Lifting a truck changes the geometry of the suspension, and stock brake lines often become too short, leading to dangerous tension or rupture. Extended brake lines restore proper length and reduce the risk of line failure during articulation. We researched manufacturer specifications, industry safety standards (DOT, SAE), and aggregated owner feedback to compare the top options. Our evaluation focuses on construction quality, fitment, and real-world durability to help you choose the right lines for your lift height and driving conditions.
Below are our picks, ranging from budget-friendly rubber hoses to premium stainless steel braided lines. Each product is scored based on performance, durability, value, ease of installation, and safety. We also note who should consider an alternative.

1. Crown Performance 930 Series Stainless Steel Extended Brake Lines: Best Overall
Crown Performance’s 930 Series are among the most respected extended brake lines for lifted trucks. They feature a PTFE (Teflon) inner liner surrounded by a stainless steel braid and a clear PVC abrasion jacket. Based on owner feedback and the spec sheets, these lines provide a firm, consistent pedal feel even under heavy braking. The PTFE liner resists moisture absorption and brake fluid degradation, which contributes to long service life. In our evaluation, the build quality and attention to detail (laser-etched fittings, pre-installed banjo bolts) make installation straightforward for a DIYer with basic mechanical skills.
However, these lines are more expensive than rubber hoses. If you are on a tight budget or drive a truck with a mild lift (under 3 inches) where rubber lines would suffice, the Crown Performance lines may be overkill. Also, some owners report that the clear PVC jacket can yellow over time, but this does not affect performance. These are best for lifted trucks used off-road or for towing where maximum brake line reliability is required.
- PTFE inner liner resists corrosion and swelling
- Heavy-duty stainless steel braid with clear PVC cover
- Direct bolt-on fitment for popular lifted trucks
Pros: Excellent pedal feel and pressure consistency; Comes with all necessary hardware and banjo bolts
Cons: Higher cost than rubber alternatives
2. Power Stop K7102 Extended Brake Lines: Runner Up
Power Stop is a well-known brand in the brake industry, and their K7102 extended brake lines are a solid choice for lifted trucks up to 4 inches. They are constructed with stainless steel braid over a rubber inner hose, offering improved durability over stock rubber lines. Based on owner feedback, the lines are easy to install and the included brackets ensure proper routing. The DOT approval and high-pressure testing give confidence in their safety. For the price, these lines deliver a noticeable improvement in pedal feel and longevity compared to stock.
The main limitation is the lift height range: they are designed for lifts up to 4 inches. If your truck has a taller lift, you will need longer lines. Additionally, the rubber inner hose may degrade faster than PTFE lines if exposed to moisture or extreme temperatures. These are a great choice for moderate lifts and drivers who want a reliable upgrade without spending a premium.
- Designed for 0-4 inch lift heights
- Includes mounting brackets and hardware
- DOT approved and evaluated to 3000 psi
Pros: Good value for a complete kit; Easy bolt-on installation with clear instructions
Cons: Not suitable for lifts over 4 inches
3. Rough Country 927 Extended Brake Lines: Best for Off-Road
Rough Country’s extended brake lines are a popular choice among off-road enthusiasts for lifts between 4 and 6 inches. They feature a rubber inner hose with a braided outer layer for added strength. In our research, owner feedback indicates these lines are durable enough for moderate off-road use and provide adequate pedal feel. The kit includes brackets and hardware, making installation straightforward. For the price, they are a good value for those who need extra length without the cost of stainless steel lines.
However, rubber lines are more prone to swelling and degradation over time compared to PTFE-lined lines, especially if exposed to moisture or harsh chemicals. Some users report a softer pedal feel after extended use. If you frequently drive in wet or muddy conditions or demand maximum performance, consider a stainless steel PTFE option. These are best for budget-conscious owners with moderate off-road needs.
- Designed for 4-6 inch lifts
- Rubber hose with braided outer layer
- Pre-assembled with fittings and brackets
Pros: Affordable option for taller lifts; Includes all necessary hardware
Cons: Rubber construction may swell over time
4. Skyjacker FBJS06 Extended Brake Lines: Best for Heavy Duty
Skyjacker’s FBJS06 extended brake lines are built for trucks with 6-8 inches of lift. They feature a stainless steel braided exterior over a rubber hose, with heavy-duty zinc-plated fittings. Based on the spec sheets, these lines are designed to withstand the demands of extreme off-road use and large tires. Owner feedback highlights their durability and ability to handle articulation without binding. The length is generous, ensuring plenty of slack for suspension travel.
On the downside, the rubber inner hose is still prone to swelling over time, and the fittings can be tight in some applications, requiring careful routing. Additionally, they are priced higher than similar rubber lines. These are best for trucks with tall lifts that see heavy off-road use or towing, but if you want the best possible longevity, a PTFE-lined line may be a better investment.
- Designed for 6-8 inch lifts
- Heavy-duty stainless steel braid
- Zinc-plated fittings resist corrosion
Pros: Very durable for extreme lifts; Long length for tall suspensions
Cons: Installation can be tight on some models
5. EBC Brakes BBK-1 Extended Brake Lines: Premium Choice
EBC Brakes is a premium brand, and their BBK-1 extended brake lines reflect that. They use a PTFE inner liner with a stainless steel braid, offering minimal expansion and consistent brake pressure. In our evaluation, the build quality is top-notch, and the universal design includes multiple fittings to fit various trucks. Owner feedback praises the improved pedal feel, especially under heavy braking. The DOT and TUV approvals add to the safety credentials.
However, these lines are designed for lifts up to 3 inches, which limits their use to mild lifts. They are also among the most expensive options per line. If you have a stock-height or mildly lifted truck and want the best performance, these are excellent. But for taller lifts, you will need a different product. Budget-conscious buyers may find better value elsewhere.
- PTFE inner liner for minimal expansion
- Universal fit with multiple fittings included
- DOT and TUV approved
Pros: Excellent pedal feel and response; High-quality materials and construction
Cons: Expensive for the lift range
6. Bendix BXL-100 Extended Brake Lines: Budget Pick
Bendix BXL-100 extended brake lines are an economy option for trucks with 2-4 inches of lift. They are made from standard rubber hose with crimped fittings. Based on owner feedback, they work fine for light use and provide the needed extra length. The price is very attractive for those on a tight budget. Installation is straightforward, and the kit includes basic hardware.
However, the rubber construction is the weakest point. Over time, moisture can cause swelling, and the hose may crack in extreme temperatures. They are not recommended for off-road use or heavy towing. If you need a temporary solution or drive only on paved roads, these might suffice. But for any serious use, invest in a braided line.
- Affordable rubber construction
- Designed for 2-4 inch lifts
- Includes basic hardware
Pros: Very low price point; Simple installation
Cons: Rubber hose prone to swelling and cracking
7. Dorman 624-700 Extended Brake Lines: Wide Compatibility
Dorman 624-700 extended brake lines are a universal option that fits many trucks with lifts up to 3 inches. They are rubber hoses with standard fittings. In our research, they are best suited for stock-height replacements or very mild lifts. The price is among the lowest, making them accessible. Owner feedback indicates they work as expected for basic needs.
But the rubber hose is not as durable as braided lines, and the length may be insufficient for taller lifts. Some users report a spongy pedal feel. These are only recommended for budget builds or as a temporary fix. If you have a lift over 3 inches or drive aggressively, look elsewhere.
- Universal design fits many trucks
- Affordable rubber hose
- Includes basic fittings
Pros: Wide vehicle coverage; Very low cost
Cons: Short length limits lift height
Frequently Asked Questions
What length extended brake lines do I need for my lifted truck?
Measure the distance from the brake line bracket on the frame to the caliper at full suspension droop (when the wheel is hanging). Add 2-3 inches for slack. Most manufacturers provide length recommendations based on lift height. For lifts up to 4 inches, 16-18 inch lines often work; for 4-6 inches, 20-24 inches; for 6-8 inches, 26-30 inches. Always check the product specifications for your specific lift height.
Are stainless steel braided brake lines worth the extra cost?
Yes, for most lifted trucks. Stainless steel braided lines with PTFE inner liners offer better pedal feel, resist expansion under pressure, and last longer than rubber lines. They are more durable against abrasion and corrosion. If you off-road, tow, or drive aggressively, the extra cost is justified. For street-only driving with a mild lift, quality rubber lines may suffice.
Can I install extended brake lines myself?
Yes, with basic mechanical skills. The process involves raising the vehicle, removing the wheels, disconnecting the old lines, and installing the new ones. You will need to bleed the brake system afterward. Most kits include instructions. However, if you are not comfortable working with brakes, have a professional do it to ensure safety.
Do extended brake lines affect brake performance?
Properly installed extended brake lines restore the correct length and reduce stress on the system. They do not negatively affect performance if the lines are of good quality. In fact, braided lines can improve pedal feel by reducing line expansion. However, excessively long lines may cause a slightly softer pedal due to increased fluid volume.
How often should I replace extended brake lines?
Rubber lines typically need replacement every 3-5 years or if you see cracks, swelling, or leaks. Stainless steel braided lines with PTFE liners can last much longer, often 5-10 years or more, but inspect them annually for abrasion or damage. Replace immediately if any wear is found.
Our Verdict
After researching and comparing the top extended brake lines for lifted trucks, our top pick is the Crown Performance 930 Series for its superior PTFE construction, excellent durability, and consistent pedal feel. It is the best choice for most lifted trucks up to 6 inches. For a more budget-friendly option that still offers good performance, the Power Stop K7102 is a strong runner-up, especially for lifts under 4 inches.
