Product Details

The Wilwood 170-12427 Lug Drive Dynamic Drag Rotor Hat features Wilwood's advanced dynamic rotor mounting system engineered specifically for high-performance drag racing applications. With a 1.71" offset designed for Big Ford and Mopar applications, this hat eliminates traditional rotor bolts entirely, allowing the rotor to float and move independently of the hat as it expands and contracts through heat cycles.

By removing all thermally generated stress from the rotor attachment points, this innovative lug-drive design keeps rotors flatter and running truer under extreme conditions. Brake response and pedal feel remain consistent run after run, while pad knock-back and rotor drag are completely eliminated. The hat itself is protected from thermal distortion and the bolt hole alignment problems that plague conventional fixed-mount designs when swapping new rotors onto a used hat.

Key Features:

  • Boltless Lug Drive System — Rotors float freely, expanding and contracting without transferring thermal stress to the hat
  • Spring-Loaded Stainless Steel Inserts — Replaceable inserts in each lug-drive slot protect the aluminum hat from wear caused by rotor loading under brake torque
  • Single Snap-Ring Retention — One large snap-ring secures the rotor to the hat for fast, tool-free assembly and installation — no torquing or safety wiring of rotor bolts required
  • Lightweight Aluminum Construction — Precision-machined from premium aluminum alloy for high strength with minimal rotating weight
  • Drilled Stainless Rotors Compatible — Designed for use with Wilwood's additionally drilled stainless alloy discs to remove unnecessary rotating mass from the drivetrain
  • 1.71" Hat Offset — Engineered for Big Ford and Mopar hub/axle configurations
  • Eliminates Thermal Distortion Issues — No more bolt hole misalignment when re-installing rotors on a previously used hat

The Wilwood 170-12427 is a direct upgrade for drag racing builds where consistent braking performance, fast rotor changes, and reduced rotating weight are critical. It pairs with Wilwood's Dynamic Drag rotor lineup and is sold individually.

Great Products, Very Cheap, Fast Shipping. Will be a returning Customer. A+++

Good service, great products and quick shipping. I received a good shipping discount using Google payment. Only problem was the item was shipped to my billing address instead of my shipping address.

Excellent experience. Cheapest price I could possibly find, reasonable shipping cost (other people tried to charge upwards of $20 where I was only charged $14). Shipping was VERY quick. <br><br>I was slightly weary of ordering from Autoplicity as I had never heard of them before but from here on out they will be the first place I check. Could not be happier. <br><br>There is nothing that could have made this experience more enjoyable for me.

I'm not the kind of person that orders things online. I called twice and talk to a rep. Extremely friendly and helpful. Totally made me feel secure about placing my order. I researched for a few days to get the best price. Autoplicity by far had the best price. Thank you so much. My son is going to freak out when he gets his Christmas gift. :)

Excellent transaction. Very fast shipping & shipping packaging high quality. Item well protected. Product expected was the product received. Will buy again from Autoplicity.com.
