Samurai Lift Kit 4 inch

The Rocky Road Samurai Lift kit 4″… called THE 4 INCHER. What is it? Simply the best riding bolt-on lift kit on the market for your Samurai!

What makes our kit so much farther superior than any other
spring or shackle reversal lift?

First, we use the best riding Samurai springs available.

Two-Stage Leaf Pack: Uses a primary stage for a smooth ride when unladen, while the secondary stage activates to support extra weight when carrying heavy loads.
Draw-Tapered and Rounded-Cut Leaves: Distributes the load progressively over a larger surface area to lower stress at the leaf ends and increase longevity.
Shot-Peened Tension Side: Bombards the tension side of the steel leaves with small shots to reduce spring stress and potentially double the spring’s operational life.
Flat Axle Seat Area: Provides a positive, safe axle mount that lowers stress on the spring while maintaining free camber height.
Bolted Leaf Clamps and Liners: Features bolted clamps that allow for anti-squeak nylon liners and re-greasable anti-friction pads to reduce noise and tip friction.
Fully Scragged and Load Tested: Pre-sets the springs under tension during manufacturing to prevent premature sagging and ensures every pack meets strict engineering specs.

Samurai best 4″ spring lift

We use these springs simply because they’re the best built springs made in the United States, and in the world.

They are THE choice of springs for Jesse James’ projects on his Discovery Channel show Monster Garage, simply because they are the very best in the US. We choose these springs for their reputation, quality, excellence in the industry. They are also the spring of choice for off-road racers, or for high dollar rigs with custom built springs. Rocky Road brings you the ultimate quality and performance of specially designed lifted Samurai springs. We have run these 3″ springs for many years on our Suzukis and absolutely swear by them.

Best Samurai Spring Lift Kit on the planet

Second, articulation is as important to us as a smooth ride, so we don’t stick you with wheel travel limiting, short shocks. Other bolton lift kits and shackle reversals do nothing to modify the shock mounting system on a Samurai. Our kit includes longer shock mounts for THE ONLY BOLT-ON Samurai lift kit on the market that substantially can increase wheel travel through longer travel shocks. Even expensive shackle reversal kits cannot come close to matching our wheel travel due to the simple fact that their shocks limit wheel travel, ours do not. The Rocky Road 4″er Samurai lift kit gives you THE longest travel shock available in any bolton kit, by using our modified taller shock mounts. No welding required.

Every other 4″, or 5″ bolton lift on the market either does nothing to address steering linkage problems, or stops at a simple 3″ pitman arm. What this means to you is compromised handling and bumpsteer if your lift is over 3″. We build our own custom “Zlink” steering linkage and include it with every kit to correct your steering for the full lift height! Along the same lines, we add steel castor shims to make sure your steering stays nice and tight at top speeds on the highway.

Also in the kit are DOT approved rubber brake lines. We won’t even sell stainless steel brake lines because their durability is questionable and lifespan so much less than rubber. Stainless lines cost about 1/2 as much as rubber lines do, but its worth it to us to only go with the best. Stainless lines are only about 3″ longer than stock. Not enough in our book if you’re going over 3″ in lift. We’ve even heard several accounts of the short stainless lines snapping on the trail which were supplied with expensive shackle reversal kits. Quite a dangerous situation which our long rubber lines avoid. Don’t mess around with safety, make sure your kit has DOT approved rubber lines!

Best 4″ Samurai lift for 30-31″ tires

Soft shocks. We sought out the best balanced yet price conscious Rocky Road engineered long-travel shocks for Samurais. They perfectly compliment the light weight of the Zuk and the soft ride of the new Samurai springs. We have designed these shocks to work perfectly with the light weight of the Suzuki. They truly are the top of the line in the offroad industry for Suzukis and you’ll be thoroughly pleased with the quality and comfort of your 4″er ride.

Greaseable shackle bushings. Why greaseable setups over any other poly? Because having greaseable shackles makes your suspension slippery. And a slippery suspension is a smooth traveling and riding suspension. Includes new greaseable shackle bolts and fluted bushings. Provides a far better quality ride than over-priced, over-hyped, shackle reverse kits.

And….. well, the reasons just go on and on…… A 2″ body lift on top of the 4″er provides clearance for the 33″ tires in our photos.

Samurai 4″ lift better than the competition?

Some might ask why would the 4″er be better than the latest passing fad…. the shackle reverse??? There are several reasons. Clearance is one. You install a lift to increase clearance on your vehicle. Shackle reverse towers (some folks call them “fangs”) hang down and dramatically reduce approach angles. Also, with the shackle trailing in back as with S/R kits, they poke down several inches below the original spring perches and really reduce under frame clearance. 31″ tires do not fit on S/R kits without severe rubbing and tire damage. Further, there is the issue of stability. ‘Brake dive’ is a common problem with shackle reversal in emergency braking which does not occur in non-Shackle Reversed lifts. This is why the manufacturer put the shackles on the front of your vehicle to begin with. If all it took for a smooth ride was to put the shackles in back, Suzuki would have made them this way from the factory (not to mention Jeep with the Wrangler, and Toyota with the Landcruiser). There is a reason the shackles are up front, and it is a safety and stability issue.

Another concern, legality. In places throughout North America and around the world, it is illegal to change the configuration of your suspension as with the shackle reversal lifts. Retailers of shackle reverse systems won’t tell you they’re selling an illegal suspension, or may flat out deny it. Ultimately, you are responsible for what goes on your rig. The 4″er lifts your vehicle, yet keeps the configuration in stock form with the shackles up front to comply with applicable regulations. Again, its a safety issue, the 4″er is legal, shackle reverse kits may not be.

4″er Samurai Lift Kit Contents

Finally, your 4″er will give as good or a better ride as any shackle reverse kit on the market. This is due to the top quality springs we use and the super plush Rocky Road engineered shock. AND, the 4″er will give you better articulation by simple virtue of repositioned shock mounts for long travel shocks. Kit should fit most 31″ tires, check fitment before tire purchase though. OME springs may only fit up to 30″ tires.

The Rocky Road 4″er includes the following items for the most comprehensive lift kit on the market today for Samurai:

3″ lift springs
- Military Wrapped Eyes: The second leaf wraps partially or fully around the main leaf’s eyelet. This acts as a vital secondary safety measure to prevent the axle from detaching if the main leaf snaps.
- Premium Spring Steel: Constructed using high-carbon alloy. These materials provide high tensile strength and a lower modulus of elasticity for consistent flexing and long-term durability.
- Shot-Peened Leaves: The individual leaves undergo a shot-peening process to compress the surface metal, dramatically increasing their resistance to stress, cracking, and metal fatigue.
- Tapered and Thinned Ends: The ends of the leaves are tapered. This progressive thinning ensures a smooth transition of stress across the spring and prevents localized weak spots.
- Anti-Friction Interleaf Liners: High-end springs integrate Teflon, graphite, or specialized wear pads between the leaves. This minimizes the inherent metal-on-metal friction for a quieter, smoother ride and allows the springs to articulate properly.
- Bolted Spring Clamps: Instead of cheaper, crush-style clamps, premium leaf packs use bolted clamps. These allow the leaves to separate slightly and move independently, reducing friction while preventing the plates from “fanning out” sideways.
