Cub Cadet Extension Spring 732-1184 RZT LT1040 LT1042 Troy-Bilt Mustang OEM

Cub Cadet Extension Spring 732-1184 RZT LT1040 LT1042 Troy-Bilt Mustang OEM.

Restore Proper Deck Belt Tension & Eliminate Belt Slippage: Genuine MTD Spring

Eliminate glazed drive belts, thrown deck belts, slow blade tip speeds, and uneven grass striping on your lawn tractor or zero-turn mower. This Genuine Cub Cadet / MTD Factory OEM Extension Spring (Part Number 732-1184 / 932-1184) is the authentic heavy-duty idler tension spring engineered explicitly for Cub Cadet RZT, SLT, GT, and LT 1000-series mowers, alongside Troy-Bilt Mustang XP, Pony, Horse, and Bronco models . Operating a cutting deck with a stretched or fatigued tension spring allows the drive belt to slip under load, robbing your blades of cutting power when entering thick turf.

Instead of gambling with universal hardware-store springs that lack the correct spring rate, wire diameter, or tensile yield strength, installing this authentic factory component ensures true OEM belt tracking. Manufactured by MTD from high-tensile, heat-treated alloy spring steel, this heavy-duty extension spring is engineered to withstand continuous cyclic vibration and high-load mechanical extension. Measuring . 84 inches in outer diameter by 4. 6 inches in overall length, it features heavy-duty offset hook ends designed to anchor firmly into factory deck bracket eyelets without bending or snapping under sudden blade engagement shocks, finished with a corrosion-resistant dichromate plating to resist moisture, grass acids, and rust.

This authentic factory replacement component is cataloged under Cub Cadet / MTD OEM Part Number 732-1184 (7321184 / Extension Spring / Deck Belt Tension Spring) and directly cross-references / replaces OEM Part Number 932-1184 (9321184) .
