997 Porsche 911 Nose Lift Kit: KW HLS Install Guide

If you have lowered your 997 Porsche 911, you already know the pain: every steep driveway, parking ramp, and speed bump becomes a front-lip lottery. A 997 Porsche 911 front lift solves that problem for good. The KW HLS (Hydraulic Lift System) hydraulically raises the front axle up to 45 mm — roughly 1.8 inches — at the press of a button, then drops it back down automatically once you are moving. This guide covers what the KW HLS is, why a lowered 997 (Carrera, Carrera S, GT3, and GT3 RS, 2005–2012) needs one, exactly how it installs, and how it compares to the other suspension options in our Tampa, FL shop.

What Is the KW HLS (Hydraulic Lift System)?

The KW HLS is a hydraulic front-lift system that raises a lowered car’s ride height on demand without changing how it drives. Engineered and manufactured in Germany by KW automotive, it adds a corrosion-resistant, coated-aluminum hydraulic cylinder to each front coilover, plus an electric pump, a fluid reservoir, and an in-cabin LED control switch. Press the button and the nose rises; press it again (or simply drive off) and the car settles back to your set ride height. Because the cylinder only extends when you ask it to, the coilover’s normal damping and travel are untouched the rest of the time.

The HLS comes in two configurations. HLS 2 lifts the front axle only — the setup most 997 owners want, since the front lip and splitter are what scrape first. HLS 4 adds cylinders to the rear as well, raising the entire car by up to 45 mm in about 4–5 seconds. Both versions are designed to work alongside a KW coilover kit.

Why Every Lowered 997 Porsche 911 Needs a Front Lift

A lowered 997 loses front ground clearance exactly where it matters most, and a front lift buys that clearance back without giving up the stance. Factory 997 Carrera models already sit low; drop them another 25–40 mm on lowering springs or coilovers and the front lip can hang just 3–4 inches off the pavement. That is enough to catch a driveway apron, a parking-garage ramp, a speed bump, or a raised crosswalk — and on a 997 the front bumper, lip, and (on GT3/GT3 RS cars) the front splitter are expensive pieces of bodywork to replace.

The KW HLS lets you keep an aggressive ride height for the road while adding up to 45 mm of front clearance whenever you need it. At NLP Performance we see the same story from Tampa 997 owners: they love the lowered look but are tired of approaching every incline at an angle. A hydraulic nose lift is the fix. It also protects resale — a scraped or cracked front lip is one of the first things a 997 buyer inspects.

How the KW HLS Works on a 997 911

The KW HLS works by placing a hydraulic cylinder on the coilover body between the lower spring perch and the spring, so the extended cylinder never gets compressed while driving — meaning no unwanted suspension movement and no change to ride quality. When you press the LED control button in the cabin, the electric pump feeds fluid to the front cylinders and the nose rises up to 45 mm. Press it again and the fluid returns to the reservoir, dropping the car to your set height.

Two details make it genuinely usable day to day. First, you can raise or lower the car while moving at speeds up to 50 mph (80 km/h), and the system automatically lowers the car as you drive away — so you cannot forget to drop it. Second, because the mechanical advantage of the cylinder means there is no compression of the extended unit during normal driving, KW’s stated goal is met: driving dynamics are not affected. You get the handling of a proper KW coilover with a garage-door-clearing party trick built in.

How to Install the KW HLS on a 997 911: Step by Step

Installing the KW HLS is a full-day suspension job that we recommend leaving to a qualified shop, because it combines coilover work, hydraulic-line routing, wiring, and a mandatory alignment. Here is the process from start to finish so you know exactly what the install involves.

1. Prep and lift the car

Read KW’s instructions in full, gather metric tools and a spring compressor, and put the 997 on a lift or jack stands. Remove the front wheels and support the car so the front suspension hangs free.

2. Remove the factory front struts

Disconnect the sway-bar end links, brake-line brackets, and any ride-height or wear sensors, then unbolt and remove the existing front strut assemblies. This is also the ideal time to inspect top mounts and control-arm bushings.

3. Fit the HLS front coilovers

Install the HLS-equipped front coilover units. The hydraulic cylinder sits on the strut body between the lower spring perch and the spring, so the damper’s normal travel is unchanged. Torque the strut mounts and knuckle bolts to Porsche’s specifications.

4. Mount the pump and route the lines

Locate the electric pump and fluid reservoir in the front trunk, away from heat and where they stay serviceable. Route the hydraulic lines to each front cylinder along factory-style paths and secure them with the supplied clamps and ties so nothing rubs or pinches.

5. Wire the cabin control

Connect the LED control switch to a switched power source and mount it within easy reach of the driver, or set up the optional remote. Clean wiring here keeps the system reliable and factory-looking.

6. Bleed, set height, and align

Fill and bleed the hydraulic system per KW’s procedure, cycling the lift up and down to purge any air. Set your baseline corner ride height, corner-balance the car, then get a professional four-wheel alignment — a 997 must be re-aligned after any suspension change. Finally, test the lift from the cabin and confirm it rises to full height and lowers cleanly.

KW HLS vs Other 997 Suspension Options

The KW HLS is the only option here that raises the nose on demand; the alternatives lower the car but leave you managing clearance yourself. If your priority is a lowered 997 that never scrapes, the HLS stands alone. If you simply want a tasteful drop and better body control on a smaller budget, a coilover or spring kit may be the smarter buy. Here is how the leading 997 suspension options in our catalog stack up.

HLS 2 vs HLS 4: Which Do You Need?

Choose HLS 2 if the front of your 997 is what scrapes, and HLS 4 if you also need the rear to rise. On the vast majority of lowered Carrera, Carrera S, and GT3 cars, the front lip and splitter make first contact, so the front-axle HLS 2 solves the real-world problem for less money and less plumbing. HLS 4 adds rear cylinders and raises the whole car up to 45 mm in about 4–5 seconds — useful if you run an aggressive rear ride height, load the car heavily, or regularly cross steep crests where the rear diffuser or exhaust can catch.

Either way, the HLS is built to pair with a KW coilover kit, so plan the two together.
