Extreme Pro Series 4-Link Housing Brackets for Billet Adjustable Shock Mounts

Quarter-Max's Extreme Pro Series 4-link housing brackets are manufactured in-house to high quality specifications with precise hole locations and smooth profiles.

With 19 holes of adjustment, these housing brackets provide you with more adjustability than any bracket on the market. These brackets feature a hole spacing of .625 in. for a finer range of adjustment than our pro series brackets.

Designed to be used with our billet adjustable shock mounts:
• RJ-300002 Billet Adjustable Double Shear Shock Mounts, 3/4 in. Wide
• RJ-300000 Billet Adjustable Threaded Shock Mounts, 3/4 in. Wide

Specifications:
• Thickness: 1/4 in.
• Material: 4130
• Axle Tube Hole Size: 3-1/2 in.
• Hole Spacing: .625 in.
• 4-Link Bolt Size: 1/2 in.

1/8 in. thick 4130 upper and lower doubler plates are available to increase the thickness around the holes to 3/8 in. for added strength and longevity.

During installation while mocking up and welding, we recommend the use of grade 8 bolts with our 4-link jigs to hold the brackets together in the correct position. After all the welding is complete, we recommend reaming the holes using our 7 piece chucking reamer kit #RJ-219850 and upgrading to our NAS 4-link bolt kit during final assembly for a tight fitment and even less bolt movement. Do not use a drill bit!
