Pro Series 4-Link Chassis Brackets for Round Tube Back-Halfs, 4130

Quarter-Max's Pro Series 4-link chassis brackets were designed to hold up to high horsepower and have been race proven on RJ Race Cars for years. They are manufactured in-house to high quality specifications with precise hole locations and smooth profiles.

These brackets feature qty (8) 1/2 in. top holes and qty (5) 1/2 in. bottom holes for a wide range of 4-link tuning adjustability. The brackets also feature a hole spacing of .800 in. instead of the normal 1 in. spacing to allow for a finer range of adjustment.

Specifications:
• Thickness: 1/4 in.
• Material: 4130
• Hole Spacing: .800 in.
• 4-Link Bolt Size: 1/2 in.
• Application: Round tube back-halfs

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!
