression for maximum control and versatility.

Built with BDS Suspension’s uncompromising commitment to strength, ride quality, and long-term reliability, this 4-inch radius arm lift kit is the ideal upgrade for Ram 2500 owners seeking improved handling, corrected suspension geometry, increased suspension travel, and confidence-inspiring performance both on and off the road.

Questions?

WE HAVE ANSWERS

How long til' I get my order?

Small items arrive to you in under 1 week

Larger products like full suspension kits must ship freight and can take 1-3 Weeks

Are Installation Instructions Included?

Instructions are included for most parts that require any sort of knowledge to install.

Here's what to do if your parts come WITHOUT instructions:

1. Some parts are genuinely common sense on how they get installed

2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video

3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer

4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed

ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.

Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way

What is your return policy if the part doesn’t fit or isn’t what I expected?

If the part was NOT installed, we accept returns within 14 days of delivery.

If the part WAS installed (or attempted installation), we cannot accept a return.

Do your parts come with a warranty?

All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.

I found a better price somewhere else, can you beat it?

YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.

Do you give out discounts or sponsorships?

NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
