Fitment & Ordering Notes
Automotive lift manufacturers may use different parts across model years, production runs, or equipment revisions.

Additional Existing Product / Fitment Information
In the drawing images above this is part number 14 in the DP10-Parts new style w lock covers drawing and part number 8 in the I10 drawing and part number 8 in the I10111000 drawing.
Fits the following lift models — part number 143537 appears in the parts breakdown of each of these lifts: Rotary Lift DP10 (new style with lock covers), I10N000M; Forward Lift I10, I10 (111000), INT10, INT9, DP9A-S, DP10 10K Two-Post.
This wave spring is part of the arm restraint assembly shown in Figure 17 of the Section 3 parts breakdown. It provides the spring tension that keeps the arm restraint mechanism engaged, so the swing arms stay locked in position when a vehicle is raised. A fatigued or broken spring lets the restraint disengage too easily, a safety issue that should be corrected right away.
