Racewill Front Braided Stainless Extended Brake Lines for Lifted Silverado & Sierra — 5–7.5" Lift, Firmer Pedal

Racewill Front Brake Lines 89370 are braided stainless steel extended brake hoses engineered to replace OEM lines and deliver firmer, more responsive braking for lifted 2007–2019 Chevy Silverado and 2011–2019 GMC Sierra models.

If you’ve raised your truck’s suspension and need reliable hydraulic lines that resist abrasion, corrosion, and expansion under pressure, these extended front brake lines are built for that purpose. They pair a corrosion-resistant stainless inner core with a braided exterior to protect against rocks, mud, and trail impacts while maintaining consistent pedal feel. Designed specifically to match popular Silverado and Sierra model years and caliper types, they’re a direct-replacement option for many lifted trucks — with a note about fitment and possible end-fitting modification on certain caliper variants.

Which truck models and years will these Racewill brake lines fit?

These front braided lines are manufactured to fit a range of Chevrolet and GMC full-size pickups across specified model years. They cover most Silverado 1500 versions from 2007 to 2019 and Silverado/GMC 2500/3500HD from 2011 to 2019, as well as GMC Sierra 1500 from 2007 to 2019.

• Compatible: Chevy Silverado 1500 (2007–2019).
• Compatible: Chevy Silverado 2500/3500HD and GMC Sierra 2500/3500HD (2011–2019).
• Compatible: GMC Sierra 1500 (2007–2019).
• Not compatible: 2007 Silverado/Sierra 1500 New Body Style.

How do these extended lines improve braking on lifted trucks?

Extended braided lines prevent the hose body from ballooning when hydraulic pressure rises, preserving pedal firmness and brake response. The stainless core resists internal wear while the woven exterior resists external damage, so braking performance stays consistent on-road and off-road.

• Reduced expansion under pressure for firmer pedal feel.
• Stainless construction resists corrosion for long service life.
• Braided sheath shields lines from stones and trail debris.
• Extended length accommodates 5–7.5" suspension lifts without tension.

Are there installation requirements or fitment caveats I should know?

These lines are intended for trucks lifted between 5 and 7.5 inches and replace part number 89370. Because brake caliper fittings vary between certain vehicle configurations, you may need to modify the hose end or use a compatible adapter to match your caliper’s banjo or threaded port.

• Designed to replace OEM part 89370 on compatible models.
• Best for suspension lifts of 5–7.5 inches; check routing against your suspension travel.
• Some caliper types may require end-fitting modification or an adapter.
• Follow torque specs and bleed brakes after installation for safety.

What materials and protections do these lines use to withstand off-road conditions?

The Racewill hoses combine a smooth stainless inner core with an outer braided stainless steel jacket that resists abrasion and impacts. This layered construction limits internal wear and helps prevent moisture and road salts from corroding the line, extending service intervals compared with rubber hoses.

• Inner stainless core for reduced internal wear and pressure stability.
• Braided outer jacket protects against cuts, rocks, and mud.
• Corrosion-resistant finish for better longevity in wet climates.
• Durable fittings designed for secure hydraulic connections.

Who is this for: These Racewill extended braided front brake lines are aimed at truck owners who have lifted their Silverado or Sierra within the specified model years and need a durable, performance-oriented replacement for stretched OEM hoses. They suit off-road enthusiasts, weekend trail riders, and anyone seeking firmer brake feel and greater protection for brake plumbing when running a 5–7.5 inch suspension lift. If you drive one of the listed models but run a different caliper type, be prepared to adapt the hose end or consult a mechanic for fitment verification.
