Last Viper generation
Code: Not in the kit names
Good to know: Only BC makes a kit for these years: a Viper RWD kit named "Extreme by Default", in BR or DS.
Dodge Viper, Durango and Avenger Coilovers
If you own a Viper, you know which body it is: RT/10 roadster or GTS coupe. Kit names for Dodge Viper coilovers go by years and, on KW's two kits, the rear shock mount. BC has a kit for each run of Viper years. This page also covers the Durango and the Avenger: eight kits in all.
Not sure if your Viper has eye or fork rear shock mounts? Call 1-800-460-9106.
RT/10 and GTS
Dodge Viper
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.
Viper by years, then Durango and Avenger
How to tell Viper kits apart
Check the years first, then the rear shock mount.
Years
BC has separate kits for 1992 to 1995, 1996 to 2002, 2003 to 2010 and 2013 to 2017.
Rear shock mount
KW kits say "rear eye mounts" or "rear fork mounts".
Body
KW's later kit names the GTS; its earlier kit does not.

Before you buy: what Viper and Durango owners run into
What Viper and Durango owners report most often, from owner forums, recalls and service bulletins, and what each point means for your coilovers.
Two-mode adaptive dampers on the GTS
Fifth-gen Viper GTS, 2013 to 2017
Edmunds describes the 2013 GTS's two-mode dampers with remote reservoirs, switchable between Race and Normal, that change to Race automatically above 90 mph. On the Viper Club of America forum, owners note the base SRT lacks these adaptive dampers. Swapping a GTS to coilovers removes the factory Race and Normal damper modes.
Before you install: Confirm whether your Gen V is a GTS with adaptive dampers and ask us how the kit handles the damper wiring before ordering.
Rear load leveling on towing Durangos
Durango, 2011 to 2023, with Trailer Tow Group IV
On DodgeForum, third-gen Durango owners say the Trailer Tow Group IV package adds rear load leveling through self-leveling shocks, not an air compressor. A towing guide describes the same mechanical load-leveling rear shocks. Coilovers replace those leveling shocks, so a Durango that tows heavy loads loses its rear self-leveling.
Before you install: Check whether your Durango has the tow package, and talk to us about spring rates if you tow or carry heavy loads.
