These BETTER bolts are SAE grade 8 FLANGED 5/8th” O.D. The bolts are pilot drilled for greasing spring eye bushings. The 5/8th” bolt diameter fits perfect to the I.D. of the poly bushings! This eliminates the sleeves used with the 7/16th” original size bolts, [as seen in photos below] allowing for a smoother quieter ride, firmer steering- less play, and less problems with bushing sleeves rusted to the bolts, causing squeeks, and disassembly difficulties.

These 5/8th” bolts even when pilot drilled, are a lot stronger than a non drilled 7/16th” dia. bolt!

The 7/16th when drilled are only as strong as a 1/4 SAE Grade 5 bolt! Which is why so many break! This larger diameter 5/8″ bolt prevents bolt breakage, -a common occurence with greasable 7/16th bolts from other manufacturers.

A broken spring eye bolt on front springs can lead to loss of steering control! The 5/8th” bolts are made to order, according to the shackle plate thickness and width – so the grease hole is centered between the poly bushing halves.

The bolt head is indexed to allow for ease of aligning the grease hole. [yellow paint on bolt head and flank, over triple hash marks on the head]

The grade 8 flanged stover locknuts are cadmium plated for corrosion resistance, and no washers are needed.

These larger bolts are perfect for that worn out spring perch/shackle elongated hole!

A 7/16th” bolt in worn holes causes loose steering and tracking, so these 5/8th” bolts are a surefire BETTER fix to a problem.

The bolts have a shoulder/grip the full width of the spring eye perch/shackle for less wear to the hole in the shackle or perch and maximum strength of the bolt. [Threaded portions of a bolt aren’t as strong as unthreaded portions.]
