Verify five-lug axles and the 3.25-inch offset. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems along with calipers, rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications each call for components matched to the overall braking arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePiston material: Stainless\u003c\/li\u003e\n\u003cli\u003eHydraulic caliper inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor dimensions and construction: 14.00 × 1.10 inches; Spec-37 Iron; GT Slotted\u003c\/li\u003e\n\u003cli\u003eWheel-size reference: 18 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eAxle mounting interface: 88-98 C1500; measured axle offset 3.25 in\u003c\/li\u003e\n\u003cli\u003eRotor \/ hat axle-flange drilling: 5 x 5.00 inches; this does not change the retained hub or axle wheel pattern\u003c\/li\u003e\n\u003cli\u003eHydraulic flexlines: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eMounting hardware: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eNot included: spindles, wheel hubs, master cylinder or brake booster\u003c\/li\u003e\n\u003cli\u003eParking system: Internal shoe parking brake; cable connection must be configured for the vehicle\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 140-17673\u003c\/li\u003e\n\u003cli\u003eBrake assembly: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eCalipers: AERO4; 4 pistons per caliper; Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eCaliper mounting: Radial\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eApplies to the listed 1988–1998 Chevrolet and GMC C1500 Pickup five-lug, two-wheel-drive axle configurations with a measured 3.25-inch offset. The table below distinguishes the early front-brake\/chassis options and later five-lug versions; an Iron ProSpindle entry does not replace the rear-axle checks. Compare axle-flange registration, housing ends and wheel clearance before ordering. The factory parking cable must be modified using the included cable-end adapter kit. Hydraulic flexlines are separate, and the original rubber hoses do not adapt directly to these calipers.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17673\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1576.pdf\"\u003eWilwood installation and compatibility information\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eAxle measurement worksheet\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitFitmentApp.aspx?minorcat=AERO4%20Big%20Brake%20Rear%20Parking%20Brake%20Kit\u0026amp;flange=88-98%20C1500%20-%20Rear%20Kit\u0026amp;offset=3.25\u0026amp;fitment=GTR08\"\u003eWilwood installation and compatibility information\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003ePMB Performance brings over 20 years of parts and fitment experience to component selection.
