Complete your shop setup with this exceptional Ranger tire changer and wheel balancer combo — the perfect match for high-volume tire shops, gas stations, independent garages, and anywhere tire service is a daily priority. The R745 RimGuard™ 21" capacity tire changer pairs seamlessly with the DST-2420 Dynamic Wheel Balancer to create a comprehensive tire service solution designed for speed, precision, and long-term reliability. Whether you're handling passenger cars, light trucks, trailers, or daily commuters, this combo delivers professional-grade performance without unnecessary complexity. Get the tools you need to change and balance wheels quickly, accurately, and profitably — with Ranger's proven durability and engineering excellence backing every job.
The Ranger R745 is a fixed tower tire changer that delivers exactly what busy shops demand: reliability, speed, and no-nonsense performance. Ideal for gas stations, roadside tire shops, small personal operations, or as a dependable backup machine, the R745 features a swing-arm design for fast tire loading and robust steel clamps perfect for passenger cars, daily commuters, spares, and trailer tires. There's nothing fancy here — just solid, dependable tire service equipment built to handle the heavy volume your shop demands.
Only pay for what you need. The R745 is engineered with a rigid tower design and a sturdy body featuring a 45mm hexagonal vertical shaft and hardened-steel horizontal outrigger support arm. This construction eliminates flex during tire service procedures, reducing the risk of damaging expensive wheels. Linear guide bearings make vertical and horizontal adjustments smooth and effortless — and they're completely maintenance-free for the entire life of your tire changer.
High-torque electric turntable with faster operating speeds and reverse-direction control makes tire swaps easier and reduces the risk of tire damage — especially critical for low-profile and run-flat beads that need time to relax. The dual pneumatic cylinders ensure smooth, consistent clamping action, and the 4 internal/external clamps handle a wide range of wheel sizes with inside clamping from 12" to 20" and outside clamping from 10" to 16".
Enhanced pneumatic bead breaker blade provides durable construction and many years of dependable service. A rubber bump stop ensures smooth arm return, reducing shock loading and protecting moving parts. The advanced blade design offers better mechanical strength and longevity compared to standard blades, letting you break even stubborn beads with confidence.
100% forged steel foot pedal levers are remarkably lightweight, durable, and non-reactive with chemicals, liquids, and other shop elements. As the most-exposed part of your tire changer, these foot pedals are built to last — unlike cast-iron pedals found on many other brands, which are heavy, prone to rust, and require more maintenance over time.
Sealed tight for minimal maintenance. Every main-lead electrical terminal, auxiliary switch, and motor enclosure is air-tight, dust-free, and utterly safe from contamination. The maintenance-free gearbox features an impressive oil and grease tank that releases heat and better lubricates components. Internal baffles work with a constant-seating stress flange gasket to provide low operating temperatures through superior venting and zero fluid leakage.
High-pressure polyurethane pneumatic tubing constructed with a smooth, seamless bore improves airflow. The tubing offers high abrasion resistance, high burst tolerance, and total kink resistance. The specially engineered drive-belt features convex sidewalls that evenly disperse wear, significantly extending the lifespan of your tire changer. Flex-bonded cords and flex-weave covers keep away contaminants like water and oil.
Upfront controls are logically arranged for speed and ease-of-use. The aluminum pneumatic cylinders feature internal end-of-stroke cushions that protect seals, wear bands, and piston rods, and are continuously lubricated during use for extended service life.
Alloy steel mount & demount head with an equi-dimensional shape lets you change tires without repositioning the tool head. The micro-smooth surface ensures mounting and gliding tire beads into place is effortless. The hardened alloy steel construction is specifically designed to protect tires at all times, even in the busiest shop environments. The 45mm spring assist hexagonal vertical tool shaft and manual lock tool holder keep the mount-demount tool head perfectly still during operations.
All the extras come standard. A soap bucket and brush, turntable jaw covers, bead-breaker blade boots, and mount/demount head covers are included — everything can be stored right in the tire changer. A steel tire iron and bead lever tool also comes with your purchase, an indispensable tool every tire changer operator should be familiar with. The pistol-type tire inflator with integrated air dump valve and sure-grip clip-on valve chuck permits full-function, hands-free operation.
Standard tire changer features include: Water filter, oiler/lubricator, air regulator, breaker bar, large soap/lubricator bucket, brush, traveling drop-center hold down device, inflation restraint device, and tool tray/bin storage. Optional motorcycle turntable clamps are available if you need to service motorcycles — they add versatility and are rugged and dependable.
The Ranger DST-2420 wheel balancer (supersedes DST-1200) is a highly accurate and dependable no-frills balancer featuring Ranger's proprietary Digital Sensor Technology for critical reliability and repeatability. Now handles wheels up to 30" diameter and 18" width, making it ideal for cars and light trucks. From one-bay shops to high-volume tire stores, the DST-2420 is built with gritty toughness that produces perfectly balanced wheels day after day, around the clock. This zero-tolerance performer features Ranger's proven Direct-Axis drive system, accurate to within +/- 1 gram (0.035 oz), ensuring wheels are balanced vibration-free.
The DST-2420 automatically calculates the exact weight needed to achieve optimal balance for almost every tire and wheel configuration on the planet, and brightly displayed LED indicators mark the exact amount and location in just 6 to 9 seconds. A full menu of time-saving features includes Dynamic, Static, and 3-Alloy balancing modes, allowing you to balance OEM wheel configurations and performance wheels with minimal effort and speed. An audible alarm and LED display identify exact weight amounts and precise positioning for perfect balancing every time.
Digital Sensor Technology (DST): Highly accurate 64-bit architecture and single-chip technology increase productivity and offer unprecedented speed and accuracy — especially when using sophisticated balance and weight placement techniques required for newer high-tech OEM and aftermarket wheels. Single-chip circuit board architecture provides an inherent performance and reliability advantage compared to multi-chip implementations. Extremely fast dedicated hyper transport protocol allows data to communicate with the micro-processor at much faster speeds, resulting in lower power consumption and dissipated heat.
Multi-Directional Quartz Piezoelectric Load Sensors: The DST-2420 uses highly precise dual-component piezoelectric quartz load sensors combined with a single digital rotation encoder that measure longitudinal, transversal, and shear effects for multi-directional force unbalance detection. These piezoelectric force sensors are very sensitive and offer long-term stability and freedom from fatigue for a service life that is virtually unlimited. The high rigidity quartz crystal sensors result in very high frequency detection in all three directions of measurement.
Precision DataWand™ and inner data set arm allow you to quickly and automatically enter all wheel parameter settings in less than three seconds. Automatic rolling wheel parameter setting saves valuable time and minimizes errors. Manual or automatic start when hood is lowered, plus self-calibration function for consistent accuracy.
Belt drive system features a serpentine poly-V belt with a polyester-aramid fiber composite core to resist degradation under extreme operating conditions. The poly-V belt mates perfectly with the 1.5 HP motor and spindle sheave for continuous tension and distribution. Low RPM balancing speed (180 RPM) and rapid six-second cycle time maximize productivity. Automatic/electronic wheel braking secures the wheel at precisely 12 o'clock for easier servicing and proper weight placement.
Tiered weight placement indicators help identify out-of-sight position weight placement such as split-weight or hidden "behind-the-spoke" techniques. LED inner wheel target light automatically illuminates the interior of the rim to help identify the exact weight placement location — auto-activates each time the wheel restraint pedal is depressed.
Quick and precise set-up: Multi-size center cones and a full rubber perimeter no-mar "Quick-Nut" bell adapter make mounting wheels fast and easy while minimizing the risk of costly wheel damage. The precision-machined, hardened-steel 36-mm shaft (ACME thread 30-degree 3-P) and quick-release hub nut dramatically reduce set-up times.
Mounting Cone Package: Includes 3 standard automotive/light truck cones and 1 heavy-duty truck cone. The well-equipped tooling package covers a wide range of wheel sizes and styles. Side cone storage pegs keep mounting cones readily available.
Weight optimization automatically calculates the minimum amount of weight needed to achieve an optimal balance, so you use less weight — which adds up to real savings and increases your bottom line. Gram/ounce selection and millimeter/inch selection offer flexibility for any shop. Balancing increments available in 0.25 or 0.01 oz for precise adjustments.
High-volume top weight tray and side shelf storage give you room to inventory a wide variety of wheel weights and tools. Open-sided hood design allows for a broader coverage of tire shapes and sizes. Wheel graphic interface on the touch-pad display panel features tire and wheel assembly graphics to help simplify speed entry of wheel data and guide technicians through balancing procedures.
Wheel Weight Starter Kit Included: Free samples of Ranger steel wheel weights come with your purchase — one bulk roll of 100 silver adhesive steel tape weights, one bulk roll of 100 black adhesive steel tape weights, and one starter box of mixed clip-on steel weights. Get started balancing immediately with no additional cost.
