On a GTO, LS1 or LS2 and 2004 or 2006 make no difference to the kit. All four sets of Pontiac GTO coilovers we carry fit 2004 to 2006. The one real choice is between BC Racing's two kits, the full kit and the one marked "Fronts Only."

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.
The same kits cover every GTO year.
Every kit is listed for 2004 to 2006.
No kit name mentions the LS1 or the LS2.
You choose between BC's full kit and its "Fronts Only" kit. KW and Ksport each sell one GTO kit.
BC Racing sells four series for the Pontiac GTO: BR, DS, ER and ZX. Both BC kits, the full kit and the "Fronts Only" kit, list all four. Free shipping on BC Racing kits in the continental US.
Both BC GTO kits come in the same four series.
BC Racing BR coilovers have one knob that sets compression and rebound together over thirty clicks. DS keeps that single knob and adds a digressive piston.
ER is an upright shock with an outside reservoir. Compression and rebound are set separately, 30 clicks each.
ZX is the series BC describes as "most track-tested".

Each makes one GTO kit. To go over them with us, call 1-800-460-9106.
You want a lower stance for street driving and shows.
Keep the drop modest and the ride height even, front and rear.
Set the height for the track, then tune from there.
We carry four kits. Each name below matches its product page.
The 2004 to 2006 GTO has a devoted following, and its owners did have one well-known complaint. It is about the front struts and tires, so check it before you choose a kit and wheels.
NHTSA opened an investigation in 2007 after 69 complaints that the front strut rubbed the inner tire sidewall on 2004 to 2006 GTOs, seven alleging tire failure. Some owners blame worn strut top bushings. Strut to tire space is already tight, so coilover body size, wheel offset and worn mounts all matter.
Before you install: Inspect the inner front sidewalls and strut mounts before the install, and check clearance between the coilover and tire at full lock with your wheels.
MotorWeek described the 2004 GTO as based on GM's Australian market Holden Monaro, built Down Under. It came with all independent suspension.
The engine changed in 2005, but 2004 GTO coilovers fit the later cars too.
No. All four GTO kits here are listed for 2004 to 2006, so the LS1 and LS2 cars use the same kits.
That is how BC names one of its two GTO kits. Call us before you order it and we will confirm exactly what ships.
Both BC GTO kits come in BR, DS, ER and ZX.
BC Racing, KW and Ksport. That is four kits in all, two from BC.
Plan on an alignment once the car is set at its new height. Ask us about anything else your GTO needs.
BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. KW and Ksport each set their own warranty terms.
