1955-59 Chevy 3100 Truck Suspension Parts
A 2nd Series 3100 can keep the leaf-spring layout that has supported it for decades or take a very different path at the rear axle. POL's focused selection covers both directions, with stock and lowered multi-leaf suspension packages alongside an axle flip kit, complete 4-link system, king pins, tie rod ends, and related 4-link hardware.
Two Rear Suspension Paths for 1955-59 Chevy/GMC 3100
This seven-product collection revolves around one major decision: keep the rear leaf springs or replace that layout with a 4-link system.
Keeping the leaf-spring architecture opens two Stage 2 paths, one at stock ride height and another for a lowered truck. An axle flip and rear-end conversion kit takes the lowered route further by changing the axle position relative to the springs.
The 4-link system starts from a completely different rear suspension concept. A complete 1955-59 kit replaces the leaf-spring locating arrangement, with a Johnny Joint option available for builders taking that route.
At the front, the collection stays focused on service rather than conversion. King pins and replacement-style tie rod ends address wear in the original-style front end, making them separate from the much larger decision happening at the rear of the truck.
FAQ
What suspension parts are in the 1955-59 Chevy 3100 collection?
The collection currently contains seven products: replacement tie rod ends, a rear-end conversion and axle flip kit, a complete rear 4-link suspension kit, king pins, a lowered Stage 2 multi-leaf suspension kit, a stock-height Stage 2 multi-leaf suspension kit, and a Johnny Joint option for rear 4-link suspension.
Can I keep the leaf-spring suspension on a 1955-59 Chevy 3100?
Yes. POL currently offers Stage 2 multi-leaf suspension packages in both stock and lowered configurations. These provide two routes for trucks retaining a leaf-spring-based suspension rather than converting the rear to a 4-link.
Is there a lowered suspension kit for a 1955-59 Chevy truck?
Yes. A Stage 2 multi-leaf suspension kit specifically configured for lowered 1955-59 Chevy/GMC trucks is currently listed. POL also carries a separate rear-end conversion and axle flip kit for this generation.
Can a 1955-59 Chevy 3100 be converted to 4-link rear suspension?
POL lists a complete 1955-59 Chevy/GMC truck 4-link suspension kit in this collection. A Johnny Joint option for rear 4-link suspension is also available separately. Check the requirements and configuration of the complete system before choosing related components.
Are king pins available for 1955-59 Chevy 3100 trucks?
Yes. POL lists a king pin set specifically for 1955-59 Chevy/GMC 2nd Series 3100 trucks. This is one of the few front-end service products currently included in this particular suspension collection.
Does this collection include Mustang II suspension or air ride?
Not in the current seven-product assortment. Although the existing collection description mentions Mustang II suspension, air ride, shocks, and sway bars, the live product grid does not currently contain those categories. POL sells some of those products elsewhere on the site.
What should I decide before ordering suspension parts for a 1955-59 3100?
Establish the rear suspension plan first. Determine whether the truck will retain leaf springs, whether stock or lowered ride height is intended, and whether an axle flip is involved. If converting to 4-link suspension, check the rear axle and mounting requirements separately. For front-end service, inspect the king pins and tie rod ends currently installed.
