F150 Rear Sway Bar

Ford nor Chevrolet uses a rear sway bar. Ram is the only truck that I'm aware comes with one from the factory.

Always considered adding one to the 2500HD Silverado, never pulled the trigger.

The F150 in certain situations provides significant notice that a rear sway bar isn't present. Moderate hard acceleration out of a turn with open rear differential results in wheel spin on the inside rear wheel, truck reacts with TC cutting power to prevent the tire spin, and thus defeating the driver intention of moderate hard acceleration. The P series tires don't seem to help. Balance of the truck could be better, in OEM form under-steer is prevalent.

Installed the sway bar per the instructions and the solution seems to work rather well. Truck is much more balanced. Taking corners at speed can now scrub all four tires with balance and gone is the heavy over-steer condition. Bar is set on the softest setting, closest to the front of the vehicle, of the three settings available.

Negatives are two fold, kit needs additional pieces, and end links are the old less desirable design, not the S design pictured in the product ad.

The kit doesn't include washers for the upper end link connection through the clevis bracket. The kit includes a bolt and lock nut for attaching the upper portion of the end link to to the clevis bracket. It should have included a 2 1/2" long bolts versus the 2 1/4" bolts and two washers for each side four total. The bottom connection for the endlinks to the sway bar get washers. Why are the upper connections second class citizens?

The craftsmanship of the endlink appears to the the original version, shaped like an L. There appears to be a newer engineered version of the endlink in a S design (pictured in the Amazon ad). The L design appears to put side loading on the upper and lower endlink bushing. Observed about a 15 degree orientation side loading on the endlinks. The bottom connection of the endlinks appears to be oriented toward the center-line of the truck, Thus inducing the 15 degree inward orientation. Would expect the endlinks bushings when installed to be in a completely vertical orientation.

Wonder about the longevity of the endlinks, moreover the bushings, after thousands of miles being canted with stress of the bar being applied. The geometry and side loading on the endlink bushings could be better.

Good solution, attention to detail with the manufacturing of the endlinks and associated geometry could be improved.
