Ranger Light & Medium Truck Set: rubber-banded flange plates, and why chatter is a mounting problem A brake lathe does not usually produce a poor finish because the tool is dull. It produces one because the rotor is vibrating — harmonic chatter set up between the disc, the adapter and the arbor, printed into the surface as a fine wave the pad will feel for the life of the brake job. Ranger's answer on this three-piece set is a patented detail: neoprene rubber-banded flange plates. The rubber band damps the harmonic before it can build, and the plates themselves are deliberately high-mass, because mass is the other half of the same fix. That is the whole reason to buy this set rather than run the drums and rotors you already can. It extends an RL-8500 or RL-8500XLT bench lathe onto light and medium truck work, and it does it while making the finish better rather than merely making the mount possible. Will It Fit Your Lathe? Machines: the set is built for the Ranger RL-8500 and RL-8500XLT combination disc and drum brake lathes. If your bench lathe is a different make or model, ask us before ordering — adapter sets are not interchangeable across lathe families, and a plate that does not seat squarely on the arbor is worse than no plate at all. Arbor: the rubber-banded flange plate design is intended for the 1" arbor lathes these machines use. Work it covers: hubless cast and composite light-truck rotors, drums and most flywheels — which between them account for most of the automotive rotors and drums a general shop sees in a week, including light-duty trucks. Fitment against your particular lathe and your particular rotors is ultimately the shop's call. If you have an unusual application, describe it to us and we will check it against Ranger's data before you order. Single setup, self-centring, and the time that actually costs you The interesting economics of brake lathe work are not in the cutting, they are in the setup. Every time a technician swaps adapters, re-centres a rotor, takes a scratch cut and re-checks runout, the job absorbs minutes that never appear on a quote. These adapters are self-centring and designed for a single setup — the rotor goes on, it is concentric, and the cut can be a single pass rather than a rough-and-finish pair. Getting to single-pass work matters most at the top of the size range. Large drums, large rotors and flywheels are exactly the parts where a marginal mount turns into chatter, and where a second corrective pass costs the most metal from a part that only has so much thickness to give. What this replaces Old bell adapters are the alternative, and they are the reason many shops quietly stopped machining anything larger than a car rotor. They mount off a face that was never meant to locate the part precisely, they add nothing to the system's mass, and they wander as they wear. A shop running them ends up with results that vary by operator. This set is intended to retire them: better location, more mass, a damped mount, and a fixture that is easier and safer to handle than a stack of bells. Then there is the commercial argument. A rotor that can be machined to a clean micro-finish is a rotor the customer does not have to buy, and the ability to save one on a light truck — where the parts are considerably more expensive than a passenger car's — is what pays for a set like this. Machining is also what manufacturers increasingly expect as service standards tighten. Perfect For General repair shops already running a Ranger bench lathe and turning away truck brake work for lack of adapters. Fleet workshops where the same light and medium trucks come back on a schedule and machining beats replacing. Brake and undercar specialists who are judged on surface finish and want the mount to stop being the variable. Machine shops handling flywheels alongside brake work. What's in the Box A three-piece kit: the set of light and medium truck adapters, with the neoprene rubber-banded flange plates that give it its damping. Ranger's data does not list tooling, bits or an arbor as part of this set, so assume your lathe's own standard tooling continues to do the cutting. Specifications Fits Ranger RL-8500 and RL-8500XLT brake lathes Kit contents 3-piece adapter set Plate design Neoprene rubber-banded flange plates, high mass, self-centring Arbor Suited to 1" arbor lathes Applications Hubless cast and composite rotors, drums, most flywheels; cars and light trucks Shipping weight 27 lbs. (12 kg) Shipping dimensions 8" x 8" x 5" (203 mm x 203 mm x 127 mm) The shipping weight is worth a second look: 27 lbs. for three adapter plates is the mass argument made physical. Light adapters are cheap to ship and poor at damping. Certification and documentation This is lathe tooling rather than a lifting or pressure device, so no independent safety listing applies to it and our data does not claim one. Ranger publishes a specification sheet and a warranty document for the set, both linked on this page. If your shop's quality system requires documented tooling compatibility before something goes into service, ask us and we will get the fitment confirmation from Ranger in writing. Shipping and delivery This item ships free within the lower 48 states, so there is nothing to add at checkout. Residential delivery carries a residential fee, which is shown to you before payment. If it is easier, collect from the pickup locations listed further down this page. Check the carton at delivery rather than afterwards. Damage noted on the carrier's paperwork before you sign is straightforward for us to resolve; damage discovered after a clean signature is not. A photograph and a same-day message is all we need to start. Warranty Ranger's warranty document covering this set is linked on this page and is the authority on any claim. One practical note: do not modify a flange plate to make an unusual part fit. Machining, drilling or grinding an adapter destroys both the concentricity it was built to hold and any coverage on it — and an adapter that no longer runs true will quietly ruin every rotor it touches. If you have a part that will not mount, call, text or chat with us and we will find out whether the right fixture exists.
