  • TTFCS2005- ToyTec’s BOSS standard 2.0 front Coilover -designed with a larger 5/8” nitro steel shock shaft which is much more corrosion resistant than chrome plating and is valved specific to your vehicle, improving the overall handling and performance. The threaded Clear-Blue Chromate zinc plated steel shock body is adjustable from 0-3” of front lift height and can be fine tuned to level your truck side to side and front to back. Each shock has a 200 psi gas charge and is dyno’d before it ships. Upper mounts and adjustment rings are machined from 6061-T6 Billet aluminum and are then anodized black to prevent corrosion. TIG welded spanner wrenches are included for easy adjustment.  Comes fully assembled and ready to bolt on for easy install.

    • TT-75110RR – Rear BOSS 2.0 Remote Reservoir Shocks.  For additional performance, the remote reservoir shock will hold more oil to prevent shock fading on rougher applications.

Add Upper Control Arms to complete your kit:

    • Total Chaos Uniball Upper Control arms – 96504 – Maximize your wheel travel and increase your strength while also correcting alignment angles.
    • SPC Adjustable Upper Control Arms – 25480 – The most adjustable UCA on the market.  Correct your alignment angles.  Also great to help with adjusting for tire clearance.

Note:  Boss front coilovers are only designed to work with stock front lower control arms

The difference between the Ultimate & BOSS kits is in the front coilover. The Ultimate kit is assembled with the Bilstein shock and the BOSS kit is assembled with BOSS shock. The BOSS shock is re-buildable and overall is a little softer and smoother than the Ultimate

Tire Information:

Q. What size tires can I run on stock wheels with the 3″ kit?
We have not tested every wheel/tire size on these trucks, but 285/70/17 tires will fit the FJ on stock wheels.

Q. What size tires can I run on a 17×8″ wheel?
With 4″ or 4.5″ back spacing we have several trucks running 285/70/17 tires, but they may rub on the front depending on wheel width, and back spacing. We do not guarantee any tire/ wheel fitment and recommend you have your tire dealer install and “test fit” any wheel tire combination you are considering

    Questions and answers of the customers

    1. A

      We always recommend test fitment before, because rubbing may depend on suspension condition, rims offset and castorcamber adjustment

      We haven't tested this kit with R18, but they may require additional wheel spacers not to rub, because the new Tacomas are already lifted by 1'' from the factory by the cost of losing a 1'' of suspension downtravel.

      Performance kit comes with Front Shock bodies that are 2.5" in diameter providing additional oil over standard OEM shocks. It also come with Rear Remote reservoir shocks.

      Overall you get better performance

      This is a very good option, it was developed by ToyTec and performance wise it is equal if not better than the Ultimate kit.
