Return PolicyThese new multi-leaf rear springs by Posies lower your classic Ford half-ton pickup 3" more than a set of stock replacement springs. Super Slide springs incorporate moly-nylon buttons that reside in die-formed pockets at the tips of the spring leave. Replace your 50 year old stock springs with these new, computer-designed leaf springs for a much smoother ride. Springs have reduced load capacity from stock just from the fact that you are lowering your vehicle.
Does not include shackles, shackle bolts, or U-bolts. U-bolts available separately as part number 916-3326.

Great price for Posies springs. Just got them installed & I did get a 3" drop as advertised. Everything went smooth but I decided to reuse my old U-Bolts. Just for the sake of originality and they were in good shape, I did use the Ny-lock nuts that came with the new U-bolts, liked them better than the old ones. My '56 F-100 sits a little better now, but could be a bit lower, maybe a shackle change would be next. Great product!

My '56 F100 was so raked towards the front after installing the Heidt's Mustang II front end. I had the choice of doing the axle flip or install the Posie rear lowering springs. I'm glad I chose the latter, the ride is better, the stance looks better, and the steering is no longer hinky because it was so dropped in the front.
