Description
Product Overview
Your lifted JK's factory front brake lines are the weak link. Stretched at full suspension droop and vulnerable to trail debris, they're a failure waiting to happen. The iFJF Extended Front Stainless Steel Brake Lines (replacing #89707) solve both problems: extended length for proper routing at 4-6 inches of lift, and braided stainless construction that resists rocks, mud, and UV. DOT-approved and individually pressure-tested to 4,000 PSI.
Key Features
-
DOT FMVSS-106 Approved & 4,000 PSI Tested — Each line pressure-tested individually. Street-legal in all 50 states.
-
Extended for 4-6" Lift — Critical extra length so brake lines never bind or stretch at full droop with steering at full lock.
-
Braided Stainless Steel Armor — Protects inner line from sharp rocks, mud, and road salt. Also prevents internal expansion for firmer pedal.
-
PTFE Inner Liner — Teflon core resists brake fluid breakdown and temperature extremes. Consistent pedal feel in all conditions.
-
Direct Replace #89707 — Factory-correct end fittings. Unbolt old rubber line, bolt in new stainless line — done.

Frequently Asked Questions
Q: Sold as pair or individually?
A: Sold as a pair — driver + passenger side front brake lines in one kit.
Q: Need for a 2.5" lift?
A: Factory lines usually have enough slack at 2.5". At 4" and above, they become dangerously tight. We recommend stainless front lines for any lift over 3".
Q: DIY install possible?
A: Yes — if you've done a brake job before. You'll need a line wrench (11mm), basic tools, and bleeding equipment. 1-2 hours plus bleeding.
Q: Compatible with big brake kits?
A: Yes — end fittings match factory hardline connections, so any big brake kit using factory hardlines is compatible.
Q: Re-bleed if only front lines replaced?
A: Yes — any time the hydraulic system is opened, bleed the affected circuit. Front circuit only is faster but don't skip it.
