Infiniti FX, QX70, EX and QX50 Coilovers

If you are shopping for Infiniti FX coilovers for a 2011 FX35, BC has three FX35 kits that look alike. Two things decide which one fits: RWD or AWD, and whether the car has CDC, which the kit names spell out. We carry twenty-one kits for Infiniti's FX, QX70, EX35 and QX50, and BC Racing has one for every model.

Not sure if your car has CDC? We can check your VIN: 1-800-460-9106.

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.

What decides your kit

Check these three things before buying a coilover kit.

CDC

CDC means electronic shocks. BC names its second-generation FX AWD kits With CDC or Without CDC, and only the With CDC kits also come in DS.

RWD, AWD or FWD

Almost every BC kit here is made for one drive type. The 2019-on QX50 kit is FWD.

FX35, FX37 or FX50

On the second FX, BC makes a separate kit for each engine.

Before you buy: what FX and QX70 owners run into

The FX and its successors are luxury crossovers, and most owners use them that way. Lowered FX35s and FX50s have a following in the stance crowd, but owner reports on suspension problems after the drop are scattered. The one that keeps coming up is worn front lower arms. Also check for CDC before you order.

Worn front lower control arms
FX S50 2003 to 2008, FX S51 and QX70 2009 to 2017

On Infiniti Scene, first-gen FX owners report a metallic clunk under acceleration from worn lower arm bushings, which are not serviceable, so the whole arm is replaced. Later FX35 and QX70 owners report arms replaced for worn built-in ball joints. A worn lower arm keeps clunking after coilovers and changes the alignment.

Before you install: Check the front lower arm bushings and ball joints for play before the install, and replace worn arms before the alignment.

Questions about Infiniti FX coilovers, CDC and the QX50

What is CDC, and why does it change the kit?

CDC means electronic shocks. It shows up in BC's kit names as "With CDC" or "Without CDC." BC lists With CDC and Without CDC AWD kits for the second FX35 and FX37. On the FX50, the Without CDC kit is named FX50 and the With CDC kit FX50s. DS comes only on the With CDC kits. If you are not sure which your car has, call us with the VIN.

Which kits cover a QX70 with CDC?

None that we carry. BC's QX70 AWD kit is named "Without CDC," and its RWD kit does not mention CDC. Ksport's S51 kit does not mention CDC, so call us before ordering.

What does "Swift Front Only" mean on the FX kits?

It is part of BC's kit name on every second-generation FX and QX70 kit. It means the optional Swift spring upgrade is offered for the front springs only on that kit. Call us and we will go over what ships in the box.

Is there a kit for the EX35 or the QX50?

Yes. BC lists RWD and AWD kits for the EX35 and for the J50 QX50, plus an FWD kit for the 2019 to 2025 QX50. Ksport lists a 2019 QX50 AWD kit.

Which BC Racing series come on these Infinitis?

BC Racing BR coilovers come on every BC kit here. DS is added on the With CDC kits and the first FX, and RM only on the first FX.

Do BC kits for the FX carry a warranty?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. Ksport publishes its own.
