The CLA, GLA, A-Class and GLB are four compact Mercedes that are easy to mix up, and the kit names say front drive, 4MATIC or both. Whether your car is front drive or 4MATIC, whether it is an AMG, and on the A-Class the type of rear suspension all change which kit fits. All twenty-two sets of Mercedes-Benz CLA, GLA, A-Class and GLB coilovers we carry are below.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.
Each of these three changes which kit fits.
KW's CLA 250 kits differ by drive type. Ksport's GLA kit is FWD only.
KW has separate CLA 45 and CLA 35 kits for cars with and without electronic dampers.
BC's FWD kit fits only cars with the torsion beam rear. The AWD kit is for the multi-link rear. BC makes no kit for an FWD car with the multi-link rear.
BC Racing makes three series for the Mercedes-Benz CLA, GLA, A-Class and GLB: BR, DS and RM. Free shipping on BC Racing kits in the continental US. The GLA 35 kit is the only one that comes in BR only.
These are the BC Racing series we sell for these cars.
BC Racing BR coilovers have one 30-click knob that sets compression and rebound together.
DS has the same knob as BR, plus a digressive piston.
RM uses an upside-down single-tube shock, made for MacPherson struts.
We also carry kits from these brands. Call 1-800-460-9106 and we will compare them with you.
These are the CLA 45 kits to look at.
BC's torsion beam kit is the one that fits.
BC's GLB kit is the one that fits.

The compact Mercedes range is still fairly new to coilovers, and most owners keep the factory setup. The one complaint that shows up widely is not about lowering at all: CLA owners find the stock ride harsh. That is often the reason they look at adjustable coilovers.
Cars.com's review called the 2014 CLA's ride pretty harsh, with regular jolts over road defects, and the CLA45 AMG rougher still. MBWorld owners name the harsh ride as a top complaint, though some accept it for the handling. Damping range matters more than the drop for a better ride.
Before you install: Choose a kit with adjustable damping, start soft, and keep the drop modest on a car you drive every day.
Mercedes-Benz Canada wrote at the launch: "The CLA is set to establish a new segment," describing a compact four-door coupe.
BC makes its FWD A-Class kit only for cars with the torsion beam rear, and its other A-Class kit for AWD cars with the multi-link rear. BC has no kit for a front drive car with the multi-link rear, so check your rear suspension or send us the VIN before ordering.
With KW, yes: the CLA 45 AMG kits depend on whether the car has electronic dampers, and the CLA 250 kits on 2WD or 4Matic. BC's 2014 to 2019 CLA kit names no trim, and Bilstein's B14 names both.
It is the name Bilstein gives one of its GLA250 kits. Call us and we will explain how it differs from the Pro-Kit before you order.
BC makes two: the GLB 4Matic and the GLB 35 AMG, both in BR, DS or RM.
BR, DS and RM. Every BC kit here comes in all three except the GLA 35, which comes in BR only.
BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. The other three brands publish separate terms.
