Elgin Industries Pushrod Manufacturing
Elgin Industries engineers have developed a very sophisticated manufacturing process that allows us to produce multiple types of push rods simultaneously. We have several dedicated production lines specific to our OE customers and aftermarket products. We have production lines dedicated to welded end push rods and pressed end push rods and even a hybrid line for combination of pressed and welded ends. Because of all these dedicated production lines, Elgin has the capability to produce over 150,000 push rods every day. Elgin employees are highly skilled and trained in our manufacturing processes and perform periodic product inspections to ensure all push rods meet tolerances.
We have developed a unique welding system designed to hold lengths of our push rods to +/- .13mm. We can manufacture lengths ranging from 5-1/2” to 12” using either standard 1010 steel or 4130 chrome-moly. Our wall thicknesses range from a stock .060” tube to .137” in our 3/8” One Piece Push Rods. We utilize a centerless grinder and hard turning for our One Piece Thick all Push Rods to achieve a 210 degree radius on the ends for extreme lift and high performance camshaft profiles and will hold up to virtually any valve spring load.
500 Series Pushrods
- All 500 Series push rods feature 5/16” diameter and
.075” wall thickness giving you 20% greater column strength than stock push rods. - Manufactured from heavy wall 1010 carbonitrited steel tube for exceptional wear. Greater than 55 RC
hardness. Deep case carburized 1018 steel ball ends with greater than 60 RC hardness. Rated for spring
pressures up to 400 lbs.
700 Series Pushrods
- Manufactured from 4130 seamless chrome moly nitrocarburized to greater than 60 RC hardness and
feature .065” wall thickness. Available in 5/16”, 3/8” and 11/32” diameters. Ideal for spring pressures greater
than 300 lbs.
One Piece Thick Wall Pushrods
- Manufactured from 4130 aircraft quality seamless chrome moly.
- Centerless ground and fully hard turned 210° radius ends.
- Through hardened and carburized tube with greater than 58 RC hardness and held to .005” maximum runout.
- Up to 40% greater column strength for superior strength and durability and increased stiffness to virtually eliminate compression and deflection which could lead to valve float and possibly catastrophic failure.
- Black oxide coated
