// THE FULL RUNDOWN

The unsurpassed braking capacity of the Forged Narrow Superlite 4R four-piston caliper serves as the base of this 12.19" big rotor kit for these popular 84-89 Jeep YJ model vehicles (including Cherokee, Comanche, Wrangler and Wagoneer). Kits also can be fitted to select 1990 to 2006 YJ & TJ vehicles if retrofitted to the earlier 84-89 YJ spindle and hub assembly. FNSL4 kits are engineered application specific for simplified installation and full compatibility with OE master cylinder output and ABS functions where used. Big brake kits provide increased brake capacity and complimentary style with wheel, tire, and suspension upgrades. Optional caliper finishes and rotor designs simplify personalizing the style and braking requirements of any application.

// COVERED WHEN IT COUNTS

THIS PART //

Backed by the full Wilwood manufacturer warranty. JAP is an authorized dealer — your warranty is valid from day one.

FULL MANUFACTURER WARRANTY

Every part ships new in the box with the manufacturer's standard warranty — terms and duration vary by brand (typically 1 year to limited lifetime on hard parts). We only sell through authorized channels, so coverage is never voided by gray-market sourcing.

WE RUN THE CLAIM WITH YOU

Warranty issue? Don't fight the manufacturer's phone tree alone. Hit our team with your order number and photos — we open the claim with the brand and stay on it until it's resolved.

WHAT WARRANTY DOESN'T COVER

Defects in materials and workmanship are covered. Trail damage, improper installation, modification, and normal wear items (bushings, pads, wear plates) generally are not — that's standard across every brand we carry.

SEPARATE FROM RETURNS

Warranty claims (defects after use) and returns (unused parts within 30 days) are different lanes. Not sure which applies? Message us first — we'll route it the fast way.
