Can anybody tell me what series of Bilseins are on the TRD Off Road package?

Have been in a SR5 TRD Off Road for about a week now and am generally happy with it (besides the lack of front end tow hooks; somebody might oughta get fired over that little bit of idiocy), I'm curious as to what series of Bilsteins are on that package. Trying to decide what upgrades (besides a chrome delete) might be worthwhile, and what can wait until stuff wears out.

Hey @DRvad21 here's some info on the different suspension setups in the Tundra that might help. What suspension changes are you considering?


TRD Sport
Available only on SR5 models—RWD or 4WD—the TRD Sport package fits unique single-rate coil springs all around to lower the truck by 0.5 inch. The base suspension's Tokico twin-tube shocks are replaced by Bilstein monotubes tuned to optimize body control in dynamic maneuvers on pavement. So don't pick this variant if the "sport" you're interested in involves Baja running. The SR5 TRD Sport gets 265/60 tires on 8.0-by-20-inch wheels but shares its anti-roll bars with all other Tundras, save the TRD Pro.

TRD Off-Road
SR5, Limited, and 1794 models can be optimized for more aggressive trail running by ordering the TRD Off-Road package. Like the TRD Sport, it gets Bilstein monotube shocks with a larger 1.8-inch diameter (as compared with 1.3 inches on the twin-tube shocks) that allows them to flow much more fluid during the sharpest impacts while remaining cooler, even without external reservoirs. They are tuned to prioritize keeping the body level during high-speed off-road running.

Pursuant to that same goal, the front coil springs are upgraded to a dual-rate design that stiffens up about 30 percent in the last 30 percent of front suspension travel to prevent bottoming out. In keeping with Toyota's pre-runner tradition, the TRD Off-Road package can be ordered on rear-drive SR5 or Limited models. The package also comes bundled with Multi-Terrain Select (MTS) when ordered on 4WD models. This includes Crawl Control (a sort of off-road cruise control) and Downhill Assist Control. All TRD Off-Road models also get badging, skidplates, mud guards, and a TRD leather-wrapped shift knob.

Adaptive Variable Suspension
Customers desiring the creamiest, best-controlled on-road ride will want to order a Platinum or 1794 model equipped with the optional Advance package. This includes the load-leveling rear air suspension, adaptive dampers, and a 10.0-inch color head-up display. The damping system is akin to those of the same name used on Lexus products and on the Toyota Avalon sedan. It features dampers developed by Hitachi and Aisin that feature solenoid-controlled valves that vary the damping by moving a piston in and out to change the size of orifices the shock absorber oil flows through. Damping can be revised as fast as every 20 milliseconds in response to myriad sensors, including several monitoring g forces at each corner.

TRD Pro
At the top of the lineup is the off-road-optimized Tundra TRD Pro, a stand-alone model variant that gets unique, red-painted dual-rate front coil-over springs that raise the front of the truck 1.1 inches to provide even more travel before the springs stiffen up in the last inches of jounce. The shocks get a major upgrade to Fox internal-bypass remote-reservoir units with 2.5-inch-diameter monotube bodies. These big shocks stay way cooler when storming through the desert. The most visible suspension upgrade is a big hollow front anti-roll bar, also painted red, that's about 20 percent stiffer than the standard solid bar.

Knobby P285/65 (33-inch tall) Falken Wildpeak all-terrain tires are wrapped around 8.0-by-18-inch forged black BBS wheels that increase the front and rear tracks by an inch. Be aware that modified steering rack stops required for the bigger tires add almost a foot to the TRD Pro's curb-to-curb turning circle diameter (now 49.8 feet), and fender flares to cover the rubber widen the body by 1.4 inches, to 81.6 total. (That's not enough to require clearance lights, but Toyota includes them anyway to emulate Raptors and TRXs.) There's a big aluminum front skidplate plus "Xply Armor" high-strength protection for the engine, fuel tank, and transfer case.

Wow thank you for that information
