I finished lowering the rear of my '07 RCSB the other day using an SOS flip kit, I also added a TRD rear sway bar. OEM coils with Bilstein 4600 series shocks up front. Alcan leaf springs with Bilstein 4600 series in the rear. Stock OEM 18" alloys with P255/70R18 Michelin tires (32"). I am running a tail pipe that turns down in front of the axle. Being frugal, we cut the existing tailpipe at an angle as it curved up to go over the axle. We then rotated the new turn down with resonator 180 degrees, and welded it in place. Why keep the resonator?, I prefer a quiet exhaust.

The shake-down run was a mixed bag of driving that included stop-n-go traffic in Atlanta, the U-bolts needed to be re-torqued after the trip as expected but everything else remained nice & tight. I am VERY HAPPY with the results.

Lowering the rear of this Tundra is one of the most
rewarding mods I've performed on the 10 year old truck.

Thank you for allowing me to share my RSCB build here on Tundra Talk, you can probably tell that I am happy with the results and the Tundra in general. I'm going to enjoy the drive for now, but feel free to ask questions about the process & parts used.

Looks awesome, glad it all came together and your happy with it. Badass truck- don’t see many Rscb ever really around here.

Thank you!

They are rare, but there are two others that I see in my area. One is a 2wd super white similar to mine driven by and older lady, the other is a black 4WD driven by a high school kid.

Benefits that I've seen since lowering the rear and adding a rear sway bar:


. The occasional bed bounce & vibration are gone.

. The seating position is more comfortable, I no longer feel like I am being pushed toward the windshield.

. I have a better view from the rear view mirror, I can see more of what is behind me.

. Lane changes & cornering are much more precise, even at higher speeds.

. I didn't give up any ground clearance.

. Launch & acceleration is more efficient than before.

-- It's also much easier for my 80 year old mom to enter & exit the truck.

This is the second time that I have used Alcan for replacement Toyota truck leaf springs, several years ago they built a custom set with a little lift for my '96 4WD T100. Alcan makes some great leaf springs.

Great news! It turns out that the added weight of the Ranch Hand Protestor Bar does not require lifting the front suspension, it sits perfectly level with new OEM coils and Bilstein 4600 series shocks.

resonated turn down

The installation instructions mention the possibility that the new suspension will interfere with your exhaust system, they aren't kidding. My low cost solution involved cutting the tail pipe off at an angle were it curved up to go over the axle, we then rotated it 180 degrees and welded it in place as a resonated turn down. There was a leak at the original connection that had eroded the flange, so we had to weld it up ugly. The end result is totally functional, and it's almost as quiet as with a full length tail pipe.

I put 1200+ miles on the RCSB for Thanksgiving... not a single hick-up, and I averaged 16 to 19 MPG depending on speed. 19 MPG under 75MPH, 16 MPG above 75 MPH (sustained average highway speeds). Press your right foot to the floor while cruising @ 70 mph and the truck comes alive. Right now, the harmonic sweet-spot for this truck the way I have it set up is a little above 80 MPH. Lane changes are exact, but the ride is still a little stiff for huge potholes, ugly expansion joints, and abrupt changes in the surface. On smooth surfaces it's not harsh, and easily controllable... the nannies did there job at least one time that I know of when I touched on the marbles on the outside edge of a downhill sweep to the left. I think the ride will soften a little bit once the new suspension is broken in.

All-in-all, I am satisfied with this old RCSB.

275K and counting.

Just yesterday my friend (father of the bride) and I took the path less traveled on the way home from his daughters wedding in Asheville, NC - US 178 from Rosman, NC south to I-85 in SC. He rides, and he was driving the AWD Subaru like he would ride his motor bike (yanking & banking).

This RCSB handles the hilly-twisty-curvy two lane blacktop at speed with ease, the only problem I experienced was temporarily losing sight of his Subaru Outback directly in front of me as we negotiated the sharp left-hand curves... the huge A pillar in the Tundra is what blocked my view.

Toggling the sequential 6 speed kept me off the brakes, and allowed me to whip through the turns - it was a great roller coaster ride in the rain & fog. We encountered one slower driver, and they pulled over to let us pass - we appreciated their courtesy.
