This is How a Vehicle Should Handle
Honestly the best purchase i have made for my 2019 tacoma. Handles like a dream, instructions were simple and had all torque specs. Everything else i found on the internet. Recommend the SRQ adjustable sway bar links. Handles like brand new.

Love Me Some BP-51 Kit!
The OME BP-51 HD Lift Kit is rad! Super quick shipping and great customer service (I was bugging them with a ton of questions, lol). Love my lift kit, all high-quality components, pretty easy to install, and rides soooooo much better than stock!

No Comparison in Ride.
Install was the same as any, other than the addition of resi brackets. Adjustment took a few trips but I think I have it all figured. The BP-51 OME setup is far past any radflo, toytec, or bilstein kits I have ran.

The Expert's Opinion

"Old Man Emu continues to earn our respect in a crowded market.

The MT64s ride tight, stay composed under load, and earn  their price point; Jeff's Tundra proved that. The BP-51 is the real standout though: genuine range from plush daily comfort to serious performance, all through the adjustments, in the same shock.

Not content with coasting on their reputation, OME is still building like they have something to prove."
