The Bilstein B6 24-268929 is a rear shock absorber for the 2009-2015 Honda Pilot, meant to replace a worn factory damper on the rear axle. Owners on user forums who have fitted it describe a firmer, more settled rear end than stock. For a buyer weighing a cheaper replacement, that feedback is the main reason to pay more. Owners also say the stiffer feel is a deliberate change, not a flaw. Confirm the quantity per order before buying, because it has not been confirmed with the manufacturer.
Owners who reported on user forums describe the shocks as holding up well. One owner reported about 12,000 miles with no leaks and no change in feel. Another said the rear end, which had been bouncing and feeling nervous, became stable after the swap. These are owner experiences rather than manufacturer test data, so treat them as real-world context. Searchers looking for a 2009-2015 Pilot rear shock upgrade, a fix for a bouncy rear end, or a Bilstein B6 Pilot rear shock replacement will find the same questions answered in owner threads.
Owners on user forums commonly advise replacing both rear shocks together, since the opposite side usually has similar wear. One owner noted that the factory guidance is to replace them in pairs.
Owners quoting the factory service manual on user forums give 33 lb-ft for the upper bolt and 47 lb-ft for the lower bolt. Some posts cite slightly higher figures, so verify against the manufacturer's service information before tightening.
Owners on user forums report that some people do the job without removing the wheel. Others removed it to set a jack under the shock and ease the upper mount into place.
This is a driveway job for a mechanic-minded owner. Owners on user forums report about 45 minutes to two hours on the first side, and one reported about 17 minutes per side once the rear was already on jack stands. Plan on 14mm, 17mm, and 22mm sockets, a torque wrench, jack stands, and anti-seize for the lower bolt barrel. Corroded bolts are the usual obstacle, so a penetrating lubricant and time to work them loose help. Owners also advise leaving the upper and lower bolts snug, fitting the lower bolt first so the bushing lines up, and then tightening the uppers. Owners on user forums have reported that a loose lower bolt can cause a clunk, so re-check its torque after the first drive.
