Description

Challenger 31023 U-Shape Slotted Carriage Guide Block for Older Challenger and Ammco 2-Post Lifts

This listing is for one (1) U-shape slotted carriage guide block (rub block / slider block) for older Challenger and Ammco 2-post lifts. The block rides inside the column of the lift, guiding carriage movement and keeping the carriage properly aligned as it travels up and down. This block is SLOTTED — it has a slot running down the middle with a metal plate insert, forming a U-shape. Most models require 16 blocks per lift (8 per carriage/side). Replace when the carriage feels loose or sloppy during operation.

Fitment and Ordering Notes

Always verify your exact lift model and block style before ordering. Critical Warning: Some Challenger and VBM models use a combination of slotted (U-shape) and solid rub blocks — for example, some 36000, 37000, and 39000 series lifts use 4 slotted and 4 solid blocks per carriage. Confirm which style is installed in the inside and outside corners of your specific lift before ordering. If blocks have dropped out of the carriage or the carriage remains sloppy after replacing standard-size blocks, oversized blocks may be required instead. Not sure which style your lift uses? Call us at 866-902-6060 before ordering.

Additional Product Information

Material is UHMW (ultra-high molecular weight polyethylene) with a metal insert, machined to OEM specifications. Dimensions are approximately 2-7/8″ x 1-1/4″ x 1-1/4″. Worn or missing slider blocks are a common cause of sloppy carriage movement on older Challenger-style 2-post lifts. Replacing the full set of 16 at once is recommended to restore proper carriage alignment and smooth operation.
