Bora Wheel Spacers for Ram 1500 – Precision-Engineered Hub-Centric Spacers
Our Bora wheel spacers for Ram 1500 trucks are engineered to deliver precise hub-centric fitment, allowing you to run wider wheels or achieve an aggressive stance without compromising safety or performance. Manufactured from forged 6061-T6 aluminum with a corrosion-resistant anodized finish, these spacers install between your factory hub and wheel to push the wheel outward, clearing suspension components and filling out your fender wells.
Each kit includes Grade 10.9 hardened steel studs that are pressed and thread-locked into place, eliminating the need for separate lug nuts and ensuring your wheels remain secure mile after mile. We designed these spacers specifically for Ram 1500 models with 5×5.5-inch (139.7mm) bolt patterns, and they're available in thicknesses from 1.25 inches to 2 inches to match your build goals. Whether you're installing oversized tires, leveling kits, or simply want to improve cornering stability with a wider track, these spacers deliver factory-level precision with bolt-on simplicity.

Why Hub-Centric Fitment Matters for Your Ram 1500
Hub-centric wheel spacers like ours center on your Ram’s factory hub rather than relying solely on lug nuts to position the wheel. This design eliminates vibration at highway speeds and prevents uneven stud wear, two common issues with cheaper lug-centric spacers that depend on wheel-to-lug contact for centering.
Our 78.1mm center bore matches Ram 1500 hubs precisely, so the spacer sits flush and bears the vehicle’s weight through the hub surface rather than the studs. The studs’ job becomes purely clamping force, which is how your factory wheels operate. This is especially critical on trucks that tow or haul regularly, where uneven stress on studs can lead to fatigue cracks over time. The same engineering rigor applied to our 1.5-inch wheel spacers across multiple vehicle platforms ensures every Ram 1500 kit meets OEM tolerances for runout and concentricity.
Material and Manufacturing Standards
We forge these spacers from 6061-T6 aluminum alloy, the same material used in aircraft structural components and heavy-duty suspension parts. Forging compresses the aluminum’s grain structure, increasing tensile strength to 45,000 psi and eliminating the internal voids common in cast spacers. Each blank undergoes CNC machining to achieve ±0.002-inch tolerances on the hub bore and bolt-hole diameters, then receives a Type II anodization treatment that builds a 0.0007-inch oxide layer for corrosion resistance.
The Grade 10.9 studs are cold-headed from boron steel, heat-treated to 150,000 psi tensile strength, and pressed into the spacer body with 4,000 pounds of force before receiving red Loctite 271 thread-lock on the receiving threads. This assembly process ensures the studs won’t back out under vibration or thermal cycling, a failure mode we’ve seen in bolt-on spacers that use lower-grade hardware. Every production batch undergoes salt-spray testing per ASTM B117 to verify the anodized finish withstands 1,000 hours of exposure without pitting.
Choosing the Right Thickness for Your Build
How Much Offset Do You Need?
We offer four thicknesses to accommodate different wheel offsets and tire sizes. A 1.25-inch spacer adds the equivalent of 31.75mm of positive offset, ideal for running factory-width tires on aftermarket wheels with insufficient backspacing. The 1.5-inch and 1.75-inch options suit builds with 33-inch to 35-inch tires and leveling kits, pushing the wheel outward to clear upper control arms and prevent rubbing at full lock.
For lifted Ram 1500s running 35-inch or larger tires, our 2-inch spacers provide maximum clearance and deliver a flush fender-to-tire stance. Remember that each inch of spacer width increases your track width by two inches total (one inch per side), which improves stability in crosswinds and cornering but may require fender trimming if your tires are already close to the fender lip. Measure from your current wheel mounting surface to the fender edge at ride height before selecting your thickness, and verify clearance at full suspension compression and steering lock.

Common Questions About Bora Ram 1500 Wheel Spacers
No, you'll use your factory lug nuts to mount the wheels onto the spacer's extended studs. The kit includes a separate set of lug nuts to secure the spacer itself to your factory hub studs. Both sets should be torqued to 130 lb-ft, and we recommend using a calibrated torque wrench rather than an impact gun for final tightening.
If your aftermarket wheels require tuner-style lug nuts with a different seat type, you can still use them on the spacer studs as long as they're rated for your vehicle's weight. Just ensure the thread engagement is at least 1.5 times the stud diameter for safe clamping force.
Wheel spacers themselves don't void your vehicle warranty, but if a failure occurs that a dealer can directly trace to spacer installation, that specific repair may not be covered. Federal law under the Magnuson-Moss Warranty Act requires manufacturers to prove an aftermarket part caused the damage before denying a claim.
Our spacers meet SAE J2530 standards for wheel attachment hardware and are engineered to OEM tolerances, so they won't alter suspension geometry or place abnormal stress on components when installed correctly. If you're concerned, discuss your plans with your dealer's service manager before installation, and keep torque records and receipts to document proper installation.
Measure from your current wheel's mounting surface to the inside edge of your fender at ride height. Subtract at least 0.5 inches for suspension compression and tire flex, and the remaining clearance tells you your maximum safe spacer thickness. For example, if you have 2.5 inches of clearance, you can safely run up to a 2-inch spacer.
Also consider your wheel's offset. If your wheels have high positive offset and sit too far inboard, a thinner spacer may be enough. If you're running aggressive negative offset wheels and need to clear suspension components, you might need 1.75 inches or more. Measure at full steering lock and full suspension droop to check worst-case clearance before ordering.
Yes, our spacers are commonly used on lifted Ram 1500 trucks to provide additional clearance for 33-inch to 37-inch tires. Lifts often bring the tire closer to suspension components like upper control arms and coil buckets, and spacers push the wheel outward to restore clearance.
Just verify that your new track width won't cause rubbing on the fender liner or pinch weld at full compression. Many lifted Ram owners trim the front fender liner slightly or install aftermarket fenders to accommodate the wider stance. Test clearance by cycling the suspension through its full travel before driving, and check again after the first off-road trip.
Yes, our spacers have no effect on your tire pressure monitoring system. The TPMS sensors remain mounted inside your tires and communicate with the truck's receiver module wirelessly, so the spacer sitting between hub and wheel doesn't interfere with the signal.
You'll continue to receive accurate pressure readings and low-pressure alerts exactly as you did with the stock setup. If you're swapping to new wheels at the same time, just make sure to transfer your factory TPMS sensors or purchase new ones programmed for your truck's frequency.
Re-torque all fasteners after the first 50 miles of driving, then inspect them every 5,000 miles or before any long trip. Aluminum and steel have different thermal expansion rates, so the initial heat cycles can cause slight settling that may reduce clamping force.
Use a torque wrench to verify both the spacer-to-hub lug nuts and the wheel-to-spacer lug nuts are still at 130 lb-ft. If you notice any loosening, remove the wheel and spacer, clean the mating surfaces, apply fresh anti-seize, and reinstall with proper torque. This takes ten minutes per wheel and prevents the vibration and stud damage that can occur if fasteners back out.
Yes, when installed correctly our spacers are rated for the full towing and payload capacity of your Ram 1500. The forged aluminum construction and Grade 10.9 studs are designed to handle the cyclical loads and lateral forces that occur during towing, and the hub-centric fit ensures even load distribution.
That said, spacers do increase the scrub radius and lever arm on your wheel bearings and suspension components, which generates slightly higher stress during hard cornering or emergency braking. We recommend limiting your towing speed to 65 mph and avoiding aggressive lane changes when loaded. Inspect all mounting hardware before and after towing trips, and replace any fasteners that show signs of thread deformation or corrosion.
