After Market Wheels for Older GM Trucks

Thursday, February 11th, 2010

From 1934 to 1959 GM 1/2 tons came from the factory with a tie rod assembly that extended side to side to almost touch the front wheels. With everything stock, the tie rod sits about 3/4 inch from the inside of both original six hole wheels and all fits just right.

A problem exists when someone attempts to add a more modern wheel. For example, the mid 60’s and newer 4×4 wheels have this 6 hole bolt pattern but their width causes them to contact the end of original long tie rod. Changing from the approximate 4-1/2 inch original to at least a 6 inch width just won’t work.

Solutions for adding a more sporty wheel are very limited with the original suspension. One almost unknown method is to replace the original GM multi-piece tie rod ends with the more modern knuckle ends introduced in the 1960’s. There are currently available and are 3/8 inch shorter on the outer end giving that much extra room for a slightly wider wheel. (It is not recommended that flat washers be placed over the stud between the wheel and drum as this can cause breakage.)

This GM six bolt pattern is also shared with several Japanese pickups. Some very attractive more narrow aftermarket wheels have been produced for their imports in past years.
