Description
1350-series aluminum weld yoke for 4.000×0.083 tube with 3.844″ butt diameter and 1.875″ centerline-to-weld.
Q: Why is the 3526-4830 CL-to-weld (1.875") shorter than the 3526-40A (1.750" shown)?
A: The 3526-4830 uses a 0.083" wall (3.844" butt, 1.875" CL) while the 3526-40A uses a 0.125" wall (3.757" butt, 1.750" CL). At thicker wall, the yoke pilot seats shallower due to the smaller bore -- producing a shorter effective CL. The 0.125" wall version (3526-40A) has a shorter CL because the tube bore is smaller and the yoke's weld shoulder arrives at the tube face sooner. This is consistent CL scaling behavior across the wall-thickness variants.
Q: Which aluminum 4.000" tube 1350 variant should I choose?
A: For standard performance street builds: 0.125" wall (3526-40A) provides better impact resistance. For weight-optimized club racing: 0.083" wall (this part, 3526-4830) saves meaningful rotating mass. Both use the 1350-series U-joint. Calculate your required shaft length to determine which CL variant matches your tube stock.
Q: Is the 1350 joint appropriate for 4.000" tube in high-power applications?
A: The 1350 series is adequate for most normally aspirated V8 street cars at 4.000" tube. For forced-induction applications above 600 lb-ft, upgrade to the 1410 aluminum yoke family (4126-405A or 4126-41A) to maintain a conservative safety margin at this tube size.
