Performance + durability of a race part.
Manners + longevity of a stock part.
The best of both worlds.
Over the past 15+ years of building and breaking Toyotas, we have experienced a lot of different rear arm kits. There were lots of options on the market, but there just wasn’t anything that checked off all the boxes. So we decided to design our own arrange of arms, using overkill steel tube, top quality machining, and the industry’s gold-standard Johnny Joints®.
Thick-walled DOM steel:
- No more breaking and bending rear arms! 1.625in tube lowers and uppers.
- Powdercoated textured black with etched-in OPT logo.
Adjustable, offset design:
- Correct your pinion angle to prevent premature u-joint wear and vibrations (if you have a lift then this applies to you).
- Move rear axle position for easier tire clearance.
- Upper
