Rear Four Link Kit – Triangulated

Posted December 18th, 2010

Rear Four Link Kit - Triangulated

Triangulated four link kits, with the option of standard or big bushing kits.

$340.00 — $390.00

GM has used a triangulated rear four link in many of their cars for decades. The design eliminates the Panhard bar. To accommodate many frame widths, the formed upper frame brackets may need to be trimmed. Bars are 1″ heavy-wall seamless tubing, tapped one end 3/4-16 (or 5/8-18 for the standard bushing kit) and notched for the urethane bushing tube on the other end. Upper bars are about 18″ c-c and lower bars are about 25″ c-c. Coil-overs can be mounted in one of three holes on the axle brackets. Assembly and installation tips are provided.

Two triangulated four link kits are offered, both are complete kits with the following variations:
318500 (available welded and ready-to-weld)
1-3/4″ wide, 1-5/8″ OD urethane bushings
3/4-16 threaded adjusters

218500 (available welded only)
1-3/8″ wide, 1-3/8″ OD urethane bushings
5/8-18 threaded adjusters

The bracketry for each kit is matched to the OD of the bushing for a clean appearance.

NEWS: The 1-3/8″ bushing, ready-to-weld kit has been discontinued. We will continue to produce welded 1-3/8″ bushing kits, but now at the same price as the larger bushing kits.

    DO YOU HAVE A TRIANGULATED 4 BAR FOR 1952 CHEVY TRUCK

    I’m looking to install a triangulated 4-link on my 51 chevy 3100 street rod project using a GM 12-bolt posi-rear out of a 71 monte carlo. Can your kit connect the upper bars to the dog ears on the 12-bolt instead of welding your upper axle tabs?

    Can you please tell me the length of the upper and lower arms, how far are the threaded, Can much could i shorten them.
    . The radius cuts – will they fit a ford 9”, and does the kit have grease nipples or any kind of lubing setup to stop squeaking? Thanks

      Lee, the upper arms are about 18″ c-c, the lowers about 25″. The thread is about 2″ deep. The brackets are made to fit a 3″ diameter tube. There is no provision for lubricating the urethane bushings. We suggest trying a product called SilGlide.

      Thanks for looking at Welder Series parts.

    Will your triangulated 4 link work with your step notch on a 97 s10 frame?

    Hi DW,
    Love this site/store!
    I’m looking at your 4-link and was wondering what exactly comes unwelded if I order it like that? I’m assuming it’s just the frame brackets so you can mount them in various ways.

      Hi Mike, thanks for your comment. The unwelded kit hasn’t been touched by a welder- the frame brackets, like you say, are unwelded, as are the adjusters, bars, and axle bracket support blocks.

      Thanks again, please let us know if you have any more questions.

    Has your triangulated 4 link been used on an Early Ford Econoline (1961-1967)? I am interested in putting a 4 link with a 9″ Ford under my Econoline Pickup.

    Thanks
