All Pro sells 2 different leaf packs you might be interested in....
All-Pro Leaf Springs
- provides 3 inches of lift - Used more for flex and offroading conditions. You shouldn't have to worry about sag at all with these...
Improve your Tacoma's suspension performance and gain lift for tire clearance and long travel with All-Pro quality leaf springs! The 2005+ Tacoma 3" lift springs mount in the original spring hangers. They feature a special torque leaf to reduce axle wrap. The 11-leaf pack provides a smooth, progressive spring rate, while extended u-straps and teflon friction pads improve performance. The military wrap at the non-shackle eye provides the durability to take years of punishment. All-Pro leaf springs are sold in pairs, with a complete urethane bushing and sleeve kit. All-Pro backs up their leaf springs with a comprehensive 12-month warranty for non-racing applications and proper installation (with OE spring hangers, shackles and bumpstops).
* NOTE: These springs are NOT designed for extreme weight carrying capability. They are designed for ride quality and flex. For springs designed to carry heavy loads, see the Emu Dakar springs below.
If you tow or haul a lot you might want to look into the Emu Dakar Leaf Springs
they sell. Made to carry more weight but not flex as well
on the trail and provide 2.75 lift.
For heavy, fully-outfitted expedition vehicles and those hauling heavy loads, we recommend Emu Dakar heavy duty leaf springs. These springs feature a heavier spring rate than our All-Pro leafs, plus several other features designed to withstand heavier loads. Emu Dakar leaf packs are flat at the center axle mounting surface, to make installation easier and to relieve any stress to the spring pack that may occur from placing a flat spring perch against the arched portion of the spring. Emu Dakar springs are fully scragged, load tested and shot-peened on the tension side of the spring to ensure long-lasting performance. Teflon pads and graphite coating help to reduce friction within the spring pack, and a millitary wrap at the main spring eye ensures safety. Note that on most "normal", non-heavily-laden vehicles these springs will provide a stiff ride quality and decreased suspension flex. They achieve optimum ride quality and performance under heavier loads.
Either way you go, its still a huge improvement over what your currently running.
Oh and the price for option 1 is 375$ and for 2 its 399$
How heavy is your bumper anyways?
