Coachbuilder Rear Driveline Spacer | 1.25" Thick for 10.5" Rear Axle | Fits Toyota Tundra 2007–2021 | Ekstrom Design

Lift the rear of a 2007–2021 Toyota Tundra far enough and the driveshaft doesn't just run at steeper angles — it starts pulling out of the slip yoke, leaving less spline engagement to carry the load. The Coachbuilder Rear Driveline Spacer fixes that on Tundras with the 10.5” rear axle: a 1.25”-thick disc of CNC-machined T6 6061 billet aluminum bolts between the axle flange and the driveline, extending the driveshaft back into the spline. Where a carrier bearing drop kit corrects the driveshaft's angle at the center bearing, this spacer restores its engagement at the axle — tall builds often need both. Hardware is included, and a hard black anodize finish stands up to everything a rear axle lives in.

If a tall rear lift created the problem, correct the angle side too: pair this spacer with the Carrier Bearing Drop Kit for 5”–6” rear lift, or the +4” Shackle Kit if you're still building the lift itself. A milder .750” version of this spacer is available for setups that need less correction — find both in our driveline components collection along with the rest of the Coachbuilder catalog.
