Quarter-Max's Extreme Pro Series 4-link chassis brackets are manufactured in-house to high quality specifications with precise hole locations and smooth profiles. With 16 holes of adjustment, these chassis brackets provide you with more adjustability than any fixed chassis bracket on the market. These brackets feature a hole spacing of .625" for a finer range of adjustment than our pro series brackets. These brackets feature notches for 1-5/8" crossmembers. The center of the top crossmember to center of the bottom crossmember is either 13" or 15”.

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. Af
